Reserve and Resource Estimates
Karatau Uranium Mine
Scott Wilson Roscoe Postle Associates Inc. ("SWRPA") has provided the Company with an updated NI 43-101 compliant mineral reserve and resource estimate as at December 31, 2009 for the Karatau Uranium Mine. The updated Karatau resource estimate incorporates new drilling information from 45,277 metres of drilling from an additional 67 holes that were not included in the previous SWRPA resource estimate as at November 2007.
Compared to the previous resource estimate, the new estimate shows a significant increase in the Indicated and Inferred Resource categories as follows:
- 12% increase in Indicated Resources to 32.6 million pounds U(3)O(8)
(100% basis)
- 373% increase in Inferred Resources to 9.5 million pounds U(3)O(8)
(100% basis)
SWRPA has also converted a portion of the Indicated Resources to a Probable Reserve by assuming a 90% well field recovery rate. The Probable Reserve estimate for Karatau is 12.5 million tonnes at a grade of 0.106% U(3)O(8), containing 29.3 million pounds U(3)O(8) (100% basis).
In SWRPA's opinion, in addition to the Indicated and Inferred Mineral Resources, there is significant potential to increase the mineral resource base. Exploration drilling indicated potential in the range of 20 million to 28 million tonnes grading 0.071% U(3)O(8) to 0.118% U(3)O(8), containing 41.6 to 57.2 million pounds U(3)O(8). This potential quantity is based on the Volkovgeologia P1 mineral resource estimate. The tonnage and grade for the potential quantity is conceptual in nature and further exploration is required to determine if this mineralization can be classified as Mineral Resources. It is uncertain if further exploration will result in the target being delineated as a Mineral Resource.
Additional details of the updated reserve and resource estimate for Karatau can be found in Appendix "A" attached hereto.
South Inkai Uranium Mine
Hellmann & Schofield Pty Ltd. has provided the Company with an updated NI 43-101 compliant mineral reserve and resource estimate for South Inkai as at December 31, 2009. This estimate was completed in order to conduct an independent assessment of mining reserves at South Inkai to demonstrate the appropriate equivalence under NI 43-101.
In the updated resource estimate, a small amount of indicated resource was upgraded to the measured category. In addition, Hellman & Schofield have estimated reserves for South Inkai as follows:
- Attributable proven reserves of 0.9 million pounds U(3)O(8)
- Attributable probable reserves of 22.7 million pounds U(3)O(8)
Additional details of the new reserve and resource estimate for South Inkai can be found in Appendix "B" attached hereto.
Completion of Acquisition of Wyoming Assets
The acquisition of 100% of the MALCO Joint Venture ("MALCO") from wholly-owned subsidiaries of AREVA and EDF for US$ 35 million in cash was completed on January 25, 2010.
The assets of MALCO include the licensed and permitted Irigaray ISR central processing plant, the Christensen Ranch satellite ISR facility and associated U(3)O(8) resources located in the Powder River Basin of Wyoming. Uranium One expects that initial production from the Christensen Ranch project will commence in 2011.
The Irigaray central processing plant currently has the capacity to produce approximately 1.3 million pounds of dried U(3)O(8) per year. Uranium One intends to expand the processing capacity at Irigaray in line with the facility's Nuclear Regulatory Commission license to approximately 2.5 million pounds U(3)O(8) per year by incorporating a vacuum dryer purchased for use at the Company's Moore Ranch project.
Uranium One anticipates that its Moore Ranch project will now become a satellite ISR operation, with loaded resins being transported to Irigaray for further processing into dried U(3)O(8). The Company's other projects in the Powder River Basin, including Ludeman, Peterson, Allemand-Ross and Barge could also be developed as satellite operations, with final processing through Irigaray.
Update to ARMZ Standstill
Uranium One also announced that, at the request of JSC Atomredmetzoloto ("ARMZ"), the Company has agreed that ARMZ may temporarily exceed the 19.95% standstill under the Framework Agreement between the two companies. This will enable ARMZ to settle certain option agreements that were entered into with the expectation that the transaction with the JUMI consortium, as originally structured, would have closed by now.
