Exploration History

1944: Gold was discovered on the west end of East Island by Noranda prospectors. Trenching and sampling was conducted, as well as a 6 hole x-ray diamond drill program. 1974: the property was optioned by Roy Martin to a joint venture consisting of Noranda, Newcnex, and Tombill Mines. The JV conducted geological mapping. 1975: the joint venture conducted geological surveys and drilled 7 DDH totalling 614.5 m (6 of the holes on the East Island showings). 1982: Barrier Reef Resources optioned the property from Roy Martin. 1983: Barrier Reef drilled 7 DDH totalling 1181.7 m across Hay Island, East Island, and the intervening lake bottom. A lake bottom survey was carried out to detail the topography and recover lake sediment samples. 1986: Laramide Resources Ltd. conducted trenching and sampling. 1987: Laramide conducted magnetometer, VLF-EM, and IP surveys. 1991: Rio Algom drilled 1 DDH totalling 310 m.
