Notes
Figures have been rounded and totals may reflect small rounding errors.
XRF chemical analysis unless annotated otherwise.
♦ eU3O8 – equivalent uranium grade as determined by downhole gamma logging.
# Combined XRF Fusion Chemical Assays and eU3O8 values.
Where eU3O8 values are reported it relates to values attained from radiometrically logging boreholes.
Gamma probes were calibrated at Pelindaba, South Africa in 2007. Recent calibrations were carried out at the Langer Heinrich Mine calibration facility in July 2018 and September 2019.
During drilling, probes are checked daily against standard source.
