Capsule Geology

The Mike 30 showing is located at approximately 1830 metres elevation near Pollock Creek, a tributary of the Flathead River.

Regionally, the area is underlain by sedimentary and volcanic rocks of the Purcell Series, predominantly by consisting of Nicol Creek, Sheppard, Gateway, Phillips, and/or Roosville formations. Undivided Upper Purcell sedimentary strata correlates with the Dutch Creek Formation. Diorite sills have intruded several formations of the Purcell Series.

In 1970 and 1971, Alcor Minerals completed a program of stream sediment sampling, geological mapping, and prospecting. This work led to the discovery of the Mike 30 showing and Goof 30 (082GSE058) showing to the north.

In general, mineralization consisting of disseminated chalcocite, chalcopyrite and bornite is found within quartzite units. Malachite staining is common on surface exposures. Chalcopyrite, with pyrite and minor pyrrhotite, is concentrated locally along the margins of diorite sills of the Proterozoic Moyie Intrusions. Sample KH-19 consisted of chalcocite and minor malachite in argillaceous quartzite and sample KH-20 (30 metres east-southeast of KH-19) consisted of chalcocite, minor bornite and malachite in a 15-centimetre-thick quartzite bed. Mineralization was traced for 18 metres along strike though covered by much overburden.

WORK HISTORY

In 1970, Alcor Minerals Ltd. conducted mineral exploration on their North Kootenay Pass property which included stream sediment sampling and prospecting. Alcor's initial phase in August 1970 consisted of the collection of 231 stream sediment samples that were assayed for copper, lead, and zinc. These samples were also collected from Alcor's Commerce Peak and La Coulotte properties. No stream sediment anomalies were reported on the North Kootenay Pass property in 1970 though samples prospecting turned up mineralized samples KH-19 and 20 (Assessment Report 3160).

The second phase of Alcor's work was on the seventy Mike and Goof claims near North Kootenay Pass and was conducted in October of 1970 when a total of 40 samples of stream and spring waters were collected and analyzed for copper, lead, and zinc. The geochemical survey revealed several anomalous or slightly anomalous concentrations of zinc, but no anomalous concentrations of copper or lead were found though previous prospecting turned up mineralized samples as described above (Assessment Report 3161).
