SILVERIA – MINING HISTORY AND GEOLOGY

Employed 420 minersArea mined 1960 to

1991Four historic mines, two

major operationsIP studies 1968No exploration drillingUnexplored IP Anomaly

SILVERIA – Past Producing & New Veins Identified 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.

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.