If Kazakh regulatory approval to the issuance of the 117,000,000 common shares underlying the debentures issued in January 2010 to the JUMI consortium is received before settlement of the option agreements, the debentures will automatically convert and ARMZ's holdings would not exceed the 19.95% cap; if option exercise occurs first, subject to applicable regulatory approvals (which have been received, including FIRB approval in Australia), ARMZ would own approximately 23.2% of Uranium One's outstanding common shares. If the convertible debentures remain outstanding in 12 months time, ARMZ has agreed to reduce its holdings to the 19.95% level at that time.

Appendix A
Karatau Uranium Mine Reserve and Resource Estimate
Scott Wilson Roscoe Postle Associates Inc. ("SWRPA") has provided Uranium One with an updated NI 43-101 compliant reserve and resource estimate as at December 31, 2009.
The estimate shows 12.5 million tonnes grading 0.118% U(3)O(8), containing 32.6 million pounds U(3)O(8) in indicated resources (16.3 million pounds attributable to Uranium One), 5.4 million tonnes grading 0.080% U(3)O(8), containing 9.5 million pounds U(3)O(8) in inferred resources (4.7 million pounds attributable to Uranium One), and 12.5 million tonnes grading 0.106% U(3)O(8), containing 29.3 million pounds U(3)O(8) in probable reserves (14.6 million pounds attributable to Uranium One).
The previously reported mineral resource estimate as at November, 2007 was 9.7 million tonnes grading 0.135% U(3)O(8), containing 29.3 million pounds U(3)O(8) in the indicated category (14.6 million pounds attributable to Uranium One), and 0.9 million tonnes grading 0.104% U(3)O(8), containing 2.0 million pounds U(3)O(8) in the inferred category (1.0 million pounds attributable to Uranium One).
Mineral resources for the deposit were estimated by Volkovgeologia using the system developed for Mongolia and the former Commonwealth of Independent States countries. SWRPA previously reviewed the parameters and methodology for the C1 and C2 mineral resources in 2007. Since that time no further drilling has been undertaken within the C1 mineral resource blocks. The outer limits of the C1 blocks have been slightly adjusted due to drilling on adjacent blocks. The minimum grade-thickness used in the current mineral resource estimate has been reduced to 0.04 m% from 0.06 m% used in the previous estimate. These amendments have resulted in a 3% reduction in contained U in the C1 blocks. The C2 mineral resources have increased since the 2007 estimate. Subsequent to the November 2007 mineral resource estimate, an additional 67 holes for a total of 45,277 m were drilled and incorporated into the database. SWRPA visited the property and reviewed the drill database, parameters, and methodology for the current C2 mineral estimate.
The Volkovgeologia mineral resource estimate reviewed for this report was as at November 2008. Subsequently, Karatau has produced 1,815 t U from the C1 mineral resource blocks. SWRPA has reduced the mineral resources by that amount to estimate mineral resources and reserves as at December 31, 2009.
SWRPA is of the opinion that the methodology used to estimate the mineral resources is appropriate and is in accordance with industry standards. SWRPA has reviewed the drill density, geological knowledge, and reconciliation of producing wellfields and has reclassified the resources to conform to the definitions as stated by the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves (December 2005). Based on the data density, demonstrated continuity of the mineralization, and established high recoverability of uranium from the mineralization, 100% of the C1 category and 50% of the C2 category mineral resources can be converted to the indicated resource classification. The remaining 50% of the C2 category mineral resources can be converted to inferred resources. A summary of the mineral resource estimate is presented in Table 1.

6. Figures subject to rounding.
The resource estimate is based on parameters (e.g. cut-off grade, grade-thickness, internal waste, mineralization to waste ratio, block size, permeability and density) used for the South Inkai deposit and originally approved by the Ministry of Geology and the Ministry of Atomic Energy and Industry of the USSR. The modelling methodology applied considered similar structural and tectonic characteristics, lithological and facies types and hydrogeological and geotechnical features. The 2008 resource estimate is based on information from approximately 104,000 metres of drilling. The indicated resources have been drilled on fences 200 metres apart, with holes spaced at 50 metres. The inferred resources have been drilled on fences 400 metres apart, with holes spaced at 50 to 200 metres apart. Gamma ray logging is used in conjunction with the geological interpretations to determine the uranium content.
In addition to the mineral resource estimate, SWRPA also converted part of the indicated resources to probable reserves by assuming a 90% wellfield recovery. A summary of mineral reserves is presented in Table 2.

