Sampling

The database used in the 2022 Technical Report is historical in nature. As of the effective date of the 2022 Technical Report, Anfield had not performed any exploratory activities at the West Slope Project. The primary assay data for the West Slope Project is downhole geophysical logging. Historically, the mineralized uranium intercepts from the gamma-logs were calculated by Cotter’s in-house geophysical logging and geology department, creating a printout of the gamma-ray logs, and outlining the mineral intercepts at various cutoffs. Each downhole log typically consisted of gamma-ray, resistivity, and spontaneous potential curves plotted by depth. BRS created a digital database from this information including the hole location, elevation, downhole drift, and mineralized intercepts. The digital data was checked and compared to available drill hole maps.

Interpretation of radiometric equivalent uranium grades was verified by re-interpretation of a representee portion of the original geophysical logs, as discussed in Section 12 of the 2022 Technical Report.

The resistivity and spontaneous potential curves are mainly used to identify and correlate the sandstones and mudstones. The gamma-ray curves are used to measure the equivalent amounts of uranium oxide (eU 3 O 8) present in the rock. The logging equipment was regularly calibrated at test pits operated by the DOE at Grand Junction, Colorado in accordance with industry standards at the time.

Additional data includes limited vanadium chemical assays of cored intervals or drill cuttings. The vanadium assay data complimented the historical mineral production records to determine the ratio of vanadium to uranium. Production records show a vanadium : uranium ratio of 5.8:1 for the West Slope Project. The mineral resource estimates use a lower vanadium : uranium ration of 5:1 as a conservative measure as described in Section 14 of the 2022 Technical Report.
