Capricorn Copper consists of several structurally controlled, sediment-hosted copper deposits located within the Western Fold Belt of the Mt Isa Inlier. There are two dominant styles of mineralisation at Capricorn Copper: - breccia-hosted within quartzites – Mammoth and Greenstone deposits; and - shear-hosted within shales/siltstones – Esperanza, Esperanza South and Pluto deposits. Esperanza South Esperanza South is a steeply plunging breccia located between the NNE-SSW-striking hangingwall and footwall margins of the Esperanza Fault zone. The footwall is defined by the easternmost shear within the Esperanza Formation. The fault zone envelope is approximately 50 – 70m wide. Mineralisation dips sub-parallel to the hangingwall at around -75° to the west, with a SSW plunge which steepens at depth from around -50° to -75°. The hypogene mineralisation at depth consists of chalcopyrite and pyrite exhibited as fracture fill, breccia matrix and massive forms. Supergene enrichment processes play a significant part of localising mineralisation at ESS, particularly in the upper 500m of the orebody. This weathering profile is represented by a broad weathering cap to the base of oxidation under which structural pathways have promoted downward percolation of meteoric fluids. These pathways have created supergene enrichment pathways which broadly run sub-parallel to the main structural envelope and in the most well developed zones consist of a barren, massive earthy haematite core (the ........

Of the five known deposits at Capricorn Copper with three in production: - Esperanza South (ESS), Mammoth and Greenstone. The other two deposits – Esperanza and Pluto – are planned to come into production from 2026. Access to ESS and Mammoth is via two separate declines. Access to Greenstone is via an access drive from the Mammoth decline. At Mammoth, the historical decline has been rehabilitated and extended to provide access to mining areas known as Mammoth Remnants and Mammoth Deeps, and a further access drive from the Mammoth decline is planned to access Esperanza and Pluto for mining in the future. At ESS, Capricorn Copper has developed new mine infrastructure comprising the decline, ventilation rises, power supply network and groundwater pumping. At Greenstone, a separate return air rise and emergency egress rise have been developed. Mining in ESS applies sub-level caving. Mining at Mammoth and Greenstone applies long-hole open stoping with waste-rock or paste fill. In the future, mining of Esperanza and Pluto will employ LHOS mining methods. Ore is transported by truck to surface via the ESS and Mammoth declines (as applicable). At Greenstone and Mammoth waste rock is partially used as backfill with surplus waste rock trucked to surface and deposited in the waste rock dump. The Capricorn Copper operations team is responsible for operational management of the mine, including short-to-long term planning, mine design and scheduling, ventilation, drill and blast ........