The successful extraction of the deposit by means of the in situ leach technique is mainly due to the favorable characteristics for uranium extraction where the uranium is hosted in zones of acceptable permeability with good solution mining conditions, a low carbonate content of the mineralized host rocks, and exhibits a uniform distribution of uranium mineralization.
The updated mineral resource and reserve estimate for the Karatau Uranium Mine is contained in an independent technical report prepared by SWRPA for filing in accordance with the requirements of NI 43-101.
Appendix B
South Inkai Uranium Mine Reserve and Resource Estimate
Uranium One has received an updated resource and reserve estimate, as of December 31, 2009, from Hellman & Schofield Pty. Ltd. ("H&S") for the South Inkai Uranium Mine.
The estimate shows 6.1 million tonnes grading 0.011% U(3)O(8), containing 1.4 million pounds U(3)O(8) in the measured resource category (0.9 million pounds attributable to Uranium One), 33.2 million tonnes grading 0.045% U(3)O(8), containing 32.5 million pounds U(3)08 in the indicated resource category (22.7 million pounds attributable to Uranium One), 42.8 million tonnes grading 0.047% U(3)O(8), containing 44.4 million pounds U(3)O(8) in the inferred resource category (31.1 million pounds attributable to Uranium One), 6.1 million tonnes grading 0.011% U(3)O(8), containing 1.4 million pounds U(3)O(8) in the proven reserve category (0.9 million pounds attributable to Uranium One), and 33.2 million tonnes grading 0.045% U(3)O(8), containing 32.5 million pounds U(3)O(8) in the probable reserve category (22.7 million pounds attributable to Uranium One).
The previously reported mineral resource estimate dated December 31, 2008 was 34.0 million tonnes grading 0.053% U(3)O(8), containing 39.6 million pounds U(3)O(8) in the indicated category (27.7 million pounds attributable to Uranium One), and 42.8 million tonnes grading 0.047% U(3)O(8), containing 44.4 million pounds U(3)O(8) in the inferred category (31.1 million pounds attributable to Uranium One).
The independent estimation of the resources and reserves reported in Table 1 below used the ordinary block kriging method and is based on production and exploration information for the South Inkai Site 4, comprising mining blocks 1 to 7. The mining blocks correspond with prior reserve blocks 4-6-C1 and 4-8-C1, as submitted to the Yuzhkaznedra Territorial Department and Ministry of Energy and Mineral Resources of the Republic of Kazakhstan, the State Committee of Minerals Resources ("SCMR") in September, 2008. There are 438 holes drilled for C1 reserves in the area of interest, and the drill fences for C1 reserves are 200 m apart, with holes spaced at 50 m. Based on this information, H&S is of the opinion that all reserves estimated at the C1 Reserve confidence category under Russian estimation protocols at South Inkai, can be considered equivalent to the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (December 2005) Indicated Resources on the basis of similar contained estimated uranium. H&S is also of the opinion, after having analyzed the production and extraction efficiencies, that the C1 Reserves can be reported as Probable Reserves under the CIM code in terms of contained uranium. The compensating differences between grade and tonnage estimates are due to the different estimation techniques used and not to any intrinsic uncertainty in the contained uranium at South Inkai.
Primary down-hole radiometric data provided by Betpak Dala and Uranium One enabled H&S to confirm the probe data against core sample assays, and have assumed a disequilibrium factor of average 1.00 to do an estimation of the resources using ordinary block kriging ("OK"). The OK technique used by H&S differs in general from the polygonal grade-thickness ("GT") methods traditionally applied in the past in that it gives estimates that are lower in grade and higher in tonnages, and contain more metal than a GT estimate done in the same rock volume.
Summary parameter information used to estimate the resources:
- radiometric data composited to 0.5 m
- radium from probe measurement adjusted to U% by applying
disequilibrium factor of 1.00
- rotation of the grid by 42 degrees anticlockwise
- estimation into blocks of 60 m W, 20 m N and 1 m depth (rotated grid)
- data search radii of 50 m W, 50 m N and 1 m depth for notionally
Measured Resources
- data search radii of 65 m W, 65 m N and 1.3 m depth for notionally
Indicated Resources
- a minimum of 16 data points and maximum of 32 x 0.5 m radiometric
composites within search radius for notionally Indicated and Measured
resources
- previously estimated Inferred Resources were not reviewed
- the same block dimensions and search criteria were used to estimate
the permeable proportions of blocks
Resources have been reported above a uranium cut-off grade of 0.01%.

