The intermediate-sulfidation epithermal vein crops out along 1.5 km, with N70ºW strike and has a subvertical dip. The mine went into production in September 2007 and ranks sixth worldwide in silver production. It is the second largest silver mine in Peru and produced 263 t of Ag in 2011 (8.77 Moz).
