SECTION 3                     SUMMARY

The following report was prepared by BRS Inc. a Professional Engineering and Natural Resource Corporation duly licensed in the State of Wyoming, USA. The report addresses the geology, uranium mineralization and in-place mineral resources of the mineral holdings of Energy Metals Corporation (EMC) located in Sections 19 and 30, Township 34 North, Range 72 West, Sections 14, 23, 25-27, and 34-36, Township 34 North, Range 73 West and Sections 1 and 2, Township 33 North, Range 73 West. Approximate Latitude 40o 35’ North and Longitude 105o 52’ West. The property being referred to as the Peterson Uranium Project is located in Converse County Wyoming approximately 36 air miles east of Casper, Wyoming (refer to Figure 1, Location Map) and consists of 139 unpatented mining lode claims and one State lease area, comprising some 3,269 acres.

This report is a summary of mineral resources. Although historical metallurgical reports and mineral reserve estimates are available for this property that indicate the property is amenable to insitu mining, that level of study is beyond the current scope of this report. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

The Peterson Uranium Project was extensively explored during the 1970’s through the early 1980’s with the principal exploratory work and drilling completed by Nuclear Assurance Company (NAC) on behalf of Arizona Public Service Company (APS) and Malapai Resource Company. The data utilized in this report consists of drill logs generally containing gamma, resistivity, and spontaneous potential, from 1,671 rotary drill holes (1,458 on EMC’s current holdings) and 29 diamond core holes. Mineral resource estimates are based on radiometric equivalent uranium grade as measured by the geophysical logs and correlated with chemical assay data from core drilling.

The host formation for known mineralization at the site is the “B”, “C”, and “D” sands of the Paleocene Fort Union Formation. Locally the Fort Union is a medium to coarse grained arkosic sandstone with local conglomeritic zones grading upward to thinner interbedded sandstones, siltstones, mudstone, carbonaceous shales, and coals.

Uranium mineralization at the Peterson Uranium Project is typical of the Wyoming Sandstone Roll-Front mineralization. Historical drilling on the lands currently held by EMC defines the mineralized trend within the three sand units in the upper Fort Union. Drilling in these areas is of sufficient density to classify the mineralization present as measured or indicated mineral resources depending on continuity of the specific mineralized zone.

Recommendations for the continuing exploration and development of this mineralization include:

  1.

Confirm previous metallurgical studies and investigations including the collection of additional core samples for testing.

4



  2.

Confirm previous hydrological investigation and studies including verification of pump test data and determination of current ground water levels and quality.

  3.

Complete a mineral reserve and economic feasibility study including preparation of a 43-101 compliant mineral reserve report.

  4.

For future assessments of mineral reserves additional data relative to radiometric equilibrium should be developed and equilibrium be evaluated for each mineralized zone rather than for the mineralization as a whole.

  5.

Historic data from the L claims should be obtained if possible. In the event such data is not available the area should be evaluated by drilling.

  6.

Determine the potential for developing the property as a satellite operation feeding existing facilities in the area and/or consolidating this property with other properties in the vicinity to support the capital investment of a new central processing facility.

No economic evaluation of the mineralization described herein was completed. Thus, the estimate that follows is solely a mineral resource estimate. Previous estimates assumed mining by ISL methods and estimated the average grade of the mineralization to range from 0.061 %eU3O8 to 0.118 %eU3O8 depending upon thickness and grade cutoff criteria.

Historical mineral resource estimates for the Peterson Uranium Project have been released by Energy Metals Corporation. Refer to energy Metals Corporation News Release 18 dated Tuesday August 5, 2005.

The current mineral resource estimate follows:

SECTION 4                     INTRODUCTION AND TERMS OF REFERENCE

This report was prepared by BRS Inc. for EMC to address the geology, uranium mineralization and in-place mineral resources within EMC’s mineral holdings known as the Peterson Uranium Project. The Peterson Uranium Project was extensively explored during the 1970’s through the early 1980’s with the principal exploratory work and drilling completed by Nuclear Assurance Company on behalf of Arizona Public Service Company (APS) and Malapai Resource Company.

