Section 1 - Summary

The Juniper Ridge Uranium Project (Juniper Ridge) is controlled by Energy Fuels Inc. and its USA subsidiary Energy Fuels Resources (USA) Inc. (EFR) and is located in southwest portion of the state of Wyoming, USA. Located 6 to 10 miles west of the town of Baggs, Wyoming, within a small closed subsidiary basin on the southeast flank of the Washakie Basin at approximately 41o 02’ 30” North Longitude, 107o 46’ West Latitude. The Project is accessible via 2-wheel drive on existing county and two-track roads.

EFR’s Mineral rights associated with the Project include 197 unpatented mining lode claims and one Wyoming State Mineral Lease. In total, these holdings comprise approximately 4,710 acres. Surface land ownership consists of federal lands administered by the United States Bureau of Land Management (BLM) and private lands.

Uranium was first discovered in this area in 1951, and commercial uranium mining occurred intermittently from 1954 until 1966. Seven companies mined uranium from twelve open pits and two shallow underground mines. During this time a total of 156,000 tons of material with an average grade of 0.172% U3O8 were mined resulting in production of 536,000 pounds of uranium (Pincock, Allen, & Holt, 1978).

Uranium mineralization in the Browns Park Formation within the project and surrounding area is described as Wyoming sandstone roll-type mineralization (Austin and D’Andrea, 1978).Uranium mineralization occurs within an eolian stratigraphic unit of the Miocene Browns Park Formation. Depth of mineralization averages slightly over 100 feet but ranges from near surface to a maximum of 292.5 feet, depending on location within the basin and local topography. Two general areas of mineralization occur within the Project, separated by less than 2 miles, which are herein referred to as Juniper Ridge East and Juniper Ridge West.

The deposit is relatively flat lying with formation dip less than 5°. The dip of the formation is highest at the margins of the basin and flatter near the center of the basin. The average thickness of mineralization above a 0.02% eU3O8 cutoff grade is slightly in excess of 10 feet.

Currently available drill data consists of radiometric equivalent data (eU3O8) for 2,167 historic drill holes and radiometric equivalent data (eU3O8) and Uranium Spectrum Analysis Tool (USAT) assay data for 400 drill holes completed during the 2011 drilling program and 149 drill holes competed in 2012.The 2011 drilling program was intended to verify historic drilling and replace historic data for drill holes shown on the maps but for which the radiometric data was not available. The 2012 drilling was intended to better define and expand the mineral resource; thus, the current database consists of 2,716 drill holes of which approximately 80% are historical and 20% are recent.

The primary resource calculation method utilized in this report is the Grade Thickness (GT) contour method. This method complies with the best practice guidelines specific to uranium for the estimation of mineral resources and mineral reserves, adopted by the CIM November 23, 2003 and is applicable to this type of deposit. Evaluation of radiometric equilibrium was based on 258 drill holes, with natural gamma and USAT data, completed in 2011 which met the cutoff criteria utilized in the mineral resource calculation. For the purposes of assessing the overall mineral resources for the project, it is recommended no correction for radiometric equilibrium be applied.

1


Based on drill density and verification drilling completed in 2011 and 2012, the mineral resource estimate meets the criteria for either Indicated Mineral Resources, as shown in Table 1.1, or Inferred Mineral Resources, as shown on Table 1.2, in accordance with the CIM Standards on Mineral Resources and Reserves. No current Pre-Feasibly Study or Feasibility Study has been completed for the Project. Thus, no Mineral Reserves are stated.

The base case for the Preliminary Economic Assessment (PEA) considers open pit mining in conjunction with on-site heap leach recovery, producing an intermediate uranium concentrate in the form of loaded resin which would be shipped to EFR’s White Mesa Mill, Blanding, Utah facility for final processing. However, once the uranium is concentrated and loaded on resin it could be shipped to other central processing facilities. Given the assumptions described herein, the PEA demonstrates a positive return on investment. Further studies may also consider alternatives of on-site upgrading with off-site processing.

This is a restricted disclosure as allowed under section 2.3(3) of NI 43-101 which includes a PEA and is preliminary in nature such that it includes a portion of the inferred mineral resources as reported in Section 14 of the report. The PEA is based on open pit mining and heap leach extraction of uranium values, utilizing methodologies, equipment, and a generalized design criterion which has been employed at the site and/or similar sites in the past but has not been specifically developed for the Project. Mineral resources are not mineral reserves and have not demonstrated economic viability in accordance with CIM standards. Inferred mineral resources are too speculative to have the economic considerations applied to them which would enable them to be categorized as mineral reserves, and there is no certainty that the outcomes estimated in the PEA will be realized.

The recommended base case for estimated mineral resources as highlighted in the foregoing tabulation is the 0.1 GT cutoff. This recommendation is based upon the author’s experience with successful open pit mining of similar deposits, including Maybell, Colorado and Gas Hills, Wyoming, which employed a similar cutoff criterion and the findings of the PEA.

The Project is located in an area which has been mined in the past. In addition, the most similar known uranium deposit, the Maybell project, was also mined in the past producing over 5 million pounds of uranium (Albretsen and McGinley 1982). It is the author’s opinion that the Project is best suited to conventional open pit mining in concert with either on-site beneficiation or upgrading with off-site processing of a concentrate. To the author’s knowledge, there are no conditions of a political or environmental nature that would preclude the development of the Project provided that all applicable state and federal regulations are met.

Mine development would require a number of permits depending on the type and extent of development. The major permits being the mining permit issued by the State of Wyoming Department of Environmental Quality, Land Quality Division, and the Plan of Operations approved by the BLM. Mineral processing for uranium would require a source materials license from the US Nuclear Regulatory Commission. To the author’s knowledge, these environmental permits have not been obtained. It is likely that an Environmental Impact Statement (EIS) would be required to obtain these permits.

Recommendations

Recommendations are broadly divided into the following major categories: drilling, metallurgical studies, preliminary feasibility studies, and baseline studies. The major categories are generally listed in order of importance although some studies need to be completed, all or partially for other studies to proceed. The recommendations that follow should be amended based on the results of other studies.

Summary

Expense Category
Estimated Cost*
Drilling $560,000
Metallurgical Studies $126,000
Preliminary Feasibility Study $190,000
Baseline Studies $90,000
Total Estimated Cost $966,000

Section 2 – Introduction

This Technical Report was prepared for EFR. The purpose of this report is to define the in-place mineral resources within the Juniper Ridge project and complete a PEA based on those resources.

Uranium mineralization in the Browns Park Formation within the Project and surrounding area is described as Wyoming sandstone roll-type mineralization (Austin and D’Andrea, 1978). The primary resource calculation method utilized in this report is the GT contour method which complies with the best practice guidelines specific to uranium for the estimation of mineral resources and mineral reserves, adopted by the CIM on November 23, 2003 and which is applicable to this type of deposit.

Originally, the historic data for the project area consisted of radiometric sampling (geophysical logging) from 5,423 drill holes in the vicinity of the property comprising 868,000 feet and more than 200 core holes with chemical analysis. Of this total, 4,871 were located on the previous mineral owner’s land holdings, the Agency General of International Petroleum (AGIP), and Italian State company (Pincock, Allen, & Holt, 1986). The original geophysical logs and chemical assay are not available. The drill data was stored on electronic media from which only portions of the data have been recovered. Currently available drill data consists of radiometric equivalent data (eU3O8) for 2,167 historic drill holes and radiometric equivalent data (eU3O8), and USAT assay data for 400 drill holes completed during the 2011 drilling program. In addition to the historical radiometric drill data, Crosshair Energy Corporation completed 400 drill holes in 2011. The current database consists of approximately 84% historical drill holes and 16% recent drill holes.

The following is a brief list of terms and abbreviations used in this report:

Cost data provided by EFR
  a) Property holding costs of $31,500 per year, subsequently verified by the Author.
b) Resin haulage costs from Juniper Ridge to the White Mesa mill estimated at $0.70 per pound, subsequently verified by the author.
c) Resin handling and uranium packaging cost at the White Mesa mill estimated at $2.60 per pound, not verified by the Author but in the Author’s opinion reliable for the purposes of this PEA.
Corporate Income Tax Analysis provided by EFR
a) A 20% effective tax rate for corporate income tax is recommended to be included in the economic analysis and reflects the most amount of taxes that would be due if the project alone were subject to U.S. income tax.
b) It is likely that the actual amount of cash taxes paid as a result of this project would be significantly less due to the following:
(1) Juniper Ridge is included in the Strathmore Resources (US) Ltd. corporate income tax return which has loss carry-forwards available to offset future income.
(2) Strathmore Resources (US) Ltd. may generate additional losses during the time frame of this model (2014-2030) from other development projects that produce losses that would be net against the income from Juniper Ridge.
(3) In addition, head office/general and administrative costs would be allocated to the project as part of a complete legal entity tax return and would reduce the actual cash taxes paid.

Wherever practical, this data was verified and confirmed. In part this confirmation was based on the author’s direct knowledge and work experience on the Project through his association with past operators. Wherever, information from the historic reports was used it is so referenced.

The author considers the data provided as reliable for the purposes of this report.

Section 4 – Property Description and Location

The Project is located in southwest Wyoming, 6 to 10 miles west of the town of Baggs, within a small closed subsidiary basin on the southeast flank of the Washakie Basin. Located at approximately 41o 02’ 30” North Longitude, 107o 46’ West Latitude.

Mineral rights associated with the Project include 197 unpatented mining lode claims and one Wyoming State Mineral Lease. In total, these holdings comprise approximately 4,710 acres. Surface land ownership consists of federal lands administered by the BLM and private lands. Mineral ownership consists of federal minerals administered by the BLM and Wyoming State Lands. Parcels within the Project with private surface lands are a split estate, i.e., the mineral rights are federal while the surface rights are private. The state lease is for minerals only. The land surface within the state lease is federal.

Mining claims and mineral leases locations utilized in the development of the Property Map, Figure 4.1, are representative of the approximate location of the mineral holdings. A listing of the mining claims was obtained from the Wyoming BLM and is provided in Appendix A. Legal surveys of unpatented claims are not required and, to the author’s knowledge, have not been completed. Mineral leases and claims establish mineral rights for uranium and other valuable minerals. The status of mineral leases and claims was confirmed. However, the location of the individual mining claims was not re-surveyed. Mineral lease 0-41095 (State of Wyoming) is valid through the 1st day of April, 2015 and is renewable, refer to Appendix A. The claims will remain the property of EFR provided that they adhere to required filing and annual payment requirements with Carbon County and the BLM. Carbon County and BLM records show the mineral claims to be current and active. Annual BLM payments are current through September 1, 2014.

The mining claims were originally located by Strathmore Resources Corporation in 2007 and were subsequently conveyed to Crosshair Energy Corporation. Details of that purchase agreement are provided in the Crosshair November 1st, 2010 News Release. Crosshair failed to complete the purchase arrangement and the property reverted to Strathmore in December of 2012. Through its purchase of Strathmore, EFR now controls 100% of the project. The previous agreement between Strathmore and Crosshair included a production royalty which is now null and void. To the author’s knowledge, no other royalties, agreements, or encumbrances exist on the property.

