SILVERIA – Past Producing & New Veins Identified l Economic mineralization on the Property

SILVERIA – Past Producing & New Veins Identified l Economic mineralization on the Property is related to ubiquitous NE to ENE steeply dipping quartz, carbonate, galena, sphalerite, chalcopyrite veins hosted within well‐defined fracture zones that formed in response to a regional scale tectonism. l The strongly mineralized zones within the veins (ore shoots) are sub‐vertical and according to historical cross‐sections, have vertical extents of more than 400 metres. The rock textures and metal zoning indicate an intermediate sulphidation environment. (Gilbertson and O’Donovan, 2008).