The data utilized as the basis of this evaluation and in the preparation of this report was acquired by EMC from Cogema Mining, a subsidiary of Areva Group. No additional drilling was completed on the property. The data utilized in this report consists of drill logs generally containing gamma, resistivity, and spontaneous potential, from 1,671 rotary drill holes (1,458 on EMC’s current holdings) and 29 diamond core holes.

The author is a Professional Geologist licensed in Wyoming and Professional Engineer licensed in Wyoming, Colorado, Utah, and Oregon and a Registered Member of the US Society of Mining Engineers (SME). The author is experienced with uranium exploration and development and uranium mining including past employment with the Homestake Mining Company, Union Carbide Mining and Metals Division, and AGIP Mining USA. As a consultant and principal engineer of BRS Inc., the author has provided geological and engineer services relative to the development of mining permits for ISL operations in the Gas Hills and Powder River Basin. This experience spans a period of over thirty years dating back to 1974.

The author visited the site in the past while working as a consultant to a previous mineral owner and is familiar with the physiography and local geology of the area. On June 26, 2006, the author conducted field work on the site, inventorying existing wells and verifying current water levels. The principal well for the proposed ISL test site, OW9, was intact, however, other wells in the immediate vicinity had been plugged and abandoned. The current water level in OW9 was 127.6 feet below the ground surface. Past water level measurements from The Wyoming State Engineer’s Office (SEO) include 125 feet measured on August 16, 1979 and 125.9 feet measured on July 7, 1988. Thus, water levels have remained essentially unchanged since the well was originally installed on the property.

SECTION 5                     RELIANCE ON OTHER EXPERTS

The author has relied on the accuracy of the historical data as itemized in Section 4 and various project reports as referenced in Section 23 of this report.

The location of the unpatented mining lode claims, shown of Figures 2 & 3, which form the basis of the mineral holdings, was provided by EMC and was relied upon as defining the mineral holdings of EMC in the development of this report.

SECTION 6                     PROPERTY DESCRIPTION AND LOCATION

The Peterson Uranium Project is located in Sections 19 and 30, Township 34 North, Range 72 West, Sections 14, 23, 25-27, and 34-36, Township 34 North, Range 73 West and Sections 1 and 2, Township 33 North, Range 73 West approximately 36 air miles east of Casper, Wyoming (refer to Figure 1, Peterson Uranium Project Location Map). Approximate Latitude 40o 35’ North and Longitude 105o 52’ West

The Peterson Uranium Project Claim Maps, Figures 2 & 3, were provided by EMC and represent the approximate location of unpatented mining lode claims held by EMC. The mining claims are unpatented mining lode claims and along with one state lease, in total comprise some 3,269 acres. The land surface consists of both private and state lands. EMC controls three claim blocks referred to as PAR claims, L claims, and GL claims, and a State of Wyoming lease as follows:

Property Township Range Section(s) No. Claims ~ Acreage
PAR 34N 73W 29, 30, 31, 32 89 1,745
GL 34N 72W 19, 30 38 661
L 34N 73W 14, 23 12 219
Section 36 34N 73W 36 NA 644
TOTAL         3,269

The claims were located by EMC and are not known to have any encumbrances or royalties. The claims will remain the property of EMC provided they adhere to required filing and annual payment requirements with Converse County and the Bureau of Land Management (BLM). Legal surveys of unpatented claims are not required and to the author’s knowledge have not been completed. In addition to these mineral holdings EMC has filed the following Notices of Intent to Locate (NOITLs):

  • WYW 172907 – T34N, R73W, Section 24, N ½ SE ¼
  • WYW 173072 – T34N, R73W, Section 25, SW ¼, Section 26 N ½ SE ¼, Section 35 S ½, SW ¼

