Volcan Compañía Minera S.A.A. and its subsidiary companies engaged in the mining sector operate the mining unit of Yauli, which includes the Andaychagua underground 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 Yauli unit region shows mineralization related to polymetallic epithermal systems, replacement bodies and polymetallic vein systems, as well as porphyry mineralization and skarns, thus indicating the great potential of the area. The southern portion of the Yauli Dome is including the San Cristobal polymetallic deposit. The San Cristobal-Andaychagua mining district includes only mantos and veins. The mantos are hosted by the Pucara limestone along the contact with the underlying Mitu Group, and occur mainly along the western flank of the Domo de Yauli. The veins are steeply dipping and crosscut rocks of the Mitu and Excelsior Groups, and locally the Chumpe and San Cristobal intrusions. Andaychagua Vein is one of the producers in the San Cristobal district, is one of the most important veins on the southeast side of the Chumpe intrusive. The vein lies on the northeast side of the Chumpe Anticline. About three and a half kilometers southeast of the San Cristobal Vein system. The Andaychagma Vein strikes N 30° E and dips 85° northwest. The vein can be traced on the surface for about four kilometers, three of which are in Mitu volcanic rocks and one of which in Excelsior Phyllites. The structure continues on the surface across the axial zone to the southwest side of the Chumpe Anticline, but only as a fault structure without apparent mineralization. The Andaychagua Vein carries sphalerite, galena, and silver minerals.