Uranium was first discovered in this area in 1951 and commercial production of uranium took place from 1954 until 1966. Seven companies mined uranium from twelve open pits and two shallow underground mines, as is further discussed in Section 6, History.

In addition, one operator, the Shawano Development Corporation, attempted various methods of on-site mineral processing including mechanical upgrading and vat leaching with both acid and alkaline lixiviants (Anctil, 1987). The historic mineral processing wastes associated with this operation were investigated under the Uranium Mill Tailings Radiation Control Act (UMTRCA) of 1978 and assigned a low priority (Albretsen and McGinley, 1982). In the late 1980’s the Wyoming Department of Environmental Quality, Abandoned Mine Lands Division (AML) covered and reclaimed the Shawano mineral processing site in place. To the author’s knowledge, no reclamation obligations to any private party exist with respect to mineral processing wastes within the project area.

8


Mining, both surface and underground, pre-dated the passage of the Wyoming Environmental Quality Act in 1973 and the Surface Mine Control and Remediation Act (SMCRA), August 3, 1977. In addition to reclaiming the Shawano mineral processing site, AML has conducted mine reclamation efforts within the project area. To the author’s knowledge, no reclamation obligations to any private party exist with respect to historic mine disturbances within the project area.

In order to conduct exploratory drilling of the property, a Drilling Notification (DN) from the State of Wyoming Department of Environmental Quality and the BLM will be required.

Mine development would require a number of permits depending on the type and extent of development. The major permits being the mining permit issued by the State of Wyoming Department of Environmental Quality, Land Quality Division (WDEQ/LQD), and the Plan of Operations approved by the BLM. Mineral processing for uranium would require a source materials license from the US Nuclear Regulatory Commission (NRC). To the author’s knowledge, these environmental permits have not been obtained. To obtain these permits, it is likely that an EIS would be required.

Within the general project area and vicinity oil and gas wells and infrastructure exist. Currently the oil and gas wells and infrastructure are not in conflict with the known mineral resource areas. As federal lands are subject to multiple uses, there is a risk that future oil and gas development and/or related infrastructure could be in conflict with mineral development.

The mineral tenure of the project is based on unpatented mining lode claims established through the US Mining Law of 1872. Changes in US mining law could affect mineral tenure.

To the author’s knowledge, there are no other significant factors that may affect access, title, or the right to perform work on the property.

Section 5 – Accessibility, Climate, Local Resources, Infrastructure and Physiography

Accessibility

The Project is located 6 to 10 miles west of Baggs, Wyoming and approximately 3 miles north of the Colorado-Wyoming border. (Refer to Figure 5.1 – Location and Access Map). The Project is accessible via two-wheel drive on existing county and two-track roads by proceeding one mile north of Baggs, Wyoming on Highway 789, then west on Carbon County Road 144 (Poison Buttes Road), towards Poison Buttes approximately 6 miles where the road crosses the Project for the next 4 miles.

Climate

Historic climate records were available through a National Weather Service cooperative station in Baggs until 2000. The Project falls within the intermountain semi-desert weather province within the Green and Bear Drainage. Although winter conditions can be severe, including local ground blizzards, such conditions would not preclude year round operations. The following is a summary of the climatic conditions from 1971 to 2000 from the US National Weather Service:

Physiography

The Project is located within the Wyoming Basin physiographic province within a small closed subsidiary basin on the southeast flank of the greater Washakie Basin. The elevation of the Project site is between 6,000 and 7,000 feet above mean sea level. The topography is characterized by gently rolling hills which are cut by some ephemeral streams draining into the Little Snake River, approximately 3 miles south of the Project. The dominant vegetation consists of juniper trees, native grasses, sagebrush, and other shrubs typical of the continental, arid climate in the Western United States.

Infrastructure

In addition to site access, mine development will require utilities and water supply. The nature and scope of the mine operations will greatly influence utility and water supply demands. Utility services, including natural gas, electricity, and communications, are located in Baggs, Wyoming which is 6 miles from the eastern boundary of the Project. Water supply could be obtained from locally permitted and constructed wells or from surface water sources including the Little Snake River approximately 3 miles south of the project area. Water rights for both surface and ground water are administered by the Wyoming State Engineer’s Office and are subject to prior water rights. Options for on-site power demands would include extension of existing service to the Project or the generation of power on site.

Local Population

The nearest community is the town of Baggs, Wyoming. The 2010 census shows a population of 348, (refer to www.townofbaggs.com). The nearest population center is Craig, Colorado located approximately 41 miles south of Baggs, Wyoming. According to the Chamber of Commerce, Craig’s population was 9,251 as of the 2010 US census (>www.craig-chamber.com/ profile.html).

Surface Rights

The 1872 Mining Law grants certain surface rights along with the right to mine provided the surface use is incident to the mine operations. In order to exercise those rights the operator must comply with a variety of State and Federal regulations (refer to section 20). For the mine operations, as described in Section 16, the author concludes that EFR has and/or can obtain, through permitting and licensing of site activities, sufficient surface rights for the planned operations.

Section 6 – History

Past Production

Uranium was first discovered in this area in 1951, and commercial uranium mining occurred intermittently from 1954 until 1966. Seven companies mined uranium from twelve open pits and two shallow underground mines. During this time, a total of 156,000 tons of uranium material with an average grade of 0.172% U3O8 were mined resulting in production of 536,000 pounds of uranium. (Pincock, Allen, & Holt, 1978). Some of the operators included: the Shawano Development Corporation, Trace Elements (later acquired by Union Carbide Corporation), Teton Minerals, Parker-Thomas, and Leckenby. Underground mining was conducted by Basin Engineering Company under contract to Teton Minerals. Mined ores were shipped to a variety of mills including: Union Carbide’s mills located in Rifle and Maybell, Colorado, Western Nuclear’s Split Rock mill near Jeffrey City, Wyoming, and Atomic Energy Commission (AEC) ore buying stations (Anctil, 1987). Shawano Development Corporation attempted various methods of on-site processing including: mechanical upgrading using a spiral classifier to separate sand and slimes with the uranium values expected to report to the slimes, acid vat leach with ion exchange recovery, and carbonate-bicarbonate vat leach which produced a sodium diuranate concentrate. The concentrate was subsequently purchased by the (AEC), (Anctil, 1987).

Ownership and Control

Site activities were limited during what is referred to as the “Stretch Out” period beginning in the mid 1960’s and continuing into the early 1970’s. During this period, AEC supply contracts were being phased out and private utilities began to enter the uranium market. In 1973, Homestead Mineral Corporation (HMC) controlled most of the mining claims and leases in the area, with the exception of those held by Union Carbide Corporation (UCC). In that same year, Minerals Exploration Company (MECO) in joint venture with Urangesellschaft (UG) acquired the property from HMC. In 1975, UG purchased MECO portion of the joint venture acquiring 100% interest in the property (Pincock, Allen, & Holt, 1978). However, UCC maintained its mineral claims in the area. In 1981, AGIP acquired the property from UG (Pincock, Allen, & Holt, 1986) and in 1982 CoCa Mines acquired the mineral interest of UCC (Anctil, 1987). Subsequently, mineral leases and claims were allowed to expire during the extended lull in the uranium market which began in the late 1980s.

Beginning in 2005 Strathmore Resources, through Miller and Associates, acquired Wyoming State Mineral Lease 0-41095 and located the unpatented mining lode claims that comprise the current Project. On January 30, 2007, Strathmore entered into a joint venture agreement with Yellowcake Mining Inc. to develop the Juniper Ridge property. The JV was dissolved in December 2008. On November 1, 2010, Crosshair entered into a purchase agreement with Strathmore for the property (www.crosshairexploration.com). Crosshair failed to complete the terms of the purchase agreement and so in 2012 the Project reverted to Strathmore. With the acquisition of Strathmore, EFR now controls the Project. The Project now encompasses portions of both the former AGIP and CoCa Mines mineral holdings.

Historic Exploration

The most recent of the historic technical studies (Pincock, Allen, & Holt, 1986) state that the study was based on radiometric sampling (geophysical logging) from 5,423 drill holes in the vicinity of the property comprising 868,000 feet, of which 4,871 of these drill holes were located on the AGIP mineral properties. The previous historic feasibility study (Pincock, Allen, & Holt, 1978) states that their mineral resources/reserve estimates were based on radiometric assays from 3,935 drill holes.

The previous historic technical studies and reports also address radiometric equilibrium. The data available over time for evaluation of radiometric equilibrium also varied. In 1982, an internal project summary report (Beahm, 1982) radiometric equilibrium was evaluated based on data from 200 core holes. For that study, only core holes with greater than 80% sample recovery were included and only samples with uranium grades greater than 0.04% U3O8 were used. This study reported a positive disequilibrium factor of 1.017:1 (chemical to radiometric). The subsequent feasibility study (Pincock, Allen, & Holt, 1986) evaluated individual core samples representing a total of 321.5 feet of core, but does not specify the number of core holes from which the samples were taken. Independent sampling and assaying of core and independent radiometric log determinations were completed by the authors of the 1986 report. They concluded that while there was some bias in the estimation of mineralized thickness based on radiometric interpretation, there was no bias in grade. The older feasibility study by UG (Pincock, Allen, & Holt, 1978) evaluated radiometric equilibrium based on 125 mineralized intervals from three separate geographical areas at a 0.02% minimum gradeU3O8. This study recommended an adjustment of grade by an overall negative disequilibrium factor of 0.90.

The historic data utilized to evaluate radiometric equilibrium in these reports is generally not available for incorporation into this Technical Report. As discussed in Section 14 of this report, current data with respect to radiometric drilling is available from some 549 recent drill holes.

Historic Estimates

Historic mineral resource estimates are available for the project area from at least three sources. Both UG and AGIP completed technical studies for the project area in (Pincock, Allen, & Holt, 1978) and (Pincock, Allen, & Holt, 1986), respectively. These reports were for the same mineral holdings but excluded the adjacent mineral holdings of UCC. CoCa Mines, following their acquisition of the UCC mining claims, stated historic mineral resource estimates for the UCC mineral holding (Anctil, 1987). These historical estimates are summarized in Table 6.1.

15


The UG and AGIP estimates were based on slightly different data, varying calculation methods, and assumptions. Notably, the AGIP estimates had additional data from drilling conducted subsequent to the acquisition of the property from UG. AGIP used a 0.03% eU3O8 cutoff grade compared to the 0.02% eU3O8 cutoff grade used by UG. The CoCa Mines estimate was for a separate but adjacent property and was based on a 0.05% eU3O8 grade cutoff.

Section 7 – Geologic Setting and Mineralization

Introduction

The geologic setting and mineralization within the Project area and the vicinity is well documented in the professional literature as well as internal historical reports from past mineral owners. The earliest published report for the area is by Vine and Prichard, 1954, AEC geologists. They discovered anomalous radioactivity in the Browns Park Formation in the vicinity of the Project on October 15, 1953 as a result of a reconnaissance with a car-mounted recording scintillation detector (Vine and Prichard, 1954). More recent reports include the “National Uranium Resource Evaluation (NURE); Rawlins Quadrangle, Wyoming and Colorado” (Dribus and Nanna, 1982) which designated the project area as Area B, refer to pages 25 through 36. Also in 1982, the Project area is described in the “Ore Deposits of Wyoming”, (Hansel, 1982). Internal project summary and technical studies include: UG, 1978, AGIP Mining 1982 and 1986, and CoCa Mines (Anctil, 1987).

