Bolañitos Project | Executive Summary

1. | EXECUTIVE SUMMARY

1.1 | Introduction

Hard Rock Consulting, LLC (“HRC”) was retained by Endeavour Silver Corp. (“EDR”) to complete an independent technical audit and to update the mineral resource and reserve estimates for the Bolañitos Project (the “Project”) located in Guanajuato State, Mexico. This report presents the results of HRC’s efforts, and is intended to fulfill the Standards of Disclosure for Mineral Projects according to Canadian National Instrument 43-101 (“NI 43-101”). This report was prepared in accordance with the requirements and guidelines set forth in Companion Policy 43-101CP and Form 43-101F1 (June 2011), and the mineral resources and reserves presented herein are classified according to Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards - For Mineral Resources and Mineral Reserves, prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council on May 10, 2014. The mineral resource and mineral reserve estimates reported here are based on all available technical data and information as of December 31, 2016.

1.2 | Property Description and Ownership

In 2007, EDR acquired the Bolañitos mine from Industrias Peñoles S.A. de C.V. (Peñoles), the owner at the time, and Minas de la Luz, S.A. de C.V. (Minas de la Luz), the operator at the time. The acquisition included the Mina Cebada, Mina Bolañitos, Mina Golondrinas and Mina Asunción (as well as a few other currently closed mines). Minas de la Luz continued as the operator of the mines until June, 2007, when EDR assumed control. The Mina Asunción is very close to the Mina Bolañitos and the two are currently connected underground.

The Bolañitos Project is located in the state of Guanajuato, Mexico. The mine consists of three operating mines: the Bolañitos, Lucero, and Asuncion mines, which are located near the town of La Luz, about 12 km to the northeast of Guanajuato. All of the mines are readily accessed by paved and gravel roads. EDR also owns the inactive Cebada mine, located about 5 km north of the city of Guanajuato, and the inactive Golondrinas mine, which is 3.5 km to the southwest of Cebada.

1.3 | Geology and Mineralization

The Bolañitos mine is located in eastern part of the Guanajuato mining district, in the southeastern portion of the Sierra de Guanajuato, which is an anticlinal structure about 100 km long and 20 km wide. Bolañitos is located on the northeast side of this structure where typical primary bedding textures dip 10° to 20° to the north-northeast. Economic mineralization at Bolañitos is known to extend as much as 250 m vertically from 2300 m to 2050 m elevation with the exception of the La Luz vein that extends 400 m vertically from 2300 m to 1900 m.

The Guanajuato mining district is characterized by classic, high grade silver-gold, epithermal vein deposits with low sulfidation mineralization and adularia-sericite alteration. Veins in the Guanajuato district are typical of most epithermal silver-gold vein deposits in Mexico with respect to the volcanic or sedimentary host rocks and the paragenesis and tenor of mineralization. The Guanajuato mining district hosts three major mineralized fault systems, the La Luz, Veta Madre and Sierra systems.

Of the geological formations associated with the Guanajuato district, only the Esperanza and La Luz Formations occur in the Bolañitos mine area with mineralization residing primarily within the La Luz Formation. Mineralization is known to dissipate at the contact with the Esperanza Formation.

| 1 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Executive Summary

The Veta Madre historically was the most productive vein in the Guanajuato district, and is by far the most continuous, having been traced on the surface for nearly 25 km. The vein dips from 35° to 55º to the southwest with measured displacement of around 1,200m near the Las Torres mine and 1,700 m near La Valenciana mine. The most productive veins at Bolañitos strike parallel to the Veta Madre system.

Bolañitos mineralization is directly related to faulting. Mineralization occurs as open-space fillings in fracture zones or impregnations in locally porous wall rock. Veins which formed in relatively open spaces are the main targets for mining.

Mineralized veins at Bolañitos consist of the classic banded and brecciated epithermal variety. Silver occurs primarily in dark sulfide-rich bands within the veins, with little mineralization within the wall rocks. The major metallic minerals reported include pyrite, argentite, electrum and ruby silver, as well as some galena and sphalerite, generally deeper in the veins. Mineralization is generally associated with phyllic (sericite) and silicification alteration which forms haloes around the mineralizing structures. The vein textures are attributed to the brittle fracturing-healing cycle of the fault-hosted veins during and/or after faulting.

Economic concentrations of precious metals are present in “shoots” distributed vertically and laterally between non-mineralized segments of the veins. Overall, the style of mineralization is pinch-and-swell with some flexures resulting in closures and others generating wide sigmoidal breccia zones.

1.4 | Status of Exploration

In 2016, EDR spent US $240,249 (including property holding costs) on exploration activities, including drilling, at the Bolañitos Project. The target areas explored at the Bolañitos Project in 2016 included:

| • | Bolañitos North (La Luz-San Antonio de los Tiros),
| • | La Loba Margaritas, and
| • | Bolañitos South (San Cayetano and Emma)

A combined total of 9 drillholes were completed in the Bolañitos North (4 holes) and Bolañitos South (5 holes) areas for a total of 2,528 meters. Geological mapping and surface sampling was conducted in all three of the areas explored.

1.5 | Mineral Resource Estimate

Resource geologist Zachary J. Black, SME-RM, of HRC is responsible for the mineral resource estimate presented here. Mr. Black is a Qualified Person as defined by NI 43-101, and is independent of EDR. EDR estimated the mineral resource for the Bolañitos mine Project based on drillhole data constrained by geologic vein boundaries under the direct supervision of HRC. Datamine Studio RM® V1.0.73.0 (“Datamine”) software was used to audit the resource estimate in conjunction with Leapfrog Geo® V.3.0.0 (“Leapfrog”), which was used to produce a geologic model. The metals of interest at Bolañitos are gold and silver.

The Bolañitos mineral resource is comprised of 21 individual veins. The veins are further subdivided into areas and modeling method. The mineral resources have been estimated using either a Vertical Longitudinal Projection (VLP) polygonal method (9 veins) or as 3-dimensional (“3D”) block model (12 veins). The 3D models have been split into 2 areas based on the vein location within the deposit.

| 2 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Executive Summary

The resources based on the 2D polygonal methods are estimated by using a fixed distance Vertical Longitudinal Projection (VLP) from sample points. The VLPs are created by projecting vein geology and underground workings onto a vertical 2D long section. Resource blocks are constructed on the VLP based on the sample locations in the plane of the projection. EDR geologists review the data for sample trends and delineate areas with similar characteristics along the sample lines. The areas are then grouped based on mining requirements and the average grades and thicknesses of the samples are tabulated for each block. Resource volumes are calculated from the delineated area and the horizontal thickness of the vein, as recorded in the sample database. The volume and density are used to determine the overall resource tonnage for each area, and the grades are reported as a length weighted average of the samples inside each resource block.

HRC validated the vein models provided by EDR using Leapfrog. Ten veins were modeled by EDR using a series of cross-sectional interpretations. The sectional interpretations are based primarily on composite intercepts and are used to construct 3D vein solids in Vulcan. Cross-sections orthogonal to the strike of the vein and level plan sections were used to insure sample selections for compositing were contained within the modeled veins. HRC confirmed the areas reported in EDR resource sheets loading AutoCAD® long VLP’s provided by EDR into ArcGIS® software, and tracing the perimeter of the resource blocks and measuring the area with the built-in measuring tool. The dip of the vein and true thickness are known variables.

The mineral resource estimate for the Bolañitos Project as of December 31st, 2016, is summarized in Table 1-1. The mineral resources are exclusive of the mineral reserves.

| 6. | Mineral resources are estimated exclusive of and in addition to mineral reserves.

1.6 | Mineral Reserve Estimate

Mr. Jeff Choquette, P.E., MMSA QP Member, of HRC is responsible for the mineral reserve estimate presented in this report. Mr. Choquette is Qualified Person as defined by NI 43-101 and is independent of EDR. The reserve calculation for the Bolañitos Project was completed in accordance with NI 43-101 and has an effective date of December 31st, 2016. Stope designs for reporting the reserves were created utilizing the updated resources and cutoffs established for 2016. All of the stopes are within readily accessible areas of the active mining areas. Ore is processed in the on-site mill and floatation process capable of processing 1,600 tpd.

HRC utilized Datamine’s MSO (Mineable shape optimizer) program to generate the stopes for the reserve mine plan. The stopes were created based solely on Measured and Indicated resources above the calculated cutoff, which have demonstrated to be economically viable; therefore, Measured and Indicated mineral resources within the stopes have been converted to Proven and Probable mineral reserves as defined by CIM. Inferred mineral resources are classified as waste. Dilution is applied to Measured and Indicated resource blocks depending on the mining method chosen.

The mining breakeven cut-off grade, which includes internal stope dilution, was utilized in Datamine’s MSO to generate the stope designs for defining the reserves. The cut-off is stated as silver equivalent since the ratio between gold and silver is variable and both commodities are sold. The average cut-off grade used for the Bolañitos property is 162 g/t Ag equivalent. Silver equivalent grade is calculated as the silver grade + (gold grade * 75), taking into account gold and silver prices and expected mill recoveries.

Mineral reserves are derived from Measured and Indicated resources after applying the economic parameters as previously stated, and utilizing Datamine’s MSO program to generate stope designs for the reserve mine plan. The Bolañitos Project mineral reserves are derived and classified according to the following criteria:

| 4 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Executive Summary

| • | Proven mineral reserves are the economically mineable part of the Measured resource for which mining and processing / metallurgy information and other relevant factors demonstrate that economic extraction is feasible. For Bolañitos Project, this applies to blocks located within approximately 10m of existing development and for which EDR has a mine plan in place.
| • | Probable mineral reserves are those Measured or Indicated mineral resource blocks which are considered economic and for which EDR has a mine plan in place. For the Bolañitos mine project, this is applicable to blocks located a maximum of 35m either vertically or horizontally from development.

The Proven and Probable mineral reserves for the Bolañitos Project as of December 31, 2016 are summarized in Table 1-2. The reserves are exclusive of the mineral resources reported in Section 14 of this report.

1.7 | Conclusions and Recommendations

The QP considers the Bolañitos mineral resource and reserve estimates presented herein to conform with the requirements and guidelines set forth in Companion Policy 43-101CP and Form 43-101F1 (June 2011), and the mineral resources and reserves presented herein are classified according to Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards - For Mineral Resources and Mineral Reserves, prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council on May 10, 2014. These mineral resources and reserves form the basis for EDR’s ongoing mining operations at the Bolañitos Mines Project.

The QP is unaware of any significant technical, legal, environmental or political considerations which would have an adverse effect on the extraction and processing of the resources and reserves located at the Bolañitos Mines Project. Mineral resources which have not been converted to mineral reserves, and do not demonstrate economic viability shall remain mineral resources. There is no certainty that all or any part of the mineral resources estimated will be converted into mineral reserves.

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Executive Summary

The QP considers that the mineral concessions in the Bolañitos mining district controlled by EDR continue to be highly prospective both along strike and down dip of the existing mineralization.

EDR’s Bolañitos Mines Project has an extensive mining history with well-known silver and gold bearing vein systems. Ongoing exploration has continued to demonstrate the potential for the discovery of additional resources at the project and within the district surrounding the mine. Outside of the currently known reserve/resource areas, the mineral exploration potential for the Bolañitos Project is considered to be very good. Parts of the known vein splays beyond the historically mined areas also represent good exploration targets for additional resource tonnage.

Since EDR took control of the Bolañitos Mines Project, new mining areas have enabled EDR to increase production by providing additional sources of mill feed. EDR’s operation management teams continue to search for improvements in efficiency, lowering costs and researching and applying low-cost mining techniques.

In 2017, EDR will conduct a surface drilling program in the Bolañitos South and Bolañitos North areas. The planned program included 6,000 meters of drilling at an estimated cost of $900,000.

HRC recommends that the process of converting mineral resources into reserves from 2D polygons to 3D block models be continued. During the last couple of years, considerable progress has been made on this process with only nine veins remaining to be converted to 3D. Additional modeling efforts should be made to define the mineralized brecciated areas as they have been an important source of economic material encountered in the current operation, and could provide additional tonnage to support the mine plan.

EDR currently utilizes the exploration drilling and chip and muck samples in their resource and reserve calculations. HRC recommends that future efforts focus on constructing block models for resource and reserve reporting utilizing only the exploration and underground drilling results. The chip and muck samples should be used to develop the production model. This will help keep data densities consistent in each modeling effort and will provide another level in the reconciliation process to compare modeling results.