There are no pre-existing mining and/or mineral processing facilities or related wastes on the property. In order to conduct exploratory drilling of the property, the operator will be required to obtain permits (License to Explore) from the State of Wyoming Department of Environmental Quality. Land Quality Division, (WDEQ/LQD) and mine development would require a number of permits depending on the type and extent of development, the major permit being the actual mining permit issued by the WDEQ/LQD. Mineral processing for uranium would require a source materials license from the US Nuclear Regulatory Commission (USNRC). To the author’s knowledge, there are no current environmental permits for the project area. However, according to a November 1, 1985 report by the Malapai Resources Company, the project at that time held a WDEQ/LQD permit for a research and development (R&D) operation and an USNRC source Materials License. To the author’s knowledge, the R&D pilot was not constructed or operated.

SECTION 7                     ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE, AND PHYSIOGRAPHY

The Peterson Uranium Project is located within the Wyoming Basin physiographic province in the south portion of the Powder River Basin. The site is near the Deep Basinal Axis. Regional structural features also include the Laramie Mountains to the south, Casper Arch to the west, and the Black Hills and Hartville Uplift to the east.

The site is located at approximately Latitude 40o 35’ North and Longitude 105o 52’ West in the southern end of the Powder River Basin and within the drainage basin of the North Platte River which lies approximately 1 mile south of the project. The area is a low lying plain, roughly 5,000 feet in elevation. Vegetation is characteristically sagebrush and grassland. Historically the land has been used for livestock grazing. PRI’s Highland Uranium ISL operation is located approximately 14 miles to the northwest. Teton Minerals conducted an ISL pilot operation at the Leuenberger Project approximately 4 miles to the west. Conventional mining was conducted in the Box Creek District less than 10 miles north of the project.

The site is accessible via 2-wheel drive via two different routes. From Casper take I-25 east and at Glenrock turn north onto Highway 95 and continue to the junction of Highway 95 and 93. At this junction turn right onto Highway 93 and travel southeast ~6 miles to the site. Alternatively, from Douglas take Highway 93 northwest ~10 miles.

SECTION 8                     HISTORY

Peterson, et al, conducted the initial exploration and drilling program on the property. Arizona Public Service Company (APS) acquired an option on the property in 1978 and retained the Nuclear Assurance Company (NAC) to conduct drilling and feasibility studies on the property. The feasibility report was completed in 1979. Additional development drilling was completed by Malapai Resources in performance of annual claim assessment work at least through 1986. Of the total drilling completed in the vicinity data from 1,671 rotary drill holes and 29 diamond core holes were available for this study. From this database 1,458 rotary drill holes and the 29 diamond core holes are located within EMC’s current mineral holding. The mineral resource estimate contained herein was based on 786 mineralized holes of which 645 contained mineralization in excess of the minimum GT cutoff.

Drill hole locations are shown on Figures 2 and 3, Peterson Uranium Project Drill Holes PAR Claims, and Peterson Uranium Project Drill Holes L and GL Claims, respectively. The drill maps show the collar locations. All drilling was vertical. Downhole drift was surveyed in conjunction with geophysical logging. Review of the reported drifts showed the downhole drift to be random and generally less than five feet. This is typical and does not effect the mineral resource evaluation. Drill hole maps were created from original drill hole location listings, digitally rectified to state plane coordinates and then compared to historic drill maps for accuracy.

Historic mineral resource estimates by Malapai Resources Company were based on a 4 foot of 0.03 %eU3O8 or a GT of 0.12 and are comparable to the current estimate.

Uranium mineral resources within and adjacent to the project are found in the upper portions of the Paleocene Fort Union Formation. The Fort Union Formation is a fluvial sedimentary stratigraphic unit consisting of fine to coarse grained arkosic sandstone which is interbedded with siltstone, mudstone, and carbonaceous material. The coals mined in the Powder River Basin are also in the Fort Union Formation and are being mined some 20 miles to the west at the Glenrock Coal Mine and at numerous mines 40 miles or more north of the project. The Fort Union formation overlies the Cretaceous Lance Formation, a dominantly marine sedimentary formation. Regionally the Fort Union is overlain by the Tertiary Wasatch Formation, however, within the project area the Wasatch is not present and the Fort Union or younger Quaternary alluvial deposits are exposed at the surface (refer to Figure 4).