The following description of the mineralization in what was termed Area 15 in their report, which corresponds to the project area, is taken from Dribus and Nanna, 1982, pp. 31-33:

Vine and Prichard (1954) reported that most of the mineralized sands in Poison Basin are brown to reddish brown, contain from 0.004% to 0.39% uranium, and are characterized by radiochemical disequilibrium in favor of equivalent uranium, relative to actual uranium present. Samples of black sandstone collected by Vine and Prichard show roughly equal values of equivalent and chemical uranium content. These samples were from unaltered sands and probably contained the uranium oxide uraninite, which is reported as an ore mineral in the “primary zone” of the Poison Basin district by the U. S. Atomic Energy Commission (1959). Unaltered sands have not been leached of their uranium content by weathering processes; hence, radiochemical equilibrium is maintained.

A sample of mineralized, altered sandstone collected by Vine and Prichard (1954) contains 3.21% uranium and shows pronounced radiochemical disequilibrium in favor of actual uranium relative to equivalent uranium. This type of disequilibrium, in favor of actual uranium, characterizes uranium ores in the Browns Park Formation of the Maybell-Lay area in Colorado. Grutt and Whalen (1955) suggested the “the tendency of unoxidized ore to contain more uranium than is indicated by radiometric assay, may indicate youthful formation of the deposits.” An unaltered sand (MFA 005) from uranium occurrence 82 and an altered sand (MFA 240) from uranium occurrence 91 also reflect higher uranium values than indicated by equivalent results (Table 4 and App. B1). These values suggest that uranium concentration mechanisms in the Browns Park Formation have been operative in recent times and that some of the uranium has not had sufficient time to decay and produce radiogenic daughters.

17


Geologic Setting

The general geologic setting of the Project is shown in plan on Figure 7.1, Geologic Map, and in profile on Figure 7.2, Geologic Cross Section.

The Project is located within a small subsidiary basin on the southeast flank of the Washakie Basin. The Project encompasses the majority of the outcropping of the Browns Park Formation which was preserved in the basin over an area of approximately 10 square miles. This basin and the larger Powder Spring Basin, about 15 miles to the west, appear to be small tectonic grabens down-dropped post Eocene, but pre-Browns Park in time (Pincock, Allen, & Holt, 1986).

Structural Geology

The dominant structures of the area, directly related to the grabens, are the east-west trending, high angle, normal faults. These faults are mapped as bounding the north side of the basins, but in all probability they bound the south side as well, although these east-west faults trend into the Poison Basin, they do not appear to affect the Miocene rocks and, thus, are dated as being pre-Miocene. In addition to these faults, northeast and northwest, high angle, normal faults have been noted cutting the Browns Park into the Poison Basin. These faults are said to show only minor displacements. Minor folds trending east to west cut through the basin, but the effects on the Browns Park are not significant (Pincock, Allen, & Holt, 1986).

Stratigraphy

The following stratigraphic description is taken largely from Pincock, Allen, & Holt, 1986.

While formations ranging in age from Cretaceous to Quaternary are exposed at the surface within the vicinity, only the Eocene and Miocene formations play a significant role in the location and tenure of mineralization. Upper Eocene and Miocene age sediments fill the Poison Basin. Oligocene rocks are absent, having been completely eroded away before Miocene deposition; Miocene rocks lie unconformably on upper Eocene rocks in the basin and host the known uranium mineralization within the project area.

The Eocene series in the basin are represented by the Wasatch and Green River Formations. The aggregate thickness of these formations in the region ranges from 2,000 to 4,000 feet.

The Wasatch Formation in the area is composed of variegated mudstones, claystones, siltstones, sandstones, and conglomerates. Deposition is considered to have occurred largely in lacustrine, piedmont, and plaudal environments, but eolian and fluvial environments are represented as well.

18


The Green River Formation consists of shales, mudstones, sandstones, and marlstones largely deposited in the lacustrine environments. The Tipton Tongue member of the Green River Formation has limited exposure in the area cropping out along the northern rim of the basin, where it is predominately a claystone with interbedded of marlstone and sandstone.

The Browns Park Formation is the only stratigraphic unit of Miocene age found within Project and immediately surrounding area. The Browns Park is a sedimentary formation which was deposited unconformably on a highly irregular erosion surface which truncates upper Cretaceous through Eocene strata. The base of the Browns Park is conglomerate overlying the Wasatch Formation which consists mainly of quartzite and igneous pebbles in a sandstone matrix. Crossbedding, irregular bedding surfaces, and clay lenses suggest that this conglomerate is of fluvial origin. However, some authors have suggested that this lower conglomeratic unit may represent pediment gravels (Vine and Prichard, 1954). Thickness of the unit ranges from 5 to 75 feet.

Overlying the basal conglomerate is the Upper Browns Park, consisting of a tuffaceous, feldspathic sandstone. The Upper Browns Park is fine grained, moderately to poorly sorted, friable sandstones in which the grain size is bimodal, i.e., larger grains – quartz, chert, and clastic volcanic fragments – are set in a fine to very fine-grained tuffaceous sandstone containing quartz and feldspar. The dominant sedimentary structures within the unit are small to large scale festoon and planar cross-bed sets ranging up to several feet in thickness. Based on the roundness of quartz grains, the frosted nature of quartz grains, and the character of the cross-beds, the upper portion of the Browns Park is interpreted to be of eolian origin. The thickness of the upper portion of the Browns Park Formation within project area varies due to erosion reaching a maximum thickness of approximately 300 feet.

Although the Wasatch Formation is known to host uranium mineralization in other areas of Wyoming, all known uranium mineralization within the project area is hosted within the upper Browns Park Formation.

Mineralization

Uranium mineralization occurs within an eolian stratigraphic unit of the Miocene Browns Park Formation. The host unit consists of tuffaceous, feldspathic sandstone which exhibits small to large scale festoon and planar cross-bed sets ranging up to several feet in thickness. Generally, uranium mineralization is the roll-front type mineralization, common to the uranium basins in Wyoming (refer to Section 8). Localization of uranium appears to relate to permeability and the presence of pyrite or hydrogen sulphide (Pincock, Allen, & Holt, 1986). The depth of mineralization averages slightly over 100 feet, but ranges from near surface to a maximum of 292.5 feet depending on location within the basin and local topography. Two general areas of mineralization occur within the Project, separated by less than two miles, which are herein referred to as Juniper Ridge East and Juniper Ridge West.

19


The deposit is relatively flat lying with formation dip less than 5o. The dip of the formation is highest at the margins of the basin and flatter near the center of the basin. The average thickness of mineralization above a 0.02% eU3O8 cutoff grade is slightly in excess of 10 feet.

The distribution of the mineralization is shown in plan view on Figure 14.1 and 14.2 for Juniper Ridge East and West, respectively. More than 80% on the known mineralization occurs within the Juniper Ridge East portion of the Project.

Historic feasibility reports, AGIP, 1986 and UG, 1978, discuss the continuity of mineralization. These reports express some concerns relative to the continuity of mineralization especially with respect to grades necessary to support mining. AGIP, 1986 states that continuity at very low grades, i.e., a cutoff of about 80 ppm, is excellent and mineralization appears nearly continuous for several thousand feet throughout much of the main property area. However, the degree of continuity decreases with increasing grade. At grades above 500 ppm U3O8, continuity of mineralization may range between tens of feet to several hundred feet. Continuity of most mineralized zones is generally less than 50 feet.

Figure 7.3, Core Hole Series JR 233, provides a graphical representation of the variability of the mineralization. This series of core holes was completed in 2011 to obtain samples for metallurgical testing. The five core holes in this series represent 10 foot offsets or the variability over a span of 50 feet. In each hole, an interval of 15 to 16 feet was cored at approximately the same depth. For these five holes, the average grade ranged from 0.012% to 0.055% U3O8; the average thickness of mineralization above 0.02% U3O8 ranged from 3 to 12 feet; and the GT 0.02% U3O8 ranged from 0.081 to 0.729.

It is the author’s opinion, based on personal knowledge of the site, having managed the exploration and development drilling for the project for AGIP and through mine production experience at a very similar Browns Park hosted deposit located near Maybell, Colorado, that the forgoing statement relative to the continuity of the deposit is largely correct. Portions of the uranium deposits at Juniper Ridge and at its sister deposits near Maybell, Colorado have been mined successfully in the past. Past operations have compensated for the variability in grade by delineating areas to be mined by open pit by drilling on 50 foot centers and instituting rigorous in-pit grade control programs.

Section 8 – Deposit Types

Uranium mineralization in the Browns Park Formation within the Project and surrounding area is described as Wyoming sandstone roll-type mineralization (Austin and D’Andrea, 1978).

While local mineralization displays some of the characteristics of known uranium deposits in the Gas Hills and Southern Powder River Basin of Wyoming, the mineralization is not necessarily typical of Wyoming roll-front deposits. The uranium mineralization within the Project is sandstone hosted and was deposited along a geochemical solution front, as is typical of roll-front mineralization and similar to other Wyoming sandstone hosted uranium deposits. The features which distinguish mineralization within the Browns Park Formation harken to its eolian origin and include the absence of carbonaceous trash and lack of stratigraphic controls, i.e., the lack of distinct vertical variations in grain size and the lack of intervening finer grained units (Rackley, 1972).

The source of uranium is described as syngenetic, alteration of the tuffaceous volcanic materials within the Browns Park Formation and/or the immediately overlying North Park Formation liberated uranium which was transported by ground water and concentrated along oxidation/reduction interfaces within the formation (Dribus and Nanna, 1982).

The localization of uranium appears to relate to local variations in permeability and the presence of pyrite and/or hydrogen sulphide. Uranium mineralization, in general, appears to be of the roll-front type mineralization common to the uranium basins in Wyoming, cutting across sedimentary structures (Pincock, Allen, & Holt, 1986).

24


Section 9 – Exploration

To the author’s knowledge, no relevant exploration work other than drilling, as described in Section 10, Drilling has been conducted on the property by Crosshair. The ownership of the recent drilling and other data passed from Crosshair to Strathmore and then from Strathmore to EFR.

The Project is located within a brownfield site which has experienced past mine production, extensive exploration, and development drilling. The initial discovery was based on ground radiometric surveys reported in 1953 but since that time exploratory work has been primarily drilling.

25


Section 10– Drilling

Currently, available drill data consists of radiometric equivalent data (eU3O8) for 2,167 historic drill holes, radiometric equivalent data (eU3O8), and USAT assay data for 400 drill holes completed during the 2011 drilling program and 149 drill holes completed in 2012. For the 2011 drilling program, downhole logging of the drill holes was completed using standard gamma technology as well as a uranium spectral analysis tool (USAT), supplied by Century. The USAT method measures the gamma intensity of Pa234, the short-lived (t½ = 6.7 hr) second daughter product of U238. U238 reaches secular equilibrium with Pa234 within approximately 4 months. Thus, USAT gives a nearly direct measurement of uranium content which can then be directly compared to radiometric equivalent data (eU3O8), to determine the equilibrium state of the uranium mineralization intersected in the hole. Radiometric equilibrium conditions are discussed in Section 14, Mineral Resource Estimates, in this report.

