1.SUMMARY

 

Gustavson Associates, LLC (Gustavson) was commissioned by Rio Novo Gold Inc. (Rio Novo) to prepare a Canadian National Instrument 43-101 (NI 43-101) compliant Independent Technical Report (Technical Report) of the mineral resources of the Toldafria Prospect, Villamaria District, Department of Caldas, Colombia.

 

Core Values Mining & Exploration Company (“CVME”), a private company, acquired an option to purchase the Toldafria claim, title GEWM-12, currently owned by Nestor Jose Gutiérrez Gómez, on February 19, 2009. CVME subsequently optioned a portion of the Project to Universal Gold Mining Corporation (“Universal”) pursuant to an option agreement dated April 23, 2010, wherein Universal has the right to earn-in up to 50% interest in the Project (the “Option Agreement”). On April 8, 2011, Rio Novo Gold Inc. entered into binding Letter of Intent (“LOI”), subject to confirmatory due diligence, with CVME to acquire a 75% operating interest in the Toldafria Gold Project. On May 31, 2011, Rio Novo completed the acquisition of CVME’s 75% interest in the Toldafria Gold Project and also executed an agreement with Universal to acquire the remaining interest in the project, making Rio Novo the 100% owner of the Project. From 2009 to the present, CVME has carried out exploration of the Toldafria claim.

 

1.1History and Ownership

 

Gold mining in Colombia dates back to pre-colonial history. Gold mining was first performed by the native inhabitants of the northern Andes who were some of the region’s foremost goldsmiths. Placer and vein gold were mined by Colombian Indians mainly in the Cauca and Magdalena drainages with a surprising amount extracted from lodes in Buritica and in Antioquia.

 

When the Spaniards arrived they began searching for various precious metals fueled by tales of “El Dorado”. During the Spanish colonial times, gold was extracted from three main areas, the Cauca River drainage, the upper and middle Magdalena River drainage, and the Pacific coastal area. The northern Andes or New Granada as it was known, became Spain’s largest gold producer but ranked as Spain’s third largest mining area. This was due in part to Colombia lacking large silver deposits as were found in Mexico. At the end of the eighteenth century, Colombia provided Spain an average annual production of 18,000 Castilian marcos or 4,140,000 grams (West, 1952).

 

It is unknown when mining began at Toldafria. The earliest mention of mining at Toldafria is by Vicente Restrepo (1886) where he mentions “three leagues from Manizales is the large vein at Toldafria.” The Toldafria prospect is known to have been exploited by artisanal gold miners since at least the early 1900’s. Exploitation of the area began as placer mining in the Rio de California at the base of the prospect and later continued underground.

 

May 31, 20111 
Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

In his 1901 manuscript, Fortunato Pereira-Gamba documented artisanal gold mining in the Toldafria area. Ore was hand crushed and run through a stamp mill and the crushed fines were then panned for gold. Gamba reported a gold production at Toldafria of up to 22 ounces per day by artisanal methods. In the book Monographs of Rufino Gutierrez (1921), Gutierrez indicates that Toldafria gold production was approximately 20 pounds per month. The current property owners report gold production of 8 to 15 pounds per month. Today there are approximately six kilometers of tunnels, drifts, and crosscuts. (Gaitan, 2009).

 

Within the last 10 years there has been an increase in interest by foreign gold producers in historic artisanal mines in Colombia. Companies such as Colombian Goldfields (Marmato Prospect), Greystar (California, Santander and Anglo Gold Ashanti (Colosa Prospect, 10 MM oz) have begun developing mines within the Colombian Cordillera. Gustavson has not independently verified this resource estimate.

 

The Toldafria Project is a 164 hectare mining property. The Toldafria claim, Mining Title GEWM-12, is owned by Nestor Jose Gutiérrez Gómez (“the Permit Holder”).whose family has been working the claims for the last 40 years. The Permit Holder agreed to sell his interest in the Project to CVME pursuant to an agreement dated February 19, 2009. CVME subsequently optioned a portion of the Project to Universal Gold Mining Corporation (“Universal”) pursuant to an option agreement dated April 23, 2010, wherein Universal had the right to earn-in up to 50% interest in the Project (the “Option Agreement”). On April 8, 2011, Rio Novo Gold Inc. entered into binding Letter of Intent (“LOI”), subject to confirmatory due diligence, with CVME to acquire a 75% operating interest in the Toldafria Gold Project. As purchaser of the CVME interest, Rio Novo is bound by the February 19th Agreement and inherits US$750,000 in remaining payments to the Permit Holder. On May 31, 2011, Rio Novo completed the acquisition of CVME’s 75% interest in the Toldafria Gold Project and also executed an agreement with Universal to acquire the remaining interest in the project, making Rio Novo the 100% owner of the Project.

 

Rio Novo and the Permit Holder will work together to convert the existing 10 year license to a 30 year concession contract. The Project has an Environmental License for small-scale mining, which will have to be modified for a modern mine under the Colombian mining code process. Rio Novo intends to manage all such processes, conversion to concession contract, exploration permits, environmental approvals and mining consents & authorizations at the local level, establishing community relations, sustainability and institutional relations efforts as a priority in the development of the project.

 

Immediately to the northwest of the Toldafria claim (Title GEWM-12) are several tracts owned by the Arias Orozco Family. Anglo Gold Ashanti Colombia has been in possession of large tracts, titles EIG-164 and ICQ 080111X which surround both the Gutiérrez Gómez (Toldafria) and Arias Orozco tracts (Figure 1-1).

 

The mining permit is located on surface owned by the Hydroelectric Company of Caldas (CHEC) with whom the appropriate permits must be obtained.

 

May 31, 20112 
Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

CVME’s attorney, Dr. Hernando Escobar, performed a “Due Diligence” review of title GEWM-12 finding that it met normal standards. As mentioned, the permit holder is in the process of converting the current 10-year Mining Title to a Contract of Concession with a use of 30 years. The Mining Title has an approved Environmental Management Plan for small mining which will have to be modified to the exigencies and projections of Rio Novo.

 

The exploitation License No. 163-17 was extended in January 22, 2010 for 10 years, in accordance with Resolution No. 0144.

 

The environmental license will need to be expanded for the new operation. It will be necessary to plan Rio Novo’s full program of exploration-exploitation, including process plant type, metallurgical processes, impairment of natural resources, disposition of tails, etc.; and to submit an updated Environmental Management Plan, to the Environmental Authority when such work has been completed. There are on-going discussions with Corpo Caldas (the Caldas State Environmental Authority) to work out several environmental permitting issues.

 

Mr. William Crowl, a Qualified Person (QP) from Gustavson Associates has visited the CVME, Toldafria Prospect in January of 2010 and again in February of 2011. Mr. Crowl reviewed the mine site geology, sampling and sample splitting and storage procedures. In 2010, two samples were taken from existing channels within the La Ramada tunnel for verification, and one sample from the El Retiro workings. These samples were sent to ALS Minerals in Reno, NV for gold/silver fire assay. It is Gustavson’s opinion that the work performed thus far on the prospect meets industry standards.

 

The Toldafria prospect is located approximately 10 km southeast of the city of Manizales in the Villamaria municipality, Department of Caldas, Colombia. The city of Manizales has good infrastructure, services, and available workforce. Access to the Toldafria Prospect is by 5 km of paved road to Gallinazo where a four-wheel-drive accessible road is taken for another 5 km to the Toldafria trailhead. Access from the trailhead to the mine site office is by a heavily incised pack animal trail. Approximate transit time from the trailhead to the mine site is 1.5 hours. Currently all supplies and personnel are brought to the site via pack animal. Construction of a road to supply the camp is in progress.

 

CVME built an exploration base camp and secured sample storage facility at the site. Pre-existing structures include several old stamp mills. Power at the mine site is supplied by generator. There is currently no land line phone service at the site and cell phone reception is intermittent.

1.2Geology and Mineral Resources

 

The Toldafria deposit is situated within the north Andes Mountain Belt, known as the Colombian Central Cordillera. The style of mineralization is consistent with that of fracture filling stockwork in a low sulfidation, epithermal system in a host rock of Paleozoic schist.

