Capsule Geology

Two showings of molybdenite with chalcopyrite occur as fracture plane fillings and disseminations within quartz monzonite of the Cretaceous Raft batholith, just east of Double Lake, which is about 2.2 kilometres west of Patricia Lake and 10 kilometres south of Mahood Lake. The claims were originally part of the Aku (092P 023), SL, Mad and Nod claim group, which were staked as a result of molybdenum anomalies from a stream sediment sampling program done by Noranda in 1966. In 1974, Amoco conducted geochemical and geophysical work over the Wap claims which included the Double Lake showings and the Aku showings. In 1978, the two showings were staked as the Moly property by Kaare Peterson and Magnus Bratlien. In December of that year the claims were optioned by the Lorado Mining Corporation. In 1979, Lorado conducted a trenching program on the hillside about 700 metres east of the north end of Double Lake. Molybdenite was found in the trenches. They also did four short x-ray drill holes, geological mapping and prospecting, geochemical surveys and 11 percussion holes for a total of 683 metres on the KM 1-4, Moly and Far claims. Lorado changed its name to Norsemont Mining Corporation in January 1980.

All of the rocks found in the trenches are pink pegmatitic quartz monzonite. The rocks have been fractured and faulted. The faults in the trenches strike 200 degrees and dip east 35 to 90 degrees. The fractures generally strike at 020 to 110 degrees, with vertical dips. The molybdenite and chalcopyrite are associated with pyrite and limonite. In the east-striking set of fractures, a few quartz stringers were found to contain some specularite (Assessment Report 1013).
