Exploration History

pre-1912: Cornelius Hunt - discovered molybdenite. 1912-1914: F.R. Aufhammer: property optioned then sold to Algunican Development Company; DD, underground development. 1915-1918: Renfrew Molybdenum Mines Limited: mine in operation Work done - approximately 1,800 to 2,000 feet of cross-cuts and drifts on four levels between depth of 10 and 150 feet, connected by about 230 feet of raises and shafts. Also 400 feet of drifts were widened into stopes from 20 to 25 feet wide. 1965: New Far North Exploration Ltd - self potential survey. 2008-09: D. Lalonde - ground geophysics, prospecting, sampling.

Lithology Comments

May 02, 2011 (A Wilson) - The marbles are coarse-grained white rocks composed essentially of calcite and/or dolomite with variable amounts of white mica, quartz, and diopside. The pegmatite is a massive, coarse-grained, (3 mm), pink rock composed of a mixture of quartz, microcline, plagioclase, and minor magnetite. The biotite gneiss is a strongly foliated rock composed of fine-grained biotite, quartz and feldspar. The amphibole gneiss is similar, except for the presence of amphibole. Hedenbergite gneiss is reported to be exposed on top of the ridge and is "well-foliated, medium-to-fine-grained, dark green rock which consists entirely of scapolite (mizzonite) and hedenbergite, with only small amounts of sphene, pyrrhotite, and apatite". The pyroxenite skarn is a massive, coarse-grained, dark green rock that consists essentially of diopside and minor scapolite, tremolite, and microcline, and locally abundant pyrite and pyrrhotite. Pyroxenite skarn zones containing disseminated molybdenite, pyrite, and pyrrhotite are developed in the marble along the contact with the pegmatite and a few metres away from the contact.

Mineralization Comments

May 02, 2011 (A Wilson) - Mineralization consists of erratically dispersed coarse flakes of molybdenite, usually associated with massive lenses of pyrite and pyrrhotite, contained within two stratabound bodies of pyroxenite skarn. The upper mineralized zone is reported by Eardley-Wilmot (1925) to average about 2 metres in width, has been traced along strike for about 120 metres, and has been proven downdip for a depth of 45 metres. The dimensions of the lower zone are uncertain. According to Eardley-Wilmot (1925) the lower zone is the richest and good ore was still present when mining operations ceased, but no estimates of grade or tonnage are available.
