Capsule Geology

The Blackfly (Area 21) occurrence is located in the eastern headwaters of Dion Creek, a tributary of Charcoal Creek, at an elevation of approximately 1500 metres.

The area is underlain by schist and amphibolite of the Hadrynian and/or Paleozoic Silver Creek Formation (Mount Ida Group). These have been intruded to the south and east by Cretaceous granodioritic intrusive rocks.

Locally, pyroxene hornfels- altered quartz monzonite and aplite host thin, 0.1 to 5 centimetre wide, quartz-carbonate-sulphide veins and stock works. In 2010, a sample (BF-4) assayed 0.72 gram per tonne gold, 94,700 grams per tonne silver and 47.8 per cent lead (Assessment Report 32613). In 2013, a sample (189) assayed 2670 grams per tonne silver and 0.528 per cent lead (Assessment Report 34225).

Another area of mineralization, referred to as the North zone, consists of a granite gneiss and carbonate-biotite gneiss/schists and hosts disseminated molybdenite and fluorite. In 2010, a sample (DH-3A) assayed 0.195 per cent molybdenum (Assessment Report 32613). In 2013, a sample (MBC) assayed 210 grams per tonne silver and greater than 1.0 per cent tungsten (Assessment Report 34225).

In 2005 and 2006, the area was prospected as the Valley claims. During 2010 through 2016, the area was prospected and sampled as the Blackfly Gulch property.
