Mercedes is a 2000 tonnes per day underground gold-silver mine located in the State of Sonora in northern Mexico solely owned by Premier.
Several mining methods are utilized on the Property including cut-and-fill and bulk methods. Since acquiring the mine, cost reduction and increasing efficiencies and through-put has been a primary focus.
Several exploration targets exist on the Project that the Company has identified to extend the mine life. In addition to identifying potential targets close to existing infrastructure on the Property, the focus for 2019 will be to test along the several kilometres of the unexplored main northwest vein systems that the existing mines sit on as well as other regional targets.
The Mercedes Property is located 250 kilometres northeast of Hermosillo and 300 kilometres south of Tucson, Arizona. Power supply to the mine is provided by a 65-kilometre, 115 kV power line, from the town of Magdalena de Kino.
Located within two northwest trending anticlines, the andesite sequence hosts all the economically important epithermal veins and Au-Ag resources identified on the Mercedes Property. Gold-silver mineralization on the Mercedes Property are epithermal low sulphidation. A total of 14 fissure vein zones with a cumulative strike length of 12.35 km of gold-silver-bearing veins occur over a vertical range greater than 600 metres, length from 100m to 3km. Gold and silver-bearing vein/stockwork zones (up to 100m width) occur at Diluvio.