 

Mineralized veins and veinlets are found to strike in two orientations. The first group of veins has a general strike and dip of N15°-30°E, dipping 22°SE and is concordant to foliation. The second, discordant group of veins has a general strike of N40°E, N-S, N50°W with dips of 65SE and 70SW. Discordant veins are typically between 2 – 4 cm and never exceed 12 cm in width.

 

From 2009 to early 2011, 2,041channel samples were taken by CVME in tunnels, 17 samples from outcrops and 11 from surface sediments. for a total of 2,069. Channel samples representative of 5m of tunnel were taken from crosscuts and drifts. Crosscut samples were taken from the rib, oriented across the foliation. Parallel drift samples were taken out of the back in a continuous zigzag pattern, from rib to rib.

 

May 31, 20114 
Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

An assay database of the channel samples, the outcrop samples and the sediment samples (totaling 1,664 samples) was created and loaded into MicroMODEL software. A kriged grade interpolation was performed with a search radius oriented with variography which mimics structure. With the sampling of adits above and below each other, a small part of the resource has been considered as Indicated and the balance of the mineral resources for this estimation were classified as Inferred. Table 1-1 shows the results of resource estimation.

1.3Conclusions and Recommendations

 

Observations made during Mr. Crowl’s site visits confirm the descriptions of the gold mineralization provided by CVME. Surface expressions of past gold mining activity are common, with abandoned and overgrown workings dotting the hills in the immediate area of the prospect. Inspections underground revealed very narrow steeply dipping, strike-persistent mineralized quartz veins and quartz-filled fractures exposed over considerable drift lengths. The horizontal spacing between these very narrow quartz veins was not consistent in the areas visited. It is important for CVME to establish the density of veining in the Toldafria area before further development decisions can be made. The concordant veins in the schist are far more sulfidic than the narrower vertical veins. The extent to which these veins are projectable for any appreciable distance will be directly related to the results of the proposed drilling program.

Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

CVME’s initial exploration program confirmed the significant presence of gold mineralization which has been mined on a small scale for more than a hundred years. Although the sampling was extensive in available underground workings, additional sampling such as core drilling will be needed to establish geological continuity of the 2 types of mineralization present. Given the mining history of the area with underground mines of much higher grade, and the close spacing of some of the known mineralized structures, it is reasonable to expect to expand this resource with further sampling using surface and/or subsurface core drilling, as well as, surface trenching.

 

The mineral resources estimated and reported herein are considered by Gustavson to meet the requirements of NI 43-101 for classification as indicated and inferred. Future efforts by Rio Novo to better define the mineral system at Toldafria will allow for a consideration of re-classification.

 

CVME has provided in depth exploration to define an inferred resource of 947,000 ounces of gold at a cutoff of 0.5g/t and a small indicated resource of 5,100 ounces. Gustavson recommends that an exploratory drilling program be implemented to further define the resource and provided geologic and geo-statistical support to better delineate vein systems. Further geologic investigations will be needed to ascertain an appropriate data density to establish geologic continuity of mineralization in 3 dimensions. Both surface and underground drilling is recommended.

 

CVME has proposed a Phase 2 exploration program of 10 core holes totaling 3000m. CVME has estimated a budget for the next year (Phase 2 cost of approximately US$944,000). Gustavson considers that the budget is adequate to accomplish the stated purpose of the program and to advance to the next decision point.

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

 

5.1Accessibility

 

The Toldafria Prospect can be accessed via paved road which that leads from the Enia District to Nevado del Ruiz. At approximately 5 km from the Enea District at location known as “Gallinazo”, the road becomes unpaved, accessible by four-wheel-drive vehicles only. The Toldafria trailhead is approximately 5 km from Gallinazo. The Toldafria Trail is a deeply incised trail accessible only to hikers and pack animals. It is approximately 1.5 hours travel time from the trailhead to the Toldafria Mine Camp.

 

5.2Local Resources and Infrastructure

 

The Toldafria Prospect is approximately 10 km from Manizales, a city of approximately 300,000 people and the Caldas Department capital. It is the commercial and agricultural center for the region and is in the heart of Colombia’s coffee producing area. Highways connect Manizales to other large cities such as Medellin and the capital city of Bogota.

 

In late 2010, and continuing into 2011, CVME has been pioneering a road to the Toldafria project site. There have been a number of challenges associated with the road building, including permitting stream crossings, cutting of trees and right-of-way negotiations. The high rainfall of 2010-2011 has resulted in slower than expected progress in completion of the road (Figure 4-3).

 

There is no electrical power a the mine site. Electricity is currently supplied by generator. Negotiations are being conducted with Hydroelectric Plant of Caldas to assess the viability of providing electrical power to the mine site. Approximately 4km of power line will have to be constructed.

 

5.3Physiography and Climate

 

The mine site ranges in elevation from 2800 to 3000 m above sea level. The topography is mountainous and abrupt. The area is marked by mass wasting features (creeps, slumps and slides) due to the large amount of rainfall. Average annual rainfall over a 30 year period is 149.5 cm per year. Monthly mean high temperature is relatively stable fluctuating from 23.7 to 25.0 degrees Celsius throughout the year (IDEAM, 2010).

6.HISTORY

 

Gold mining in Colombia dates back to pre-colonial period. Gold was first mined by the native inhabitants of the northern Andes who were also some of the regions foremost goldsmiths. Placer and vein gold were mined by Colombian Indians mainly in the Cauca and Magdalena drainages with ore extracted from lodes in Buritica and in Antioquia.

 

Tales of “El Dorado” prompted the Spaniards to search for precious metals. Gold was extracted during the Spanish colonial era from three main areas, the Cauca River drainage, the upper and middle Magdalena River drainage, and the Pacific coastal area. The northern Andes or New Granada, as it was known, became Spain’s largest gold producer but only Spain’s third largest mining area. Colombia lacked large silver deposits as were found in Mexico. At the end of the eighteenth century, Colombia provided Spain average annual production of 18,000 Castilian marcos or 4,140,000 grams (West, 1952).

 

The earliest mention of mining at Toldafria is by Vicente Restrepo (1886) where he mentions “ three leagues from Manizales is the large vein at Toldafria.” The Toldafria prospect has been exploited by artisanal gold miners since at least the early 1900’s, first as placer mining in the Rio de California at the base of the prospect and later underground. Today, there are approximately six kilometers of tunnels, drifts, and crosscuts.

 

Early artisanal gold mining at the Toldafria area was documented by mining engineer, Fortunato Pereira-Gamba. In his 1901 manuscript, MINERAL WEALTH OF THE REPUBLIC OF COLOMBIA (Harvard College Library) he mentions that the Manizales District has great potential for gold mineralization, describing the mineralization as consisting of extremely narrow (1 to 2 cm) persistent veins, and surprisingly rich. He describes the main veins as sub-horizontal veins crossed by vertical systems with some very rich and others sterile; and stockwork mineralization similar to “los Alemanes???”. The artisanal miners hand crushed the ore and ran it through a stamp mill. Crushed fines were panned for gold. Gamba reported gold production at Toldafria of up to 22 ounces per day using this method.

 

In the book Monographs of Rufino Gutierrez (Library Luis Angel Arango, Bogotá, Volume 1, National Press, 1921), the Toldafria mine is mentioned as one of the oldest mines with California mills and gold production of up to 20 pounds per month.

 

As recently as 1972, the Toldafria mining title was the property of Mr. Jose Gutiérrez Giraldo until his death. The property was passed down to his son, Nestor Jose Gutiérrez Gómez, the current title owner. Since 1972, gold ore has been mined and processed in five California stamp mills located on the site. Production for the period has been variable with reported monthly sales of 8 to 15 pounds (Néstor Gutiérrez, personal communication).

Within the last 10 years there has been an increase in interest by foreign gold producers in the historic artisanal mines in Colombia. Companies such as Medoro Resources (Marmato Prospect), Greystar (California, Santander) and Anglo Gold Ashanti (Colosa Prospect, 10 MM oz) are developing mines within the Colombian Cordillera. Gustavson has not independently verified this resource estimate.

