Project Details


The Los Calatos project is located in southern Peru, near and in a similar geological setting to three large operating copper-molybdenum mines, Cuajone, Toquepala and Cerro Verde. The project, which covers an area of 275km2, has been designated a project of national interest by the Peruvian government, which enables Hampton Perú (a 100% held subsidiary of Metminco) to acquire surface title for infrastructure by direct purchase from the state. In addition, there is no competing land usage, seawater is planned to be used for metallurgical processing purposes and power costs are low by comparison to similar operations in Chile. A total mineral resource (measured, indicated and inferred mineral resource categories) of 1.42Bt at 0.47% copper and 0.022% molybdenum has been estimated. According to a mining scoping study, the preferred mining scenario comprises a combination of an open pit with a life of seven years and an underground block cave operation with a 24-year life at a mining and processing rate of 21.9Mt/y (60,000t/d).