Although the reconciliations conducted by EDR show good comparison between planned versus actual values, the reconciliation process should be improved to include the estimated tonnes and grade from the resource models. Because the LOM plan is compared to the plant production on a monthly basis, the actual physical location of the material mined may be different than the planned location. Due to the many stopes that are mined during a day this can only be completed on an average monthly basis due to blending of stope material into the mill. The monthly surveyed as mined areas should be created into triangulation solids and saved on a monthly basis for reporting the modeled tonnes for each month. The combination of the 3D block models and 2D and polygonal reserves makes this process difficult but considerable progress has been made during the last year to get all resources and reserves into 3D block models. The model-predicted results versus actual can then be used to determine if dilution factors need to be adjusted, or perhaps the resource modeling parameters may require adjustment if there are large variances. The mill production should be reconciled to the final concentrate shipments on a yearly basis, and resulting adjustment factors should be explained and reported.

Bolañitos Project | Accessibility, Climate, Local Resources, Infrastructure & Physiography

5. | ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY

5.1 | Access and Climate

Primary access to the Bolañitos Project is provided by a newly constructed (2013) paved road from the city of Guanajuato. The Leon/Guanajuato international airport provides international access to the area with daily service from Los Angeles, Dallas/Fort Worth, Houston and Mexico City.

The regional climate is temperate, with cool winters and mild summers. Rainfall occurs primarily during the summer season, from June to September, and typical annual precipitation is about 50 cm per year. From mid-December through January, nighttime temperatures fall to 7° to 10 °C, and daytime high temperatures in low 20 °C range are typical. Snowfall is rare but has been known to occur at the higher elevations throughout the region. Weather conditions rarely, if ever, restrict mining activity at Bolañitos, and operations can be carried out year-round.

5.2 | Local Resources and Infrastructure

The capital city of Guanajuato has a population of approximately 160,000 and hosts several universities and post-secondary schools, including a mining college. Tourism is a principal industry in the area, and numerous hotels and restaurants are available as a result. The area has a rich tradition of mining and there is an ample supply of skilled personnel sufficient for both the underground mining operations and the surface facilities. Most of the work force resides in local communities or in the city of Guanajuato. Supplies required for the exploration programs and mining operations are purchased in either the city of Guanajuato or Leon.

At each of the mine site on the Bolañitos Project, the water required for operations is supplied from dewatering of the mines. The tailings facility at the Bolañitos mine is set up to recycle as much water as possible back into the processing plant.

Power supply to the Bolañitos Project is provided by the national grid CFE (Comisión Federal de Electricidad), and telephone communications are integrated into the national land-based telephone system which provides reliable national and international direct dial telephone communications. Satellite communications also provide phone and internet capabilities at the Bolañitos mine, though the satellite phone and internet services are slow and sometimes unreliable. There is no cell phone service at any of the mines.

Additional details regarding infrastructure specific to the Bolañitos Project are provided in Section 18 of this report.

5.3 | Bolañitos Mine Physiography

The state of Guanajuato is situated along the southern edge of the Central Mexican Plateau and comprises portions of the Trans-Mexican Volcanic Belt, the Mexican Plateau, and the Sierra Madre Oriental. The Bolañitos Project is located in the west central portion of the state, among a series of low mountains which are part of the Sierra Madre Occidental. Grass, small trees and shrubs along with several varieties of cacti make up most of the vegetation on the steeper hillsides, with larger trees found near springs and streams. The area is mainly devoid of trees except in the valleys and where reforestation has taken place.

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Accessibility, Climate, Local Resources, Infrastructure & Physiography

Even though there is a reasonable amount of rainfall each year, most of the creeks in the area are usually dry, with the exception of man-made reservoirs surrounding the city of Guanajuato. Some cattle and/or goat grazing is carried out in the area over the scrub land. Sections of more arable land have been deforested to support small plots for growing crops.

5.4 | Surface Rights

EDR has negotiated access and the right to use surface lands sufficient for many years of operation. Sufficient area exists at the Bolañitos Project for all anticipated future surface infrastructure. Details regarding surface rights for mining operations, availability of power sources, potential tailings storage areas, potential waste disposal areas, and potential processing plant sites, are discussed in the relevant sections of this report on mining methods, recovery methods and project infrastructure.

Bolañitos Project | History

6. | HISTORY

The following paragraphs provide an abbreviated timeline of the history of Bolañitos Project:

| • | 1968 - Fresnillo Company acquired claims and incorporated Negociación Minera Santa Lucía (now Cebada) and the Peregrina mine.
| • | 1973 - The contracting company Tormex S.A. completed a photogeological study in the area of the Cebada mine holdings.
| • | 1976 – Production began at the Cebada mine; between 1976 and 1995, the Cebada mine produced 1,277,216 tonnes at an average grade of 4.04 g/t gold and 372 g/t silver.
| • | 2003 - Grupo Guanajuato closed the Torres, Sirena, Peregrina and Apolo mines. The Bolañitos, Golondrinas, Asunción and Cebada mines stayed in production on a break-even basis.
| • | 2007 - EDR acquired the Bolañitos Project, which included, Mina Cebada, Mina Bolañitos, Mina Golondrinas and Mina Asunción (as well as a few other currently closed mines), from Peñoles, the owner at the time, and Minas de la Luz, the operator at the time. Minas de la Luz was kept on as the operator of the mines until June, 2007, when EDR assumed control.

6.1 | Historical Exploration

Records from the mining operations provide surveyed information of the historical workings and channel sample data from stopes, raises and drifts excavated on the mineralized zones. Limited drilling on the properties has been conducted during the past 20 years, and none during the 10 years before EDR took control. Several well mineralized and high-grade drill holes completed by Peñoles have not yet been followed-up, and these contribute to the remaining exploration potential for the property, which includes untested areas both along the strike of the veins and at depth below the old workings.

6.2 | Historical Production

In 2006, previous operator Minas de la Luz reported production of 255,766 oz silver and 3,349 oz gold from 76,532 tonnes of ore grading 128 g/t silver and 1.62 g/t gold from the Bolañitos, Cebada and Golondrinas mines, with the Bolañitos plant operating at about 43% of its capacity.

6.3 | Historic Mineral Resource and Reserve Estimates

Bolañitos Mineral resource and reserve estimates which were produced prior to EDR’s involvement with the Bolañitos Project are not discussed in this report as they are historical in nature, were not completed according to modern reporting standards, and are not considered reliable or relevant to the present-day Project.

7. | GEOLOGICAL SETTING AND MINERALIZATION

The following description of the geological setting for the Bolañitos Project is largely excerpted and modified from the technical reports prepared by Micon (2009, 2010, 2011 and 2012). HRC has reviewed the geologic data and information available, and finds the descriptions and interpretations provided in these documents acceptable for use in this report.

7.1 | Regional Geology

The mining district of Guanajuato is situated along the southern and eastern flanks of the Sierra Madre Occidental geological province, a north-northwesterly trending linear volcanic belt of Tertiary age. It is approximately 1,200 km long and 200 to 300 km in width. Rocks within the belt comprise flows and tuffs of basaltic to rhyolitic composition with related intrusive bodies. The volcanic activity that produced the bulk of the upper volcanic group ended by the late Oligocene, though there was some eruptive activity as recently as 23 Ma (early Miocene). The volcanism was associated with subduction of the Farallon Plate and resulted in accumulations of lava and tuffs on the order of 1 km thick. Later Basin and Range extensional tectonism related to the opening of the Gulf of California resulted in block faulting, uplift, erosion and the present-day geomorphology of the belt. Strata within the belt occupy a broad antiform, longitudinally transected by regional scale faults. A regional geologic map of the Bolañitos Project area is presented as Figure 7-1.

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Geological Setting and Mineralization

The Guanajuato district is underlain by a volcano-sedimentary sequence of Mesozoic to Cenozoic age rocks. There are three main northwest trending vein systems that cut these volcano-sedimentary sequences. The vein systems from west to east are known as the La Luz, Veta Madre and La Sierra systems. These systems are generally silver-rich with silver to gold ratios from 72:1 to 214:1. They are known along strike for 10 to 25 km.

The Bolañitos mine is located in eastern part of the Guanajuato mining district, in the southeastern portion of the Sierra de Guanajuato, which is an anticlinal structure about 100 km long and 20 km wide. Bolañitos is located on the northeast side of this structure where typical primary bedding textures dip 10° to 20° to the north-northeast. Economic mineralization at Bolañitos is known to extend as much as 250 m vertically from 2300 m to 2050 m elevation with the exception of the La Luz vein that extends 400 m vertically from 2300 m to 1900 m.

| 7.1.1 | Stratigraphy

The stratigraphy of the Guanajuato mining district can be divided into a Mesozoic basement (Chiodi et al, 1988; Dávila and Martinez, 1987; Martinez-Reyes, 1992) and overlying Cenozoic units, as shown in Figure 7-2. The lower Mesozoic lithological units are the Esperanza and La Luz Formations which are composed of marine sedimentary rocks, weakly to moderately metamorphosed and intensely deformed by shortening. These rocks are unconformably overlain by the Tertiary Guanajuato Formation conglomerates, and the Loseros, Bufa, Calderones, Cedros and Chichíndaro Formations. The Tertiary rocks consist of continental sediments and sedimentary rocks, which generally occupy lower topographic zones, and subaerial volcanic rocks, which are principally exposed in the ranges and higher plateaus. The rocks of the Cenozoic cover have experienced only extensional deformation and in some places are gently tilted. Tertiary-aged rocks correspond to a period of tectonism accompanied by volcanism and intrusive magmatic activity.

Figure 7-2 does not depict the Peregrina intrusive, which is a floored body (laccolith) at the contact of the Bufa Formation rhyolite and the Guanajuato Formation conglomerate. The uppermost portion of the Peregrina intrusive extends into the Chichíndaro Formation rhyolite. The thickness of each unit presented graphically in the stratigraphic section represents the maximum thickness of that unit in the vicinity of the Bolañitos mine.

| 7.1.2 | Esperanza Formation

The Esperanza Formation is composed of carbonaceous and calcareous shale interbedded with arenite, limestone, and andesitic-to-basaltic lava flows, all weakly metamorphosed to phyllites, slates, and marble. The thickness of the formation exceeds 600m.

| 7.1.3 | La Luz Formation

The La Luz Formation overlies the Esperanza Formation and consists mainly of interbedded clastic sedimentary rocks and massive and pillow tholeiitic basalts dated at 108.4 ±2 Ma. Locally, rhyolite tuffs and agglomerates are present, and some volcanogenic massive sulfide occurrences have been reported. A minimum thickness of at least 1,000 m is recognized, but the true thickness is unknown due to deformation and sub-greenschist metamorphism. Included with the La Luz Formation are the La Palma diorite and La Pelon tonalite, which form the upper part of the Guanajuato arc. Pervasive propylitic alteration is common.

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Geological Setting and Mineralization

| 7.1.4 | Guanajuato Formation (Eocene to Oligocene)

The red conglomerate characteristic of the Guanajuato Formation lies in unconformable contact with the Esperanza Formation and less frequently with the La Luz Formation andesite (Edwards, 1955). The conglomerate consists of pebbles to boulders of quartz, limestone, granite and andesite belonging to older rock units, all cemented by a clay matrix, with some interlayers of sandstone. Beds of volcanic arenites and andesitic lavas occur at the base of the conglomerate. The Guanajuato conglomerate is estimated to be between 1,500 and 2,000 m thick. Contemporaneous vertebrate paleontology and andesitic lavas (49 Ma, Aranda-Gómez and McDowell, 1998) indicate that the unit is mid-Eocene to early Oligocene in age.

| 7.1.5 | Loseros Formation (Cenozoic)

This overlying mid-Tertiary volcanic sequence is interpreted to be within, and adjacent to a caldera. The Loseros tuff is a well-bedded, green to cream-red volcanic arenite from 10 m to 52 m thick. It is interpreted to be a surge deposit at the base of the Cubo caldera filling and Oligocene in age.

| 7.1.6 | Bufa Formation (Cenozoic)

The Bufa Formation rhyolite is a felsic ignimbrite that is approximately 360 m thick and lies above a sharp to gradational contact. It is a sanidine-bearing rhyolite-ignimbrite with biotite as a mafic phase, and is often massive, but locally bedded. Owing to moderate welding and extensive and pervasive silicification, it is a hard rock that forms prominent cliffs east of the city of Guanajuato. It occasionally contains large lithic clasts of various types, many of which were derived from the pre-volcanic basement. At Bolañitos, the Bufa rhyolite has three mappable units: a lower breccia overlain by dense, red rhyolite porphyry, in turn overlain by a massive to bedded ignimbrite. The cliff-forming Bufa rhyolite has been dated using the K-Ar dating technique to be 37 ±3 Ma, placing it in the middle Oligocene.

| 7.1.7 | Calderones Formation (Cenozoic)

The Calderones Formation contains a wide variety of volcanic rocks, including low- to medium-grade ignimbrites, deposits of pyroclastic flows, pyroclastic surge layers related to phreatomagmatic activity, airfall ash-rich tuffs, minor Plinian pumice layers, lahars, debris flows, reworked tuffaceous layers deposited in water, tuff-breccias and mega-breccias. Ubiquitous and characteristic chlorite alteration imparts a green to greenish blue color to almost all outcrops of the Calderones. Propylitic alteration adjacent to veins and dikes is of local importance in many outcrops.

