Exploration and development commenced about 1906 and was intermittent until the 1960s. The mineralization was explored via 2 shafts and an adit with 2 levels developed (Born and Hitch 1990).
Dec 22, 2011 (D Guidon) - The workings of both properties are located near the north contact of a near-vertical Nipissing diabase dike that cuts Cobalt Group sedimentary rocks. The group’s Lorrain Formation sedimentary rocks are composed of arkose. The diabase dike is about 100 m wide in the vicinity of the Edison and about 120 m wide at the Crescent. The dike dips at about 75 to 80 degrees to the north. The geology of the deposits is described in Born and Hitch (1990) and Born and Burbidge (1997). On the Edison, dump samples collected by Born and Hitch (1990) contained chalcopyrite, bornite, galena, erythrite and malachite. Analysis of 2 samples contained up to 3.09% copper, 23 560 ppm cobalt and 940 ppb gold. Two small parallel shafts, approximately 7 m apart, are located at 583347N 5246330N. Two samples were collected from the nearby rock dump. A sample of white calcite vein contained disseminated erythrite. The host is a green Nipissing diabase. The other sample contains chalcopyrite blobs up to 1 cm in size, some with nearby development of malachite and azurite. The matrix of the diabase near the vein contains 3 to 5% disseminated chalcopyrite and/or pyrite. About 75 m to the southwest is a trench in the bedrock with a small pit on each end. The pits are located at 583272E 5246294N and 583287E 5246289N. A sample of dump material contained a trace of disseminated sulphide and minor erythrite. Assay results were disappointingly low at 7 ppm silver and 1 ppb gold.