 

6.1Previous studies

 

Lopez (1978), observed metamorphic rocks of the Cajamarca Complex and intermediate to acid composition subvolcanic stocks containing gold mineralization in veins and veinlets in the area between Manizales and Villamaria. He performed quantitative chemical determinations for gold, silver and copper followed by spectrographic analysis of the most representative samples. He concluded that the more valuable vein deposits of the region (gold, silver and antimony) are classified as epithermal, fracture filling or stockwork, related possibly to the intrusion of porphyritic bodies of dacitic to andesitic composition that were emplaced during the late Tertiary. He drew no conclusion about the quartz diorite body to the east of Manizales and the gold mineralization.

 

Pulido (1988), completed a geochemical study of a series of rock chips analyzed with atomic absorption and complete spectrography, concluding that the region of the California and Toldafria mines offered good potential for development of an exploration campaign and systematic sampling to delineate precious metal mineralization associated with stockworks with the possibility of developing a large mining operation.

 

In 1994, a gold resource mining development plan in the Department of Caldas was completed under an agreement of technical and financial cooperation between the Government of Caldas, Mineralco’s Office of Mining Affairs, and the University of Caldas with their senior Geology and Mines faculty. The plan concluded that the Toldafría mine hosts ten mineralized structures corresponding to tabular seams with centimeter thicknesses (1-5 cm) and one structural direction between N20°W and N20°E with subvertical dips. Mineralization was located in intense zones of fracturing. They defined the Toldafria deposit as an epithermal type based on the fracture filling and quartz druses. In hand samples, they found the mineralogic assemblages of pyrite, galena, and gold/silver in a silicious gangue.

 

According to Camacho, et al. (1999), a dike was found in the El Breque level of the Las Antiguas workings with an approximate thickness of 7 meters in contact with graphitic schist. Mineral associations in the dike indicate that it can be classified as a porphyritic basaltic andesite. The dike is saussuritized and contains pyrite. An east trending 1.5 km2 body of andesite porphyry was also identified.

Golden Amera INC. Resources, Grosso Group (2008), completed a reconnaissance report of mining titles of the Municipality of Villamaria between Toldafria, California and Maltería.. Within the excavated workings, 83 samples (47 country rock and 36 veins) were taken with a reported average grade of 0.27 ppm of Au for the country rock and 13.8 gr/tonne Au for the veins. The country rock samples were collected in continuous sections of 20 to 40 meters in length in the crosscuts of the La Antioquia, El Oriental, and La Divisa tunnels of the Toldafria Mine and the El Breque, Zanjón Hondo, and California tunnels of the California Mine. The vein samples comprised two to three pounds of vein material in distinct locations in the ribs of the tunnels.

7.GEOLOGICAL SETTING

 

CVME provided all geologic work and descriptions provided within this section with Spanish translation by Gustavson. This section is translated and paraphrased from reports written in Spanish by CVME.

 

7.1Regional Setting

 

The study area is located on the west flank of the Central Mountain range and is part of the Cauca - Romeral geologic zone (Lozano and Pulido, 1986). Paleozoic and Cretaceous aged igneous and metamorphic rock units outcrop within this zone.

 

7.1.1Cajamarca Complex

 

The metamorphic Cajamarca Complex forms the nucleus of the Central Mountain range in a N - S strip, made up of four general lithologic groups. (Gonza'les, 1993):

 

·Pelitic group: Sericitic schist, feldspathic gneiss and low metamorphic rank rocks;

 

·Quartzose group: Quartzites;

 

·Calcareous group: Marbles

 

·Basic group: amphibolites, greenschists.

 

 

These Paleozoic (Cambrian to Ordovician) rocks were weakly, regionally metamorphosed by Mesozoic (Ibagué batholith) and later intrusions of hypo-abyssal bodies of intermediate to dacitic porphyry composition. These intrusions are expressed as an andesitic porphyry body extending NNW and outcropping east of the Toldafria prospect, and in the Gallinazo stock, located to 5 km to the north of the area. Dikes and apophyses of these bodies are common.

 

Structurally, the rocks of the Cajamarca Complex display a N-S regional strike concordant with the Andean regional trend, with slight variations especially in the Eastern flank, where it has been disturbed (González and Nuñez, 1991). The dominant N-S trend prevails on the Western flank.

 

The Cajamarca Complex rocks form the host for the precious metal mineralization, related to the Mesozoic and Cenozoic intrusions. The mineralization is manifested by a great number of enriched quartz/sulfide seams, gold and silver, occasionally concordant with the strike and dip of the foliation or in zones weakness and jointing, generating stockworks and filled fissures.

 

7.1.2Manizales Stock

 

The Manizales stock, located east of Manizales on the western flank of the Central Mountain range, is predominantly tonalitic and oval-shaped, parallel to the axis of the mountain range (González, 1993) Most of this unit is covered by younger pyroclastic rocks from recent volcanic activity in the area, intruding the metamorphic rocks of the Cajamarca Complex.

 

May 31, 201117 
Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

The tonalitic to granodioritic stock is predominantly phaneritic to equigranular with intermediate quartz, plagioclase, potassium feldspar and biotite as the main minerals, and apatite, zircon, sphene, alunite as opaque accessories (González, (1995) in González and Jaramillo (2002).

 

According to Jaramillo (1978), age determinations by fission tracks method yielded ages of 62.4. ± 3.6 m.a in zircon and 10.5 ± 1.0 m.a in apatite. The latter age in apatite age indicates time passed after the rock had cooled below 100°C. The zircon age agrees generally with the K/Ar in biotite age of 57 ± 2 m.a. reported by McCourt et al. (1984).

 

7.1.3Pyroclastic Flow Deposits

 

These deposits correspond to volcanic mud flows modified byre-deposition of volcanic material, especially of ash-gray, sands, lapilli and fragments of volcanic rocks of pyroclastic origin.. This cycle began between the Pleistocene and Holocene (Herd (1974) in González and Jaramillo (2002), Thouret (1984) in González (1995)).

 

7.1.4Pyroclastic Deposits

 

Local pyroclastic deposits are made up of pumice fragments of dacitic composition, as well as, porphyritic andesite fragments, forming interbedded ash layers with piedmont deposits, as at Enea and Maltería. The age for these deposits corresponds to the Pleistocene - Holocene interval and represents vestiges of the quaternary volcanic activity in the volcanic complex Cerro Bravo - Ruiz - Tolima. (Naranjo and Rivers, 1989).

7.2Tectonic Framework

 

The regional area is affected tectonically by the Romeral and Palestina system of faults and satellite faults to the regional system especially the WNW – ESE Villamaría-Termales fault, described by Thouret, (1985) and Naranjo and Rivers, (1989). They appear as an extensional strike-slip fault associated with a series of volcanic intrusions and domes, like the Sancancio, Tesorito, Gallinazo, Amazon and Lusitania domes, all aligned along the strike of the fault. This tectonic framework controlled the Toldafría mineralized structures and the associated minor faulting, the principal joint directions and intrusions of hypabyssal bodies as are present in the area.

 

7.3Local Geology

 

The 164 Ha Toldafria prospect is made up of hypabyssal metamorphic and igneous lithologies with a volcanic and sedimentary cover. Tectonically, the region is dominated by a series of associated structural lineaments (shear zones), overprinting the rocks with a cataclastic texture that localizes the veins and veinlets of the gold mineralization.

 

7.3.1Metamorphic Rock Unit (Pzc)

 

The Metamorphic Rock Unit (Pzc) makes up 83% of the local lithologies., typically as an interfingered sericitic quartz carbonaceous schist package complexly and sporadically interbedded with occurrences of actinolite hornblende schists and quartzites belonging to the Cajamarca Complex rocks.

 

The main macrocospic characteristics of this unit are: penetrative foliation defining a schistose texture, fine grain size, a silky feel, representing tonalities that are gray on fresh surfaces and brown on the weathered surfaces.

 

The rock has a mineralogical composition of quartz (30%-40%), plagioclase (10-15%), graphite (10-12%), sericite (10%-20%), chlorite (5-10%) and opaques (5-8%).