The 2012 drilling was intended to better define and expand the mineral resource. Thus, the current database consists of 2,716 drill holes of which approximately 80% are historical and 20% are recent. Verification of historic data is discussed in Section 12, Data Verification.

Drill data available for this estimate is summarized in Table 10.1.

Table 10.1: Drillhole Data

Total 2,716 862 478 850 283 243

All drill holes, both historic and recent, were shallow (less than 300 feet) and drilled vertically. The dip of the Browns Park Formation within the Project varies from as much as 5o on the margins of the basin to essentially flat near the center of the basin (Vine and Prichard, 1954). The surface location of the drill holes is shown on Figure 10.1, Drill Hole Location Map. This figure distinguishes between the historic and recent holes and shows the general outline of mineralization which meets a minimum grade of 0.02% eU3O8 and a minimum GT of 0.10.

Both grade and GT distribution are log normal. However, the range was not extreme with grade above cutoff ranging from 0.02% eU3O8 to a maximum of approximately 1% eU3O8 and GT above cutoff ranging from 0.10 to just over 5. High grade and/or GT holes were used in the resource calculation. However, as discussed in Section 14-Mineral Resource Estimates, the area of influence allowed in the calculation was limited.

26


Drift surveys of the drill holes were generally not completed because the drilling was shallow and the dip of the formation reasonably flat. Even at a maximum dip of 5o and given the average mineralized thickness of approximately 10 feet, the difference between the measured vertical thickness and the true thickness measured perpendicular to dip would be less than 0.04 feet, i.e., 9.96 feet as compared to 10 feet.

Typical Cross Sections

Typical cross sections are shown for the most significant area of mineralization within the Project located in the southwestern portion of the Juniper Ridge East mineral resource area. The location of the cross sections is shown on Figure, 10.2. Detailed cross sections are shown on Figure 10.3, Radiometric Cross Sections. All data presented in the cross sections is from the 2011 program.

The cross sections are located along and transverse to the general trend of mineralization, spanning 1,200 feet along trend and 1,000 feet across trend. The cross sections show:

  • Anomalous Radioactivity is continuous horizontally along and across the mineralized trend for more than 1,000 feet in either direction.
  • Individual drill holes have vertically continuous zones of anomalous radioactivity over a thickness of approximately 150 feet.
  • There is no discernible lithological difference within the vertically continuous zone of anomalous radioactivity. Thus, treating the mineralization as a single horizon is justified.
  • There are distinct variations in the thickness and grade of higher grade mineralized intercepts.

These cross sections support the conclusions of previous studies relative to the continuity of mineralization as discussed in Section 7, Geologic Setting and Mineralization.

Section 11 – Sample Preparation, Analyses, and Security

The primary data collected for this Project is the downhole radiometric, USAT geophysical log data, and the lithological descriptions of the drill cuttings. For the 2011 and 2012 drilling programs, downhole geophysical logging of the drill holes was provided by a recognized commercial vendor, Century. The geophysical log data was provided to Crosshair in electronic format. Lithologic descriptions, along with drill hole number and survey coordinates, were recorded on-site with a data recorder. Qa/Qc of the data was completed by the project manager and the electronic data transferred to Crosshair’s data server with weekly back up.

Seventeen core holes were completed during the 2011 drilling program primarily to provide samples for metallurgical testing. Following field lithologic description, the core was placed into plastic sleeves which were sealed to prevent oxidation. The core was then placed into standard core boxes and temporarily stored in a secure facility leased from Grieve Enterprises in Baggs, Wyoming.

The author observed the core storage and examined some of the core which had been collected. The core samples were sealed in plastic bags to prevent oxidation and stored in core boxes which were labeled as to the hole number and footage interval. At that time, no core had been prepared or shipped for assay; however, the basic protocol of maintaining a chain of custody and obtaining assays from a certified lab was discussed. No core data was available at the time this report was prepared. This was not necessary for the mineral resource estimate as the estimate is based on radiometric equivalent data with the USAT data utilized to evaluate radiometric equilibrium.

In summary, the data needed for completion of the mineral resource estimate provided herein was collected and preserved to generally accepted industry standards and in the author’s opinion is appropriate for the stated purpose of this report.

The historic database was originally developed by UG, and through completion of their feasibility study of the Project area, the database consisted of a down-hole radiometric equivalent assays from 3,935 drill holes (Pincock, Allen, & Holt, 1978). UG utilized the commercial geophysical logging services of Century for on-site geophysical logging. Century provided the data to UG both as hard copy original geophysical logs and as digital data with downhole CPS converted to eU3O8 by ½ foot intervals. AGIP continued with the practice of using the logging services of Century for on-site geophysical logging and digital data with down-hole CPS converted to eU3O8 by ½ foot intervals. At the time AGIP completed their feasibility study, (Pincock, Allen, & Holt, 1986) stated that their study was based on radiometric sampling (geophysical logging) from 5,423 drill holes in the vicinity of the property comprising 868,000 feet of which 4,871 of these drill holes were located on the AGIP mineral properties.

32


Note that the foregoing statement relative to the historic radiometric equivalent database is based on information provided in the technical studies, AGIP, 1986 and UG, 1978 in part, but is also based on the direct personal knowledge of the author who managed the drill hole database on behalf of AGIP during the period of 1982 through 1986. The author personally vetted and confirmed the database as did the independent authors of the historic technical studies. The author can further attest that the original geophysical, lithologic, and other relevant data was in AGIP’s possession at the time the database was finalized for use in the 1986 feasibility study. As a cautionary note, no recent drilling has been completed in the Juniper Ridge West area. However, the author has supervised drilling in this area in the past and the database for this area was created in the same manner and concurrently with that for Juniper Ridge East. Thus, it is the opinion of the author that the historic databases for both Juniper Ridge West and East are equally valid.

Subsequent to AGIP relinquishing the property, the database was not fully preserved. A portion of the data was retrieved from magnetic media. Currently available drill data consists of radiometric equivalent data (eU3O8) for 2,167 historic drill holes and radiometric equivalent data (eU3O8). Drill hole location maps are available which show the locations of the great majority of historic drill holes whether or not the downhole radiometric data was retrieved. The original geophysical logs are not currently available.

In addition to the historical radiometric drill data, 400 drill holes were completed in 2011 and an additional 149 drill holes in 2012. As with previous mineral owners, the commercial geophysical logging services of Century were employed. The 2011 drilling program was intended to verify historic drilling and replace historic data for drill holes shown on the maps but for which the radiometric data was not available. The 2012 drilling was intended to better define and expand the mineral resource. As a result, the current database consists of 2,716 drill holes of which approximately 80% are historical and 20% are recent.

Of the 400 drill holes completed in 2011, sixty-nine were completed within 25 feet of a drill hole with historic radiometric data. With respect to GT above a cutoff of 0.02% eU3O8;

  • Ten 2011holes varied by less than 0.1 GT as compared to historic data.
  • Twenty-three 2011 drill holes had a GT that was lower than historic drill data by more than 0.1 GT but less than 1.0 GT.
  • Eighteen 2011 drill holes had a GT that was higher than historic drill data by more than 0.1 GT but less than 1.0 GT.
  • Twelve 2011 drill holes had a GT that was lower than historic data by more than 1.0 GT.
  • Six 2011 drill holes had a GT that was higher than historic data by more than 1.0 GT.
  • Overall the GT from the 2011 drill holes were slightly lower than the comparative historic data.

33


It is the author’s opinion that the variances in the comparison of historic and recent data are related primarily to variations related to continuity of grade rather than variations in assay methodology and/or equipment. Section 7- Geologic Setting and Mineralization, discusses the continuity of grade observed in the deposit and provides an example of the grade variation in closely spaced drilling from the 2011 program.

In conclusion, it is the author’s opinion that current radiometric database consisting of a mixture of historic and recent dill data is reliable for the purpose of estimating mineral resources for the following reasons:

  • The historic and current radiometric data were developed by a commercial geophysical logging company. The same commercial logging company, Century, was employed for both the historic and current drilling programs and is one of the principal companies providing such logging services for the uranium industry in the US.
  • The companies which previously controlled the project area were involved in uranium exploration in the US and abroad. These companies followed generally accepted industry practices.
  • The historic radiometric data was vetted and verified independently for two separate technical studies commissioned by the previous owners of the Project area.
  • The procedures employed during the 2011 drilling program were observed and reviewed by the author and followed generally accepted industry practices.
  • The 2012 drill data was reviewed by the author and was found to be consistent with the 2011 drill data.
  • The author has direct personal knowledge as to the veracity of the historic database having managed the database during the period of 1982 through 1986.

Historic Radiometric Equivalent Database

Although the results and general conclusions of previous studies of radiometric equilibrium are known, the historic data utilized to evaluate radiometric equilibrium in these reports is generally not available. The current data for evaluation of radiometric equilibrium is available from the 400 drill holes completed in 2011 for which there is both radiometric equivalent data and USAT data available. USAT logging is a commercially available product. Calibration of the USAT tool and comparison to chemical assays is provided in Appendix B of this report.

It is the author’s opinion that this method of assessing radiometric equilibrium is appropriate and reliable for this project and that the volume of data is sufficient to reasonably determine radiometric equilibrium conditions for the purposes of estimating mineral resources. The evaluation of radiometric equilibrium is provided in Section 14, Mineral Resource Estimates.

Sample Location

The initial plane surveying system was established using standard plane surveying techniques by UG and maintained by AGIP. The survey control system was created prior to the advent of current GPS technology. When the author managed the project on behalf of AGIP, all surveying of drill holes, mining claims, and control for aerial mapping was completed by an independent Professional Licensed Surveyor (PLS) and all surveying was completed within accepted mapping standards. Initial drill hole locations were staked out by the surveyor and the final locations of all drill holes surveyed following drilling. The surveyor utilized total station survey equipment which provided a digital record of coordinates and elevation accurate to a few tenths of a foot.

34


Recent drill hole surveys were completed using a Trimble pro XH with a pole mounted tornado antenna. Field data was post-processed with Trimble Pathfinder Office and referenced to three fixed public reference stations. Recent drill hole surveys were not tied into the on-site control net although both surveys report coordinates and elevations in the NAD 83 Wyoming State Plane system. The recent survey methodology should yield sub meter accuracy with respect to both coordinates and elevation but has not been verified.

Density of Mineralized Material

The density of mineralized material used in the historic technical studies, (Pincock, Allen, & Holt, 1986) and (Pincock, Allen, & Holt, 1978) was 16.3 and 17 cubic feet per ton, respectively. Although there was some test data available for the determination of density the factors, the data is not specifically provided in the reports nor was it available for this study. The previous studies both recommended further testing to determine the density. For the purposes of this report the author recommends a density factor of 16 cubic feet per ton based on direct personal experience with mining operations in similar sandstone hosted deposits in Gas Hills, Wyoming and Maybell, Colorado.

