Location Method: Data Compilation
Access Description: The occurrence is located about 97 km west-southwest of Pickle Lake and 3.4 km northeast of the First Nation Community of Slate Falls. Access to the occurrence is by appropriately equipped aircraft to North Bamaji Lake. About 2 km east of the First Nation Community of Slate Falls is a north-trending bay of North Bamaji Lake. A foot trail leads from the north end of this bay north and east to the occurrence area. A winter road along the Ear Falls to Pickle lake power corridor passes about 2 km south of the occurrence.
1965: Claims were staked on this occurrence and transferred to Dome Exploration (Canada) Ltd. 1966: Dome Exploration Canada Ltd. did considerable trenching on the claims before transferring the claims back to a Mr. Sanderson of Balmertown. 1966: Cochenour Willans Gold Mines Ltd. acquired an option on the claims and did a diamond-drilling program of 9 holes totalling 447 m. 1980: St. Joseph Explorations Ltd. staked claims covering the occurrence and did geological mapping and geophysical surveys. 1981: St. Joseph Explorations Ltd. did more geological mapping and geophysical surveys. They also did orientation soil geochemistry surveys, trenching and staked additional claims. 1984: Sulpetro Minerals Ltd. (name changed from St. Joseph Explorations Ltd.) did 14 diamond-drill holes totalling 2235 m on their claims. The post-1984 exploration history of the area is summarized by Nelson (2002).

Jan 16, 2007 (Mark Puumala) - The L15 Zone consists of multiple east-west-striking vertical shear zones that are up to 1 m wide. The mineralized zone has been traced for a strike-length of approximately 400 m and occurs in mafic metavolcanic rocks and felsic porphyry dikes. The shear zone contains quartz veins and sulphide mineralization consisting of pyrite, chalcopyrite and sphalerite (Parker et al. 1995). Biotite, sericite, carbonate and talc alteration is also reported by Nelson (2002). Significant assay results include 7.3 g/t Au and 229 g/t Ag, with elevated concentrations of Sb (2153 ppm), Cu (4342 ppm), Zn (1166 ppm) and Pb (3653 ppm) reported by D'Silva and Parker (2000).
