The Coulotte showing is located about 70 kilometres southeast of the town of Fernie. The showing area is underlain by undivided strata of the Helikian Purcell Supergroup consisting of Nicol Creek, Sheppard, Gateway, Phillips, and/or Roosville formations. Undivided Upper Purcell sedimentary strata correlates with the Dutch Creek Formation.

Copper, as chalcopyrite, or chalcocite and bornite, is present in widespread small occurrences throughout the region often associated with quartzitic phases of the sediments, and in many cases with the dikes and sills. Mineralization occurs as disseminations and fine fracture fillings in quartzite beds, in shales, and to some degree in dioritic dikes and quartz vein material. Argillites appear to favour the chalcocite-bornite association.

WORK HISTORY

From 1968 to 1969, Akamina Minerals Ltd. conducted a regional mapping and geochemical program on the "Grinnell Formation", a section of which underlies the claims held by Mark V and Thor Explorations around 1970 (Assessment Report 3336). Widespread occurrences of copper mineralization were located in the Grinnell and neighbouring formations. Some of these were trenched. Most of the resulting assays appear to have been in the 0.2 to 0.9 per cent copper range, with occasional grab samples assaying up to 5 per cent copper (Property File Document 810672). The mineralization is reported to have occurred as disseminations and fine fracture fillings in quartzite beds, in shales, and to some degree in dikes and quartz vein material.