Locally, Malapai (APS) designated the host sandstone units beginning with the shallowest as the “B”, “C”, and “D” sands. The thickness of these dominantly sandstone units vary from twenty to forty feet and they are separated by approximately 30 foot thick mudstone units that confine the sandstones. Mineralization defined by drilling ranges in depth from approximately 140 to 300 feet. The formation dips slightly basinward in place less than 1 degree but averaging 2-3 degrees.

The Malapai terminology was observed in the preparation of this report for consistency.

SECTION 10                     DEPOSIT TYPES

Uranium mineralization at the Peterson Uranium Project is typical of the Wyoming Sandstone Roll-Front mineralization as described by Ganger and Warren (1979), Rackley and others (1972), and Davis (1969). Davis describes known uranium mineralization in the Powder River Basin as being “usually multiple ‘C’-shaped rolls distorted by variations in the gross lithology. The individual rolls range in thickness from two to 20 feet and may be several thousand feet in length.”

Figure 5 is a schematic of a typical roll front based on interpreted drill data from the project.

12


SECTION 11                     MINERALIZATION

Please note the following terminology is used in this report:

  1.

GT is the grade thickness product.

  2.

Grade is expressed as weight percent.

  3.

eU3O8 means radiometric equivalent U3O8.

EMC’s mineral holdings include portions of Sections 19 and 30, Township 34 North, Range 72 West, Sections 14, 23, 25-27, and 34-36, Township 34 North, Range 73 West and Sections 1 and 2, Township 33 North, Range 73 West. Drill data from 1,731 drill holes is available. Of the total drilling completed in the vicinity, 1,458 rotary drill holes and 29 diamond core holes are located within EMC’s current mineral holding. The mineral resource estimate contained herein was based on 786 mineralized holes of which 645 contained mineralization in excess of the minimum GT cutoff. A description of the basic parameters of the mineralization follows.

Mineralization Thickness

Mineralized thickness ranges from 1 foot to over 20 feet with an average thickness of mineralization, above 0.02% eU3O8, of approximately 8 feet.

Grade

Grade based on radiometric equivalent weight percent U3O8, eU3O8, ranges from 0.02 to 1.039 %eU3O8. Average grade is dependent upon cutoff assumptions. Mineral resource estimates, discussed in Section 19 of this report, were completed by contouring the Grade Thickness, GT. At GT cutoffs ranging from 0.10 to 0.50 average grade varies from 0.074 to 0.113 % eU3O8.

Width

At a GT cutoff of 0.25, the width of individual roll fronts varies from 30 to in excess of 200 feet with an average of approximately 80 feet.

Trend Length

PAR Claims, Sec 25-27 & 34-36 T34N R73W and Sec 1 & 2 T33N R73W

Drilling in Sections 26 and 34-36 is sufficient to define a mineralized trend along a trend length of approximately 34,600 feet within the B, C, D1 and D2 sands Trend lengths by sand units are B Sand 16,900; C Sand 9,600; D Sand 8,100 feet. The sand thickness of these zones is twenty to forty feet and they are separated by approximately thirty feet of mudstone. Mineralization ranges from 180 to 300 feet in depth depending on the sand unit and the surface elevation.

13


GL Claims Sec. 19 T34N R72W

Mineralization in Section 19, T34N, R72W, is limited to the southwest corner of the section. The hole spacing is located within approximately 100 feet along trend and 50 feet perpendicular to trend and mineralization appears continuous. Based on drilling, a total trend of approximately 12,300 feet can be projected for the B and C sand units with 3,100 feet of trend in the B sand and 9,200 feet in the C sand. Mineralization ranges from 180 to 290 feet in depth depending on the sand unit and the surface elevation.