The maximum variance in the estimation of mineral resources based on density in the range of 16 to 17 cubic feet per ton is approximately 6%.

35


Section 13 – Mineral Processing and Metallurgical Testing

Current metallurgical testing has not been completed. However, the deposit has been mined and the product from that mining shipped to conventional mills and recovered. As documented in Section 6-History, commercial uranium mining occurred intermittently from 1954 until 1966. Mined product was shipped to a variety of mills including: Union Carbide’s mills located in Rifle and Maybell, Colorado, Western Nuclear’s Split Rock mill near Jeffrey City, Wyoming, and AEC ore buying stations (Anctil, 1987). These uranium mills were acid leach facilities.

This historical production from the project demonstrates that uranium is recoverable from the mineralized material. In addition, previous owners completed metallurgical studies and incorporated the findings of those studies in technical studies, as summarized in Table 13.1, (Pincock, Allen, & Holt, 1978) and (Pincock, Allen, & Holt, 1986). While the actual metallurgical studies are not available, Table 13.1 is a summary of the findings as provided in the technical studies.

AGIP 1986 Alkaline 540 maximum 0.06-0.12% U3O8 88.3 – 92.9 %

Factors which will affect mineral processing recoveries and costs include;

  • The grade of the mined material. The solid loss is relatively constant. Thus, the higher the mill feed grade the higher the percentage recovery.
  • The calcium carbonate concentrations, which in some areas are in the range of 6 to 8% (AGIP, 1982).
  • If alkaline lixiviant is used, recoveries are expected to be lower than acid lixiviant and alkaline lixiviants will have a tendency to cause the clay fraction in the leach material to swell which may not be desirable depending on the methodologies for mineral processing and tailings disposal.
  • In situ recovery would generally not be favorable due to relatively low permeability, lack of confining units, and a substantial portion of the mineralization occurring above the water table.

Section 14 – Mineral Resource Estimates

Based on drill density and verification drilling completed in 2011 and 2012, the mineral resource estimate meets the criteria for either Indicated Mineral Resources, as shown in Table 14.1, or Inferred Mineral Resources, as shown on Table 14.2, in accordance with the CIM Standards on Mineral Resources and Reserves. No current Pre-Feasibly Study or Feasibility Study has been completed for the Project, thus, no Mineral Reserves are reported.

This is a restricted disclosure as allowed under section 2.3(3) of NI 43-101 which includes a PEA and is preliminary in nature such that it includes a portion of the inferred mineral resources as reported in Section 14 of the report. The PEA is based on open pit mining and heap leach extraction of uranium values, utilizing methodologies, equipment, and a generalized design criterion which has been employed at the site and/or similar sites in the past but has not been specifically developed for the Project. Mineral resources are not mineral reserves and do not have demonstrated economic viability in accordance with CIM standards. Inferred mineral resources are too speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the outcomes estimated in the PEA will be realized.

The recommended base case for estimated mineral resources, as highlighted in the forgoing tabulation, is the 0.1 GT cutoff. This recommendation is based upon the author’s experience with successful open pit mining of similar deposits, including Maybell, Colorado and Gas Hills, Wyoming, which employed a similar cutoff criterion and the findings of the PEA.

The primary resource calculation method utilized in this report is the GT contour method which complies with the best practice guidelines specific to uranium for the estimation of mineral resources and mineral reserves adopted by the CIM November 23, 2003 and it is applicable to this type of deposit.

The mineral resource estimate represents a two dimensional estimate based on the total GT, by hole, meeting cutoff criteria. The cutoff criteria applied included: a minimum radiometric equivalent grade of 0.02% eU3O8, a minimum thickness of 2 feet to account for mine dilution, and a minimum GT of 0.10. Drill data reflecting the thickness (T), grade (eU3O.), and GT was summed for all intercepts meeting cutoff criteria by hole. GT and T were then contoured using standard algorithms based upon the geological interpretation of the deposit. From the contoured GT ranges, the contained pounds of uranium were calculated by multiplying the measured areas by GT and density. Similarly, the total tonnage was calculated by contouring thickness and multiplying by area to obtain cubic feet, then converting to tonnage by applying the density factor. Tonnage by GT range was estimated based on the ratio of GT areas to total tonnage and the results summed. A density factor of 16 cubic feet per ton was utilized in the mineral resource calculation. As discussed in Section 12, Data Verification, this factor is recommended by the author based on his direct mining experience in deposits of similar geologic age and genesis.

38


As stated in Section 10, Drilling, currently available drill data consists of: radiometric equivalent data (eU3O8) for 2,167 historic drill holes, radiometric equivalent data (eU3O8) and USAT assay data for 400 drill holes completed during the 2011 drilling program, and radiometric equivalent data (eU3O8) for 149 drill holes competed in 2012.

GT contour maps for Juniper Ridge East and West are provided as Figures 14.1 and 14.2, respectively. Due to the observed variability of grade, as previously discussed, the projection of mineralization for indicated mineral resources was limited to a maximum of 25 feet. Inferred mineral resources were projected up to 100 feet along interpreted mineralized trends. The spacing of drill data within the areas for which mineral resources are projected is generally 100 feet or less. Based on the density of data and interpretation of geologic continuity, the mineral resource, as calculated, is considered to meet CIM criteria as an indicated mineral resource.

Disequilibrium

Evaluation of radiometric equilibrium was based on 258 drill holes, with natural gamma and USAT data, completed in 2011 which met the cutoff criteria utilized in the mineral resource calculation. While the average disequilibrium factor was slightly less than 1 (0.94), the disequilibrium factor varies by area, ranging from 0.84 to 1.04 with the higher factors corresponding to the more highly mineralized areas of the deposit. For the purposes of assessing the overall mineral resources for the Project, it is recommended no correction for radiometric equilibrium be applied.

Figure 14.3 shows the general distribution of disequilibrium conditions with respect to the areas of project mineralization.

Environmental Permitting and Other Relevant Factors

With regard to the socioeconomic and political environment, Wyoming mines have produced over 200 million pounds of uranium from both conventional and ISR mine and mill operations. Production began in the early 1950’s and continuing to the present. The state has ranked as the number one US producer of uranium since 1994. Wyoming is generally favorable to mine developments provided established environmental regulations are met (refer to “Wyoming Politicians, Regulators Embrace Uranium Miners With Open Arms”, Finch, 2006).

Mine development would require a number of permits depending on the type and extent of development, the major permits being the mining permit issued by the State of Wyoming Department of Environmental Quality, Land Quality Division and the Plan of Operations approved by the BLM. Mineral processing for uranium would require a source materials license from the US Nuclear Regulatory Commission. To the author’s knowledge, these environmental permits have not been obtained. To obtain these permits, it is likely that an EIS would be required.

39


Portions of the project area are split estate which means that the surface ownership is held privately while the minerals are federal. In these areas, agreements with surface owners will be necessary for mining. Such agreements are currently in place for the drilling.

Within the general project area and vicinity oil and gas wells and infrastructure exist. Currently the oil and gas wells and infrastructure are not in conflict with the known mineral resource areas. As federal lands are subject to multiple uses, there is a risk that future oil and gas development and/or related infrastructure could be in conflict with mineral development.

To the author’s knowledge, there are no other significant factors that may affect access, title, or the right to perform work on the property.

Section 16– Mining Methods

16.1 Introduction

The PEA is based on open pit mining utilizing methodologies, equipment, and a generalized design criterion which has been employed at the site and similar sites in the past. Figure 16.1 depicts the overall conceptual mine layout. Conceptual mine designs were developed for three main areas. Mineral resources within the Juniper Ridge West area were incorporated in the MU pits. Mineral resources within the Juniper Ridge East area were incorporated in the PB or DC pits. Conceptual pit designs for the MU, PB, and DC areas are depicted in Figures 16.2 through 16.3, respectively.

16.2 Mineral Resources Used for PEA

This is a restricted disclosure as allowed under section 2.3(3) of NI 43-101 which includes a Preliminary Economic Evaluation (PEA). It is also preliminary in nature such that it includes portions of both indicated and inferred mineral resources, as reported in Section 14 of the report. The PEA is based on open pit mining and heap leach extraction of uranium values, utilizing methodologies, equipment, and a generalized design criterion which has been employed at the site and/or similar sites in the past but has not been specifically developed for the Project. Mineral resources are not mineral reserves and do not have demonstrated economic viability in accordance with CIM standards. Inferred mineral resources are too speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the outcomes estimated in the PEA will be realized.

The Indicated and Inferred Mineral Resources used in the PEA, Table 16.1, are fully included in the total Indicated and Inferred mineral resources reported in Section 14. They are that portion of the mineral resources which meet minimum cutoff criterion and are incorporated within conceptual mine designs, as further discussed herein. For conceptual mine design, mineral resources were subdivided into three main areas: PB, MU, and DC. The MU area corresponds with the Juniper Ridge West and the PB and DC areas correspond with the Juniper Ridge East.

16.3 Determination of Mine Cutoff Grade

Mineral resources were calculated based on a minimum mining thickness of 2 feet; a minimum grade of 0.02 % eU3O8; and a minimum GT of 0.10. Conceptual mine designs focused on the areas with the most extensive mineralization and sought to identify areas with stripping ratios less than 15:1, expressed as cubic yards stripped to pounds contained, and average diluted grade of 0.05% eU3O8 or greater. The PEA shows total direct operating costs of approximately $42 per ton and capital costs of approximately $10 per ton. Based on a commodity price of $65 per pound, the overall breakeven grade would be approximately 0.05% eU3O8 or a GT of 0.10. Marginal costs, including only direct mining and mineral processing, are estimated at $31.45 per ton. Mineralized material encountered below the mine GT cutoff, which has to be excavated as part of the mine plan and would otherwise be disposed of as mine waste, could be salvaged at grades as low as a calculated breakeven grade of 0.035 % U3O8 based on the marginal costs. This grade is slightly more than the minimum grade criteria.

16.4 Selection of Mining Method

The PEA is based on open pit mining utilizing methodologies, equipment, and a generalized design criterion which has been employed at the site and similar sites in the past. Open pit mining has two major facets: primary stripping or the removal of overburden and the mining of the mineralized material as it is exposed by the stripping. Primary stripping would operate a single 10 hour shift per day on a continuous basis with each operator working approximately 240 of 260 available days per year or 2,400 hours. Mining would be accomplished on a similar single daylight shift. If it were necessary to increase production, it is recommended that the mining remain a daylight operation for grade control purposes but the days and shifts be extended during the late spring to late fall when weather conditions are more favorable.

Grade control during both stripping and mining operations will be a critical aspect of the project. This type of sandstone hosted uranium deposit may exhibit local variability in grade and thickness, and potentially variable radiometric equilibrium conditions. Cost allowances have been made in the PEA for 4 fulltime grade control persons under direction of the mine geologist, along with the requisite field radiometric scanning and rapid assay equipment.