 

Structurally, the foliation displays a general tendency N30°E dipping SE, ranging from a strike of N-S dipping E and N10°W dipping SW, although due to tectonic effects micro-folding is recurrent.

 

Massive pyritization is commonly observed with the appearance of lenses and milky quartz veinlets concordant with the foliation where, and cavities and open spaces filled with iron oxides, whose thicknesses range between 0.1 cm and 20 cm. Discordant with the foliation, striking N-S, are vertical to subvertical mineralized structures filled with massive sulfide mineralization.

 

Toward the East of the area, this unit is intruded by hypabyssal igneous rocks, overlain by a volcano-sedimentary sequence. The main outcrops are observed toward the South and Southeast of the prospect area, on the right flank of the Quebrada Tolda Fría. Small outcrops are noted- towards the Southwestern sector in the Zanjón de los Pájaros and the tributaries of the Quebrada Chupaderos , as well as throughout the pack animal road that leads towards the Toldafria Mine.

Toldafria ProjectNI 43-101 Technical Report

7.3.2Hypabyssal Igneous Rocks (Tpad)

 

The hypabyssal igneous rocks (Tpad) make up 15% of the lithologies in the area, appearing as an elongated body extended in a N-S direction. Within the area, it is common to find dikes of the same composition measuring 8 m thick cutting the metamorphic sequence.

 

The Tpad macrocospically appears as a massive rock,- dark gray when fresh and brown to cream when weathered. Phenocrysts vary from euhedral to subhedral, made up of plagioclase (30%) (defining the porphyritic texture), biotite (20%), hornblende (25%), quartz (5%-10%) and iron oxides (0,5%-1%), classified as an Andesite porphyry. Mineralization of this body has not been identified in the field, but mineralization has been observed in the adjacent California mine immediately to the East, in the El Breque tunnel, appearing as a dike 8 m thick of the same composition, intensely mineralized with sulfides of lead copper and iron.

 

The main outcrops of this unit are located in the northeast region, east and south-east of the prospect on the Quebradas Toldafria and Zanjon de los Pajaros, as in the central and upper divide of the Quebrada California and Quebrada Toldafria This unit correlates with the porphyritic bodies of andesitic-dacitic composition of the Neogene reported by Herd (1974).

 

At Toldafria, mineralization in the andesitic porphyry has not been observed. However, in the Gallinazo sector, 5 km to the North of Toldafria, the porphyritic textured Gallinazo stock is intensely hydrothermically altered (silicified and argillized), with veinlets of quartz and abundant fractures mineralized with pyrite (2-3% in volume),containing scattered very fine free gold, in free state, electrum (alloyed with silver) and, possibly, gold combined with the pyrite. There are also occurrences of sphalerite, chalcopyrite, possibly soft arsenopyrite and galena.

 

Pulido (1988) speculates that the Gallinazo and similar mineralization in the area are “hotspring” type deposits, and are intimately related to the Cenozoic dacitic stock. In the past, the Gallinazo mine was open-cast mined using monitors in the oxidized and hydrothermally altered zones. At present the Gallinazo mine is abandoned.

 

7.3.3Recent (Holocene?) Alluvial and Pyroclastic Fall Deposits (Qal)

 

The Recent pyroclastic volcanic ash fall deposits are moderately consolidated, interbedded layers of fine ash and layers of lapilli with pumice, and are moderately altered to argillaceous-sandy soils varying from cream to dark coffee color.. The maximum thicknesses are located towards the higher portions of shallow slopes, where they cover the totality of the local lithologies.

 

May 31, 201121 
Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

The alluvial deposits are related to fluvio-torrential flows that generate terraces in the broken margins of the Quebrada Zanjon de los Pajaros and Quebrada Toldafria, the conforming material is represented by matrix supported sub-angular to sub-rounded igneous and metamorphic gravel whose sizes fluctuate between gravel and boulders up to 2 meters in diameter, in a matrix that varies from sandy-mud to clayey-mud.

8.DEPOSIT TYPES

 

The Toldafria Deposit has been characterized as a low sulfidation epithermal model (Gaitan, 2009). This type of deposit forms at relatively shallow depths, usually within 1 to 2 km of the surface, at a temperature range of less than 150°C to 300°C.

 

Low sulfidation systems exhibit a wide variety of textures including banded, crustiform quartz/chalcedony veins, and druse quartz cavities. Vein breccias may occur due to multi-episodic deposition accompanied by hydraulic fracturing followed by explosive pressure release. Bladed calcite also may occur as a result of boiling. Silica sinters may be deposited at the original surface, but are often absent due to erosion (White and Hedequist,1990).

 

The defining characteristic of a low sulfidation system is the near neutral pH of the postulated mineralizing fluids, a result of the mineralizing fluid reaching pH equilibrium with the host rock. Generally this type deposit displays quartz vein mineralization, stockworks and breccias with gold, silver, pyrite, with smaller and variable amounts of galena, chalcopyrite, sphalerite, sometimes with tetrahedrite and sulfosalts in the upper levels or near the original surface (White and Hedenquist, 1990). In the case of Toldafria, the mineralization normally exhibits open space textures, typical of hydrothermal systems associated with volcanism(Gaitan, 2009).

 

The mineralized zones typically are located in structures, but can occur within permeable lithologies. The ore zones are centered in structurally controlled, hydrothermal conduits that typically tend to open upwards.

 

Sillitoe (1993) indicates that in epithermal deposits, large (> 1 m width and hundreds of meters in length) or small veins and stockworks are common with less prominent disseminations and replacements. The vein systems can be laterally extensive, nevertheless their vertical extension can relatively be restricted. The zones of high grade are commonly in zones of fault dilation, in flexures and ramifications.

9.MINERALIZATION

 

Individual veins within the Toldafria prospect are generally narrower than 1 meter, high grade and frequently in groups or vein systems. The mineralization also can be disseminated within the host rock and/or associated hydrothermal or tectonic breccias.

 

Within the study area, (1) subvertical veins with a N-S strike and slight variations to the east and west, and (2) low angle parallel veins concordant with the schist foliation silicic lenses, intrude the host rock.

 

Structurally the Toldafria mineralization is fissure-filling associated with a system of joints related to extensional movement along the Romeral - Palestine system of faults.

 

9.1Mineralized Zones

 

The Toldafria mineralization is composed of pyrite, electrum, gold, silver, acanthite, chalcopyrite, sphalerite, galena, tetrahedrite, sulfosalts of silver and/or selenides. White and Hedenquist (1990) state that deposits like Toldafria are commonly zoned vertically in 250 to 350 m, being rich in Au-Ag and poor in base metals at the top, grading downwards to a zone richer in silver and base metals and finally at depth predominating in base metals. From surface to depth, the metal zonation goes from Au-Ag-As-Sb-Hg, to Au-Ag-Pb-Zn-Cu, and finally Ag-Pb-Zn. In alkaline rocks, tellurides, vanadium mica (roscoelite) and fluorite can be abundant, with smaller amounts of molybdenite.

 

9.1.1Concordant Veins or Veinlets

 

The Toldafria concordant veins occur parallel to the foliation of the host rock, generally striking N15°-30°E and dipping 22°SE fluctuating between 1 and 28 cm in thickness. Macroscopically, sulfides observed are pyrite, marcasite, chalcopyrite, galena, with sulfosalts like tetrahedrite and iron oxides/hydroxides. The sulfide mineralogy is associated with milky quartz and quartz with drusiform texture. Propyllitic (epidote-chlorite) alteration, argillic (kaolin) alteration and silicification are common (Figure 9-1 & 9-3). Also common are pores or interconnected cavities of siliceous material, referred to as “vuggy silica”.

 

9.1.2Discordant Veins or Veinlets

 

Crossing the foliation of the host rock, the discordant veins and veinlets strike from N40°E, to N-S, and N50°W, with dips of 65°SE to 70°SW, becoming vertical to subvertical. The steep dip of the veins facilitates the development of certain mining methods. The thicknesses of the discordant veins do not exceed 12 cm and in general average between 2-4 cm in thickness.

 

The sulfide mineralogy of the discordant veins and veinlets is comprised of pyrite, chalcopyrite, bornite, sphalerite, pyrhotite, galena, tetrahedrite, iron oxides and milky quartz, with strong phyllic and argíllic alteration and subordinate propylitic alteration (Figure 9-2).