L Claims Sections 14 and 23 T34N R73W

Current data does not define appreciable mineralization in Section 14 and 23, T34N, R73W. Historical data indicates the presence of mineralized trends on this property but at this time the historical data is not available.

Summary

As is typical for roll-front mineralization, grade, thickness, and width are expected to vary along the trend. The interpreted mineralized trend, shown on Figures 10 and 11 is based on drill data. Given the density of drill data and based on the continuity of each mineralized horizon, the mineral resource estimate, herein, meets the criteria as either measured or indicated mineral resources under the CIM Standards on Mineral Resources and Reserves depending on the continuity of each specific mineralized horizon.

14


SECTION 12                     EXPLORATION

Data available for the preparation of this report is historic data developed by previous owners of the property. EMC has not yet conducted its own exploration of the property. The relevant exploration data for the current property is the drill data as previously discussed and as represented graphically in the various figures of this report. This data demonstrates that mineralization is present on the property and defines its three dimensional location. The drill data is dominantly based on interpretation of downhole geophysical logs typically consisting of natural gamma, resistivity, and SP (Spontaneous Potential). Resistivity and SP were utilized for defining lithology and correlating the logs (Refer to Figures 6 through 9 for geologic cross sections). Geophysical logging was dominantly provided from a commercial vendor, Century Geophysical. Calibration of the logging trucks was routinely conducted at Department of Energy facilities. Data in the possession of EMC includes the original geophysical logs, a log interpretation calculation sheet for each drill hole, and a lithologic log for each drill hole.

The author has completed such training in the interpretation of geophysical logging data and received certification of same on November 19, 1976 from the Century Geophysical Corporation. The author reviewed the log interpretations from numerous drill holes. The data is considered reliable.

Also, include in EMC’s database are the results of chemical analysis from 29 core holes including copies of commercial laboratory certificates. This data was reviewed and was the basis of the evaluation of equilibrium conditions provided in Section 20 of this report.

15


SECTION 13                     DRILLING

Drilling was dominantly rotary drilling with only 29 core holes completed on the property for confirmation of radiometric equilibrium. Radiometric equilibrium is assumed for this property based on geologic factors and the available data and is discussed in Section 20.

The dip of the host formation is approximately 2-3 degrees to the northeast. Drilling was conducted vertically. Drift was measured by geophysical logging units and was random with maximum horizontal deviation less than 5 feet. This slight variation from vertical does not impact interpreted mineralized thickness nor does the slight variation in horizontal location impact the mineral resource estimate.

Data available for the preparation of this report is historic data developed by previous owners of the property. EMC has not yet conducted its own exploration of the property.

16


SECTION 14                     SAMPLING METHOD AND APPROACH

As previously discussed in Section 13, standard methods of the industry were utilized at the time of data collection. Original geophysical and lithologic logs, downhole drift surveys, and a listing of survey data for both the collar location is available for the majority of the drill holes. Core and/or drill samples are not available for review. The data for this project has been well preserved and is considered reliable.

17


SECTION 15                     SAMPLE PREPARATION, ANALYSES, AND SECURITY

The radiometric data from geophysical logs was provided by an independent commercial vendor. Instrumentation used was calibrated at Department of Energy facilities designed and built for that purpose. Geophysical log interpretations were reviewed. The log interpretations followed standard methods and protocol.

Core and/or drill samples are not available, however, original lithologic logs and copies of commercial laboratory certificates for chemical analysis of cores are available.

18


SECTION 16                     DATA VERIFICATION

The original radiometric drill data was available as a paper record. This data was input as electronic data via a spreadsheet into the computer programs utilized in the development of this report. Data entry was checked and confirmed. Drill hole locations were input from coordinate listings and plotted. The resultant drill maps were then checked and confirmed by overlaying with the original maps. Radiometric log interpretation was spot checked by the author for the higher grade intercepts and as previously discussed the historic log interpretation followed standard methods.