Reserve and Resource Estimates
Karatau Uranium Mine
Scott Wilson Roscoe Postle Associates Inc. ("SWRPA") has provided the Company with an updated NI 43-101 compliant mineral reserve and resource estimate as at December 31, 2009 for the Karatau Uranium Mine. The updated Karatau resource estimate incorporates new drilling information from 45,277 metres of drilling from an additional 67 holes that were not included in the previous SWRPA resource estimate as at November 2007.
Compared to the previous resource estimate, the new estimate shows a significant increase in the Indicated and Inferred Resource categories as follows:
- 12% increase in Indicated Resources to 32.6 million pounds U(3)O(8)
(100% basis)
- 373% increase in Inferred Resources to 9.5 million pounds U(3)O(8)
(100% basis)
SWRPA has also converted a portion of the Indicated Resources to a Probable Reserve by assuming a 90% well field recovery rate. The Probable Reserve estimate for Karatau is 12.5 million tonnes at a grade of 0.106% U(3)O(8), containing 29.3 million pounds U(3)O(8) (100% basis).
In SWRPA's opinion, in addition to the Indicated and Inferred Mineral Resources, there is significant potential to increase the mineral resource base. Exploration drilling indicated potential in the range of 20 million to 28 million tonnes grading 0.071% U(3)O(8) to 0.118% U(3)O(8), containing 41.6 to 57.2 million pounds U(3)O(8). This potential quantity is based on the Volkovgeologia P1 mineral resource estimate. The tonnage and grade for the potential quantity is conceptual in nature and further exploration is required to determine if this mineralization can be classified as Mineral Resources. It is uncertain if further exploration will result in the target being delineated as a Mineral Resource.
Additional details of the updated reserve and resource estimate for Karatau can be found in Appendix "A" attached hereto.
South Inkai Uranium Mine
Hellmann & Schofield Pty Ltd. has provided the Company with an updated NI 43-101 compliant mineral reserve and resource estimate for South Inkai as at December 31, 2009. This estimate was completed in order to conduct an independent assessment of mining reserves at South Inkai to demonstrate the appropriate equivalence under NI 43-101.
In the updated resource estimate, a small amount of indicated resource was upgraded to the measured category. In addition, Hellman & Schofield have estimated reserves for South Inkai as follows:
- Attributable proven reserves of 0.9 million pounds U(3)O(8)
- Attributable probable reserves of 22.7 million pounds U(3)O(8)
Additional details of the new reserve and resource estimate for South Inkai can be found in Appendix "B" attached hereto.
Completion of Acquisition of Wyoming Assets
The acquisition of 100% of the MALCO Joint Venture ("MALCO") from wholly-owned subsidiaries of AREVA and EDF for US$ 35 million in cash was completed on January 25, 2010.
The assets of MALCO include the licensed and permitted Irigaray ISR central processing plant, the Christensen Ranch satellite ISR facility and associated U(3)O(8) resources located in the Powder River Basin of Wyoming. Uranium One expects that initial production from the Christensen Ranch project will commence in 2011.
The Irigaray central processing plant currently has the capacity to produce approximately 1.3 million pounds of dried U(3)O(8) per year. Uranium One intends to expand the processing capacity at Irigaray in line with the facility's Nuclear Regulatory Commission license to approximately 2.5 million pounds U(3)O(8) per year by incorporating a vacuum dryer purchased for use at the Company's Moore Ranch project.
Uranium One anticipates that its Moore Ranch project will now become a satellite ISR operation, with loaded resins being transported to Irigaray for further processing into dried U(3)O(8). The Company's other projects in the Powder River Basin, including Ludeman, Peterson, Allemand-Ross and Barge could also be developed as satellite operations, with final processing through Irigaray.
Update to ARMZ Standstill
Uranium One also announced that, at the request of JSC Atomredmetzoloto ("ARMZ"), the Company has agreed that ARMZ may temporarily exceed the 19.95% standstill under the Framework Agreement between the two companies. This will enable ARMZ to settle certain option agreements that were entered into with the expectation that the transaction with the JUMI consortium, as originally structured, would have closed by now.
