  1. Deep Yellow currently owns 100% of Tumas. Oponona has an option to acquire 5% of the Project however the option is yet to be exercised;
  2. Totals may not match area tonnes due to rounding.

Notes:

For the Namibian Resources / Reserves

  • XRF chemical analysis unless annotated otherwise. eU3O8 – equivalent uranium grade as determined by downhole gamma logging.
  • 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.
  • All metrics presented on a 100% ownership basis (apart from the "Attributable Resources" column)

For the Australian Resources Reserves

  • Tonnes = metric dry tonnes; Appropriate rounding has been applied, and rounding errors may occur.
  • Using cut combined U3O8 composites (combined chemical and radiometric grades).
  • Metallurgical plant recovery factors are not applied to total metal content.
  • Using chemical U3O8 composites from drill core.
