  1. Joint Ore Reserves Committee (JORC) and CIM Definition Standards were followed for Mineral Reserves.
  2. Mineral Reserves were generated using the January 1, 2021 mining surface.
  3. Mineral Reserves are reported at a 0.10% Cu cut-off grade.
  4. Mineral Reserves are reported using long-term copper, gold, and silver prices of $2.75/lb, $1,500/oz, and $18.50/oz, respectively.
  5. An average CMM copper process recovery at block model domain recovery, gold process recovery of 65%, and silver process recovery of 70% is based on geo-metallurgical domains and actual plant values.
  6. An average Ingerbelle copper process recovery of 88.5%, gold process recovery of 71%, and silver process recovery of 65% is based on geo-metallurgical domains, historical recoveries, and recent testwork.
  7. Average bulk density is 2.78 t/m3.
  8. Stockpile grades are approximations based on grade control results.