This type of discordant vein manifestation is in the totality of the tunnels explored, on the different drifts developed in the mining works, being of greater thickness (12 cm) located in the tunnel El Antioquia ; from each one of the tunnels samples were taken whose maximum value is of 69.16 g/t (La Mirada).

9.2Gangue Mineralogy

 

The gangue mineralogy in the prospect area is quartz, chlorite, hematite, calcite, sericite and kaolin.

 

9.3Alteration Mineralogy

 

The three main alteration assemblages at Toldafria are argillic alteration with kaolinite and sericite; propylitic alteration with an associated chlorite – epidote; and silicification with multiple generations of quartz associated with veins. The veins are bounded in many cases by a sericíte – kaolinite assemblage.

10.EXPLORATION

 

The Toldafria prospect has been historically mined for at least the last 100 years. A number of pre-existing tunnels on the site provided CVME personnel access for mapping and sampling underground. Tunnels typically begin with a crosscut into the hillside, with multiple drifts branching off of the main portal crosscut.

 

10.1CVME Exploration Program

 

During CVME’s Toldafria exploration program, 28 tunnels were identified in a roughly 500m x 500m area, of which only two remain in production (La Oriental and La Antioquia). Additional workings and signs of previous mining activities extend well beyond this initial focus area, but have received no attention to date by CVME. As part of the exploration program, CVME performed the following:

 

·Compilation and analysis of existing bibliographical material on the Toldafria study area.

 

·The aerial photographic flight lines (206-207-208 C-2117 of the IGAC) were analyzed and interpreted. Structural elements, including faults, lineaments and lithologic contacts were determined using geomorphology.

 

·Geologic mapping of existing mine workings to include vein widths, vein orientation, vein density, mineralogy, and alteration.

 

·From 2009 to early 2011, a total of 2,069 samples were taken, 2,041 from channel sampling of multiple underground mines (workings) within the target area, 17 outcrop samples and 11 surface sediment samples (Figures 9-3 to 9-10 and 12-1).

Toldafria ProjectNI 43-101 Technical Report

As at the end of January, 2011, the assay database which eventually was used for the mineral resource estimate contained a total of 1,664 samples, of which 1,636 were channel samples from the underground workings, 11 were sediment samples and 17 were outcrop samples. Sample locations and assays are listed in Appendix A. Figures 9-5 and 9-8 show the locations of the vein and host rock (crosscut) samples.

 

Crosscut samples, denoted with an X, were taken as continuous channels across the rib, along 5 m of tunnel perpendicular to foliation. Channel samples from parallel drifts along potentially mineralized veins, veinlets and silicified zones, denoted with a P, were taken out of the back in continuous zigzag channels along 5 m of tunnel. Channel samples in both crosscuts and parallel drift are a composite of any veins intersected and host rock. The channel sample surfaces were cleaned and then cut with dimensions of 5 cm by 10 cm in section.

 

12.2Sampling Methodology

 

Each channel sample contained approximately 6o kg of material and was homogenized and split into 2 parts. The first split was packed, labeled and stored as reject in the sample warehouse. The second portion was split to obtain a 2kg sample (requiring 5 to 6 splits depending on the exact original quantity).

 

The sample was suitably packed in a polyethylene bag and labeled with a consecutive number, sent to a laboratory for analysis of gold and silver by fire assay. The balance of the sample was stored as a duplicate in the sample preparation storage area.

 

Rib samples were taken in crosscuts between vein structures. These samples were 10cm x 5cm x 5m in length. They were taken perpendicular to foliation to adequately represent the cross section of the country rock (graphitic schist).

13.SAMPLE PREPARATION, ANALYSES AND SECURITY

 

13.1Sample Preparation

 

Throughout the sampling process, the samples were monitored by the exploration team headed by an exploration geologist. Field assistants were supervised as to sampling methodology and during sample collection. Approximately 60 kg of sample was removed from each channel. Bulk channel samples were transported directly to the mine camp storage facility where they were inventoried, crushed and split.

 

All samples were hand crushed. Splitting was performed using a riffle splitter. One split was placed in storage in a secured warehouse for future testing. The other split was further reduced using a riffle splitter to obtain a 1 kg sample for laboratory testing.

 

13.2Sample Analysis

 

Samples received by SGS laboratory were dried and crushed. Samples were then tested using fire assay methods with either atomic absorption or gravimetric finish. Detection limits and descriptions of the assays are listed in the following table.

 

Table 13-1 Assay Descriptions

 

Assay code Description Detection Limits
FAA313 Fire Assay with AA finish 5 to 5000 ppb
FAG303 Fire assay with gravimetric finish unknown
ICM40B Multi element analysis (50 element) Variable

 

13.3Sample Security

 

The 1 kg samples split at the CVME mine site were transported to the CVME Colombia office in the city of Manizales. Chain of custody was maintained throughout this process through delivery records and verification of shipments. CVME cataloged all samples prior to shipment to SGS laboratory in the Municipality of La Estrella, Department of Antioquia. Lab samples were delivered directly to SGS authorized personnel.

 

All initial sample splits stored at the CVME camp were placed in a secure locked storage facility for future testing. The storage facility is enclosed within a locked chain link fence (Figure 13-1). There is no full time human security at the site.

14.DATA VERIFICATION

 

William Crowl, a qualified person as defined in NI 43-101, traveled to the CVME office and Toldafria mine site in Manizales, Colombia during the week of January 25, 2010 and again during the week of February 7, 2011. During the site visit to the CVME Toldafria prospect, data checks were made on channel samples, assays, geologic logs and maps.

 

14.1Verification of the Quality Control Program

 

Sample quality control was performed by SGS Colombia S.A. Minerals Service. Sample quality assurance/quality control procedures for geochemical testing are listed in Table 13-1.

 

Table 14-1 SGS Laboratory Quality Control

 

Controls Frequency

Greater than 25 samples, minimum one control every 25 samples

 

Blanks Two blanks inserted for each batch of samples (maximum 98 samples per batch)

 

In order to verify the sampling and testing program, three additional confirmation channel samples were taken by Mr. Crowl in La Ramada tunnel and El Retiro Tunnel. Samples were transported by Mr. Crowl to the United States and sent via courier to ALS Minerals laboratory in Reno Nevada for fire assay testing. Confirmation samples were dried and crushed to 70% less than 2mm. Samples were split using a riffle splitter and pulverized to 85% of sample less than 75 μm. Samples were tested using fire assay with either gravity atomic absorption finish. Results of confirmation fire assay testing are shown in table 14-2.

14.22010 QA/QC Program

 

CVME and SGS performed further QA/QC analyses in 2010. Analysis of Standards indicated no problems for the 0.53ppm and 2.5ppm standards. One sample in the 10.7ppm standard was between 2 and 3 standard deviations out of 16 samples. An analysis of the blanks used in 2010 indicated no problems.

 

May 31, 201146 
Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

For coarse crush duplicates, 54% of 24 samples required re-analysis, indicating that Toldafria has some coarse gold issues. Finally, in an analysis of the Field Prep duplicates, 90% of the samples showed differences greater than 20% of the original value, again an apparent result of coarse grained free gold in the samples. The graphs in the report are somewhat mis-leading, and further analysis of the results may be warranted. The report documenting the 2010 QA/QC program is included here in Appendix B.

 

Gustavson believes that the average grades within the domains are reasonable and the quantity of high grade samples shown in the sample statistics in Section 17 do not demonstrate that the distribution is highly skewed by the coarse gold. It may be prudent to analyze the use of larger samples in future exploration work, especially during core drilling.

15.ADJACENT PROPERTIES

 

While Colombia has a long history of gold mining, the country has seen very little foreign investment due to political instability. Recently, however, as political conditions in Colombia have improved, foreign mining companies have begun moving into Colombia. The information on the adjacent properties was sourced from industry publications and Gustavson has not independently verified the data.

