Exploration Projects
Silverstone earned a 100% interest in three advanced silver-gold projects as well as two joint ventures in west-central Mexico, which together have historic resources of more than 75 million ounces of silver. These properties are located in Durango and Sinaola States, near the Pacific coast. Copala The Copala deposit covers 6,065 hectares, about 60 km ENE of Mazatlan. The property is bisected by the Durango-Mazatlan Highway. Major and secondary powerlines cross the property and water is abundant. There is an existing plant and tailings site and two independent mills are close to the historic working. The Copala property hosts more tha 7 NW striking vein systems each with more than 2 km of strike lenght within the property. Drilling has been focused on zones of historic workings on the Animas-Refugio and La Colorada veins systems. Mapping and surface sampling on the Cordon de Oro vein system is complete. Property-wide stream sediment program in progress. Latest News Release
Claudia The Claudia deposit covers approximately 6,390 hectares and lies 135 kilometers from Durango City, with good access via a paved highway. There are three main veins called Guadalupana, Aguilarena and Santiaguera that strike NS to NW. The veins converge in the Lizeth area were stockwork quartz veining anomalous in gold indicates potential for significant mineralization at depth. Promontorio (JV with Mega Silver) The Promontorio property covers 2,188 hectares and is located 140 kilometers north of the city of Durango. Its extensive vein system includes two main veins, Promontorio and Periclos, with an estimated historic production of 250,000 tonnes of 3,500 g/t silver and 20 g/t gold. Promontorio’s high-grade epithermal veins are traceable for more than 2 kilometers. Montoros (JV with Mega Silver) The 2,147-hectare Montoros deposit is 190 kilometers northwest of Durango City. To date, it has seen only partial exploration of four main epithermal vein systems, with vein widths locally up to 25 meters. Sampling in trenches, old mine workings and outcropping veins has returned positive exploration results.