If Kazakh regulatory approval to the issuance of the 117,000,000 common shares underlying the debentures issued in January 2010 to the JUMI consortium is received before settlement of the option agreements, the debentures will automatically convert and ARMZ's holdings would not exceed the 19.95% cap; if option exercise occurs first, subject to applicable regulatory approvals (which have been received, including FIRB approval in Australia), ARMZ would own approximately 23.2% of Uranium One's outstanding common shares. If the convertible debentures remain outstanding in 12 months time, ARMZ has agreed to reduce its holdings to the 19.95% level at that time.

Appendix A
Karatau Uranium Mine Reserve and Resource Estimate
Scott Wilson Roscoe Postle Associates Inc. ("SWRPA") has provided Uranium One with an updated NI 43-101 compliant reserve and resource estimate as at December 31, 2009.
The estimate shows 12.5 million tonnes grading 0.118% U(3)O(8), containing 32.6 million pounds U(3)O(8) in indicated resources (16.3 million pounds attributable to Uranium One), 5.4 million tonnes grading 0.080% U(3)O(8), containing 9.5 million pounds U(3)O(8) in inferred resources (4.7 million pounds attributable to Uranium One), and 12.5 million tonnes grading 0.106% U(3)O(8), containing 29.3 million pounds U(3)O(8) in probable reserves (14.6 million pounds attributable to Uranium One).
The previously reported mineral resource estimate as at November, 2007 was 9.7 million tonnes grading 0.135% U(3)O(8), containing 29.3 million pounds U(3)O(8) in the indicated category (14.6 million pounds attributable to Uranium One), and 0.9 million tonnes grading 0.104% U(3)O(8), containing 2.0 million pounds U(3)O(8) in the inferred category (1.0 million pounds attributable to Uranium One).
Mineral resources for the deposit were estimated by Volkovgeologia using the system developed for Mongolia and the former Commonwealth of Independent States countries. SWRPA previously reviewed the parameters and methodology for the C1 and C2 mineral resources in 2007. Since that time no further drilling has been undertaken within the C1 mineral resource blocks. The outer limits of the C1 blocks have been slightly adjusted due to drilling on adjacent blocks. The minimum grade-thickness used in the current mineral resource estimate has been reduced to 0.04 m% from 0.06 m% used in the previous estimate. These amendments have resulted in a 3% reduction in contained U in the C1 blocks. The C2 mineral resources have increased since the 2007 estimate. Subsequent to the November 2007 mineral resource estimate, an additional 67 holes for a total of 45,277 m were drilled and incorporated into the database. SWRPA visited the property and reviewed the drill database, parameters, and methodology for the current C2 mineral estimate.
The Volkovgeologia mineral resource estimate reviewed for this report was as at November 2008. Subsequently, Karatau has produced 1,815 t U from the C1 mineral resource blocks. SWRPA has reduced the mineral resources by that amount to estimate mineral resources and reserves as at December 31, 2009.
SWRPA is of the opinion that the methodology used to estimate the mineral resources is appropriate and is in accordance with industry standards. SWRPA has reviewed the drill density, geological knowledge, and reconciliation of producing wellfields and has reclassified the resources to conform to the definitions as stated by the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves (December 2005). Based on the data density, demonstrated continuity of the mineralization, and established high recoverability of uranium from the mineralization, 100% of the C1 category and 50% of the C2 category mineral resources can be converted to the indicated resource classification. The remaining 50% of the C2 category mineral resources can be converted to inferred resources. A summary of the mineral resource estimate is presented in Table 1.

6. Figures subject to rounding.
The resource estimate is based on parameters (e.g. cut-off grade, grade-thickness, internal waste, mineralization to waste ratio, block size, permeability and density) used for the South Inkai deposit and originally approved by the Ministry of Geology and the Ministry of Atomic Energy and Industry of the USSR. The modelling methodology applied considered similar structural and tectonic characteristics, lithological and facies types and hydrogeological and geotechnical features. The 2008 resource estimate is based on information from approximately 104,000 metres of drilling. The indicated resources have been drilled on fences 200 metres apart, with holes spaced at 50 metres. The inferred resources have been drilled on fences 400 metres apart, with holes spaced at 50 to 200 metres apart. Gamma ray logging is used in conjunction with the geological interpretations to determine the uranium content.
In addition to the mineral resource estimate, SWRPA also converted part of the indicated resources to probable reserves by assuming a 90% wellfield recovery. A summary of mineral reserves is presented in Table 2.

