Troitsa Epithermal Au-Ag

Troitsa Epithermal Au-Ag

  • Located in the Tahtsa Porphyry Belt west-central BC, 14 kms southeast of Huckleberry Cu-Mo Mine
  • Widespread epithermal Au-Ag veining and breccia cluster around the Moraine rhyolite complex consisting of a central dome with proximal to distal pyroclastic breccias and lapilli tuffs
  • Mineralization occurs in quartz-sulfide veins, stockworks and silica-sulfide flooded breccias associated with strong silica-clay-pyrite alteration and northeast-trending faults
  • Three zones with significant Au-Ag values are associated with the high-level rhyolite volcanic center:
    • Moraine
    • Wolverine
    • Dexter

Moraine Zone

  • The Moraine Zone, is a 2.3 km-long belt of epithermal quartz veining centered on a brecciated, QSP altered rhyolite dome

  • Soil sampling (1983) outlined a 950 m-long anomaly centered on the rhyolite, with up to 120 ppb Au and 8.6 ppm Ag, with 6500 ppm Pb, 2500 ppm Zn and 450 ppm Mo

  • Rock sampling (1983 & 2009) from the veins and mineralized breccia assayed anomalous to 5.9 g/t Au and 4,120.0 g/t Ag
Dexter Zone
  • The Dexter Zone is a new zone, not documented by historical work

  • Strong silica-pyrite alteration in a rhyolite clast breccia returned up to 5.2 g/t Au in limited sampling
Wolverine Zone
  • Dome-proximal breccia; oxidized hydrothermal breccia 0.22 g/t Au, 82 g/t Ag

  • Pervasive silica-pyrite 0.13 g/t Au, 22 g/t Ag, 0.108% Mo; epithermal quartz vein
