Summary:

Historically, the Cerro de Pasco deposit had a supergene oxide cap. The only remaining area of the deposit with oxide mineralization is in the Santa Rosa open pit area. In the Santa Rosa area in the southern part of the open pit, there is a remnant of the Mitu Group (oxidized siltstones and conglomerate) cut by phreatic and hydrothermal breccias. More recent mapping and sampling during mining identified the host rock as Mitu Group interbedded sandstone and conglomerate, cut by C2 veins resulting in massive and disseminated mineralization. Supergene oxidation generated the mined zone of silver-gold oxide mineralization which is 800 m long (and open to southeast), 400 m wide, and 125 m deep. In 2022, the integral geological model of In Situ Oxides was updated, characterizing three domains of gold and silver mineralization, called: (i) volcanic protolith hydrothermal breccia (BxH-v), sedimentary protolith hydrothermal breccia (BxH-s) and pyrite IV (at the base of the In Situ Oxide deposit with high silver values).