 

15.1La Coqueta

 

The La Coqueta gold mine is located in an extension of the structural zone hosting Toldafria several km east of Manizales and 9 km north of Toldafria. It is a low sulphidation epithermal deposit similar to Toldafria. Mining is performed in an artisanal manner in the very narrow veins, crushing the ore in a stamp mill, followed by tabling and concentrating the fines to recover gold. For the last few months, La Coqueta has produced several tonnes of ore per day, from which 3 to 9 pounds of gold have been recovered each week.

 

15.2La Colosa (Anglo Ashanti Colombia)

 

The La Colosa deposit under development by Anglo Ashanti Colombia (located about 60 km due south from Toldafria) is classified as a porphyry gold deposit located near the town of Cajamarca, Department of Tolima. The mineralization is projected to extend over an area along strike in excess of 1500m in length and 600 meters in width. In 2008, Anglo Gold estimated an inferred resource of 9.7 Moz above a cutoff grade of 0.5 g/t with an average grade of 1.03 g/t (AngloGold Ashanti, 2008). It appears to be on structural strike with Toldafria.

 

15.3Marmato (Colombia Goldfields)

 

The Marmato project (located 60 km north from Toldafria) is an epithermal intermediate sulphidation type gold deposit located approximately 67 km north by northwest of the Toldafria prospect. It lies along a major suture, a possible paleo-subduction zone, which separates the Western and Central cordillera (Rodriguez and Warden, 1993). Goldfields estimates that there is an inferred resource of 2,553,000 oz gold at 1.05 grams per tonne. (Lewis and SanMartin, 2008).

16.MINERAL PROCESSING AND METALLURGICAL TESTING

 

16.1Mineral Processing

 

Historic mineral processing has been on an artisanal level. Extracted ore was either hand crushed or mechanically crushed in one of the five stamp mills in the prospect area. Gold was concentrated and recovered by panning down the crushed fines. Recent production using this type of gold gravity recovery method ranges from 8 to 15 pounds of gold per month as reported by the current title owner.

 

16.2Metallurgical Testing

 

16.2.1Resource Development Inc.

 

RDi (Resource Development Inc.) received one 10-kilogram composite sample to initiate the scoping metallurgical study for the Toldafria project. The sample was stage crushed to 6 mesh and split into 1 kg charges. One of the 1 kg charge was pulverized to P100 of 150 mesh, thoroughly blended and two representative samples of 75 grams split out for head analyses using one-assay-ton fire assay procedure. Duplicate assay was run on one of the splits. The head assays, given in Table 16-1, indicate that gold may be free because the assays varied from one split to the other. However, silver appears to be consistent from one split to the next.

 

Table 16-1  Head Assays for the Composite Sample
Element Assay, g/t
Assay # 1 Assay # 2 Assay # 3 Average
Au 8.676 8.745 14.712 10.711
Ag 19.60 20.00 20.80 20.13

 

Three 1-kg samples were stage-ground to P100 of 48 mesh, 65 mesh and 100 mesh and subjected to gravity concentration. The process flow sheet is given in Figure 16-1. The slurry was fed to a 3.5 inch diameter model KC-MD3 Knelson Concentrator and two products collected, namely gravity concentrate and gravity tailing. The tailings were filtered, dried and assayed for gold and silver. The concentrate was processed over a model 60 Gemini Concentration Table and two products were collected. The Gemini concentrate and tailings were dried and assayed for gold and silver.

 

The test results are summarized in Table 16-2. The test results indicate that gold is free milling and can be recovered by gravity concentration at a relatively coarse grind of P100 of 48 mesh. Gemini concentrate recovered 81.6% of the gold and 37.9% of silver. The concentrate assayed 3401 g/t Au and 2454 g/t Ag. As the ore was ground finer, the precious metal losses in the Knelson tailing increased. CVME has initiated a more detailed metallurgical study with twenty different samples from the deposit.

16.2.2Met-Solve Laboratories Inc.

 

RDi sent 17 metallurgical samples to Met-Solve Laboratories Inc., located in Langley, British Columbia, Canada on August 13, 2010 for further test work. The seventeen samples were combined to produce a single composite for testing.

 

An initial Falcon L40 test was done to test for centrifugal gravity recovery of gold. After promising results from the baseline gravity test, a program consisting of flotation and cyanidation system was added to evaluate the impact of these on the gravity concentrates and tails. Screen analyses were also done to determine particle size and gold distribution by size fraction.

 

The initial Falcon gravity test was done as per the flowsheet shown in Figure 16-2 and the gravity-float-leach procedure was done as shown in Figure 16-3.

Gravity alone recovered an 83 to 87% of the gold. Floating the gravity tails raised the gold recovery to 93% with float tails assaying 0.22g/t. The gravity tails (i.e. float feed) was calculated at 0.50g/t.

 

Met-Solve drew the following conclusions from their work. Gravity alone recovered between 83 and 87% of the gold. Flotation of the gravity tails raised gold recovery to a 93%. When cyanidation is included, the gold recovery was found to be 86% as a result of incomplete leaching of the gold.

 

The high sulfur content of the pan tails and float products likely contributed to the high cyanide consumption.

 

Gustavson’s review of the RDi and Met-Solve test work indicates that the gold mineralization at Toldafria is probably amenable to common extraction techniques employed in the gold mining business, worldwide.

17.MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

 

Gustavson has estimated a mineral resource for the known portions of the Toldafria deposit, using a three-dimensional block model and inverse distance estimate of the channel sample gold assays.

 

17.1Resource Estimation

 

Gustavson was provided with channel samples data taken in 14 tunnels on the title property. This information was combined in an importable csv file for import into MicroMODEL™ mine modeling software. Information included in the import file included:

 

·Sample number

 

·Location UTM

 

·Gold assay (ppb)

 

·Channel sample length

 

·Tunnel Name

 

In 2009, a total of 755 channel samples were taken in underground workings with an additional 17 outcrop samples from the property. In 2010, a total of 1,201 samples were taken and in early 2011, an additional 96 were collected. Samples used in the estimate are listed in Appendix A, totaling 1,664 samples including 17 outcrop and 11 surface sediment samples. Figure 17.1 shows location of underground channel samples used in the estimate, as well as surface samples.

 

17.2Assay Database

 

Gustavson was provided an updated database and sample maps for the Toldafria project. Tables 12-1, 12-2 and 12-3 show the breakdown of samples by tunnel. In addition, surface samples were included where they were located in juxtaposition and above the mine tunnels. The resource estimation database contains a total of 1,664 samples that were used. A sample assay cutoff date in January, 2011 was used to freeze the database. Stream sediment samples were taken which were not included in the resource estimate database.

 

May 31, 201155 
Rio Novo Gold Inc. 
Toldafria ProjectNI 43-101 Technical Report

Channel sample assays were divided into parallel (P) and crosscut (X) samples with special parallel and special crosscut samples taken directly within select veins. All P and X channel samples were collected such that they are representative of 5 meters of tunnel. Special samples were taken with varying lengths ranging from 0.2 to 2.7 meters. Assays were performed for gold and reported in ppb.

 

All 2010 assay data provided by CVME by late January 2011 were added to a database organized into a comma separated value format for import into MicroMODEL™ mine modeling software. Data included both fire assay for gold using gravimetric finish for higher grades and atomic absorption finish for lower grades. Gold fire assays from both methods were combined into one assay field for modeling purposes. Channel sample data were displayed using MICL’s Downhole Explorer program. The general orientation of the mine workings observed in Downhole Explorer was N75°E and N15°W.

 

Figure 17-1 shows the samples used for this study.

17.3General Statistics

 

General statistical analyses were performed on the assay data base for parallel, cross cut, and special samples (Table 17-1 and Figure17-2). The sample statistics cover a database of 1,636 samples, with 28 additional samples added but not statistically analyzed before the database was closed so that resource estimation could proceed. Gustavson considers that the database statistics would have varied little with the addition of these few samples.

17.4Modeling

 

At this stage of exploration no geologic model or grade shell model has been constructed for the prospect. Further systematic sampling from trenches and drill holes will permit this type of modeling in the future. Modeling utilized only channel sample assays from the various tunnels.

