Huaron
Huaron is an underground polymetallic silver mining distrcit located in the department of Pasco, in the Peruvian central Andes. The mine was acquired by Pan American in 2001. Silver, zinc, lead, and copper mineralization is present as epithermal veins, mantos, and limestone replacements. The mining method is a combination of conventional cut and fill, mechanized cut and fill, and mechanized sub-level long hole-stopping. Ore is treated by crushing, ball mill grinding, selective flotation of the ore to concentrates, followed by thickening and filtering to produce silver in copper, lead, and zinc concentrates. Huaron represents one of the largest silver reserves in Peru and in the world having estimated reserves of 61.3 million oz. of silver.
