Announcement summary: | depletion for that production year. This update includes drillhole data acquired between July 2020 and June 2022, and also uses mapping and sampling information collected from underground development to inform the interpretation. The 2022 model uses an approach to interpretation consistent with that used for previous models. The Reasonable Prospects test uses updated commodity prices and exchange rate. Copper and gold recoveries have been updated based on plant performance. The model has been created and classified assuming it will underpin an assessment of the applicability of the Block Caving (BC) mining method but is also valid for evaluating a Sub-level Caving (SLC) mining method. Mineral Resources The estimated Mineral Resources for the Carrapateena deposit are shown in Table 3. The Mineral Resources estimate has been reported in accordance with the 2012 edition of the JORC Code. For mineralisation above the 3,600 RL, a nominal cut-off of A$25 Net Smelter Return (NSR) per tonne2 has been used to generate a continuous shape3 in which all material was deemed to have reasonable prospects of eventual economic extraction, assuming a BC operation. |
