Volcan Compañía Minera S.A.A. and its subsidiary companies engaged in the mining sector operate the mining unit of Yauli, which includes the Carahuacra Norte open pit mine.
In Q4 2022, Glencore commenced a process to dispose of its 23.3% economic interest in Volcan, which is ongoing. As a result, the carrying amounts of Volcan assets and liabilities as at 31 December 2023 and 31 December 2022 are classified as held for sale.
The Carahuacra deposit lies on the southwest flank of the Yauli anticline, formed by Tertiary folding. Manto ore, formed before the climax of the Andean orogeny, consists mainly of ferroan sphalerite and pyrite, with negligible chalcopyrite. These were later brecciated tectonically to form two zones of 'breccia ore'. The last phase of mineralization involved formation of epithermal cross veins with sphalerite, pyrite, galena, tetrahedrite, and jamesonite, and irregular cementation of fragments in the breccia ore by sphalerite-galena and pyrite-marcasite. Supergene alteration, particularly pronounced in the breccia zone, has formed ore much enriched in silver (native silver, argentite, pyrargyrite).
