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 and sensitivity checks are conducted by periodic re-logging of attest hole to confirm operation between 2008 and 2013.
During drilling, probes are checked daily against standard source.