The Calderones Formation overlies the Bufa Formation at Bolañitos with a contact marked by a megabreccia composed of large (often 5 to 10 m) fragments of the Esperanza, La Luz and Guanajuato Formations. The Calderones Formation, which exceeds 300 m in thickness at Bolañitos, is the upper caldera-filling unit above the surge deposit and the Bufa ignimbrites.

| 7.1.8 | Cedros Andesite (Cenozoic)

Overlying the Calderones Formation is the Cedros Formation andesite, a 100 to 640-m thick unit, which consists of grey to black andesitic lava flows with interlayered red beds and andesitic to dacitic tuffs.

The Cedros Formation is entirely post-caldera and is widespread.

| 7.1.9 | Chichíndaro Formation (Cenozoic)

The Chichíndaro Formation rhyolite is a sequence of domes and lava flows interbedded with poorly sorted volcanic breccias and tuffs. Fluidal porphyritic textures are characteristic in the domes and flows.

This lithologic unit is closely related to the hypabyssal Peregrina intrusion, and it ranges in thickness from 100 to 250 m. In places, the rhyolite domes contain disseminated tin and vapor-phase cavity-filling topaz distributed along the flow foliation.

The Chichíndaro rhyolite is the youngest volcanic unit in the Guanajuato mining district. Three K-Ar ages obtained from this formation (Gross, 1975; Nieto- Samaniego et al, 1996) date the unit at 32 ±1 Ma, 30.8 ±0.8 Ma and 30.1 ±0.8 Ma.

| 7.1.10 | Comanja Granite (Cenozoic)

The Comanja granite is a unit of batholithic size, apparently emplaced along the axis of the Sierra de Guanajuato. It is Eocene in age and has been radiometrically dated at 53 ±3 Ma and 51 ±1 Ma by K-Ar in biotite (Zimmermann et al, 1990). These dates establish the youngest relative age for the Bufa formation, the youngest unit cut by the granite.

| 7.1.11 | El Capulin Formation

The unconsolidated El Capulin Formation consists of tuffaceous sandstone and conglomerate overlain by vesicular basalt, all of Quaternary age.

7.2 | Structure

The following paragraphs are modified from the summary of the structural setting of the Guanajuato mining district presented by Starling (2008), which focused on the Veta Madre but likely applies to the La Luz system that composes the Bolañitos mine.

Pre-mineralization deformation during the Laramide orogeny (~80-40 Ma) resulted in west-northwest trending pre-mineral folds and thrusts in the Esperanza Formation as observed in the Cebada mine on the Veta Madre. Early post-Laramide extension (~30 Ma) was oriented north-south to north-northeast, and controlled many vein deposits in the region (e.g. Fresnillo, Zacatecas, La Guitarra). Guanajuato appears to lie on a north-northwest-trending terrane boundary which was reactivated as a sinistral transtensional fault zone in conjunction with early stage intermediate-sulfidation style mineralization. Subsequent (~28 Ma) regional extension to the east-northeast-west-northwest resulted in basin and range-type deformation and block faulting, and is associated with a second phase of mineralization in the Guanajuato district.

Along the Veta Madre vein system, ore shoots were controlled during early-stage mineralization by counter-clockwise jogs along the main structure and at intersections with west-northwest and northeast fault zones. These tended to generate relatively steep ore shoots plunging to the south along the Veta Madre.

During the second phase of mineralization, listric block faulting and tilting affected parts of the Veta Madre veins and new systems such as La Luz developed. The veins at La Luz appear to have formed as extensional arrays between reactivated west-northwest fault zones acting as dextral transtensional structures.

| 24 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Geological Setting and Mineralization

The second phase vein systems tend to have formed sub-horizontal ore zones either reflecting fluid mixing zones or structural controls due to changes in dip of the fault surface. The overprint of two events means that in some deposits ore shoots have more than one orientation and that there are vertical gaps in ore grade.

Randall et al (1994) first proposed a caldera structure as a conceptual geologic model for the Guanajuato mining district, citing the presence of a mega-breccia in the Calderones Formation and the distribution of the Oligocene volcanic formations described above. The hypothesis states that the caldera collapse occurred in at least two stages and the collapse was a trap-door type. The presence of a peripheral three-quarter ring of rhyolite domes intruding along bounding faults, the location of the Oligocene volcanic formations ponded within this ring, mega-breccia and topographic rim, all provide supporting evidence for this hypothesis.

Following caldera formation, normal faulting combined with hydrothermal activity around 27 Ma (Buchanan, 1980) resulted in many of the silver-gold deposits found in the district. Within the Guanajuato mining district there are three major mineralized fault systems, the La Luz, Veta Madre, and Sierra systems. Veta Madre is a north-northwest trending fault system and the largest at 25 km long. The other systems are subparallel to it. Mineralization occurs within these systems principally on normal faults oriented parallel to the main trend.

7.3 | Local Geology

Of the geological formations associated with the Guanajuato district only the Esperanza and La Luz Formations occur in the Bolañitos mine area with mineralization residing primarily within the La Luz Formation. Mineralization is known to dissipate at the contact with the Esperanza Formation (Figure 7-3).

Bolañitos Project | Geological Setting and Mineralization

The Veta Madre historically was the most productive vein in the Guanajuato district, and is by far the most continuous, having been traced on the surface for nearly 25 km. The vein dips from 35° to 55º to the southwest with measured displacement of around 1,200m near the Las Torres mine and 1,700 m near La Valenciana mine. The most productive veins at Bolañitos strike parallel to the Veta Madre system.

Bolañitos mineralization is directly related to faulting. Mineralization occurs as open-space fillings in fracture zones or impregnations in locally porous wall rock. Veins which formed in relatively open spaces are the main targets for mining.

There are 21 veins within the Bolañitos mine area that are included in the mineral resource estimate. These mineralized veins are known to occur from an elevation of 2300 m down to an elevation of 1900 m (Figure 7-4).

| 7.3.1 | Alteration

The hydrothermal alteration of the wall rock is prevalent in the Guanajuato District, and is an excellent guideline in the mining prospection of Bolañitos. Alteration within the district is closely related to fractures, veins and brecciated zones. Alteration halos surrounding these zones range from a few centimeters to meters and can be divided into 4 alteration types: 1) propyllitic, 2) argillic, 3) phyllic, and 4) silicification.

Wall rock alteration at Bolañitos in general is not significantly altered at the depths of mineralization; however, breccia zones within and near the primary structures do have the typical characteristics of low sulphidation epithermal vein type alteration. Alteration encountered within the structures forms halos of phyllic (sericite) and silicification alteration. Argillic and propyllitic alteration have been identified above the mineralized level of 2300 m.

| 27 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Geological Setting and Mineralization

Propyllitic alteration is the most widely distributed type and the strongest near fractures, especially in the intersections of veins. The propyllitic alteration consists of epidote, chlorite, clays and calcite. Phyllic (sericite) alteration is not as pervasive as the propyllitic alteration, and is generally encounter within or in immediate contact with the vein. The typical mineral assemblage of this type of alteration consists of pyrite, illite and sericite with occasional kaolinite and montmorillonite. Argillic alteration consists of kaolinite, montmorillonite, and halloysite. Silicification is restricted to vein and breccia zones, and typically extends only a few centimeters into the wall rock.

7.4 | Mineralization

Mineralized veins at Bolañitos consist of the classic banded and brecciated epithermal variety. Silver occurs primarily in dark sulfide-rich bands within the veins, with little mineralization within the wall rocks. The major metallic minerals reported include pyrite, argentite, electrum and ruby silver, as well as some galena and sphalerite, generally deeper in the veins. Mineralization is generally associated with phyllic (sericite) and silicification alteration which forms haloes around the mineralizing structures. The vein textures are attributed to the brittle fracturing-healing cycle of the fault-hosted veins during and/or after faulting (Figure 7-5).

Figure 7-5 Lucero Vein in the Bolañitos Mine

Economic concentrations of precious metals are present in “shoots” distributed vertically and laterally between non-mineralized segments of the veins. Overall, the style of mineralization is pinch-and-swell with some flexures resulting in closures and others generating wide sigmoidal breccia zones.

Primary economic mineralization at Bolañitos is gold and silver. Bolañitos is postulated to be a low sulphidation system with pyrite but no arsenopyrite.

The silver-rich veins of Bolañitos contain quartz, adularia, pyrite, acanthite, naumannite and native gold. Native silver is widespread in small amounts. Much of the native silver is assumed to be supergene. Silver sulfosalts (pyrargyrite and polybasite) are commonly found at depth.

8. | DEPOSIT TYPES

The following description of the mineral deposit type associated with the Bolañitos mine property is excerpted from the technical report prepared by Cameron (2012). HRC has reviewed the geologic data and information available, and finds the descriptions and interpretations provided herein reasonably accurate and suitable for use in this report.

The Guanajuato silver-gold district is characterized by classic, high grade silver-gold, epithermal vein deposits with low sulfidation mineralization and adularia-sericite alteration. The Guanajuato veins are typical of most epithermal silver-gold vein deposits in Mexico with respect to the volcanic or sedimentary host rocks and the paragenesis and tenor of mineralization.

Epithermal systems form near the surface, usually in association with hot springs, and to depths on the order of a few hundred meters. Hydrothermal processes are driven by remnant heat from volcanic activity. Circulating thermal waters rising through fissures eventually reach a level where the hydrostatic pressure is low enough to allow boiling to occur. This can limit the vertical extent of the mineralization, as the boiling and deposition of minerals is confined to a relatively narrow range of thermal and hydrostatic conditions. In many cases, however, repeated healing and reopening of host structures can occur, imparting cyclical vertical movement of the boiling zone and resulting in mineralization that spans a much broader range of elevation.

As the mineralizing process is driven by filling of void spaces and fissures, mineralization geometry is affected by the permeability and orientation of the host structures. Mineralization tends to favor dilatant zones in areas where fractures branch or change orientation, which may be driven, in turn, by wall rock competency and/or relative hardness of individual strata.

Low-sulfidation epithermal veins in Mexico typically have a well-defined, sub-horizontal ore horizon about 300 m to 500 m in vertical extent, where high grade ore shoots have been deposited by boiling hydrothermal fluids. The minimum and maximum elevations of the mineralized horizons at the Bolañitos mine have not yet been established precisely, but historic and current production spans an elevation range from 1900 to 2300 m.

Low-sulfidation deposits are formed by the circulation of hydrothermal solutions that are near neutral in pH, resulting in very little acidic alteration with the host rock units. The characteristic alteration assemblages include illite, sericite and adularia that are typically hosted either by the veins themselves or in the vein wall rocks. The hydrothermal fluid can travel along discrete fractures creating vein deposits, or it can travel through permeable lithology such as poorly welded ignimbrite flows, where it may deposit its load of precious metals in a disseminated fashion. In general, disseminated mineralization is found some distance from the heat source. Figure 8-1 illustrates the spatial distribution of the alteration and veining found in a hypothetical low-sulphidation hydrothermal system.

