The Coquihalla Mountain area lies within the greater Upper Tulameen Mining Region of British Columbia, and represents one of the older hardrock mining camps in the southern west-central sector of the province. The area’s mineral resource was first discovered in the early part of the last century by prospectors seeking the source of the placer gold and platinum found in the Tulameen River and associated tributaries. Hardrock prospecting in the Coquihalla Range is recorded as early as 1913, with limited early production. Over the years following, changing world times, such as wars and the Great Depression, coupled with decades of low gold prices, served as the main contributors why most of better prospects had not been developed. However, with the upswing in the precious metals market, renewed interest has been generated and most of the better properties have long since been locked up by a variety of mining entrepreneurs, from individuals to large companies. please direct all inquiries to: COQUIHALLA MOUNTAIN GOLD~SILVER~COPPER PROPERTY

Capsule Geology The Superior occurrence is underlain by sediments of the Lower to Upper Cretaceous Pasayten Group which are comprised of altered, fractured and fissured sandstone, conglomerate and pelite. These are intruded by diorite of the Late Jurassic and Early Cretaceous Eagle Plutonic Complex. To the north of the showing, the Upper Oligocene- Lower Miocene Coquihalla Formation comprised of basalt, rhyolite, tuff and agglomerate, caps Coquihalla Mountain. The showing consists of a quartz vein which infills a fracture zone in the schistose rocks, nearly paralleling a diorite contact some 9 to 10 metres distant. The vein consists of quartz stringers within silicified and altered rock which attain a width of about 30 centimetres. The quartz hosts galena, pyrite, chalcopyrite and tetrahedrite. There is a 25-centimetre gouge, or talc-rich zone, on the hangingwall of the vein. The main workings consist of an opencut 31 by 4.5 by 1.5 metres in which about 27.2 tonnes of high-grade ore was mined and then lost by a flood. In 1913, a sample of the high-grade ore assayed 2.06 grams per tonne gold and 1151.98 grams per tonne silver. A 1.3-metre sample across the lower end of the cut yielded trace gold and 20.57 grams per tonne silver (Minister of Mines Annual Report 1913, page 233). In 1984, silicification and pyritization was found to be associated with east-trending faults. A major fault of this nature was found along the western boundary of the claim. Ten samples were taken from the pyritized areas and assayed between 0.34 and 1.71 grams per tonne silver and 0.034 gram per tonne gold (Assessment Report 12390).
