The Fire Mountain Property is comprised of seven (7) mineral claims (MTO) containing 93 cell claim units totaling 1937.03 hectares. The property was originally staked, May 17, 2012. The property is accessible by air. It can also be reached via road, approximately 200 kilometres from Pemberton and the Lillooet River Road. The property has been the focus of several technical reports. Please see the bottom of this section for a link to our report.
The property is underlain by the Fire Lake Group. The Fire Lake Group represents an island arc sequence preserved as a roof pendant within intrusives of the Coast Plutonic Complex. The assemblage has been subjected to thrust faulting, large amplitude folding, and regional metamorphism up to greenschist facies. The Harrison Lake shear zone occurs to the east, in the Lillooet River Valley, which is known regionally to be an important control to mineralization. Diverse styles of mineralization are found in the Fire Lake Group. These include syngenetic volcanic-exhalative mineralization, granodiorite-related stockworks and breccia zones, high angle thrust-related mesothennal gold-copper veins, and late, fault-related epithermal mineralization. The rocks of the Fire Lake Group have been correlated with those of the Gambier Group, host to the Britannia copper-zinc-silver-gold volcanogenic massive sulfide deposit. The Britannia deposit, situated about 65km to the west-southwest of the property, yielded approximately 47.8 million tonnes of ore grading 1.1% Cu, 0.65% Zn, 6.8 g/t Ag and 0.6 g/t Au between 1905 and 1977.
The Fire Mountain property covers a part of the Fire Lake pendant, one of several scattered Jurassic-Cretaceous pendants located in the southern Coast Mountains. The pendant is surrounded by plutonic rocks of the Coast Plutonic Complex. Rocks within the pendant are termed the Fire Lake Group and are correlated with the Gambier Group, based on lithological similarities. This correlation is important from a mineral potential perspective, since it suggests the potential for volcanogenic massive sulphide mineralization in the Fire Lake Group. The Britannia Mine near Squamish, approximately 65km west-southwest of the Fire Mountain property, is an example of massive sulphide mineralization within the Gambier Group. The Britannia Mine produced approximately 47.8 million tonnes of ore grading 1 .l% Cu, 0.65% Zn, 6.8 g/t Ag and 0.6 g/t Au between 1905 and 1977. At the time of the mine closure, drill indicated reserves were 1.4 million tonnes grading 1.9% Cu. Lynch describes the Fire Lake and Gambier Groups as collectively being included in the Nooksack tectonostratigraphic terrain, regarded as part of a broad Upper Jurassic-Lower Cretaceous overlap assemblage which links Wrangellia in the west with Stikinia to the east, by latest Early Cretaceous time.
British Columbia Properties | The Cariboo gold belt in south-central British Columbia was a world-class producer of gold. Historic gold production in the Cariboo area was approximately 3.8 million ounces, 2 million from placer operations and 1.8 million form lode deposits. These totals are an estimate only as prior to 1874 production was not recorded. 90 percent of the placer gold was recovered from Late Pleistocene, pre-glacial and interglacial gravels in buried paleo-channels of modern stream valleys. In addition, the placer operation from the Bullion pit at Likely produced 175,000 ounces of gold and 1,800 ounces of platinum. Gold and platinum were also reported in placers in the Frank Creek area in similar proportions.