Bolañitos Project | Drilling

10. | DRILLING

Diamond drilling at the Bolañitos Project is conducted under two general modes of operation: one by the exploration staff (surface exploration drilling) and the other by the mine staff (production and underground exploration drilling). Production drilling is predominantly concerned with definition and extension of the known mineralized zones in order to guide development and mining. Exploration drilling is conducted further from the active mining area with the goal of expanding the resource base. Drilling results from both programs were used in the mineral resource and mineral reserve estimates presented in this report. To date, all drilling completed at the El Cubo mine has been diamond core.

10.1 | Surface Drilling Procedures

Surface drillholes are generally oriented to intersect the veins as close to perpendicular as possible. The drillholes are typically drilled from the hanging wall, perpendicular to, and passing through the target structure into the footwall, and no drilling is designed for intercepts with angles less than about 30° to the target. Drillholes extend an average of 50 m beyond the target zone.

Underground drillholes are typically drilled from the hanging wall, and are ideally drilled perpendicular to structures, but oblique intersection is required in some instances due to limitations of the drill station. Underground positive angled holes (up holes) are generally drilled from the footwall using the same criteria. All holes are designed to pass through the target and into the hanging or footwalls. Both surface and underground drillholes are typically HQ to NQ in size.

On the drill site, the drill set-up is surveyed for azimuth, inclination and collar coordinates, with the drilling subject to daily scrutiny and coordination by EDR geologists. Since 2010, surface holes are surveyed using a Reflex multi-shot down-hole survey instrument normally at 50 m intervals from the bottom of the hole back up to the collar. At underground drill stations, azimuth orientation lines are surveyed in prior to drilling. Inclination of underground holes is collected using the Reflex EX-Shot® survey device prior to starting drilling.

The survey data obtained from the drillholes are transferred to databases in Vulcan® and AutoCAD®, and are corrected for local magnetic declination, as necessary. Information for each drillhole is stored in separate folders.

Drill core is collected daily and is transported to the core logging facility under EDR supervision. The core storage facilities at El Cubo are well protected by high level security fences, and are under 24-hour surveillance by security personnel to minimize any possibility of tampering with the dill cores.

When assay results are received from the laboratory, they are merged into an Excel® spreadsheet for importation and interpretation in AutoCAD® software. The starting and ending point of each vein and/or vein/vein breccia intercept is determined from a combination of geology notes in the logs and assay results. Using approximate vein and drillhole orientation information a horizontal width is calculated for the intercept to be used as part of a Vertical Longitudinal Projection (“VLP”).

The center point of the intercept, horizontal width, and gold and silver assay values are plotted on VLPs of each vein. These are used to guide further drilling, interpret mineralization shoots, and as the basis of polygonal resource estimation.

10.2 | EDR Core Logging Procedures

As the core is received at the core facility, geotechnical data is logged manually on paper sheets and entered into Excel®. The core is then manually logged for geological data and marked for sampling. Geological data and sample information are entered directly into Excel® spreadsheets.

10.3 | EDR Drilling Programs and Results

| 10.3.1 | 2016 Drilling Summary

During 2016, a total of 2,528 m was drilled in 9 holes (surface diamond drilling) at the Bolañitos Project. Drilling was focused on the Bolañitos North (La Luz vein in the San Antonio de los Tiros area) and Bolañitos South (San Cayente and Emma veins) areas. A total of 544 samples were collected and submitted for assays. The summary of the activities undertaken during 2016 is shown in Table 10-1.

Drilling was conducted in the La Luz area in order to define potential mineralization south of and at similar elevation to the old workings of the San Bernabe area (elevation 1,950 to 2,100 masl). The La Luz vein was tested at a variety of elevations within a roughly 650 m horizontal area, but no significant intercepts were returned and as such no future drilling is being considered.

In the San Cayetano area drilling was conducted to identify potential mineralization to the northwest and above the level of the El Roble Adit, between the elevations 2,000 to 2,100 masl (El Roble Stope). The drilling program included 4 holes, covering a distance of 100 m laterally. The results of the drilling were generally negative, though EDR plans further exploration to test the structure below the level of El Roble Adit between two historic drill holes.

A single hole was drilled to test the Emma vein in order to see if future exploration might be warranted, but again no significant results were returned.

Bolañitos Project | Sample Preparation, Analyses and Security

11. | SAMPLE PREPARATION, ANALYSES AND SECURITY

The sample data relied upon during completion of the mineral resource and reserve estimates presented in this report are from diamond drill core and underground chip channel samples.

11.1 | Methods

| 11.1.1 | Production Chip Channel Samples

Bolañitos employs standardized procedures for collecting underground grade control chip samples, and these procedures are documented in a detailed, illustrated manual. Chip channel sampling is carried out daily in accessible stopes and development headings by mine sampling technicians. Samples are located by measuring with a tape from known survey points. The samples are taken perpendicular to the veins at 3m to 5m intervals along drifts. Sample locations are cleaned and marked with two parallel, red spray paint lines to guide the sampling. Chip samples are collected on all vein faces in drifts, crosscuts, raises, and stopes. On faces and raises they are taken perpendicular to the dip of the vein to approximate true width. Stopes are sampled across the roof (back) following the profile of the working.

The entire chip sample is divided into a number of discrete samples based on the geology (lithology). The simplest configuration is a single vein where the chip sample would be divided based on one sample of the wall rock on each side of the vein, and one sample of the vein. In more complex configurations, if there is more than one vein present, or it is divided by waste rock, then each of the vein sections is sampled separately. The chip samples are cut approximately 10 cm wide and 2 cm deep using a hammer and chisel. The rock chips are collected in a net, placed on a canvas, and any fragments larger than 2.5 cm are broken with a hammer. The maximum sample length is generally 1.5 m and minimum sample length is generally 0.2 m, though a few samples are taken over as narrow a width as 0.1 m.

The samples are sealed in plastic bags with a string and sent to the laboratory at Bolañitos. Samples which tend to be large, representing long sample intervals, can be too large for the bags provided and are reduced in size at the sample site to 1-2kg by quartering. Care is taken to collect all of the fines for the selected quarters. The samples are sealed in plastic bags and transported to the geology storage facility on surface. From there the samples are taken to the laboratory at the Bolañitos mine site by contracted transporter. Sample locations are plotted on stope plans using CAD software. The sample numbers and location data are recorded in a spreadsheet database. Upon receipt of assays, technicians and geologists produce reports used for day-to-day monitoring and grade control.

| 11.1.2 | Exploration Sampling

EDR’s exploration staff are responsible for regional and mine exploration within the Bolañitos mining district, including the management, monitoring, surveying, and logging of surface and underground diamond drilling.

Regardless of which program the core comes from, the process is the same. Core from diamond drilling is placed in boxes which are sealed shut at the drill site. EDR personnel transport the core to the core facility. Sample handling at the core facility follows a standard general procedure, during which depth markers are checked and confirmed; the outside of the boxes are labeled with interval information; core is washed and photographed; and the recovery and modified rock quality designation (RQD) are logged for each drillhole.

| 44 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Sample Preparation, Analyses and Security

All of EDR’s surface and underground exploration drillholes are processed at the exploration core facility.

A cutting line is drawn on the core with a colored pencil, and sample tags are stapled in the boxes or denoted by writing the sample number with a felt tip pen.

The core is split using a diamond saw.

11.2 | Sample Preparation and Analysis

Mine production sampling including plant feed samples, concentrate and doré, are sent to EDR’s in-house, ISO-certified Bolañitos assay laboratory. The laboratory is set up in a single facility at the Bolañitos mine with separate enclosed sections for sample preparation, fire assay with gravimetric finish, and atomic absorption facilities. The facilities are located within the Bolañitos mine compound and operate 24 hours per day.

| 11.2.1 | Exploration Drilling 11.2.1

All samples of rock and drill core are bagged and tagged at the Guanajuato core facility and shipped to the ALS preparation facility in Zacatecas, Mexico. After preparation, the samples are shipped to the ALS laboratory in Vancouver, Canada, for analysis.

Upon arrival at the ALS preparation facility, all of the samples are logged into the laboratory’s tracking system (LOG-22). Then the entire sample is weighed, dried if necessary, and fine crushed to better than 70% passing 2 mm (-10 mesh). The sample is then split through a riffle splitter and a 250-g split is then taken and pulverized to 85% passing 75 microns (-200 mesh).

The analysis procedures are summarized in Table 11-1.

ALS is an independent analytical laboratory company which services the mining industry around the world. ALS is also an ISO-certified laboratory that employs a rigorous quality control system in its laboratory methodology as well as a system of analytical blanks, standards and duplicates. Details of its accreditation, analytical procedures and QA/QC program can be found at http://www.alsglobal.com.

In 2016, the average turn-around time required for analyses was approximately 2 weeks.

11.3 | Sample Quality Control and Quality Assurance

| 11.3.1 | Production Sampling

Sample quality assurance procedures underground include careful marking of the sample lines across the faces or backs of the heading, recording measurements from known points to accurately locate the samples, and measuring each sample length with a tape. Samples are collected carefully onto a canvas, conserving all material. Oversize pieces are broken up, then the sample is rolled, coned, and quartered at the sample site to reduce sample volume. Samples remain in the custody of the technicians and geologists who collected them until they are delivered to designated sample storage areas on surface. Samples are collected from each storage area by a contracted transporter and delivered to the assay lab on site at the Bolañitos mine.

Field duplicate samples are inserted at the frequency of about 1 in 20 chip lines. The last sample taken is a duplicate sample. The sample interval to be duplicated is chosen at random from one of the vein intervals. Waste duplicates are not collected. The sample is collected from a point approximately 10cm above the original sample. Duplicate samples are sent with the rest of the samples from the chip line.

| 11.3.2 | Production Samples

The QA/QC protocol for production samples involves repeat assays on pulp and reject assays, along with in-house prepared blanks. No commercially available standards were used in 2016.

Maximum-minimum scatter plots for duplicate samples are shown in Figure 11-1 through Figure 11-6. In general, results of the duplicate re-assays indicate a good correlation for silver and moderate to poor correlation for gold. Acceptable failure rate for pulp duplicates is 10%. Silver pulps show a 6% failure rate while gold shows a 42% failure rate.

Acceptable failure rate for reject duplicates is 20%. Silver rejects show a 12% failure rate while gold shows a 33% failure rate.

Finally, failure rate for mine duplicates is 30%. Silver duplicates show a 26% failure rate while gold shows a 45% failure rate.

Silver pairs with a mean value of 10x the detection limit were excluded. Gold pairs with a mean value of 15x the detection limit were excluded. The higher gold failure rate may be caused by low precision near the origin. Eliminating pairs that are close to detection will reduce the failure rate. Overall the results are acceptable but could be improved.

Check assaying is performed to check the precision and accuracy of the primary laboratory, and to identify errors due to sample handling. Check assaying consists of sending pulps and rejects to a secondary lab for analysis and comparison against the primary lab.

No check assays from mine production were sent to secondary labs for analysis in 2015.

Coarse blanks monitor the integrity of sample preparation and are used to detect contamination during crushing and grinding of samples. Blank failures can also occur during laboratory analysis or as the result of a sample mix-up. A blank analysis ≥4 times the detection limit is considered a blank failure.

EDR submitted 614 coarse pulp blanks to the Bolañitos mine Laboratory to monitor sample preparation during 2015. Blank samples had a failure rate of 1.5% and 3.3% for silver and gold, respectively.

| 11.3.3 | Surface Exploration Samples

During 2015, surface and underground drilling was supported by a QA/QC program conducted to monitor the integrity of all assay results. Each batch of 20 samples included one blank, one duplicate and one standard. Check assaying is also conducted at a frequency of approximately 5%. Discrepancies and inconsistencies in the blank and duplicate data are resolved by re-assaying the pulp, reject or both.

In 2016, a total of 544 samples, including control samples, were submitted during the drilling exploration program at Bolañitos. A summary of sample type and quantity is shown in Table 11-2. A total of 24 pulps (~5%) were also submitted for check assays.

The sampling process, including handling of samples, preparation and analysis, is shown in the quality control flow sheet, Figure 11-7.

| 11.3.3.1 | Sample Preparation and Analysis

Blank samples were inserted to monitor possible contamination during the preparation process and analysis of the samples in the laboratory. Commercial Enviroplug Coarse (1/4”) bentonite was used as the blank material. Blank samples are inserted randomly into the sample batch and given unique sample numbers in sequence with the other samples before being shipped to the laboratory.