 

17.4.1Variography

 

Semivariograms, often noted simply as variograms, measure the spatial continuity between data points. Variograms for most gold deposits are complex and sometimes difficult to interpret, and exhibit even less structure when there are few samples available for the calculations.

 

Variography was performed on the P and X wall rock channel samples only. As individual sample groups, special parallel, special crosscut and surface samples did not have enough data for variography and were not considered representative of the rock mass.

 

While special samples could have been included with their respective sample set, the special samples and surface samples were omitted from variography and also from subsequent grade estimation. The special samples and surface samples represent relatively small volumes of rock at the sample points. They are indicative of the precious metal content of very specific mineral occurrences and are valuable as indicators only. Based on the vein density of the stockwork from maps provided by CVME, it is unlikely, at this stage, that individual veins can be modeled with a reasonable geostatistical basis.

 

The relatively high nugget effect seen in the variograms probably results from both the lack of geological control of the modeling, and the erratic nature of coarse free gold in the samples.

 

With additional sampling since the previous study, strong differences can be seen between the P and X samples. Though both still exhibit high nuggets, which is expected due to the nature of the high grade veins, and the effects of the coarse gold on the assaying. With the additional drifts that were sampled, there are now at least some samples vertically offset from each other and the rudiments of vertical variograms can be examined.

 

The X samples exhibit a more isotropic behavior with a slightly shorter vertical anisotropy. This correlates well with lower grade host rock with low angle foliations.

 

The P variography shows a strong N-S anisotropy of approximately 3:1, shown in the variogram rose below. Due to the smoothing effects of the width of variogram windows in very narrow structures, this may be understated. Estimation parameters

 

Because little or no sample support was available between mine levels and it is unclear how much material has been mined out, a conservative 20 meter isotropic search was used for grade estimation. Directional variograms are shown in Figure 17-3 and 17-4. Parameters of the variogram models for the P and X samples are given in Table 17-2.

17.4.2Block Model

 

Gustavson developed a block model of the title property with block dimensions as shown in Table 17-3. An overall model size of 700 x 650 x 300 meters with a block size of 5 x 5 x 5 meters was constructed for estimation.

Maximum 849,600 1,039,550 3,150
No. of Blocks 140 130 60

 

17.4.3Topography

 

Topography was provided by CVME and was exported in digital exchange format (dxf) from an AutoCAD site map of the prospect. The topography dxf was imported and modeled in MicroMODEL. Because the topography did not cover the entire block model area in the southeast corner, this area was extrapolated from known topography using an inverse distance estimator. This remains a preliminary solution and surveyed or flown topographic control will be needed for future studies. The topography model was later used in the block to restrict estimation to only blocks below the topographic surface.

 

17.4.4Resource Estimation and Search

 

Grade estimation was performed using Micromodel mine modeling software. Five estimates were created using Ordinary Kriging (OK). The first three of these were duplicated using Inverse Distance Weighting (IDP) with a power of 2.5; and Nearest Neighbor (NN). This allows a comparison of the various methods to each other and to the data to determine the most appropriate fit. A staged estimate was performed in each method. First a single variogram search was performed that required P type samples from 2 separate drifts. This was restricted to a narrow window to insure interpolation between samples. Second a single variogram search was used allowing P type samples only from a single drift. Third a single variogram search was run using only X type samples in areas not previously estimated to fill in background grades. Finally, a 2 variogram search using both X and P samples was used to estimate an extended halo to show what possible ore might be in the area. The max 5 samples allowed for the 2ndand 3rd passes was restricted to minimize smoothing of grades. The 4th pass used a highly oriented search to extend vein material into likely areas. The 5th estimate used a 40m isotropic search to allow a halo of mineralization similar to the density of vein structures in the samples rock to form (Table 17-4).

17.4.5Resource Classification

 

According to the CIM Definition Standards,

 

An ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

 

An ‘Indicated Mineral Resource’ is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

 

Gustavson feels that with the vertical continuity exhibited in multiple drifts which appear to be in the same structure that the Pass 1 estimation can be classified as indicated. All other material must be considered inferred. With the addition of more surface samples and the samples from the Phase 2 planned drill holes, it is likely that some of the inferred resources will be upgraded to indicated. See Figure 17-5.

 

17.4.6Resource Summary

 

The estimated mineral resource is presented in Table 17-5 by the resource classification. Table 17-6 presents the resource as it was developed in multiple search passes. Gustavson feels that it is instructive to see the development of the resource in decreasing levels of confidence in addition to the basic criteria of Indicated and Inferred

19.INTERPRETATION AND CONCLUSIONS

 

Observations made during Mr. Crowl’s site visits confirm the descriptions of the gold mineralization provided by CVME. Surface expressions of past gold mining activity are common, with abandoned and overgrown workings dotting the hills in the immediate area of the prospect. Inspections underground revealed very narrow steeply dipping, strike-persistent mineralized quartz veins and quartz-filled fractures exposed over considerable drift lengths. The horizontal spacing between these very narrow quartz veins was not consistent in the areas visited. It is important for CVME to establish the vein density in the Toldafria area before further development decisions can be made. The concordant veins in the schist are far more sulfidic than the narrower vertical veins. The extent to which these veins are projectable for any appreciable distance will be directly related to the results of the proposed drilling program.

 

CVME’s initial exploration program has confirmed the presence of significant gold mineralization which has been mined on a small scale for more than a hundred years. Although the sampling was extensive in available underground workings, additional sampling such as core drilling will be needed to establish geological continuity of the 2 types of mineralization present. Given the mining history of the area with underground mines of much higher grade, and the close spacing of some of the known mineralized structures, it is reasonable to expect to expand the resource with further sampling using surface and/or subsurface core drilling as well as surface trenching.

 

The mineral resources estimated and reported herein are considered by Gustavson to meet the requirements of NI 43-101 for classification as indicated and inferred. Future efforts by CVME to better define the mineral system at Toldafria will allow for a consideration of re-classification.

20.RECOMMENDATIONS

 

CVME has conducted exploration to define an inferred resource of 947,000 ounces of gold at a cutoff of 0.5g/t and a small indicated resource of 5,100 ounces. Gustavson recommends that an exploratory drilling program be implemented to further define the resource and provided geologic and geostatistical support to better delineate vein systems. Further geologic investigations will be needed to ascertain an appropriate data density to establish geologic continuity of mineralization in 3 dimensions. Both surface and underground drilling are recommended.

 

20.1Proposed Phase 2 Exploration Program

 

20.1.1Underground Sampling

 

In CVME’s 2009 underground sampling program, 4000 m of tunnels were sampled. Following the same sampling methodologies, an additional 5000 m of tunnels were sampled in 2010 and early 2011. Minimal further underground sampling is contemplated in the Phase 2 program.

 

20.1.2Trenching

 

For the Proposed Phase 2 Exploration Program, no specific locations have yet been identified by CVME staff for trenches that will guide the positioning of subsequent drill holes.

 

20.1.3Drilling

 

Ten NTW 300 meter core holes are planned for Phase 2, comprising a total of 3000 m. Half of the holes will be sub-vertical, targeting to the sub-horizontal (concordant vein) structures and the other half in sub-horizontal holes, designed to cut the near-vertical vein structures. The location of the area to drill (around the block on which the Resources calculated) will provide a better knowledge of the deposit(s). The net result of drilling these holes may be the establishing of geological continuity to the mineralization and a 3rd dimension. The increased knowledge may allow estimation of indicated or measured mineral resources, upgrading the current inferred resources. The sampling is intended to be done on 3 m in the holes, yielding some 1000 samples.

 

20.1.4Metallurgical Tests:

 

Samples will be sent to Chile through the SGS laboratories. CVME intends to send approximately 200 kg of mineral samples selected from the rejects stored in the Toldafria sample warehouse to start a more comprehensive metallurgical study. The primary goal of the program will be to establish the behavior of gold in the deposit (degree of liberation, free gold, associations of gold to sulfides, etc) and to design possible metallurgical treatment flow sheets.

 

20.1.5Ore Microscopy and Laboratory Quality Control

 

Microscopic study of vein material may assist in determining the continuity of individual veins between the existing workings and new drilling, as well as the properties of the gold mineralization.

