OZ Minerals Limited announced the Carrapateena November 2020 Mineral Resources statement relates to an updated Mineral Resources estimate for the Carrapateena copper-gold deposit, which is an iron oxide copper-gold (IOCG) deposit located in central South Australia on the eastern margin of the Gawler Craton. This Mineral Resources statement is an update to the November 2019 Mineral Resources statement as at 30 June 2020. This update includes drillhole data acquired between June 2019 and June 2020, and also uses mapping information collected from underground development to inform the interpretation. The 2020 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 recent test work. 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. The estimated Mineral Resources for the Carrapateena deposit. 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 NSR per tonne2 has been used to generate a continuous shape 3 in which all material was deemed to have reasonable prospects of eventual economic extraction, assuming a BC operation. The Carrapateena Breccia Complex is located within the Olympic copper gold (Cu-Au) Province on the eastern edge of the Gawler Craton. It is hosted within Donington Suite granite and is unconformably overlain by approximately 480 m of Neoproterozoic sediments. Mineralisation and alteration are in the form of that seen at other large South Australian IOCG deposits, including Prominent Hill and Olympic Dam. For modelling and estimation, the deposit geology was interpreted into several domains based on a combination of lithology, chemistry and mineralisation style, including a chalcopyrite-dominant domain, bornite-dominant domain, pyrite-chalcopyrite domain, gold enriched zones, leached zones, mineralised granite domain and barren hematite breccias. All basement samples consist of diamond drill core (NQ, NQ2, HQ and PQ) cut with a manual or automatic core saw. The drill core is sampled as half core, except for PQ core, metallurgical holes and field duplicates, where quarter core was sampled. All available basement drill core, except for metallurgical and some geotechnical holes and some instances where holes passed through large intervals of granite outside the mineralisation, were sampled on 1 m intervals but respect geological contacts in places. Entire samples were crushed then pulverised. For OZ Minerals drill holes, sample preparation included drying, crushing and pulverising in full to a nominal 90% passing 75 microns. For Teck Cominco Australia Pty Ltd. (Teck) drill holes, samples were pulverised to a nominal 85% passing 75 microns. For Teck drill holes, a combination of RC and mud-rotary was used for precollars. HQ diamond drilling was used through to top of basement and NQ through basement to EOH. For OZ Minerals drill holes, diamond drilling was used from surface with a combination of PQ, HQ and NQ2 core sizes. OZ Minerals underground drilling commenced in 2019 with a combination of HQ and NQ core sizes. Samples were sent to either the Bureau Veritas (Amdel) Adelaide laboratory by (OZ Minerals and large proportion of Teck drill holes) or the Intertek Genalysis Perth laboratory (limited Teck holes). Copper and silver were analysed using a multi-acid digest and ICP-OES (copper and silver) or ICP-MS (silver, OZ Minerals holes). Gold grades were analysed using fire assay (typically 20 grams or 40 grams) and, in nearly all cases, an AAS finish.