Blank samples were inserted at an average rate of approximately 1 for each 20 original samples. The control limit for blank samples is 10 times the minimum limit of detection of the assay method of the element: 0.05 ppm for gold and 2.5 ppm for silver. Figure 11-8 and Figure 11-9 plot the blank analysis results for gold and silver, respectively.

| 11.3.3.2 | Exploration Duplicate Samples

Duplicate samples are used to monitor (a) potential mixing up of samples and (b) variability of the data as a result of laboratory error or the lack of homogeneity of the samples.

Duplicate core samples were prepared by EDR personnel at the core storage facility. Randomly selected sample intervals are prepared for duplicate analysis. The duplicates are then sampled by splitting the core in half in the same manner as a normal sample, before crushing and splitting the sample into two equal portions. Both samples are submitted to the laboratory as individual samples with unique sample numbers for analysis. Duplicates are submitted at a ratio of one duplicate sample in every 20 samples submitted for analysis.

Discrepancies and inconsistencies in the duplicate sample data are resolved by re-assaying either the pulp or reject or both. For the duplicate samples, graphical analysis shows moderate correlation index for gold (0.88) and 0.92 correlation index for silver (correlation coefficients above 0.90 are considered satisfactory). Scatter plots for gold and silver are presented as Figure 11-10 and Figure 11-11, respectively.

| 11.3.3.3 | Standard Reference Samples

EDR uses commercial reference standards to monitor the accuracy of the laboratories. Standard reference material (SRM) has been purchased from CDN Resource Laboratories Ltd. Each reference standard was prepared by the vendor at its own laboratories and shipped directly to EDR, along with a certificate of analysis for each standard purchased.

| 53 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Sample Preparation, Analyses and Security

In 2016, a total of 39 standard reference control samples were submitted at an average frequency of 1 for each batch of 20 samples. Reference standards were ticketed with pre-assigned numbers in order to avoid inadvertently using sample numbers that were being used during logging.

Two different standards were submitted and analyzed for gold and silver. Reference standard information for 2016 is summarized in Table 11-3.

For graphical analysis, results for the standards were scrutinized relative to the mean or control limit (CL), and a lower control limit (LL) and an upper control limit (UL), as shown in Table 11-4.

Table 11-3 Reference Standards Used for Endeavour Silver’s Surface Drilling Programs

Reference Standard | Reference Number | Reference Source | Reference Standard Assays (Certificate) | Reference Standard Assays (Calculated)
Gold (g/t) | Silver (g/t) | Gold (g/t) | Silver (g/t)
edr-41 | CDN-GS-2Q | Cdn Resource Lab | 2.37 | 73 | NA | NA
edr-45 | CDN-ME-1505 | Cdn Resource Lab | 1.29 | 360 | NA | NA

Table 11-4 Basis for Interpreting Standard Sample Assays

Limit | Value
UL | Plus 2 standard deviations from the mean
CL | Recommended or Calculated value (mean) of standard reference material)
LL | Minus 2 standard deviations from the mean

EDR’s criteria for a batch failure include:

| • | A reported value for a standard greater than 3 standard deviations from the mean is a failure.
| • | Two consecutive values of a standard greater than 2 standard deviations from the mean is a failure.
| • | A blank value over the acceptable limit is a failure.

Results of each standard were reviewed separately. Most values for gold and silver were found to be within the control limits, and the results are considered satisfactory. The mean of the ALS assays agrees well with the mean value of the standard. Examples of the control charts for the standard reference material generated by EDR are shown in Figures 11-12 through 11-15.

| 11.3.3.4 | Exploration Check Assaying

EDR periodically conducts check analyses in order to evaluate the accuracy of the primary laboratory. Random pulps selected from original core samples are sent to a second laboratory to verify the original assay and monitor any possible deviation due to sample handling and laboratory procedures. EDR employs the BSI-Inspectorate laboratory in Durango, Mexico, for check analyses.

Correlation coefficients are high (>0.99) for both silver and gold, indicating a high level of agreement between the original ALS assay and the BSI-Inspectorate check assay. Figures 11-16 and 11-17 show the correlations between the values of gold and silver respectively.

| • | Polygonal 2-dimensional long sections for veins Belen, HW Belen, Bolanitios, Old Bolañitos, Cebada, Golandrinas, La Joya, La Luz – San Barnabe, and Plateros with resource and reserve calculations.

12.1 | Database Audit

The surface drilling, underground drilling, and underground channel samples were combined into a single database for mineral resource estimation. HRC conducted a thorough audit of the current EDR exploration and operation sample databases. The following tasks were completed as part of the audit:

| • | Performed a mechanical audit of the database;
| • | Validated the geologic information compared to the paper logs;
| • | Validated the assay values contained in the exploration database with assay certificates from the EDR Bolañitos mine laboratory; and
| • | Validated the assay values contained in the 2D polygonal long sections by comparing with select, relevant historical assays and the original drawings.

HRC limited the audit to the rock-type, assay, drillhole collar, and survey data contained in the exploration database.

| 58 |

| 12.1.1 | Mechanical Audit

A mechanical audit of the combined database was completed using Leapfrog Geo® software. The database was checked for overlaps, gaps, duplicate channel samples total drillhole length inconsistencies, non-numeric assay values, and negative numbers. The following list of drillholes were missing information:

| • | No Assay Data

| o | Surface Drillholes

| • | LZ49-1A

| o | Underground Drillholes

| • | LAU12-08
| • | LAU12-09
| • | GAU-04

| • | No Lithology Data

| o | Surface Drillholes

| • | DN-51
| • | DN-52
| • | DN-53
| • | DN-54
| • | DN-55
| • | DN-56

| o | Underground Drillholes

| • | GAU-04

A total of 333 surface drillholes, 143 underground drillholes, and 10,007 underground channel samples were imported into leapfrog for validation. Data with missing information were not used in the estimation of mineral resources.

| 12.1.1.1 | Overlaps

Overlaps identified in the audit were corrected with EDR personnel.

| 12.1.1.2 | Gaps, Non-numeric Assay Values, and Negative Numbers

The software reported missing intervals for silver and gold. Below detection limit samples are reported as a non-positive value of 0. All of the non-positive numbers (<0) were assumed to be non-sampled intervals and were omitted from the dataset. No non-numeric assays were encountered in the audit. Table 12-1 below summarizes the number of intervals imported, the number of missing intervals, the number of non-positive values and the number of valid assays for each element.

Table 12-1 Database Import Summary

Element | Missing | Non-Positive Values | Assay Values
Ag (g/t) | 3,592 | 3,290 | 62,528
Au (g/t) | 3,592 | 5,369 | 64,762

| 12.1.1.3 | Table Depth Consistency

The survey, assay, and geology tables maximum sample depth was checked as compared to the maximum depth reported in the collar table for each drillhole. No intervals exceeded the reported drillhole depths.

Bolañitos Project | Data Verification

12.2 | Certificates

HRC received original assay certificates in excel format for the samples collected in 2015 in the current database. A random manual check of 10% of the database against the original certificates was conducted. The error rate within the database is considered to be less than 1% based on the number of samples spot checked.

12.3 | Adequacy of Data

HRC has reviewed EDR’s check assay programs and considers the programs to provide adequate confidence in the data. Samples that are associated with QA/QC failures are reviewed prior to inclusion in the production and exploration databases; however, in production there is not always sufficient time for corrective measures prior to exploitation of the stope being sampled. Improvements to the sampling procedures and QA/QC failure corrective measures may improve the overall sample quality of the production samples.

The laboratories are clean, well-documented, and appear to be working properly. HRC would however recommend that EDR install a Laboratory Information Management System (LIMS) to eliminate human error or correcting of values to an expected result. LIMS systems are proven to reduce errors in the sampling process that result in considerable money lost. This system will automate the QA/QC reporting for the geology department and the laboratory while reducing the time required to input data into a database for modeling.

Exploration drilling, sampling, security, and analysis procedures are being conducted in manner that meets or exceeds industry standard practice. All drill cores and cuttings from EDR’s drilling have been photographed. Drill logs have been digitally entered into exploration database organized and maintained in Vulcan. The split core and cutting trays have been securely stored and are available for further checks.

13. | MINERAL PROCESSING AND METALLURGICAL TESTING

13.1 | Mineralogical Analysis

A mineralogical analysis of the concentrate samples at the University of San Luis Potosi determined that:

| • | 60-80% of silver is as Aguilarite Ag2(S,Se) (grains of size 10-60 μm, 40% liberated),
| • | 15-45% of silver is as Pirargirite Ag3SbS3 (grains of size 10-40 μm)
| • | Up to 5% of silver is in Freibergite Cu12Sb4S12/Ag (grains of size 10-40 μm),
| • | Up to 5% of silver may be in Argentite Ag2S,
| • | Up to 0.5% of silver may be in Cerargirite AgCl, and
| • | Up to 10% of silver is in Electrum (3-90 μm) associated with Aguilarite, Pyrite, and Calcite.

13.2 | Gravity Concentration

In January 2013, preliminary gravity concentration tests were performed using a lab scale Falcon concentrator. The samples were taken from flotation tailings, cyclone underflow, and ball mill discharge. The tests were carried out at 60 to 300 earth gravity accelerations and water pressure 2 psi. Electrum was observed by naked eye in gravity concentrates in all tests. The best results were obtained at 60 gravity accelerations recovering 20% of silver and 36% of gold into a concentrate, however the concentrate grade (3.4% of feed weight) was low (209 g/t Ag and 8 g/t Au).

In 2014 it was decided to perform a test on a larger scale under the same conditions. On April 14, 2014, at the Bolañitos plant a test was a conducted by the Falcon staff. The test was completed on approx. 70 kg (100%) of flotation tails and obtained 274 g of primary concentrate (0.39%) . The primary concentrate was cleaned in the same Falcon concentrator and obtained 60 g (0.085%) of 2° clean concentrate. This concentrate was cleaned by a tentadura hand and obtained a concentrated final of 10.3 g (0.015%) with 258 g/t Ag and 20.8 g/t Au. The recovery of silver concentrate ultimately was 0.19% and gold was 1.1% . Based on these results, gravity concentration was found to be unprofitable. The estimated operating costs were three times the estimated increase in revenue. If lower operating costs, higher metal prices and a change in mineral with coarser gold materializes than the study should be reinvestigated.

13.3 | 13.3 Concentrate Sale vs. Cyanide Leaching

In 2008, EDR started processing the Bolañitos concentrate by cyanide leaching at the Guanaceví plant. The average recoveries were 88% of silver and 90% of gold. By the end of 2012, EDR found that concentrate sale was more economic than cyanide leach and began shipping to the concentrate traders.

13.4 | Comments on Section 13

The Bolañitos mines have a long history of successful operation and processing and have plans to continue. The QP is of the opinion that the level of metallurgical testing is appropriate for the duration of the life of the mine plan and is unaware of any processing factors or deleterious elements that could impact the potential economic extraction of metal from the Bolañitos mines ore.

14. | MINERAL RESOURCE ESTIMATES

Resource geologist Zachary J. Black, SME-RM, of HRC is responsible for the mineral resource estimate presented here. Mr. Black is a Qualified Person as defined by NI 43-101, and is independent of EDR. EDR estimated the mineral resource for the Bolañitos mine Project based on drillhole data constrained by geologic vein boundaries under the direct supervision of HRC. Datamine Studio RM® V1.0.73.0 (“Datamine”) software was used to audit the resource estimate in conjunction with Leapfrog Geo® V.3.0.0 (“Leapfrog”), which was used to produce a geologic model. The metals of interest at Bolañitos are gold and silver.

The mineral resources reported here are classified as Measured, Indicated and Inferred in accordance with standards defined by Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) “CIM Definition Standards - For Mineral Resources and Mineral Reserves”, prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council on May 10, 2014. Classification of the resources reflects the relative confidence of the grade estimates.

14.1 | Density

HRC applied a density of 2.61 t/m3 to convert volume into tonnage. The density is taken indirectly from the “NI43-101 Technical Report Resource and Reserve Estimates for the Bolañitos Mines Project Guanajuato State Mexico” dated February 25, 2015, and authored by Michael J. Munroe.