Gustavson further recommends that CVME develop a QA/QC system for their sampling program to further augment the quality control already provided by the assay lab. The following tables (20-1, 20-2 and 20-3) present the CVME exploration budget for the Phase 2 Exploration Program. Gustavson considers that the budget is adequate to accomplish the stated purpose of the program and to advance to the next decision point. Gustavson understands the Rio Novo Gold will carry out the above program of exploration starting in 2011.

Tabla 1. Resultados para las muestras de control Oreas 60b

 

Según las reglas del control de calidad para las muestras estándar, se tienen en cuenta los siguientes aspectos:

 

 

·Si el resultado de un estándar es mayor o menor que 3 desviaciones estándar a su valor medio es considerado como una falla (ver figura 1).
·Si los resultados de dos estándares adyacentes (mismo lado) son mayores o menores que 2 desviaciones estándar a sus valores medios eso es considerado como una falla (ver figura 1).

 

 

Figura 1. Gráfico temporal (valor Vs fecha) para Oreas 60b

 

 

 

Para la muestras de control Oreas 60b, no se detectó ninguna falla, todos los valores han demostrado una buena exactitud.

Tabla 4. Resultados para las muestras de control “Blank”

 

Si el resultado de un “blank” es 5 veces mayor que el límite de detección (DL) del análisis utilizado, es considerado como falla (para el caso de SGS es 25 ppb).

 

 

Con estas muestras de control estamos midiendo la contaminación durante el proceso de preparación en el laboratorio, pudiendo indicar también, mezclas entre muestras.

 

La figura 4, representa un gráfico temporal para los blancos, donde se grafican las muestras de control Blank y las muestras precedentes.

 

Figura 4. Gráfico Blank Vs muestra precedente

 

Todas las muestras de control analizadas hasta el momento, se encuentran por debajo del límite de detección (5 ppb) por lo tanto la tasa de contaminación en las muestras es cero.

 

1.1.3Duplicados de preparación

 

Duplicado tomado de la muestra triturada para medir la precisión del proceso de preparación y análisis del laboratorio. La variación debería ser menor que la de los duplicados de campo porque una muestra preparada correctamente es bastante homogénea.

Tabla 5. Resultados para las muestras de control, duplicados de preparación

 

A partir de los resultados obtenidos para los duplicados de preparación, se graficaron diagramas de dispersión que muestran la comparación entre dos conjuntos de datos de análisis.

 

De esta manera se observó que el 54% de las muestras presentan un porcentaje de diferencia mayor al 20%, razón por la cual se procedió a mandar las pulpas de las muestras a re-análisis.

1.1.4Duplicados de campo

 

Muestra de un mismo intervalo, tomada de manera idéntica a la muestra original, con el fin de medir la precisión (reproducibilidad) de todo el proceso de muestreo, desde el campo hasta la preparación en el laboratorio y análisis. Los duplicados de campo también pueden indicar el efecto pepita natural de las muestras, así que puede haber variaciones significativas entre el original y el duplicado.

Tabla 6. Resultados para las muestras de control, duplicados de campo

 

 

 

Se observó que el 90% de las muestras presentan un porcentaje de diferencia mayor al 20%, de acuerdo con el conocimiento que se tiene de Toldafría, el oro grueso encontrado en las muestras es bastante alto, indicando de esta manera el alto grado de influencia que tiene el efecto pepita natural en las muestras, sin embargo de acuerdo al programa de control de calidad se procedió a enviar a re-análisis las pulpas de las muestras, para así descartar los errores en cuanto a la precisión en el proceso de muestreo.

Project MS1271–Resource Development

1.0 BACKGROUND

 

On August 13, 2010, Met-Solve Labs received two buckets of samples from:

 

Ryan Allen

Resources Development Inc.

11475 W. I-70 Frontage Rd. North

Wheat Ridge, CO

Tel: 303-422-1176

 

 

The two buckets contain eighteen different samples (each packaged in two bags weighing a total of 2 kg). The sample labels are summarized in Table I.

 

Table I Sample

 

        
 Soft comp    Hard comp 
 CV 742-2    CV 707-5 
 CV 744-3    CV 701-9

 CV 737-11      
 CV 741-12      
 CV 731-17      
 CV 756-18      

 

 

The eleven soft and seven hard comp samples were combined to produced a single composite for testing.

 

An initial Falcon L40 test was done to test for centrifugal gravity recovery of gold. After promising results from the baseline gravity test, a program consisting of flotation and cyanidation system was added to evaluate the impact of these on the gravity concentrates and tails. Screen analyses were also done to determine particle size and gold distribution by size fraction.

Project MS1271–Resource Development

2.0 METHODOLOGY

 

 

The initial Falcon gravity test was done as per flowsheet shown in Figure 1 and the gravity-float- leach procedure was done as shown in Figure 2.

 

 

Figure 1 Gravity Test Flowsheet

 

 

Oversized material, which was too coarse to feed to the lab Falcon, was screened out prior to the first stage. This oversize was recombined with the first pass tails and ground prior to the second stage. An additional grind was applied after the second stages to increase gold liberation. The concentrates were panned to get an indication of achievable gold grades.

 

 

 

Figure 2 Gravity, Float and CN Leach Circuit

Project MS1271–Resource Development

For the second test, the feed material was ground down to target size prior to gravity concentration and thus no intermediate grinds were applied. The pan cons were assayed for gold, while the pan tails, the rougher and scavenger flotation concentrates were each subjected to a cyanide leach test.

 

The cyanide leach tests were conducted for 24 hours with 1,000 ppm NaCN at pH of 10.5. Intermediate solution samples were taken at 1, 3 and 6 hours. To stabilize the gold, extra cyanide was added to the solutions prior to submitting the samples to the assay lab.

 

3.0 RESULTS AND DISCUSSION

 

 

Detailed results are summarized in the Appendices as per Table I below.

Overall Flowsheet Summary  Appendix A
Gravity + Float Summary  Appendix B
Cyanidation Summary  Appendix C
Initial Gravity Test  Appendix D

Assay Summary  Appendix F

 

 

The general recoveries from the test work are presented in Table II below. Refer to flowsheet summaries presented in Appendix A and D for additional details.

 

Table II: Gold Recoveries

 

    
Test Operations  Gold Recovery (%)
Gravity Only Recovery (with intermediate grinds)  86.8
    
Gravity Only Recovery (direct grind)  83.0
Gravity + Float Recovery  92.8
Gravity+Float+Leach Recovery  85.7

Project MS1271–Resource Development

Gravity alone recovered an impressive 83 to 87% of the gold.

 

Floating the gravity tails raised the gold recovery to 93% with float tails assaying 0.22 g/t. The gravity tails (i.e. float feed) was calculated at 0.50 g/t.

 

Cyanide leaching of pan tails and float products

 

The cyanidation gold recoveries are summarized in Table III.

 

Table III Cyanide Leach Gold Recoveries

                
              Consumption (kg/t) 
 Test   Material   Gold Recovery (%)    NaCN    Lime (10%) 
 NL105   Pan Tail (NL103)   93.8    5.5    7.3 
 NL106   Float Rougher Con (NL104)   84.6    9.6    23.4 
 NL107   Float Scavenger (NL104)   75.4    10.1    27.0 

 

The cyanide and lime consumption for all three samples was relatively high. It is likely that the high sulfur content in all samples, particularly the float concentrates, contributed to the high cyanide consumption. The float rougher and scavenger concentrates contained 34% and 18% sulfur respectively (see Appendix F).

 

Note the sharp drop in cyanide concentration in the solution between 6 hours and 24 hours in both float concentrates. This corresponds to a substantial drop in pH in the same time period. For the cyanide leach on the float scavenger, the gold concentration drops between 6 and 24 hours and is likely due to the depletion of cyanide in solution overnight.

 

 

4.0 SUMMARY

 

 

Gravity alone recovered between 83 and 87% of the gold. Flotation of the gravity tails raised gold recovery to a 93%. When cyanidation is included, the gold recovery was found to be 86% as a result of incomplete leaching of the gold.

 

The high sulfur content of the pan tails and float products likely contributed to the high cyanide consumption.
