Province: Southern
Subprovince: Cobalt Basin
Supergroup: Huronian Supergroup
Geological Age: Paleoproterozoic
Jun 25, 2010 (G Bennett) - The rocks in the vicinity of the mine wokrings consist of gently dipping sediments of Upper Huronian age cut by small amounts of Keweenawan diorite or diabase. Steeply dipping surface drill holes in the vicinity of the west vain show that the country rock is almost entirely bedded cherty quartzite cut bynarrow diabase dikes. A peculiar feature of the quartzite is a spotted alteration identical in apperance to that found in the Huronian sediments of the Cobalt Silver Camp. This green spotted alteration is not confined to any particular beds but appears to be rather uniformly distributed throughout the bedded quartzite. Fragments of the spotted sediments are found in the copper-bearing veins, indicating that the alteration is pre-ore. It does not seem to have any relation to copper mineralization.
Jun 25, 2010 (P Beach) - Fissure filling qtz-carbonate veins containing cp, specularite, bornite and chalcocite cut Proterozoic cherty quartzite (Gordon Lake Formation). Two principle veins, are known as the East and West veins. East vein strikes N80W, dips 90, has a known length of 850 feet, and an average width of from 2.5 to 5.0 feet. It was developed by an adit 1040 feet long. West vein strikes N70E, dips 90, and is developed by an adit 1368 feet long. Crosscuts and some stoping from the West adit.

Jun 25, 2010 (S Butorac) - In 1948: 3479 tons ore milled averaged 3.74% Cu and 28.9% Cu produced. In 1949: 9,547 tons ore averaged 4.90% Cu; concentrate averaged 30.85% Cu. In 1983: ddh's by Canamax returned values up to 1200 ppm Cu over 30m.

Notes: The veins are fault-fissure fillings and have sharply defined walls. They dip almost vertically and so cut across the flat-lying sediments almost at right angles. The main vein filling is calcite, sometimes in very coarsely crystalline masses, with lesser amounts of quartz. Large vugs and druses are common in the veins. At many places quartz crystals line the walls of the vein. Fault breccias, showing fragments of the wall rock in the vein filling, are widespread. Chalcopyrite and lesser amounts of specularite occur in thecalcite-quartz gangue. Thechalcopyrite is spottily distributed along the veins. In the stope it was noticeable that where the vein narrowed chalcopyrite sometimes occurred across the full width but where it widened chalcopyrite tended to occur near the walls. The main source of ore in the west workings was a vein that branched from the adit vein a few feet above the level; it angled away from the adit going eastward. A short shoot with ore widths up to 25 feet was mined and parts of this were reported to be rich in chalcopyrite. Thesurface open-cut above the stope was opened for a length of 175 feet. The ore was mined by benching and passing it through a raise to the adit level. The vertical distance from the adit level to the surface of the open cut is in excess of 200 feet but the benching was only carried downward about half this distance. In places a 10 foot width of the open-cut would be much less. The is no ore exposed on the west adit level. The east vein outcrops along the top of a ridge that terminates abruptly at a cliff about 100 to 150 feet high near the shore of Cobre Lake. An open cut about 6 feet in depth has been made along the vein for the greater part of its exposed length, which is about 850 feet from the cliff edge. This vein varies from 2 1/2 to 5 feet in width and contains considerable chalcopyrite with accompanying secondary malachite, azurite, and bornite; specularite occurs with the chalcopyrite.