14.2 | Methodology

The Bolañitos mineral resource is comprised of 21 individual veins. The veins are further subdivided into areas and modeling method. The mineral resources have been estimated using either a Vertical Longitudinal Projection (VLP) polygonal method (9 veins) or as 3-dimensional (“3D”) block model (12 veins). The 3D models have been split into 2 areas based on the vein location within the deposit. Table 14-1 summarizes the vein by the modeling method and area.

14.3 | Vertical Longitudinal Projection

The resources based on the 2D polygonal methods are estimated by using a fixed distance Vertical Longitudinal Projection (VLP) from sample points. The VLPs are created by projecting vein geology and underground workings onto a vertical 2D long section. Figure 14-1 displays the VLP for the Belene veins. Resource blocks are constructed on the VLP based on the sample locations in the plane of the projection. EDR geologists review the data for sample trends and delineate areas with similar characteristics along the sample lines. The areas are then grouped based on mining requirements and the average grades and thicknesses of the samples are tabulated for each block. Resource volumes are calculated from the delineated area and the horizontal thickness of the vein, as recorded in the sample database. The volume and density are used to determine the overall resource tonnage for each area, and the grades are reported as a length weighted average of the samples inside each resource block.

| 64 |

| 14.3.1 | Composite Calculations

Composites for 2D estimates are calculated from underground channel samples taken perpendicular to the vein approximately every 3m along strike of the vein to determine variability in grade and thickness. The samples are grouped into a uniform composite length by using a length weighted average to determine the grade. A single or multiple composites are then used to determine the average grade of a resource block.

| 14.3.2 | Area and Volume Calculations

HRC confirmed the areas reported in EDR resource sheets loading AutoCAD® long VLP’s provided by EDR into ArcGIS® software, and tracing the perimeter of the resource blocks and measuring the area with the built-in measuring tool. The dip of the vein and true thickness are known variables. Volume is calculated by multiplying the area of the resource block by the horizontal thickness. The horizontal thickness is used for volume calculations to compensate for the reduction in area when translating the vein to a VLP (Figure 14-2).

| 14.3.3 | VLP Mineral Resource Classification

The 2D estimates were classified based on the distance to the nearest sample. Measured mineral resources are the area of the defined resource blocks within 10 meters of a sample. Indicated mineral resources are the area of the defined resource blocks within 20 meters of a sample. Inferred mineral resources are those blocks greater than 20 meters from a sample and have a value for estimated silver.

14.4 | 3D Block Model Method

| 14.4.1 | Geologic Model

HRC validated the vein models provided by EDR using Leapfrog. Ten veins were modeled by EDR using a series of cross-sectional interpretations. The sectional interpretations are based primarily on composite intercepts and are used to construct 3D vein solids in Vulcan. Cross-sections orthogonal to the strike of the vein and level plan sections were used to insure sample selections for compositing were contained within the modeled veins. Figure 14-3 and Figure 14-4 are 5-meter-thick sections (vertical and level plan, respectively) of the Karina vein with the composites displayed. The surfaces were evaluated in 3D to ensure that both the down dip and along strike continuity was maintained throughout the model. Figure 14-5 through Figure 14-10 show the modeled veins sub-divided into 3 areas from different viewing perspectives.

| 14.4.2 | Block Model

The 3D geologic solids were converted to block models using Vulcan. The model prototypes are rotated along strike and down dip and encompass the entire vein. Various block sizes were used along strike and down dip. The blocks for thickness were sub-blocked to the vein thickness. A summary of the block model parameters is shown in Table 14-2. The volume, tonnage, and average statistics for sample length, silver, and gold are presented in Table 14-3.

| 14.4.4 | Capping

Grade capping is the practice for replacing any statistical outliers with a maximum value from the assumed sampled distribution. This is done statistically to better understand the true mean of the sample population. The estimation of highly skewed grade distribution can be sensitive to the presence of even a few extreme values.

EDR utilized cumulative frequency plots, and sample statistics to determine appropriate capping values for silver and gold in each vein. HRC reviewed and confirmed these capping values. The final dataset for grade estimate in the block model consists of composites capped as presented in Table 14-5. Descriptive statistics for the capped silver and gold composites are presented in Tables 14-6 and 14-7, respectively.

| 14.4.5 | Variography

A variography analysis was completed by to establish spatial variability of silver and gold values in the deposit. Variography establishes the appropriate contribution that any specific composite should have when estimating a block volume value within a model. This is performed by comparing the orientation and distance used in the estimation to the variability of other samples of similar relative direction and distance.

Variography was analyzed by EDR for silver and gold. The subsequent variograms defining the maximum continuity were modeled with a spherical variogram. HRC reviewed the variogram model and as determined them to be acceptable for use in estimation. The variogram parameters for silver and gold are presented in Tables 14-8 and 14-9 respectively.

| 14.4.6 | Estimation Parameters

EDR used an ordinary kriging (“OK”) method to estimate the block models. The OK method was confirmed by HRC for reporting as a reliable fit with drillhole data throughout the models. The search ellipse parameters used for estimation are shown in Table 14-10.

Silver and gold grades were estimated in each vein by using a single search ellipse. The size, direction, and anisotropy of the search ellipse depended on the variography, and the number of composites.

| 14.4.7 | Model Validation

The Bolañitos models were validated by the following methods:

| • | Comparison of the global descriptive statistics from the Ordinary Krige (“OK”), Nearest Neighbor (“NN”), and composite data, and
| • | Inspection of the ID block model on long section in comparison to the composite grades.

| 14.4.7.1 | Comparison with Ordinary Krige and Nearest Neighbor Models

The NN model was run to serve as comparison with the estimated results from the OK method. Descriptive statistics for the OK method along with those for the NN, and drillhole composites for gold and silver are shown in Tables 14-11 through 14-12, and Tables 14-13 through 14-14, respectively.

The overall similarities of the statistical comparisons between the composites and models represent an appropriate amount of smoothing to account for the proposed narrow vein mining method with minimum dilution. The OK and NN models generally show similar means to the composites. The OK model has similar variance to the composites based on the Coefficient of Variation (“CV”). This is based on the stopes having similar statistics to the composites in operations; however, this will need to be continually examined as additional data is made available.

| 14.4.7.2 | Sectional Inspection

A visual comparison of block grades with drillhole and channel composites was made in long section. The block models follow the grade trends in the data with higher variability in the areas of denser sampling and additional smoothing of the estimate as the distance from data increases. Figures 14-12 and 14-13 display silver and gold long sections, respectively. Each long section is zoomed to a scale for viewing of the Daniela vein as estimated with the composites overlaying the block grades.

| 14.4.8 | Mineral Resource Classification

The mineral resource classification for Bolañitos has not changed since the previous Technical Report.

Measured resources are those blocks that reside up to 10 m from production sample data or halfway to adjacent data points, whichever is less.

Indicated resource blocks for the existing operations are within a maximum distance of 20 m from any data point including development, chip samples or drill hole intercepts. For the exploration division's polygonal resource estimates, a 25-m search radius is used in the definition of indicated resources.

Inferred mineral resources are those blocks/areas where confidence in the estimate is insufficient to enable an evaluation of the economic viability worthy of public disclosure. For the mining operations, these are outlined and estimated based on the mine's interpretation and confidence in the historical sampling results. For the exploration division's polygonal resource estimates, a 50-m search radius is used in the definition of inferred resources.

14.5 | Bolañitos Mineral Resource Statement

The mineral resource estimate includes all analytical data obtained as of December 31, 2016. Mineral resources are not mineral reserves and may be materially affected by environmental, permitting, legal, socio-economic, political, or other factors.

Mineral resources are reported above a silver equivalent grade of 162 gpt, assuming a silver price of $16.29 per ounce. HRC used a cutoff grade to test for reasonable prospects for economic extraction. Baseline assumptions for breakeven cutoff grade are based on Table 14-15:

| 89 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Mineral Resource Estimates

Table 14-15 Cutoff Grade Assumptions for Bolañitos Mine

Bolañitos Resource Cutoff
Ag $/oz Au $/oz | $16.29 $1,195.00
Concentrate Recovery Ag Concentrate Recovery Au | 79.6% 84.5%
Payable Ag Payable Au | 96% 96%
Mining Cost $/t Process Cost $/t G&A Cost $/t | $39.14 $13.19 $12.42
NSR Ag $/g NSR Au $/g | $0.40 $31.17
Mine Cutoff $/t | $64.75
Mine Cutoff AgEq g/t | 162

Based on these assumptions, HRC considers that reporting resources at a 162 g/t cutoff constitutes reasonable prospects for economic extraction based on the current mining method and demonstrated recoveries.

15. | MINERAL RESERVE ESTIMATES

Mr. Jeff Choquette, P.E., MMSA QP Member, of HRC is responsible for the mineral reserve estimate presented here. Mr. Choquette is Qualified Person as defined by NI 43-101 and is independent of EDR. The mineral reserve calculation was completed in accordance with NI 43-101 and has an effective date of December 31st, 2016. Stope designs for reporting the reserves were created utilizing the updated resources and cutoffs established for 2016. All of the stopes are within readily accessible areas of the active mining areas. Ore is processed in the on-site mill and floatation process capable of processing 1,600 tpd.

15.1 | CALCULATION PARAMETERS

HRC utilized Datamine’s Mineable Shape Optimizer (“MSO”) program to generate the stopes for the reserve mine plan. The parameters used to create the stopes are listed below;

| • | Cutoff Grade: 162 g/t AgEq
| • | Minimum Mining Width: 0.8 m.
| • | Cut and Fill Stope Size: 7m W x 4m H
| • | Long Hole Stope Size: 7m W x 20m H
| • | External Dilution Cut and Fill: 15%
| • | External Dilution Long Hole: 30%
| • | Silver Equivalent: 75:1 silver to gold
| • | Gold Price: US $1,195/oz
| • | Silver Price: US $16.29/oz
| • | Gold Recovery: 84.5%
| • | Silver Recovery: 79.6%

The stopes were only created with the updated Measured and Indicated resources including internal stope dilution above the calculated cutoff and have demonstrated to be economically viable, therefore Measured and Indicated mineral resources within the stopes have been converted to Proven and Probable reserves as defined by NI 43-101. All Inferred material has been classified as waste.

EDR also has ore grade stockpiles from current and past mining areas which are classified as part of the overall mineral reserve. These stockpiles are used frequently to balance the feed into the plant.

| 15.1.1 | Dilution

Dilution is applied to Measured and Indicated resource blocks depending on the mining method chosen. For blocks to be exploited using conventional cut and fill methods, external dilution was applied in the amount of 15% at a grade of zero. For blocks to be exploited using long hole methods, external dilution was applied in the amount of 30% at a grade of zero. Internal dilution is also applied based on any blocks that fall inside the stope shape but are below cutoff. A mining recovery is also applied to converted resources and is estimated at 95%. The overall result of these factors resulted in and overall dilution factor of 21.0% for Bolañitos.

There is no supporting documentation to support these dilutions or mining recovery estimates. HRC recommends that individual dilution and recovery studies be performed on various veins and types of reserve blocks to refine the global estimates used for dilution and mining recovery.

| 96 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Mineral Reserve Estimates

The global dilution and mining recovery factors at Bolañitos have varied over time depending on company philosophy and experience in reconciling estimated mine production with mill sampling. Dilution and mining recoveries are functions of many factors including workmanship, design, vein width, mining method, extraction, and transport. Currently, there is limited information upon which to measure actual dilution and recovery in the stopes, and transport system. The majority of stoping is now done using longhole methods. Without a cavity measuring survey instrument, measuring dilution in these types of stopes is problematic.

| 15.1.2 | Cutoff Grade

The mining breakeven cut-off grade was utilized in Datamine’s MSO to generate the stope designs for defining the reserves. The actual production cost data from the third quarter of 2016, reserve price assumptions, and mill recoveries are used to calculate the reserve breakeven cut-off grade. The parameters used for the calculation are presented in Table 15-1.

The cut-off is stated as silver equivalent since the ratio between gold and silver is variable and both commodities are sold. The average cut-off grade used for the Bolañitos Project is 162 g/t Ag equivalent. Silver equivalent grade is calculated as the silver grade + (gold grade * 75), taking into account gold and silver prices and expected mill recoveries.

| 15.1.3 | Reconciliation of Mineral Reserves to Production

Production monitoring and reconciliation of mineral reserves are the ultimate activities by which the mineral reserve estimate can continuously be calibrated and refined. The only valid confirmation of both the mineral resource and mineral reserve estimate is through appropriate production monitoring and reconciliation of the estimates with mine and mill production. Proper reconciliation is required to validate the mineral reserve estimates and allows a check on the effectiveness of both estimation and operating procedures. Reconciliations identify anomalies which may prompt changes to the mine/processing operating practices and/or to the estimation procedure.

