The Kintla West Tributary showing is located 87 kilometres southeast of the town of Fernie. The showing is underlain by dolomite and dolomitic siltstone of the Helikian Kitchener Formation, Purcell Supergroup.
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. Much of the host stratigraphy was historically reported as being Grinnell Formation.
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 starting in 1970. 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.
In 1971, soil geochemistry and geological mapping was completed and approximately 240 samples were collected on behalf of Mark V Mines Ltd and Thor Explorations Ltd. Several anomalous zones were recorded on the ABC, DEF, GHI, and JKL claims and the ABC, DEF, HIJ, and JKL claims covered a number of showings from Commerce Peak through Sage Creek and south to Starvation Creek. Reference and maps show copper mineral locations from their claim area east to the Alberta border (Figure 3, Assessment Report 3336).
