In 1915, 16 tons grading 0.84 percent MoS2 was shipped to Ottawa. Between 1916 and 1918, 19,949 tons of material was mined and total concentrates produced amounted "to 96,990 pounds, 85 percent of which averaged about 95 percent MoS2.(MDC007)

Pegmatite in marble. 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. (ARV53)
