NTS Grid: 41O09SE
Point Location Description: A 3x4m water filled pit supposedly 6m deep besides the old portage on a banded iron formation
Location Method: Field Visit with GPS
Access Description: The easiest access to the area is via Opeepeesway Lake to the old portage on the Little Rush River. The boat launch for Opeepeesway Lake is at the old Jerome Mine.
1907: Mr. Leith explored the iron formations in the area for their iron potential on behalf of other interests. It was probably during this period that a short shaft was sunk on the iron formation. 1963: Denison Mines carried out a geological mapping and ground geophysical survey which covered the area just north of the prospect. 2007-2008: Augen Gold Corp. : airborne electromagnetic, aeromagnetic and radiometric surveys; performed prospecting and sampling

Dec 07, 2005 (S Fumerton) - The banded iron formation consists of thinly bedded chert, graphitic shale and some carbonate beds. The beds are between 2 and 10cm thick with a strong hematite stain on the weathered surface.

Dec 07, 2005 (S Fumerton) - The iron formation is very lean and thin remobilised veins of massive fine grained pyrite occur adjacent to the chert beds within the shale beds. These veins are largely parallel to the bedding but locally discordant at a shallow angle. Pyrite forms about 10% of the rock and the iron formation is approximately 10m thick.