The geology staff at Bolañitos prepare reconciliations of the Life of Mine plan (“LOM”) to actual production from sampling on a monthly basis.

| 97 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Mineral Reserve Estimates

The reconciliation compares the LOM with geology estimates from chip sampling and plant estimates based on head grade sampling. Reconciliation estimates a negative variance on tonnes for both geology and LOM as compared to the plant reported tonnes for 2016, this is mainly due to feeding of stockpiled ore during the year (Table 15-2). Estimated tonnage was 12% lower for geology and 29% higher for the plant than specified in the LOM. Silver equivalent grades were 10% lower for geology and 4% lower for the plant than specified in the LOM.

Table 15-2 2016 Mine to Plant Reconciliation

| LOM_2016 | Geology Short Term | Plant
Ore Mined | 393,479 | 344,740 | 507,704
Grade Au | 2.30 | 2.05 | 2.31
Grade Ag | 93 | 84 | 81
Grade AgEq | 272 | 244 | 261
Ounces Au | 29,114 | 22,762 | 37,676
Ounces Ag | 1,173,728 | 935,573 | 1,322,919
Ounces AgEq | 3,440,915 | 2,708,155 | 4,256,098

Although the reconciliations conducted by EDR show good comparisons on planned values versus actual values the reconciliation process should be improved to include the estimated tonnes and grade from the resource models. By comparing the LOM plan on a monthly basis to the plant production the actual physical location of the material mined may be different in the plan versus the actual area that was mined. Due to the many faces that are mined during a day this can only be completed on an average monthly basis due to blending of these areas into the mill. The monthly surveyed as mined areas should be created and saved on a monthly basis for reporting the modeled tonnes for each month. The model predicted results versus actuals can then be used to determine if dilution factors need to be adjusted or perhaps the resource modeling parameters may require adjustment if there are large variances.

15.2 | Reserve Classification

Mineral reserves are derived from measured and indicated resources after applying the economic parameters as stated previously and utilizing Datamine’s MSO program to generate stope designs for the reserve mine plan. The MSO stope designs are then used to design stopes on levels along with the required development for the final mine plans. The Bolañitos Project mineral reserves are derived and classified according to the following criteria:

| 98 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Mineral Reserve Estimates

| • | Proven mineral reserves are the economically mineable part of the Measured resource for which mining and processing / metallurgy information and other relevant factors demonstrate that economic extraction is feasible. For Bolañitos Project, this applies to blocks located within approximately 10m of existing development and for which EDR has a mine plan in place.
| • | Probable mineral reserves are those Measured or Indicated mineral resource blocks which are considered economic and for which EDR has a mine plan in place. For the Bolañitos mine project, this is applicable to blocks located a maximum of 35m either vertically or horizontally from development.

Figure 15-1 shows reserve blocks depicted on a portion of a typical longitudinal section. Proven reserve blocks are shown in red, Probable reserve blocks are shown in green. The mine planners have determined that extraction of the blocks is feasible given grade, tonnes, costs, and access requirements.

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Mineral Reserve Estimates

| 15.3.1 | Factors that may affect the Mineral Reserve Estimate

The Bolañitos operation is an operating mine with a relatively long history of production. The mine staff possess considerable experience and knowledge with regard to the nature of the orebodies in and around the Bolañitos property. Mine planning and operations need to continue to assure that the rate of waste development is sufficient to maintain the production rates included in the mine plan.

It is unlikely that there will be a major change in ore metallurgy during the life of the current reserves, as nearly all of the ore to be mined will come from veins with historic, recent, or current production.

The process of mineral reserve estimation includes technical information which requires subsequent calculations or estimates to derive sub-totals, totals and weighted averages. Such calculations or estimations inherently involve a degree of rounding and consequently introduce a margin of error. The QP does not consider these errors to be material to the reserve estimate.

Areas of uncertainty that may materially impact the mineral reserves presented in this report include the following:

| • | Mining assumptions,
| • | Dilution assumptions,
| • | Exchange rates,
| • | Changes in taxation or royalties,
| • | Variations in commodity price,
| • | Metallurgical recovery, and
| • | Processing assumptions.

16. | MINING METHODS

16.1 | Mining Operations

As of June, 2007, EDR assumed management of day-to-day mining operations at the Bolañitos Project, in order to allow for more flexibility in the operations and to continue optimizing the costs. As of December 31, 2016, the Bolañitos Project had a roster totaling 348 employees and an additional 191 contractors. The mine's operating schedule consists of three 8-hour shifts 7 days a week. The miners are skilled and experienced in vein mining and, according to EDR, the miners are currently unionized. There is an incentive system in place rewarding personnel for safety and production. Technical services and overall supervision are provided by EDR staff.

The mine employs geology, planning and surveying personnel and operates using detailed production plans and schedules. All of the mining activities are conducted under the direct supervision and guidance of the mine manager.

16.2 | Ground Conditions

The ground conditions at the Bolañitos and Lucero mines are considered to be good. The rocks are competent and require no special measures for support other than occasional rock bolting and regular scaling. At the Cebada mine, the ground conditions are similar to the other mines, with the exception of the hanging wall of the deposit which is comprised of a weak, laminated graphitic shale. The weak nature of the hanging wall material requires additional rock bolting. The current cut and fill mining method is well suited to these ground conditions. Cable bolting is required during the preparation of stopes for longhole blasting. The cable bolts are installed by drilling holes in the hanging wall and fixing the bolts in place with cement pumped into the hole.

16.3 | Mining Method

Conventional drill and blast methods are used to extract the ore at Bolañitos, and access to the mining areas is provided by ramps and audits. Mine development headings are drilled by jumbo and by jackleg. Traditionally a conventional bottom-up cut and fill mining method was employed with waste rock brought in using diesel or electric loaders. The rock used to backfill the stopes is either dropped down a bore hole from surface or is generated from the waste development underground. Over the past several years a transition to a modified long hole method has taken place wherever the width and dip of the vein is applicable to this method.

Once sill development is completed and the limits of the ore have been defined, stope production can begin. For conventional cut and fill stoping, ore is mined upward in horizontal slices using jackleg drills. Cut and fill mining is a method of short hole mining with hole lengths usually less than 2m. For long hole mining the holes are typically 10-12m in length but vary from 6 to 16m depending on the stope. Under certain circumstances concrete is used as fill to create a solid floor. This enables mining from the stope below up to the concrete pillar and recovering most, if not all of the ore pillar that would otherwise be left behind. This process is usually reserved for high-grade floor pillars.

For cut and fill the production cycle starts by drilling upper holes using a jackleg. Geologists mark up the vein, and the stope is drilled and blasted accordingly. Drillholes on the vein are blasted first. After the ore has been mucked, the holes drilled in waste are then blasted to achieve the dimensions required for the scoop to work in the next production lift.

| 103 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Mining Methods

By comparison, longhole open-stoping, holes are drilled upwards and/or downwards from the sill level. Longhole methods are typically 6 to 16m in length and are more productive than cut and fill methods. Longhole stoping is also cheaper than conventional cut and fill stoping. As with cut and fill methods, longhole stopes are filled with waste rock from development headings or from surface waste.

Some of the ore produced with the longhole drill machines is generated by drilling old pillars. Other stopes are blind by drilling uppers and blasting a slot at the far end of the stope to enable the ore to break in the subsequent larger stope blasts. Uppers are drilled to a 10-15m height on vein projections in rows across the width of the vein. The rows closest to the slot are blasted first. The stope is mucked clean, or at least sufficiently to allow the next blast. The ore is extracted using remote- controlled scoops.

16.4 | Mine equipment

The mine has its own fleet of scoops, trucks, and drills as summarized in Table 16-1. Ore is typically delivered to the surface by contactors via truck haulage up the ramps. The list of contractor equipment utilized inside the mine and on surface is listed in Table 16-2.

The remaining reserve life-of-mine plan is based on an approximate production rate of 1,000 tonnes per day of ore mined from underground. This plan is also based on $16.29/oz silver and $1195/oz gold, and additional parameters as shown in Table 15-1. Utilizing the planned production rates, the remaining reserves show an expected mine life of 1.1 years. Total development planned for 2016 is 6,511 meters with 5,020 of those meters in waste development and 1,491 meters in ore.

As stated previously in section 15.1.1, dilution is applied to Measured and Indicated resource blocks depending on the mining method chosen. For blocks to be exploited using conventional cut and fill methods, external dilution was applied in the amount of 15% at a grade of zero. For blocks to be exploited using long hole methods, external dilution was applied in the amount of 30% at a grade of zero. Internal dilution is also applied based on any blocks that fall inside the stope shape but are below cutoff. A mining recovery is also applied to converted resources and is estimated at 95%. The overall result of these factors resulted in an overall dilution factor of 21.0% for Bolañitos.

Run-of-mine ore is hauled by 20 tonne dumper trucks and discharge on a grizzly with opening 11”. Oversize rock (>11’) is broken by a backhoe hydraulic hammer. The undersize material falls in a feed bin and further crushed in a primary jaw crusher of size 24”x36”. After the primary crusher, the ore is held in two coarse ore bins each with a 450-t capacity. Figure 17-3 shows the primary crushing circuit.

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | Recovery Methods

Figure 17-3 View of the Primary Crusher Circuit (left); Crushed Ore Bins (right)

From the coarse ore bins the ore is conveyed to a 6’x16’ vibratory screen with openings 3/8”, the undersize product is conveyed to the fine ore bins. The oversize material is fed to a 4.25’ standard head Symons secondary cone crusher where the ore size is crushed down to 2”. The secondary crusher product is screened by a 5’x10’ vibratory screen with openings 3/8”. The screen undersize product is conveyed to fine ore bins and the oversize material is crushed by a tertiary cone crusher (Metso, HP200). Figure 17-4 shows the secondary crushing circuit.

Figure 17-4 Vibration Screen, Single 6’x16’Deck (left); Fine Crushing Circuit (right)

The fine crushed ore (approx. 80-85% of -3/8”) is stored in two ore bins. The storage capacity of the first fine ore bin is 250 tonnes and of the second ore bin is 500 tonnes of ore.

The grinding circuit consists of two ball mills: No. 1 is of size 9’6” x 14’ with a 600 HP motor, the No. 2 mill is of size 11’x18’7” with a 1000 HP motor. The mills are fed independently from respective ore bins. Figure 17-5 shows the two ball mills.

The grinding product is the cyclone overflow with 70-75% passing 74 microns and flows further to the flotation circuit. Each ball mill has a separate rougher and scavenger cell lines. The ball mill #1 line consists of four (4) flotation cells with capacity 500 ft3 each. The ball mill #2 line consists of nine (9) flotation cells with capacity 300 ft3 each. The rougher and scavenger concentrates from both lines are combined and fed to the column flotation cell.

The flotation layout considers two cleaning stages though the 2nd cleaning stage was shut down in December 2013 since the concentrate grade obtained in the column cell was meeting the target silver grade between 7 and 9 kg/t. Figure 17-6 shows the cleaner cells and flocculent mixing system.

Figure 17-6 1st Cleaner Cells (left); Flocculent Mixing System (right)

The final concentrate flows by gravity to a thickener, where it is thickened to 60% of solids, then it is pumped to a filter press where concentrate is dewatered down to 13-17% of moisture. The filtered concentrate is stored, then loaded on 35 t trucks and shipped to concentrate traders. Figure 17-7 shows the filter press and concentrate storage and shipment loading area.

Bolañitos Project | PROJECT INFRASTRUCTURE

18. | PROJECT INFRASTRUCTURE

EDR has all of the necessary mine and mill infrastructure to operate the Bolañitos Project efficiently and to comply with all regulatory standards imposed by the various government agencies.

18.1 | Mine Pumping

At the Bolañitos Project, only a limited amount of ground water is encountered, each mine contains a principal sump that sends the water to the surface. Underground settlers/sumps ensure that the water pumped to surface is largely free of solids. During development, further dewatering facilities are provided to pump any ground water and mine service water to the water treatment facility. Dewatering lines are advanced with the main ramp development.