For ISL operations it is critical that the mineralization be below the water table. Existing hydrologic data was available from APS reports. To confirm this data on June 26, 2006, the author conducted field work on the site, inventorying existing wells and verifying current water levels. The principal well for the proposed ISL test site, OW9, was intact, however, other wells in the immediate vicinity had been plugged and abandoned. The current water level in OW9 was 127.6 feet below the ground surface. Past water level measurements from The Wyoming State Engineer’s Office (SEO) include 125 feet measured on August 16, 1979 and 125.9 feet measured on July 7, 1988. Thus, water levels have remained essentially unchanged since the well was originally installed on the property.

19


SECTION 17                     ADJACENT PROPERTIES

Mineralization is present on adjacent properties. The 1985 report by Malapai Resources proposed consolidation of properties within the vicinity (10 – 15 miles radius) into a large mining unit with the Peterson and Leuenberger projects as the central focus. In addition to the mineral properties described in this report, the following table lists the current EMC holdings within a 12 mile radius of the Peterson Uranium Project.

Total     5,580

EMC’s holding in T34N, R74W encompass portions of Malapai’s former Leuenberger project.

This report does not address these adjacent properties. Data available for the preparation of this report is historic data developed by previous owners of the property. EMC has not yet conducted its own exploration of the property.

The author has no material interest in the subject property or adjacent properties.

20


SECTION 18                     MINERAL PROCESSING AND METALLURGICAL TESTING

In 1984 Malapai Resources conducted physical testing on cores from the property and contracted Hazen Research Inc. to conduct leach studies for alkaline lixiviants. The results of this testing is contained in the historic report “1983-1984 Assessment Program, Peterson Project, Converse, county, Wyoming”, January, 1985.

The physical core testing was performed by WAMCO Lab of Casper, Wyoming. Testing was performed on 57 individual samples from 15 separate core holes. Porsity in the sand units ranged from 11.2 to 36 %. Permeability ranged from 220 to 10,850 millidarcies.

Testing by Hazen utilized both agitation leaches and column leach testing with alkaline lixiviant in various concentrations ranging from 2 to 4 gm/l NaHCO3. The report recommends a lixiviant concentration of 3 gm/l NaHCO3. The agitation leach produced the highest recovery with recoveries as high as 95%. Column leach studies ranged from 63 to 91 %. Two samples tested contained carbonaceous material and recoveries of 18 and 21% were reported.

These test results indicate that the uranium mineral resources at the Peterson Uranium Project are leachable under alkaline conditions as is being employed by other inistu operations in the vicinity such as PRI’s Highland operation. As this report is focused on mineral resources the reported results do not consider recovery in the reporting of mineral resources. As the Peterson Uranium Project moves towards development, a 43-101 mineral reserve report should be developed that, as a minimum, confirms previous metallurgical studies and investigations and confirms the results of previous hydrological investigations and studies including verification of pump test data and determination of current ground water levels and quality.

21


SECTION 19                     MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

No economic evaluation of the mineralization described herein was completed. Thus, the estimate that follows is solely a mineral resource estimate. Mineral resources are not mineral reserves and do not have demonstrated economic viability. Previous estimates assumed mining by insitu leach methods. The current estimate assumes ISL mining. Drill data demonstrates reasonable concentrations of mineralization and the location of mineralization is defined by drilling in three dimensions. The mineralization is shallow and limited portions may not be sufficiently below the water table to be feasible for ISL.

Although there is limited infrastructure at the site, the site is located only 10 miles northwest of Douglas, Wyoming. Portions of the property are crossed by Wyoming Highway 93. The proximity of the site to transportation will be beneficial with respect to transportation of equipment, supplies, personnel and products to and from the site. Malapai established two water wells as part of their hydrologic evaluation of the property. Electrical power and natural gas transmission lines are located within 10 miles of the site. Thus, the basic infrastructure necessary to support an ISL mining operation, power, water and transportation, is located within reasonable proximity of the site. Typically ISL mining operations will also require a disposal well for limited quantities of fluids that cannot be returned to the production aquifers. Commonly oil and gas wells within aquifers that have been or can be condemned for public use are utilized for such purposes. Although not investigated as part of this report, oil and gas wells, both abandoned and producing, are located in the immediate vicinity of the site and nearby ISL operations such as PRI’s Smith Ranch and Highland mines have disposal wells.

