Gold mine which includes four pits designated the Mulatos pit, Victor pit, La Yaqui pit and the Cerro Pelon pit. Production started in 2006.
Owned by Alamos Gold Inc.

Disseminated, epithermal and high-sulphidation gold system hosted within an Oligocene aged rhyodacite flow dome and breccia sequence. The deposit is related to a vast hydrothermal alteration zone that extends over 10km². Gold mineralisation is found predominantly within large pervasive zones of silica and advanced argillic alteration. Zones of quartz veins and quartz stockwork are rare. The sulfide zone constitutes the deepest part of the deposit and underlies a layer of mixed zone.

Note on the mineral list: Unspecified gold/silver telluride minerals are also mentioned.

Located approximately 220 kilometres by air east of the City of Hermosillo.
