Mercedes

The Mercedes Gold-Silver Mine is located in the state of Sonora, Mexico, approximately 250km northeast of the city of Hermosillo, within the prolific Mexican epithermal gold belt and surrounded by world class deposits like Cananea and Nacozari. Mercedes is owned and operated by Bear Creek Mining who, in April 2022, acquired the project from Equinox Gold Corporation.

Gold-silver mineralisation on the Mercedes property is hosted within mineralised epithermal, low-sulphidation (adularia-sericite) zones of veins, stockwork, and breccia zones. The mineralised zones range in width from less than one metre to composite vein/stockwork/breccia zones up to 15m wide. In the Diluvio zone, gold-silver bearing vein/stockwork zones locally attain thicknesses in excess of 100m. The length of individual veins varies from 100m to over 3km.

Mercedes is a fully mechanised, ramp-access, underground mine with five underground mining areas: Mercedes, Barrancas, Lupita, Diluvio and Rey de Oro. The process plant at Mercedes has a capacity of approximately 2,000tpd and is based upon conventional milling with Merrill-Crowe recovery of gold and silver.

As of 2022, over 550km of drilling has been completed on the property. This has resulted in the delineation of over 16.5km of veins within or marginal to andesite-filled basins, which constitute a primary exploration target on the property with much of the 692km2 land package untested.
