Comstock Geology Overview (Gold-Rich VMS & Porphyry Potential)
3,610 contiguous hectares
The property lies within the Western Belt of the Nicola Volcanic Group at the south-western extent of the Quesnel Terrane. The property sits near several prominent epithermal and porphyry deposits within the Nicola Group including Highland Valley Copper Mine, New Craigmont Mine, New Afton Mine, and the Copper Mountain Mine.
The geological setting of the Comstock Property allows for the potential of both volcanogenic massive sulphide deposits from the period of the Nicola arc emergence as well epithermal and porphyry deposit potential from its geographic location to intrusive bodies related to know porphyry-type mineral deposits.
A recently completed comprehensive geophysics program has identified anomalies below historic shallow drilling completed in 1988, revealing the potential for a porphyry system at depth. Historic drilling on the Comstock property was limited to 60m and ended in mineralization.
Additionally, recent geophysics (radiometrics) has identified the presence of a second, large rhyolite zone with Ag-Pb-Zn mineralization, further demonstrating a known, typical component of historic dual Au-rich VMS & Porphyry deposits (illustration below).