The successful extraction of the deposit by means of the in situ leach technique is mainly due to the favorable characteristics for uranium extraction where the uranium is hosted in zones of acceptable permeability with good solution mining conditions, a low carbonate content of the mineralized host rocks, and exhibits a uniform distribution of uranium mineralization.
The updated mineral resource and reserve estimate for the Karatau Uranium Mine is contained in an independent technical report prepared by SWRPA for filing in accordance with the requirements of NI 43-101.
Appendix B
South Inkai Uranium Mine Reserve and Resource Estimate
Uranium One has received an updated resource and reserve estimate, as of December 31, 2009, from Hellman & Schofield Pty. Ltd. ("H&S") for the South Inkai Uranium Mine.
The estimate shows 6.1 million tonnes grading 0.011% U(3)O(8), containing 1.4 million pounds U(3)O(8) in the measured resource category (0.9 million pounds attributable to Uranium One), 33.2 million tonnes grading 0.045% U(3)O(8), containing 32.5 million pounds U(3)08 in the indicated resource category (22.7 million pounds attributable to Uranium One), 42.8 million tonnes grading 0.047% U(3)O(8), containing 44.4 million pounds U(3)O(8) in the inferred resource category (31.1 million pounds attributable to Uranium One), 6.1 million tonnes grading 0.011% U(3)O(8), containing 1.4 million pounds U(3)O(8) in the proven reserve category (0.9 million pounds attributable to Uranium One), and 33.2 million tonnes grading 0.045% U(3)O(8), containing 32.5 million pounds U(3)O(8) in the probable reserve category (22.7 million pounds attributable to Uranium One).
The previously reported mineral resource estimate dated December 31, 2008 was 34.0 million tonnes grading 0.053% U(3)O(8), containing 39.6 million pounds U(3)O(8) in the indicated category (27.7 million pounds attributable to Uranium One), and 42.8 million tonnes grading 0.047% U(3)O(8), containing 44.4 million pounds U(3)O(8) in the inferred category (31.1 million pounds attributable to Uranium One).
The independent estimation of the resources and reserves reported in Table 1 below used the ordinary block kriging method and is based on production and exploration information for the South Inkai Site 4, comprising mining blocks 1 to 7. The mining blocks correspond with prior reserve blocks 4-6-C1 and 4-8-C1, as submitted to the Yuzhkaznedra Territorial Department and Ministry of Energy and Mineral Resources of the Republic of Kazakhstan, the State Committee of Minerals Resources ("SCMR") in September, 2008. There are 438 holes drilled for C1 reserves in the area of interest, and the drill fences for C1 reserves are 200 m apart, with holes spaced at 50 m. Based on this information, H&S is of the opinion that all reserves estimated at the C1 Reserve confidence category under Russian estimation protocols at South Inkai, can be considered equivalent to the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (December 2005) Indicated Resources on the basis of similar contained estimated uranium. H&S is also of the opinion, after having analyzed the production and extraction efficiencies, that the C1 Reserves can be reported as Probable Reserves under the CIM code in terms of contained uranium. The compensating differences between grade and tonnage estimates are due to the different estimation techniques used and not to any intrinsic uncertainty in the contained uranium at South Inkai.
Primary down-hole radiometric data provided by Betpak Dala and Uranium One enabled H&S to confirm the probe data against core sample assays, and have assumed a disequilibrium factor of average 1.00 to do an estimation of the resources using ordinary block kriging ("OK"). The OK technique used by H&S differs in general from the polygonal grade-thickness ("GT") methods traditionally applied in the past in that it gives estimates that are lower in grade and higher in tonnages, and contain more metal than a GT estimate done in the same rock volume.
Summary parameter information used to estimate the resources:
- radiometric data composited to 0.5 m
- radium from probe measurement adjusted to U% by applying
disequilibrium factor of 1.00
- rotation of the grid by 42 degrees anticlockwise
- estimation into blocks of 60 m W, 20 m N and 1 m depth (rotated grid)
- data search radii of 50 m W, 50 m N and 1 m depth for notionally
Measured Resources
- data search radii of 65 m W, 65 m N and 1.3 m depth for notionally
Indicated Resources
- a minimum of 16 data points and maximum of 32 x 0.5 m radiometric
composites within search radius for notionally Indicated and Measured
resources
- previously estimated Inferred Resources were not reviewed
- the same block dimensions and search criteria were used to estimate
the permeable proportions of blocks
Resources have been reported above a uranium cut-off grade of 0.01%.
