Exploration History

1896: Property was owned by R.H. Ahn and Company of Rat Portage. Work began in October and “ore” was stockpiled. 1897: “Ore was shipped to the Rat Portage Reduction Works. 1936: Property was staked by Rhond Prospectors Syndicate. 1986-87: Noranda Exploration Company carried out grab and channel sampling. 1988: Noranda conducted a magnetometer and VLF-EM survey.

Lithology

Lithology Comments

May 14, 2020 (Therese Pettigrew) - The area is underlain by mafic and felsic volcanics, which probably are equivalent to the upper mafic and lower felsic sequences of Shoal Lake. The Canoe Lake quartz diorite stock lies about 200 m south of the No. 2 shaft and the contact extends east, parallel to the shore of Echo Bay. Foliation in the volcanic rocks strikes within 10 degrees of 095 degrees and dips near vertical. The mafic rocks are mainly fine-grained flows and the felsic rocks are mainly tuffs (Davies and Smith, 1988).

Mineralization

Mineralization Comments

May 14, 2020 (Therese Pettigrew) - The No. 2 Vein was "crosscut" across the 26 m "vein" to a depth of 3 m and a shaft was sunk at one end (Blue 1896). Assays of from $6 to $15 Au/ton (0.3 - 0.75 oz/ton) were reported from a 60 ton "ore" pile (Blue, 1896). At the shaft, there is a quartz vein, up to 20 cm wide, in a shear zone that is east of the contact between mafic and felsic volcanics. This vein strikes 105 degrees and dips vertically, and is weakly mineralized. A small "ore" pile nearby indicates that vein quartz up to 30 cm wide contains iron carbonate, chalcopyrite, pyrite, sphalerite, galena and arsenopyrite. Dump rocks are mainly foliated basalt containing fine pyrite and pyrrhotite; they typically contain carbonate and are cut by carbonate veins. A grab sample taken in the 1988 study of mineralized white quartz, with carbonate, contained >10 ppm Au, 61 ppm Ag, 390 ppm As, 0.28% Zn, 0.25% Cu and 44 ppm Pb. A grab sample of foliated, mineralized basalt returned 2 ppb Au (Davies and Smith, 1988). Grab samples collected by Noranda in 1987 returned assays up to 2.74 g/t Au and 39.42 g/t Ag (Assessment report 52E10NW9471).
