Three companies released drilling results from current mining properties in Mexico during the first week of the year. Bear Creek’s Mercedes project is part of a cluster of low sulfidation epithermal deposits that include Las Chispas, Ermitaño, Santa Elena, Santa Gertrudis, Picacho and Cecilia, among others in Northern Sonora. Impact Silver’s Zacualpan District veins are probably better ascribed to intermediate sulfidation epithermal mineralization, reporting this week results from the newly tested La Luz and San Antonio veins.

The Avino drilling results by Avino Silver & Gold Mines come from the main structure that has been subject of intermittent mining for several decades. Avino has been testing the structure to depth, now to 600 m below the surface, and 800 m along the dip of the structure. The company is trying to establish whether or not the mineralization at depth is related to a porphyry copper system, and if the changing metal ratios support the case.
