Por: Antonio Ramos, Nexa Resources, y Nils Sarmiento y Peter Cerna, independientes.AbstractThe ~ 106 Ma Cerro Lindo volcanogenic massive sulfide deposit (VMS) consists of four trends of subparallel sulfides, elongated from NW-SE with weak inflection in the southern portion, composed by semi-massive to massive pyrite and barite, with Zn-Cu-Pb-Ag mineralization and specific zones with precious metal su|perimposed by late events due to reactivation of the hydrothermal system. In this stage of mineralogical evolution, it marks a stage where cp II-ef II is replaced and encompassed by cp III, mainly in the Pahuaypite, Milpo and Casuarinas-OB trends, mainly affecting the ore bodies (OB), OB1, OB5, OB6, OB7, this zoning occurs both vertically and horizontally, reflecting the thermal and chemical gradient during the formation of the reservoir. This condition causes difficulties in metallurgy, since zn is encapsulated in Cu concentrates, the importance of sectorizing these zones to optimize production and improve the quality of the concentrate.