With regard to the socioeconomic and political environment, Wyoming mines have produced over 200 million pounds of uranium from both conventional and ISL mine and mill operations. The state has ranked as the number one US producer of uranium since 1994. Current Wyoming uranium production is from ISL mining operations in the Powder River Basin located just north of the Peterson Uranium Project. 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.

In order to conduct exploratory drilling of the property, EMC will be required to obtain permits (License to Explore) from the State of Wyoming Department of Environmental Quality and the BLM. Mine development will require a number of permits depending on the type and extent of development, the major permit being the actual mining permit issued by the State of Wyoming Department of Environmental Quality, Land Quality Division. Mineral processing for uranium will require a source materials license from the US Nuclear Regulatory Commission. Wyoming rules and regulations regarding ISL and conventional mining of uranium have been in place for more that twenty years and state regulators are experienced with the permitting of new operations, regulation of active operations, and the regulatory processes related to decommissioning of operations. There are no pre-existing mining and/or mineral processing facilities or related wastes on the property which may encumber the property.

Uranium mining in Wyoming is subject to property and mineral severance taxation. Mineral severance tax for uranium was most recently addressed by Wyoming under House Bill 15 (HB 15): “Severance Tax – Uranium”, 2003 General Session. In 1991 the Wyoming legislature enacted a severance tax break that exempted uranium production form all severance tax as long as the price of uranium remained below $17 per pound. HB 15 set the maximum severance tax on uranium production at 4% to be phased in at a rate of 1% for each increase in price of $2 per pound. At current uranium prices the 4% severance tax would apply. At the federal level profit from mining ventures is taxable at corporate income tax rates. However, for mineral properties depletion tax credits are available on a cost or percentage basis whichever is greater. For uranium the percentage depletion tax credit is 22% among the highest for mineral commodities, IRS Pub. 535.

The following mineral resource estimates were completed by Douglas Beahm, PE, PG, Principal Engineer, BRS Inc.

Assumptions
  1.

Radiometric equilibrium was assumed; see Section 20.

  2.

A unit weight of 125 pounds per cubic foot or 16 cubic feet per ton was assumed, based on the author’s experience working in operating mines in the Gas Hills within similar tertiary sandstone uranium mineralization where reserve estimates were routinely compared to actual production.

The mineralization is closely drilled, approximately fifty foot centers across the mineralized trends and one hundred to two hundred foot centers along the axis of the trends. The drilling demonstrates continuity particularly along the mineralized trends. Based on the drill density and the continuity of each mineralized horizon along the trends the mineral resource estimate meets the criteria as either measured or indicated mineral resources under the CIM Standards on Mineral Resources and Reserves. Mineral reserves are reported based on GT cutoffs of 0.1, 0.25 and 0.5. For reporting purposes the 0.25 cutoff is recommended and is thus highlighted in the mineral resource tabulations that follow.

As shown on Figure 10, seven distinct mineralized trends are defined by drilling. These trends are within the B, C and D sands of the Fort Union Formation and are separated vertically and spatially. Separate mineral resource estimates were completed for each separate trend and within each host sand unit. Within the distinct mineralized zones, individual intercepts were combined to represent the GT for the hole within that zone. The location of the mineralized zone was taken to be the top of the mineralization. The drill data was then summarized and contoured by GT ranges; the contained pounds of uranium were calculated by multiplying the measured areas by GT; total tonnage was

23


calculated by contouring thickness; tonnage by GT range was estimated based on the ratio of GT areas to total tonnage; and the results summed.