18.2 | Mine Ventilation

At the Bolañitos mine, eight raise boreholes were developed to improve the ventilation during progressive periods of the mine development. Five of the raises were developed for the Bolañitos vein and the others were developed for the Lucero vein areas.

The principal mine ventilation for the Bolañitos vein areas is provided by a 70,000-cfm exhaust fan that was installed in borehole number one, with the fresh air drawn down the ramp and the other four boreholes of the area. At the Lucero, Daniela Sur and Daniela Norte ramps, 4 exhaust fans are installed in boreholes #8 (120k), #10 (80k), #12 (160k) and a conventional raise (80k), with the fresh air drawn in through the ramps. This system is providing the ventilation requirements which are based on the amount of diesel equipment running at any time, the system is an exhaust system).

Secondary ventilation is by conventional axial-vane mine fans that are from 24 to 42 inches in diameter and 20 to 150 hp. These fans are blowing fresh air into the working areas using ventilation tubing to deliver the necessary cfm.

Fresh air for the La Luz Mine is being provided through the access from the Los Angeles Shaft and enters the mine on 310 level where most of the air flows to the 220 level through a series of ramps and conventional raises.

On the 310 and 220 levels, the use of auxiliary electric ventilation fans is used to ventilate the stopes. The total air flow is exhausting to surface through the Asuncion Shaft.

18.3 | Mine Electrical

The electrical power for the mine is distributed by a series of substations connected to the public power grid. Electric power arrives at the mine sites via 13.2 kV overhead transmission lines. Table 18-1 summarizes the location and capacity of the transformers installed in the Bolañitos Project.

19. | MARKET STUDIES AND CONTRACTS

EDR has neither a hedging nor forward selling contract for any of its products. As of the date of issuing this report, the company has not conducted any market studies, as gold and silver are commodities widely traded in the world markets. Due to the size of the bullion market, which in 2014 saw a demand for silver of 1.07 billion ounces, EDR's activities will not influence silver prices (it produced 7.2 million ounces, or less than 1% of world demand).

EDR produces a silver concentrate which is then shipped for refining. The concentrate produced by EDR at its mines is refined by third parties before being sold. To a large extent, silver concentrate is sold at the spot price.

Table 19-1 summarizes the high and low average annual London PM gold and silver price per ounce from 2000 to 2016. For the purposes of this report the resources and reserves are stated at the 2-year average metal prices for silver and gold as of October, 1st 2016.

Over the period from 2000 to 2016, world silver and gold prices have increased significantly. This had a favorable impact on revenue from production of most of the world’s silver mines, including the Bolañitos Project. Between 2011 and 2016 there has been a significant reduction in the silver and gold prices, which has caused much stress for mining companies around the world.

20.4 | Considerations of Social and Community Impacts

Bolañitos considers nearby communities as important stakeholders and, as such, the company pays special attention to their problems and requests for support. A good neighbor and open-door policy characterizes the relations with the seven communities inside and around the area of operations. A company representative interacts with the local authorities frequently.

According to the population and housing census of 2010, the inhabitants in the surrounding communities include 2,711 people living in the 7 locations. Women are 53.0% of the population. Table 20-3 presents population by gender in the communities, and shows the relationship of Bolañitos with them, whether directly or indirectly. The relationship with a community is indirect whenever it has a direct relationship with another mining company. The communities of Mineral de la Luz, Llanos de Santa Ana, Sangre de Cristo, Mineral de Mexiamora, and Mineral de San Pedro Gilmo are located inside the area of current or future influence. Two other communities are included due to their proximity. Regardless of the indirect relationship with these two communities, Bolañitos considers that it has a shared commitment with them.

Bolañitos has a policy of social responsibility based on community development. The tactic used to achieve this strategic principle is focused on:

| • | Education and Employability: Promoting learning opportunities ranging from basic education to technical skills and supporting the creation and development of small business that provide an economic alternative to mining related jobs.
| • | Infrastructure: Supporting construction, improvement or rehabilitation of community facilities, such as the Church, the playgrounds, or the roads.
| • | Health: In partnership with government institutions, EDR promote several health campaigns in the communities such as dental, vaccines, nutrition, pet control, and others.
| • | Sports: Also in partnership with government institutions and NGOs, EDR supports summer camps for children and in the last two years has sponsored one of the main races that happen in Guanajuato.
| • | Environment: EDR runs different environmental campaigns in the communities, such as the recycling of electronics, the reuse of tires to rehabilitate recreational sites, reforestation initiatives, cleaning up campaigns, and others.
| • | Traditions and Culture: EDR supports throughout the year the different celebrations that happen in the community, such as the day of the miner, mother´s day, day of the death, children´s day, Christmas celebrations, and others.

In addition, EDR responds to ongoing requests from the community. A large majority of the requests are for discarded materials, but there are also some requests for in kind donations such as transportation of materials, transportation to events, gifts for community celebration (such as children´s day), food, and other assistance.

In order to carry out social responsibility actions, Bolañitos has an internal procedure intended to channel the demands of the local communities, to assess their needs, to prioritize them, and to evaluate donations to be made to improve quality of life. The company is interested in maintaining a social license to operate by working together with the communities, providing communication support in resolving problems, promoting good practices in social solidarity through a work plan with the localities, and aiming for sustainability in all its actions.

Bolañitos Project | INTERPRETATION AND CONCLUSIONS

25. | INTERPRETATION AND CONCLUSIONS

EDR’s Bolañitos Mines Project has an extensive mining history with well-known silver and gold bearing vein systems. Ongoing exploration has continued to demonstrate the potential for the discovery of additional resources at the project and within the district surrounding the mine. Outside of the currently known reserve/resource areas, the mineral exploration potential for the Bolañitos Project is considered to be very good. Parts of the known vein splays beyond the historically mined areas also represent good exploration targets for additional resource tonnage.

Since EDR took control of the Bolañitos Mines Project, new mining areas have enabled EDR to increase production by providing additional sources of mill feed. EDR’s operation management teams continue to search for improvements in efficiency, lowering costs and researching and applying low-cost mining techniques.

25.1 | December 31, 2016 Mineral Resource Estimate

The mineral resources for Bolañitos mine as of December 31, 2016, are summarized in Table 25-1. The resources are exclusive of the mineral reserves.

| 1. | Measured, Indicated and Inferred resource cut-off grades were 162 g/t silver equivalent at Bolañitos.
| 2. | Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources estimated will be converted into mineral reserves.
| 3. | Metallurgical recoveries were 79.6% silver and 84.5% gold.

For the year end 2016 there was an increase of 108,000 measured and indicated tonnes from the 2015 reported resources and a decrease of 141,800 inferred tonnes. The increase in measured and indicated tonnes is based on new exploration data and conversion of inferred resources to measured and indicate resources as the mine was developed during 2016.

25.2 | December 31, 2016 Mineral Reserve Estimate

The mineral reserves for the Bolañitos mine as of December 31, 2016, are summarized in Table 25-2. The reserves are exclusive of the mineral resources.

Table 25-2 Mineral Reserve Estimate, Effective Date December 31, 2016

| 3. | Mining Recoveries of 95% were applied.
| 4. | Minimum mining widths were 0.8 meters.
| 5. | Dilution factors averaged 21.0%. Dilution factors are calculated based on internal stope dilution calculations and external dilution factors of 15% for cut and fill and 30% for long hole.
| 6. | Silver equivalents are based on a 75:1 silver:gold ratio.
| 7. | Price assumptions are $16.29 per ounce for silver and $1,195 per ounce for gold.
| 8. | Mineral resources are estimated exclusive of and in addition to mineral reserves.
| 9. | Figures in table are rounded to reflect estimate precision; small differences generated by rounding are not material to estimates.

For the year end 2016 there was an increase of 17,300 tonnes from the 2015 reported reserves with a total of 372,058 tonnes reported as mined during 2016. The non-decrease in reserves is due to continued development in the La Luz and Plateros veins.

25.3 | Conclusions

The mine staff possess considerable experience and knowledge with regard to the nature of the orebodies in and around the Bolañitos property. Mine planning and operations need to continue to assure that the rate of waste development is sufficient to maintain the production rates included in the mine plan.

A major change in ore metallurgy during the life of the current reserves is very unlikely, as nearly all of the ore to be mined will come from veins with historic, recent, or current production.

Areas of uncertainty that may materially impact the mineral resources and reserves and subsequent mine life presented in this report include the following:

| • | Mining assumptions
| • | Dilution assumptions
| • | Exchange rates
| • | Changes in taxation or royalties
| • | Variations in commodity price
| • | Metallurgical recovery
| • | Processing assumptions

The QP considers the Bolañitos resource and reserve estimates presented here to conform with the requirements and guidelines set forth in Companion Policy 43-101CP and Form 43-101F1 (June 2011), and the mineral resources and reserves presented herein are classified according to Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards - For Mineral Resources and Mineral Reserves, prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council on May 10, 2014. These resources and reserves form the basis for EDR’s ongoing mining operations at the Bolañitos Mines Project.

| 125 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | INTERPRETATION AND CONCLUSIONS

The QP is unaware of any significant technical, legal, environmental or political considerations which would have an adverse effect on the extraction and processing of the resources and reserves located at the Bolañitos Mines Project. Mineral resources which have not been converted to mineral reserves, and do not demonstrate economic viability shall remain mineral resources. There is no certainty that all or any part of the mineral resources estimated will be converted into mineral reserves.

The QP considers that the mineral concessions in the Bolañitos mining district controlled by EDR continue to be highly prospective both along strike and down dip of the existing mineralization.

| 126 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | RECOMMENDATIONS

26. | RECOMMENDATIONS

Outside of the currently known reserve/resource areas, the mineral exploration potential for the Bolañitos mines are considered to be very good. Parts of the known vein splays beyond the historically mined areas also represent good exploration targets for additional resource tonnage. The concession areas contain many veins and the QP considers there to be reasonable potential of discovering new veins and splays besides those that are currently mapped.

An exploration budget has been developed for 2017 and discussed in the following section.

26.1 | Exploration Program

In 2017, EDR will conduct a surface drilling program in the Bolañitos South and Bolañitos North areas. Table 26-1 summarizes the planned 2017 exploration budget for the Bolañitos Mines Project

Table 26-1 Bolañitos 2017 Priority Exploration Targets

Project Area | 2017 Program
Meters | Budget US $
Bolañitos South & North | 6,000 | 900,000
Total | 6,000 | 900,000

26.2 | Geology, Block Modeling, Mineral Resources and Reserves

HRC recommends that the process of converting mineral resources into reserves from 2D polygons to 3D block models be continued. During the last couple of years, considerable progress has been made on this process with only nine veins remaining to be converted to 3D. Additional modeling efforts should be made to define the mineralized brecciated areas as they have been an important source of economic material encountered in the current operation, and could provide additional tonnage to support the mine plan.

EDR currently utilizes the exploration drilling and chip and muck samples in their resource and reserve calculations. HRC recommends that future efforts focus on constructing block models for resource and reserve reporting utilizing only the exploration and underground drilling results. The chip and muck samples should be used to develop the production model. This will help keep data densities consistent in each modeling effort and will provide another level in the reconciliation process to compare modeling results.

| 127 |

Endeavour Silver Corp. | NI 43-101 Technical Report
Bolañitos Project | RECOMMENDATIONS

Although the reconciliations conducted by EDR show good comparison between planned versus actual values, the reconciliation process should be improved to include the estimated tonnes and grade from the resource models. Because the LOM plan is compared to the plant production on a monthly basis, the actual physical location of the material mined may be different than the planned location. Due to the many stopes that are mined during a day this can only be completed on an average monthly basis due to blending of stope material into the mill. The monthly surveyed as mined areas should be created into triangulation solids and saved on a monthly basis for reporting the modeled tonnes for each month. The combination of the 3D block models and 2D and polygonal reserves makes this process difficult but considerable progress has been made during the last year to get all resources and reserves into 3D block models. The model-predicted results versus actual can then be used to determine if dilution factors need to be adjusted, or perhaps the resource modeling parameters may require adjustment if there are large variances. The mill production should be reconciled to the final concentrate shipments on a yearly basis, and resulting adjustment factors should be explained and reported.
