Data Verification
The primary assay data for the West Slope Project is downhole geophysical log data, all of which is historical in nature; as of the effective date of the 2022 Technical Report, Anfield had yet to drill on the West Slope Project. See “The West Slope Project – Subsequent Works” for drilling conducted by Anfield at the West Slope Project following the effective date of the 2022 Technical Report. The author of the 2022 Technical Report has examined the geophysical logs in possession of the Company for the US DOE lease tracts, explored during the 1950s by the USGS on behalf of the US AEC, and later from the 1970s to early 2000s by Cotter. The Company also owns an extensive library of geophysical, geological, and mine permitting and development documents and data that served as a basis for evaluating the West Slope Project.
The historical data meets the standards employed by the uranium exploration and mining industry in the United States at the time it was collected. Cotter was a significant explorer and developer of uranium deposits in the western United States. The data collected was generated professionally and is considered adequate for the calculation of new mineral resources.
BRS personnel generated a digital database from the original files of Cotter. The file included: Drill hole ID, northing and easting coordinates (NAD-27, Colorado South state plane), collar elevation, depth drilled, drift direction and distance (if recorded), total depth drilled, and depth, thickness, and grade %eU 3 O 8. When posted, vanadium grade % was also entered in the excel file. However, vanadium grade % is very limited in scope in the Cotter database. For the estimates of contained vanadium in the mineral resources, the average ratio of the mined material (vanadium to uranium) from past mineral production at each lease tract, was utilized. Typically, this is a 5:1 to 7:1 ratio, vanadium to uranium, in the Uravan district. For those posted intercepts in the historical database, with both uranium and vanadium grade %s, a comparison of their ratios was overall similar to those reported from past production.
Radiometric equivalent data for the depth, thickness and grade of uranium was available in the original files from the Cotter for each drill hole used in the mineral resource calculation.
The US AEC published information on the calibration standards for geophysical logging and on gamma log interpretation methods. The standard manual log interpretation method was the half-amplitude method. The US AEC and its successor agency the Energy Research and Development Administration conducted workshops on gamma-ray logging techniques and interpretation as did private companies including Century Geophysical. The principal author, Douglas L. Beahm attended the geophysical log interpretation workshop conducted by Century Geophysical. On November 19, 1976, the author received certification in geophysical log interpretation from Century Geophysical after attending their short course.
For verification purposes, 33 drill holes containing 51 mineralized intercepts were selected representing the range of mineralization observed from each of the four JD leases in rough portion to the numbers of drill holes within each lease. The author re-calculated the mineralized intercepts for each drill holes to verify the original log interpretation. Mineralization in the verification drill holes ranged from a high GT (as defined below) value of 9.10 to a low value of 0.14. Barren holes were examined but not included in the analysis.