16.5 Conceptual Mine Design

The conceptual mine designs utilized a 0.6:1 (horizontal to vertical) slope. This allows for a highwall cut at a 0.5:1 slope with 10 foot wide safety benches incorporated at 50 foot vertical intervals. Highwall heights range from less than 40 to slightly more than 200 feet. The open pit design employs similar design parameters and mining equipment configurations to those used successfully in past Wyoming conventional mine operations. Ramps were not specifically incorporated in the designs at this level of study because the pits are quite shallow on the northern or up dip side and will not add significantly to the estimated excavation volumes. Minimum turn radii and travel widths were held to 100 feet.

46


16.6 Geotechnical Considerations

Specific geotechnical studies relating to highwall stability were completed historically, but no recent studies have been completed. There are remnant highwalls at the site from past mining which have stood at a 0.5:1 slope aspect for more than 50 years. At the relatively shallow depths planned, the author considers highwall design criteria utilized for the PEA to be adequate for the level of investigation.

16.7 Pre-Production Mine Development

Pre-production expenses relate primarily to project design and permitting and include:

Project Development and Design
o Drilling and Reserve Definition
o Mine Planning
o Metallurgical Testing
o Plant and Heap Design
o Property Holding Costs
Project Permitting and Licensing
o Environmental Baseline
o State and BLM Mine Plan and Plan of Operations
o NRC Source Materials License

In the PEA, an allowance of approximately 4.2 million $US was included over a four year period leading up to the year of capital construction prior to initial production. This was based on the author’s recent experience with similar projects.

16.8 Mine Equipment

Mining equipment is summarized in Table 16.2 and includes: the stripping and mining equipment, support equipment, facilities, and a 15% contingency.

The primary stripping equipment includes two 637 and two 631 scrapers which will work in pairs. The 637 scrapers being a twin engine push-pull scrapers and the 631 single engine scrapers. In the paired configuration, the scrapers will predominantly self-load but may at times be assisted by dozers.

Mining will be accomplished in a selective manner utilizing a 3 CY excavator and articulated mine haul trucks. This equipment would be capable of working in tight areas and selectively excavating mineralized material in lifts of 2 feet or less, as necessary. A 6 CY wheel loader is also included for handling of mined material at the stockpile and as a backup for the excavator.

The mining and stripping crews will be supported by dozers, a motor grader, and water trucks. While this configuration would be adequate for the Project, alternative equipment configurations could be considered.

16.9 Mine Productivity and Reclamation

Given the conceptual nature of the mine design, specific haulage profiles and/or cycle times were not determined. However, given the shallow nature and proximity of the pits cycle times in the range of 6 to 8 minutes (load, haul, dump, and return) were estimated. The annual production schedule and profile requires approximately 4 million CY of primary stripping annually. At cycle times of 6 to 8 minutes and allowing for 90% utilization, between 2.9 and 3.8 scrapers, respectively, would be required. The PEA conservatively assumed 4 scrapers on annual basis providing some additional excavation capacity.

The mining configuration including the excavator (with the loader as backup) and 4 haul trucks has sufficient capacity to mine over 400 thousand tons per year, handle up the same volume of internal waste, and haul the mined product to the heap facility.

The stripping equipment would also be utilized for mine reclamation and closure during cessation of operations. The PEA allows that the entire volume of the first pit in each area would be temporarily stockpiled at the beginning of the operation in each area. Subsequent pits would then sequentially backfill previous pits and the stockpiled mine waste from the first pits would be utilized to reclaim the final pits in each area.

Although it would be possible for the on-site equipment to also reclaim the heap and mineral processing facility, this was estimated as a contracted operation in the PEA. Reclamation of the heap and mineral processing facility would include dismantling of the facilities, on-site disposal, cover, and sloping of the reclaimed heap and plant site to a geomorphically stable configuration. A cost allowance of some 6.8 million $ US has been included in the estimate for an approximate 70 acre site.

16.10 Labor and Personnel Requirements

Labor requirements for staff and mine operations are summarized in Table 16.3. The total mine labor force is estimated at 35 including staff positions. Where positions are shown as halftime time in the table, it was assumed that one individual would serve dual roles and/or be shared with other operating facilities. Costs in the PEA allow for a year-round operation 5 days per week or 260 days per year. However, to account for lost days due to factors such a weather conditions operating productivity was based on 240 days.

Section 17 - Recovery Methods

17.1 Summary

The planned uranium recovery method at the Juniper Project is conventional heap leaching which includes: the mobilization of uranium into solution from the mined material stacked on the heap pad via acid leaching, delivery of uranium rich solutions to a recovery plant (mill), and concentration of the uranium via Ion Exchange (IX).

Uranium recovery at Juniper Ridge will include the following processes:

  • stacking of mined material on the heap leach pad;
  • application of leach solution;
  • collection of pregnant leach solution (PLS);
  • filtering of sand and fines from PLS;
  • IX to extract uranium from solution and load it on resin;
  • Shipment of the loaded resin to EFR’s White Mesa Mill for stripping, precipitation, washing, drying, packaging, storage, and loading as yellowcake.

The uranium recovery or “milling” process equipment will be housed in a single building within the proposed mill boundary. Loaded resin will be produced on-site. Yellowcake processing, including precipitation, washing, drying, packaging, storage, and loading, will be completed off-site. Reagent storage and distribution systems will be located within or next to the process buildings.

Processing (‘milling’) begins as run-of-mine product is crushed and then stacked on the double lined heap leach pad using covered belt conveyors and a covered radial arm stacking (RAS) belt . The stacked mined material is leveled with low ground pressure equipment forming a “lift”. A protective layer of gravel is place on top of the lift to mitigate fugitive dust and transport of radio-particulates from the heap. A drip irrigation system using conventional plastic piping is then installed on top of the completed lift, and the heap is ready for the application of leach solutions.

The general flow of solutions and uranium within the heap and recovery plant is as follows:

  • The process begins with the pumping of the refortified leach solution from the Barren Pond to the top of the heap where it is applied using drip emitters.
  • The leach solution consists of water; an oxidizing agent (sodium chlorate, to convert the uranium to the soluble hexavalent state), and a complexing agent (sulfuric acid) to complex and solubilize the uranium.
  • The result of the heap leach process is a pregnant leach solution (PLS) containing a mixture of uranyltrisulfate (UTS) and uranyldisulfate (UDS). PLS percolates through the stacked mined material via gravity drainage and is intercepted by the heap leach pad liner system and then gathered into collection pipes, which drain by gravity into the collection pond.

57


  • The PLS is then pumped from the collection pond into the IX plant where the PLS is filtered to remove suspended particulates, and the uranium is loaded on the resin.
  • The resulting uranium-depleted solution, called barren leach solution, flows by gravity from the IX plant to the barren pond. This barren solution is refortified with additional acid and oxidant and additional make-up water. It is then pumped back to the heap in a continuous cycle.
  • Resin is shipped from the plant to EFR’s White Mesa Mill for final processing to yellowcake.

17.2 Heap Leach and Plant Capital Requirements

Given the level of study of the PEA, specific heap leach pad and plant designs have not been completed. Equipment requirements, types, and sizes have been estimated based on typical design parameters tailored to the production profile of the Project. The PEA presumes that the heap would be constructed in a single lift of approximately 15-25 feet in height over an approximate area of 69 acres.

Capital costs related to the heap leach including crushing, conveying, stacking, and lined leach pads and ponds based on is estimated at 7.66 million dollars US (M$US). Capital requirements for plant and equipment is estimated at 8.59 M$US as summarized on Table 17.1. Thus, total capital cost for the plant and heap are estimated at $16.25 M$US.

Section 18 - Project Infrastructure

Access

The Project is located 6 to 10 miles west of Baggs, Wyoming and approximately 3 miles north of the Colorado-Wyoming border. (Refer to Figure 5.1 – Location and Access Map) The Project is accessible via two-wheel drive on existing county and two-track roads by proceeding one mile north of Baggs, Wyoming on Highway 789, then west on Carbon County Road 144 (Poison Buttes Road), towards Poison Buttes approximately 6 miles where the road crosses the Project for the next 4 miles. The site is generally accessible year-round.

Power and Utilities

Utility services including natural gas, electricity, and communications are located in Baggs, Wyoming 6 miles from the eastern boundary of the Project. Gas pipelines crossing the project area are shown on the base map.

Process Water

Detailed investigation of potential water sources has not been completed. Water supply could be obtained from locally permitted and constructed wells or from surface water sources including the Little Snake River approximately 3 miles south of the project area. Water rights for both surface and ground water are administered by the Wyoming State Engineer’s Office and are subject to prior water rights.

Mine Support Facilities

Mine support facilities will consist of an office, mine shop, and warehouse, and a dry facility. In consideration of the remoteness of the site and the potential for hazardous winter driving conditions, emergency stores of non-perishable food and water will be kept on-site along with portable cots, should it be necessary for personnel to remain on-site during such conditions.

Public Safety and Facility Maintenance

Access to the site will be controlled where appropriate. The mine facility will be regulated by MSHA. Any persons wishing to enter the facility will be required to complete safety training as required by regulations and be equipped with appropriate Personal Protective Equipment (PPE) depending on which areas they wish to enter. Access to the mineral processing facility and heap leach will be restricted in accordance with NRC regulations and license conditions. Once leaching is fully completed the spent material will be considered mill tailings and will be reclaimed in place in accordance with NRC regulations and license conditions.

Section 19 - Market Studies and Contracts

Uranium Market and Price

Uranium does not trade on the open market and many of the private sales contracts are not publically disclosed. Monthly long term industry average uranium prices based on the month-end prices are published by Ux Consulting, LLC, and Trade Tech.

As shown on Figure 19.1, the current spot price is less than the long term contract price. However, during periods when the spot price rises, such as the peaks in 2007 and 2011, the spot price equals or exceeds the long term price. Spot prices apply only to marginal trading and usually represent less than 20% of supply (World Nuclear Association, 2013). Thus, the author recommends use of long term uranium pricing in the PEA.

Thus, in a 5-year look-back from 2009 to the present, average uranium prices have been $47.37 per pound for spot delivery to $61.46 per pound for long-term delivery. More recently, in 2013, the average spot price was $38.07 and the average long-term price was $54.23. Near- to mid-term uncertainty has created recent weakness in uranium markets. The shutdown of reactors in Japan, building inventories, and a general lack of demand has been largely to blame for this near-term price weakness. However, longer-term market fundamentals in the uranium sector remain strong. Nations around the World, led by China, are building new nuclear reactors. Yet, current weakness in uranium prices is leading to new uranium projects being deferred or canceled. Indeed, the World Nuclear Association reports that there are now 70 nuclear reactors under construction around the World right now. In addition, Japan has signaled that it will restart many of their reactors in the coming years, with several potentially restarting in 2014. As a result, though predicting spot- and long-term prices is speculative, many analysts expect rising spot- and long-term prices in the coming years (Ux Consulting, 2013).

Ux Consulting Company, a leading source of consulting, data services and publications on the global nuclear fuel cycle markets, has published expected mid-range spot prices that average $70/lb. during the 10-year life of the Juniper Ridge Project, assuming production from 2018 to 2027. The Ux mid-point prices range from $55/lb. in 2017 to $77/lb. in 2025, (Ux consulting, 2013). However, Ux Consulting does not forecast prices beyond 2025. As a conservative estimate, the author has used $77/lb after 2025, the 11th year of the project, without escalation.

