(TSXV:RDU) (OTC:RDUFF) is pleased to announce that the Company has entered into an option agreement with a local concession holder to acquire a 100% interest in a 300 hectare property covering an historic silver mining camp located in Chihuahua, Mexico. \n\n\n \nPlata Verde\n\n\n \nAt the new project, named Plata Verde, Radius geologists have re-discovered an undocumented large scale underground bulk mining operation where in the late 1800's, historic miners hand excavated an extensive series of anastomosing caverns, producing silver bars at an associated smelter operation. The project appears to be un-explored since the miners ceased their operations, and no references have been found within the Mexican Geological Survey. The few local residents have no knowledge of exploration companies working in the area and there are no indications of prior exploration within the mines or surrounding outcrops. Initial prospecting rock chips by Radius geologists have returned silver grades between 5 and 1070 g/t Ag.\n\n\n \nLocation\n\n\n \nThe Plata Verde project is located in Chihuahua, Mexico, north of Radius Gold's Amalia Gold-Silver project and east of the historic Batopilas silver mining district (1708 to 1920) which reputedly produced over 300 million ounces of silver from high grade veins and structures. The property is accessible by road, with a 4 hour hike required to access the historic mines.\n\n\n \nGeology and Mineralization\n\n\n \nAt Plata Verde, silver mineralization occurs as massive to crustiform banded barite calcite with silver chlorides, sulphosalt minerals and native silver infilling and cementing fractures and breccia within a basaltic/andesite extrusive volcanic. The basaltic/andesite host occurs at the base of the Upper Rhyolitic Volcanics of the Northern Sierra Madre. In general the host volcanics and associated silver mineralization is covered by the overlying rhyolitic ignimbrites and is only exposed along the length of a small creek. \n\n\n \nOn the eastern side of the creek a number of small entrances, hardly visible, lead to an extensive network of anastomosing mining tunnels and cavities. The mining and excavation was done by hand with hammer, ch...
