This is a Gold-Tungsten deposit on the south side of Brandywine Creek, opposite the Silver Tunnel,which is a different vein system, but still on Van Silver property.
The Quartz Tunnel is on the same property (Van Silver’s Brandywine claims) as the Silver Tunnel that produced a fairly extensive suite of rare, complex, silver sulfide micro-crystals (Woodside et al. 2000). The Brandywine claims cover a portion of the contact between Jurassic to Tertiary plutonic rocks of the Coastal Plutonic Complex and an over¬laying roof pendant of Lower Cretaceous Gambier Group volcanic and sedimentary rocks. In contrast to the rhyolite- hosted quartz veins of the Silver Tunnel, the Quartz Tun¬nel ore occurred in a diorite-hosted fissure in mineralized quartz bands and stringers.
A small number of gold specimens were found in an ore stockpile a short distance outside the tunnel in vuggy quartz matrix (Lloyd Twaites and Ty Balacko, pers. com., 2005). The gold is associated with pyrite, sphalerite, scheelite, and hubnerite. Several well-developed gold crystals, to 0.5 mm, showing dominant octahedra with cube modifications have been found so far. Hopper features on the corner (octahedral) faces are evident on one crystal.