As a result, the author recommends utilizing a uranium price of $65/lb. as a base case in the PEA. The author believes this number is appropriate and conservative, as it is some 7% lower than the prices forecast by Ux Consulting.”

Section 20 - Environmental Studies, Permitting, and Social or Community Impact

Uranium mining at Juniper Ridge occurred from the mid-1950s through 1964 prior to the passage of either the Wyoming 1969 Open Cut Reclamation Act or the 1973 Wyoming Environmental Quality Act. A substantial amount of reclamation has since been performed at the property by mining companies and by the WDEQ/AML. WDEQ/AML can remediate hazard and reclaim mined lands which were disturbed prior to the passage of the federal Surface Mining Control and Reclamation Act of 1977.

The Juniper Ridge Project is situated on a mixture of private fee land with federal mineral rights, federal land and minerals administered by the BLM, and State Trust lands with state-owned minerals administered by the State of Wyoming.

Because of this mixture of land and mineral ownership and because the proposed mineral processing facility is licensed by NRC, a number of state and federal agencies are involved in the permitting and licensing of this project. WDEQ/LQD is the lead agency for the State of Wyoming, though other state agency approvals are necessary. The primary federal agencies involved include: the BLM, NRC and U.S. Environmental Protection Agency (EPA). In addition, County approvals for construction are also required.

BLM and Wyoming have established a Memorandum of Understanding (MOU) that allows WDEQ/LQD to issue the Mine Permit for both state and BLM lands while the BLM administers the National Environmental Policy Act (NEPA) for activities and impacts to the federal lands based on a Plan of Operations (POO) prepared by the permitee. The BLM also comments on the mining, milling, and reclamation activities proposed in the Mine Permit.

No potential social or community related requirements, negotiations, and/or agreements are known to exist with local communities and/or agencies other than those discussed herein.

The permitting and licensing requirements for this project, as discussed herein, are substantial as they are for any similar project in the US. To the author’s knowledge there are no identified environmental conditions that would materially affect the development of the project.

Environmental Studies

An Environmental Report was completed in the 1980s by Dames and Moore on behalf of AGIP Mining. To the author’s knowledge, this data is not available. Only limited environmental studies, relating primarily to drilling permits, have been completed recently on the Project.

Carbon County

Construction permits for buildings and septic systems will be required. The County permits are not anticipated to present technical or time critical issues in the development of the Project.

66


Wyoming Land Quality Division

A Mine Permit will be required by WDEQ/LQD. Under the MOU with BLM, WDEQ will formally approve the Mine Permit update after formal concurrence by BLM. No mine permit application has been submitted. Once the mine permit is granted bonding for the reclamation of the first year’s activities will be required. The bond is then updated annually to reflect reclamation requirements.

Wyoming Abandoned Mine Land Division

The WDEQ/AML program does not administer any licenses or permits directly related to the mining or milling activities. However, the AML program has completed mine land reclamation at the site in the past and has a current project to investigate remaining mine disturbance for possible future AML action.

Wyoming Air Quality Division

The Wyoming Air Quality Division (WAQD) administers the provisions of the Clean Air Act as delegated to the state by EPA Region VIII. No permit application has been submitted.

Wyoming Water Quality Division

Discharges to surface water, if needed as part of the mine dewatering and mine water management program, are permitted by the State of Wyoming under authority delegated by EPA Region VIII for the National Pollution Discharge Elimination System (NPDES) program. Currently, water produced from mine dewatering is expected to be 100-percent consumed for mineral processing and dust suppression. A WPDES permits application may be developed at a later date should the dewatering of the deeper underground levels produce more water than can be consumed by the mining and processing operations.

Wyoming State Engineers Office

The Wyoming State Engineers Office (SEO) is responsible for permitting of wells and impoundments, and issuance and modification to water rights. No permit applications relative to water rights have been submitted.

U.S. Bureau of Land Management

The BLM will require a Plan of Operations for mining in coordination with WDQ/LQD. BLM will likely require an EIS, separate from the NRC’s EIS and NEPA process. No applications have been submitted.

67


U.S. Nuclear Regulatory Commission

The NRC regulates source material within Wyoming and will require a Source Material License for the processing of uranium at the site. No application has been submitted. The NRC will require bonding for the estimated closure and reclamation of that portion of the site associated with the processing of uranium as defined in the Source Materials License.

U.S. Environmental Protection Agency

The EPA oversees compliance with 40 CFR Part 61 subpart W, radon emissions from tailings. No applications have been filed.

Social and Community Relations

Carbon County has a substantial mineral resource industry including coal mining and other minerals. Oil and Gas development is also prevalent in Carbon County and in the vicinity of the Project with wells and a gas pipeline within the general project area. The author is not aware of any specific social or community relations issues which would adversely affect the project.

Closure and Reclamation Plans

The land encompassing the Project area is currently used for livestock grazing, wildlife habitat, and recreation (primarily hunting). The reclamation plan will return the areas disturbed by the Project to the same pre-mining uses. Reclamation bonds will be in place prior to startup for both the mining and processing areas of the project, in accordance with state and federal requirements.

Solid and liquid wastes from the processing of uranium will be managed on site. Upon closure, liquid wastes will either be a) stabilized and placed in the spent heap leach pad or b) evaporated on the heap leach pad surface prior to closure. Process buildings and equipment that cannot be released from the site, will be decommissioned, sized, and then placed in the spent heap, according to NRC guidance. The heap leach pad and associated ponds will then be encapsulated within an engineered cover that is designed to minimize radon emissions and water infiltration. The disposal cell will then be monitored until the site meets DOE’s requirements for long-term stewardship.

68


Section 21 - Capital and Operating Costs

Project cost estimates are based on a conventional open pit mine operation with on-site heap leach extraction. It is anticipated that the project will not produce a final product, i.e., but will operate as a satellite facility for shipping loaded resin to another facility. For the PEA it was assumed that resin would be shipped to the planned EFR’s White Mesa.

All costs are estimated in constant 2013 US Dollars. Operating (OPEX) and Capital (CAPEX) costs reflect a full and complete operating cost going forward including all pre-production costs, permitting costs, mine costs, and complete reclamation and closure costs for of the mine. CAPEX does not include sunk costs or acquisition costs.

Mining and mineral recovery methods are described in Sections 16 and 17, respectively. The mine production profile is discussed in Section 16.11. Table 21.1 provides a summary of CAPEX.

Table 21.1: Capital Cost Summary ($ x 1,000)

Operating cost estimates are based on a conventional open pit mine with heap leach processing. Operating cost estimates were based upon vendor quotations, published mine costing data, and contractor quotations. Such estimates were generally provided for budgetary purposes and considered valid at the time the quotations were provided. In all cases, appropriate suppliers, manufacturers, tax authorities, smelters, and transportation companies should be consulted before substantial investments or commitments are made.

Operating costs were estimated for the following major items and are summarized on Table 21.2:

  • Mine Operating Expenses
  • Reclamation and Closure
  • Reclamation Bond
  • Taxes and Royalties
  • Transport of Resin to White Mesa
  • Allocated Costs for Final Processing at White Mesa

Note: The loaded resin could be shipped for final processing to other central processing facilities.

Section 22 – Economic Analysis

Financial evaluations that follow represent constant US dollars and a commodity price of $65.00 per pound of uranium as discussed in Section 19. As previously stated, all costs are forward looking and do not include any previous project expenditures or sunk costs. Operating costs include all direct taxes and royalties, as discussed in Section 21, but do not include US corporate income tax.

Estimation of US corporate income tax is difficult as income tax relates to the overall income and expenses of the reporting entity not a specific project. However, to evaluate the economics of the Juniper Ridge project, post corporate taxes, it was treated as a stand-alone project. This analysis reflects the most amount of taxes that would be due if the project alone were subject to U.S. income tax. Due to the favorable regular tax depletion deduction, most mining companies' effective tax rate is the Alternative Minimum Tax (AMT) rate. The regular tax percentage depletion deduction for uranium is equal to the lessor of 22% of gross revenue or 50% of taxable income after loss carry-forwards. In most cases, 50% of taxable income is less than 22% of gross revenue. Thus, the percentage depletion deduction is equal to 50% of taxable income which reduces the effective regular federal tax rate from 35% to 17.5% . As the AMT rate is 20% and a taxpayer is subject to the larger of AMT or Regular tax, the AMT rate of 20% becomes the effective rate. The Juniper Ridge property is located in WY which has no state income tax so the combined Federal and state rate remains at 20%. (Beck, 2014)

It is likely however that the actual amount of cash taxes paid as a result of this project would be significantly less than the 20% AMT rate due to the following:

  • Juniper Ridge is included in the Strathmore Resources (US) Ltd. corporate income tax return which has loss carry-forwards available to offset future income.
  • Strathmore Resources (US) Ltd. may generate additional losses during the time frame of this model (2014-2030) from other development projects that produce losses that would be net against the income from Juniper Ridge.
  • In addition, head office/general and administrative costs would be allocated to the project as part of a complete legal entity tax return and would reduce the actual cash taxes paid.

Net Present Value (NPV) is calculated at a range of discount rates as shown both pre and post US corporate federal income tax. Table 22.1 summarizes the pre and post corporate income tax estimated internal rate of return (IRR) and net present value (NPV). Subsequent sensitivity analysis is provided for commodity price and other factors and was completed as a pre-tax analysis although the relative sensitivity would be similar for post-tax. Detailed Cash Flow analysis is provided in Table 22.4 at the end of this section.

Sensitivity to Other Factors

Sensitivity of the projected IRR and NPV, with respect to key parameters other than price as previously shown, is summarized in Table 22.3. The sensitivity analysis shows that the project is not highly sensitive to minor changes in OPEX and/or CAPEX. With respect to mine recovery and process recovery, the sensitivity is similar to that of uranium price in that much of the same costs are incurred and any variance in mine recovery affects gross revenues either positively or negatively. The project is roughly twice as sensitive to variances in mine recovery and/or process recovery as it is to variance in OPEX or CAPEX.

Mine recovery is highly dependent upon grade control and mining selectivity. The mine plan, equipment selection, and personnel allocations included in the cost estimate provide for selective mining and tight grade control in recognition of this factor.

Process Recovery is based on a loss of 0.01 % U3O8 (including solid and liquid losses). This yields an average percent recovery of 84.5% which is conservative in comparison to historic data as summarized in Section 13.

Payback Period

Capital investment was assumed to begin three years prior to startup to include such items as: exploratory drilling, environmental baseline studies, engineering and design related studies, and permitting and licensing. Once in operation the Project has a positive cumulative cash flow three years after the project startup, in constant dollars, refer to Table 22.4, Cash Flow.