Summary of Estimated Mineral Resources

Economics, mining method, and recovery will dictate the appropriate cutoff grade and/or GT to be applied to the in-the-ground mineral resources. The 0.10 GT cutoff estimates were reported to assess the total mineral resource. The 0.25 cutoff is more appropriate for current insitu leach operations and is recommended for reporting purposes. Based on this recommendation the following measured and indicated mineral resources are estimated:

SECTION 20                     OTHER RELEVANT DATA AND INFORMATION

Radiometric Equilibrium

The great majority of the data available for estimation of mineral resources is radiometric geophysical logging data from which the uranium content is interpreted. Radiometric equilibrium conditions may affect the grade and spatial location of uranium mineralization. Generally an equilibrium ratio (Radiometric eU3O8 to Chemical U3O8) is assumed to be 1, i.e. equilibrium is assumed. For the Peterson Uranium Project data is available for the evaluation of radiometric equilibrium. Available chemical data from 29 core holes is summarized in the following table.

Based solely on a comparison of total GT the sample assays demonstrate that the mineralization is generally in radiometric equilibrium. The equilibrium ratio varies by area with Section 36 showing the greatest apparent depletion and the adjacent Section 35 showing the greatest enrichment. Since numerical averages can be skewed by extremely high or extremely low values equilibrium data can also be evaluated statistically by methods such a linear regression. If a mineralization is in equilibrium the linear regression of chemical and radiometric values should yield a line with a slope of 1 and an intercept of 0. The following plot shows a linear regression comparison of the Peterson chemical and radiometric data. The Slope is 1.11 with and intercept of -0.11. This analysis would indicate a slight enrichment since the slope is greater than 1.


In summary, given the level of available data an assumption of radiometric equilibrium is reasonable with respect to mineral resources. It is recommended that in the future assessment of mineral reserves additional data relative to radiometric equilibrium be developed and equilibrium be evaluated for each mineralized zone rather than for the mineralization as a whole.

Water Levels

  1.

For ISL operations it is critical that the mineralization be below the water table. Existing hydrologic data was available from APS reports. To confirm this data on June 26, 2006, the author conducted field work on the site, inventorying existing wells and verifying current water levels. The principal well for the proposed ISL test site, OW9, was intact, however, other wells in the immediate vicinity had been plugged and abandoned. The current water level in OW9 was 127.6 feet below the ground surface. Past water level measurements from The Wyoming State Engineer’s Office (SEO) include 125 feet measured on August 16, 1979 and

28


125.9 feet measured on July 7, 1988. Thus, water levels have remained essentially unchanged since the well was originally installed on the property. As stated in the recommendations it is recommended that previous hydrological investigation and studies including verification of pump test data and determination of current ground water levels and quality be confirmed.

29


SECTION 21                     INTERPRETATION AND CONCLUSIONS

This report summarizes the mineral resources within the property known as the Peterson Uranium Project and held via unpatented mining lode claims and State leases by Energy Metals Corporation. It was the objective of this report to complete the estimate of mineral resources, and that objective was met. The available data does define a mineralized trend specifically in the PAR and GL Claims in the upper sands of the Fort Union Formation. These mineralized trends are well defined by drilling and the mineral resource estimate meets the CIM definitions for either measured or indicated mineral resource depending on the continuity of each specific mineralized horizon. There is insufficient data available at this time to evaluate the L Claims.

30


SECTION 22                     RECOMMENDATIONS

The following recommendations are appropriate as the property moves toward development.

  2.

Confirm previous metallurgical studies and investigations including the collection of additional core samples for testing.

  3.

Confirm previous hydrological investigation and studies including verification of pump test data and determination of current ground water levels and quality.

  4.

Complete a mineral reserve and economic feasibility study including preparation of a 43-101 compliant mineral reserve report.

  5.

For future assessments of mineral reserves additional data relative to radiometric equilibrium should be developed and equilibrium be evaluated for each mineralized zone rather than for the mineralization as a whole.

  6.

Historic data from the L claims should be obtained if possible. In the event such data is not available the area should be evaluated by drilling.

  7.

Determine the potential for developing the property as a satellite operation feeding existing facilities in the area and/or consolidating this property with other properties in the vicinity to support the capital investment of a new central processing facility.
