Miner Mountain Geology

The structure of the property is dominated by the northeast-southwest trending Boundary Fault, a west side down normal fault zone.
  • Miner Mountain is located along the same regional fault system as the producing Copper Mountain Mine (which are mining 0.33% copper with gold and silver credits)
  • Geologic setting and porphyry target are similar to Copper Mountain Mine as recently confirmed and reported by BC Geological Survey

Regional Geology

The Miner Mountain Property is located within the southern portion of the Quesnel Terrane, or Quesnellia, of the Intermontane Tectonic Belt of British Columbia. Quesnellia is a northwesterly trending belt of Upper Triassic to Lower Jurassic submarine and subaerial alkalic and calc-alkalic volcanic rocks, related sedimentary rocks, and comagmatic intrusive rocks some 40 to 50 kilometers wide and traceable from near the 49th parallel along the full length of the Intermontane Belt into the Yukon.

In southern British Columbia, this assemblage of volcanoplutonic arc rocks is known as the Nicola Group, a name derived from Nicola Lake near Merritt and coined by G.M. Dawson who in 1877 did the earliest geological work on these rocks. In northern British Columbia and Yukon these rocks are known as the Takla and Stuhini volcanoplutonic assemblages. These rocks are noted for their mineral deposits, principally copper-gold porphyry deposits, and copper and gold skarns.

Property Geology

The Miner Mountain property is on a large rolling plateau with a small peak at its southern end (Miner Mountain, Mt. Baldy) overlooking the Similkameen River and the town of Princeton.

The most economically important assemblages are the Nicola Group and associated intrusions. Mapping by in 2012 by the BCGS defined a series of volcanics, sediments and intrusives.

  • Volcanic Conglomerate-Siltstone : Grey-green, brown weathering with decimeter scale bedding, cross stratification, and graded bedding.
  • “Cherty Tuff”: Pale green-white siliceous volcanic siltstone, with centimetre scale bedding, locally graded.
  • Limestone, Carbonate Breccia-Conglomerate: Light grey-maroon hematitic massive recrystallized limestone.
  • Polymictic Lapilli Tuff: Grey to Orange weathering, massive to thickly bedded, with lapilli clasts in an arkosic matrix.
  • Pyroxene Phyric Volcanic Breccia: Pale Green with blocks of dark, coarse grained pyroxene-porphyry blocks and lapilli, in a crystal rich tuff matrix.
  • Hornblende-Feldspar Porphyry: Dark Grey blocky acicular hornblende-feldspar phyric breccia, lapilli tuff and flows.
  • Pyroxene Phyric Flow Rocks: Ochre – Grey sparsely amygdaloidal basaltic flow, with variable phenocrysts including, augite, glomeroporphyritic feldspar, and altered relicts of olivine.
  • Diorite: Tan-Green-Orange weathering, with leucocratic quartz bearing dyke phases, massive mineralized, hornblende diorite and possible microdiorite.