Cautionary Note:

This is a restricted disclosure as allowed under section 2.3(3) of NI 43-101 which includes a PEA. It is preliminary in nature in that it includes a portion of the inferred mineral resources, as reported in Section 14 of the report. The PEA is based on open pit mining and heap leach extraction of uranium values, utilizing methodologies, equipment, and a generalized design criterion which has been employed at the site and/or similar sites in the past but has not been specifically developed for the Project. Mineral resources are not mineral reserves and do not have demonstrated economic viability, in accordance with CIM standards. Inferred mineral resources are too speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the outcomes estimated in the PEA will be realized.

Section 23 – Adjacent Properties

The nearest and most similar adjacent property is the Maybell/Lay area located approximately 36 air miles (55 road miles) SSW near the community of Maybell, Colorado. Uranium mineralization is hosted in the Browns Park Formation. The genesis of uranium mineralization at Maybell is very similar to that of the mineralization found at Juniper Ridge (Vine and Prichard, 1954).

Mining in the Maybell area was conducted using open pit methods by Trace Elements Corporation who was later acquired by UCC. The uranium mill at Maybell was operated under an AEC uranium concentrate purchase contract executed November 5, 1956. The Maybell mill facility was shut down in October, 1964 and decommissioned (Albretsen and McGinley 1982). Subsequently, the facility was re-opened for a brief period in the late 1976 and operated through1981 as heap leach facility processing low grade mineralized stockpiles and newly mined material. The heap leach facility used acid leach with solvent extraction, producing a uranium rich resin which was shipped to UCC’s Gas Hills, Wyoming facility for final beneficiation (personal knowledge of the author employed by UCC at the time).

The Maybell mill processed some 2.3 million tons of material containing 4.57 million pounds of uranium at an average grade of 0.098% U3O8. The facility recovered just over 4 million pounds of uranium (Albretsen and McGinley 1982). The heap leach facility produced approximately 1 million additional pounds of uranium. (Personal knowledge of the author employed by UCC during the time of this operation as a staff member of the Gas Hill operations to which the Maybell heap leach facility was a tributary operation.)

 Mineral claims in the Maybell area are currently held by Oregon Energy a US subsidiary of Energy Ventures of Australia. (http://www.energyventures.com.au/projects/projectsoregon.html)

Section 24 – Other Relevant Data and Information

Molybdenum is known to be associated with the uranium mineralization at Juniper Ridge. Earlier studies (Pincock, Allen, & Holt, 1978) included recovery of molybdenum as a co-product. Later studies (Pincock, Allen, & Holt, 1986) did not. Whether molybdenum is recovered as a co-product or not, due consideration should be given to its presence, with respect to process design, as it may affect uranium recovery under certain circumstances. Most of the historic assay data with respect to molybdenum concentrations is not available. It is recommended that whenever physical samples are analyzed for uranium, analysis for other constituents including molybdenum, selenium, arsenic, and carbonates be completed. The presence or absence of these constituents may have implications for process design and/or tailings management.

Substantial data was once developed with respect to ground water conditions. Currently available data and reports have very little information in this regard. Based on the author’s personal work experience on the Project, the water table is relatively shallow, less than 100 feet from the surface. The Browns Park Formation is a single unconfined aquifer with low permeability and transmissivity due to the interstitial clay content. Water quality generally meets Wyoming standards for livestock but does not meet drinking water standards. Additional and current data relative to ground water conditions, water levels, water quality, and flow rates is needed for project design and ultimate environmental permitting. To the extent possible, a zero discharge facility should be considered in the design process.

Within and adjacent to the Project, there is oil and gas development. Oil and gas are leasable commodities whose rights are independent of the uranium mineral rights, which are locatable under US laws and regulations. While neither mineral should preclude the development of the other, the presence of the oil and gas development may limit access and/or impact activities such as ground water monitoring. It is recommended that the oil and gas lessees be contacted as to potential conflicts and to gain a full understanding of their processes, as they may affect environmental baseline and monitoring programs. Oil and gas development in the vicinity of the Project is at depths in excess of 2,500 feet in geologic formations separate from the Browns Park. Search of the Wyoming Oil and Gas Commission website (http://wogccms.state.wy.us/) shows one well with log data located in the SE, SW of Section 28, Township 13 North, Range 92 West. This well, North Gamblers Fed 30-28, was completed to a depth of 8,700 feet and targeted potential oil and gas in the Fort Union, Lance, Fox Hills, and Lewis Shale formations. Other shallower wells are located in the vicinity, but no log data is available.

Section 25 – Interpretation and Conclusions

Based on density of drilling and verification drilling completed in 2011 and 2012, the mineral resource estimate meets the criteria for either Indicated Mineral Resources, as shown in Table 1.1, or Inferred Mineral Resources, as shown on Table 1.2, in accordance with the CIM Standards on Mineral Resources and Reserves. No current Pre-Feasibility Study or Feasibility Study has been completed for the Project. Thus, no Mineral Reserves are stated.

The base case for the PEA considers open pit mining in conjunction with on-site heap leach processing, producing an intermediate uranium concentrate in the form of loaded resin which would then be shipped to EFR’s White Mesa mill for final processing. Given the assumptions described herein, the PEA demonstrates a positive return on investment. Further studies may also consider alternatives of on-site upgrading with off-site processing.

This is a restricted disclosure as allowed under section 2.3(3) of NI 43-101 which includes a PEA and is preliminary in nature, such that it includes a portion of the inferred mineral resources as reported in Section 14 of the report. The PEA is based on open pit mining and heap leach extraction of uranium values, utilizing methodologies, equipment, and a generalized design criterion which has been employed at the site and/or similar sites in the past but has not been specifically developed for the Project. Mineral resources are not mineral reserves and do not have demonstrated economic viability in accordance with CIM standards. Inferred mineral resources are too speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the outcomes estimated in the PEA will be realized.

Substantial data was once developed for previous technical studies and environmental permitting and licensing. Some of this data has been recovered. It may be used for reference and to guide the future studies and work programs recommended in Section 26 of this report. If more of the historic data can be located, this could diminish the level of future studies, provided the data and/or conclusions of such historic data and information is properly verified and confirmed.

The Project is located in an area which has been mined in the past. To the author’s knowledge, there are no conditions of a political or environmental nature that would preclude the development of the Project, provided that all applicable state and federal regulations are met.

The author is not aware of any other specific risks or uncertainties that might significantly affect the mineral resource estimates. Any estimation or reference to costs and uranium prices within the context of this report over the potential life of mine are by its nature forward-looking and subject to various risks and uncertainties. No forward-looking statement can be guaranteed and actual future results may vary materially.

Section 26 - Recommendations

Recommendations are broadly divided into the following major categories: drilling, metallurgical studies, preliminary feasibility studies, and baseline studies. The major categories are generally listed in order of importance although some studies need to be completed, all or partially for other studies to proceed. The recommendations that follow should be amended based on the results of other studies.

Drilling

Drilling costs are estimated at $10 per foot based rates to include: drilling, geophysical logging, supervision, and overhead. The drilling is shown by area in the following table with general areas shown on Figure 26.1. Historic drill maps should be used to guide the drilling program.

Expense Category Scope of Services Estimated Cost
Exploratory Drilling North Trend - 100 holes; 16,000 feet. $160,000
  North East Trend - 25 holes; 4,000 feet $40,000
Delineation Drilling Confirmation and delineation Juniper Ridge West 25 holes; 4,000 feet $40,000
  Main Resource Area - 200 holes; 32,000 feet. $320,000
Total Estimated Cost 350 holes; 56,000 feet $560,000

Metallurgical Studies

Metallurgical studies utilizing representative core samples from the 2011 drilling program should evaluate both acid and alkaline lixiviants. The studies should not be limited only to resource recovery, but should characterize both liquid and solid waste streams. The disposal/containment costs and environmental sensitivities of mill tailings are such that it is critical to characterize the potential waste streams as to their physical and chemical characteristics. Studies should also evaluate alternatives for stabilizing the waste streams physically and/or chemically. In addition, the nature of the mineralized material is such that the uranium values primarily occur as interstitial filling around the sand grains. As such, various techniques for mechanically upgrading the material may be considered. For all methods tested for the upgrading of the mineralized material, mass balance for uranium, associated metals, and carbonates should be determined.

Expense Category Scope of Services Estimated Cost
Leach Studies Complete a range of leach conditions beginning with data from previous work. Six tests each alkaline and acid including analytical work. $15,000
Column Leach Testing Minimum of two columns based on selected conditions from leach studies $30,000

Size Fraction Testing Standard sieve analysis; ¼ inch minus to 400 mesh screening. Mass balance for uranium, associated metals, and carbonates. $5,000
Attrition Scrubbing Four tests attrition test and analysis $8,000

78



Ablation Four tests at a ranging of liquid/solid ratios $20,000
Gravity Separation Four tests with mass balance for uranium, associated metals, and carbonates. $4,000
Flotation Four test with mass balance for uranium, associated metals, and carbonates. $4,000
Waste Characterization Determine general engineering and chemical properties of waste products. Develop samples for diffusion testing. $12,000
Waste Diffusion Testing ASTM C 1308 testing of tailings samples to determine long term diffusion rates of potential contaminants. Four tests. $28,000
Total Estimated Cost   $126,000

Preliminary Feasibility Studies

A summary of major tasks for completion of a preliminary feasibility study follows. It is recommended that the base case should be an open pit mine operation in conjunction with an on-site heap leach mineral processing facility.

Expense Category Scope of Services Estimated Cost
Open Pit Mine Conceptual Design and Sequence Prepare conceptual open pit designs and mine sequence. Evaluate production options of 250 to 500 thousand pounds per year. $50,000
Mine CAPEX and OPEX Estimate capital and operating costs based on similar project experience and published mine cost data. $20,000
Mineral Processing Facility Preliminary Design Conduct confirmatory leach testing for alkaline and acid lixiviant. Prepare conceptual design for on-site heap leach. Address conventional milling and off-site processing as alternatives. $50,000
Mineral Processing CAPEX and OPEX Estimate capital and operating costs based on similar project experience and published mine cost data. $20,000

Baseline Studies

Although baseline studies are not typically completed until the Project is in the environmental permitting process, there are advantages to initiating and/or completing certain studies. Completion of both wildlife and archeological studies is recommended. Completion of these studies will assist with permitting of the current drilling program and future permitting needs. In addition, collection of limited ground water level and quality data will aid future permitting because a minimum of one year baseline data is required in this regard.

APPENDIX B – USAT LOGGING


 


Uranium Calibration Facility

Calibration of the tool was carried out at the Grand Junction, Colorado – Uranium Calibration facility. The selected test pits that were utilized for the calibration gives a range from 0.027 to 2.415 percent uranium. The following test pits were used and the chemical grade assignment to the pit was used in the analysis.

Test Pit Assigned Grade in %
   
A1 0.027
A2 0.072
A3 0.155
U3 0.481
U2 1.233
U1 2.415
   
   
   
   
  Logging of the A Pits.

 

The data was then plotted and a polynomial curve fit for the grade verses CPS was developed, showing a correlation of 0.999. Repeat logging of the was incorporated to assure accuracy and quality of the data. Equivalent grades as recorded by the tool are the following:

Test Pit USAT Grade in %
   
A1 0.025
A2 0.072
A3 0.154
U3 0.423
U2 1.241
