Sierra Target

The Sierra Target is located in the central portion of the El Cobre Property west of the town of Batacosa. Two historic (1950s) workings have been located on top of Miocene volcanic units giving over 700 meters of relief above the Montoso porphyry systems exposures located to the east.

The Sierra program has commenced including mapping, trenching and channel-panel sampling of the young volcanic hydrothermal breccia diatreme structure (see News Release WMR 13-05 and WMR 14-11).
