1948: The property was staked in 1948 by D. Olson of Red Lake and V. McKey of Balmertown had half interest. At least three pits were blasted. '63-'72 Cochenour Willians Gold Mines Ltd conducted programmes. 2000: reconnaissance mapping and geochemical sampling programme was initiated on the property, exploration program resulted in stripping, sampling and detailed mapping project and drilling program was completed in the fall of 2000 by Goldcorp Inc.

Belt: Red Lake
Geological Age: Archean
Metamorphism Type: Regional
Metamorphism Grade: Amphibolite
Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The stratigraphic succession in the vicinity of the prospect is comprised of mafic flows at the base, overlain by thin units of black carbonaceous sediments which are in turn overlain by argilleous sedimentary rocks. The sedimentary rocks are overlain by a thin unit of mafic flow breccia and oxide facies iron formation. The uppermost unit is comprised of mafic flows. Rock units strike NW-SE and dip to the NE. Stratigraphic tops are to the NE. The volcanic and sedimentary rocks have been intruded by several differentiated gabbro sills. Metamorphic grade in the area has attained amphibolite facies. Mineralization is hosted in a sheared and altered ultramafic sill in iron formation. DEPOSIT DESCRIPTION: The occurrence is located in a gabbroic unit and mineralization consists of pyrrhotite, chalcopyrite and pyrite.

Dec 07, 2005 (K R Kettles) - MDI1 DATA: GRADE - 1948 - PIT SAMPLES: PIT#1: 0.018%CU, #2:0.32%CU,0.01 OPT PT, #3: 0.028%CU. NI NIL IN ALL 3 PITS., GRADE - 1949: QUALITATIVE TESTS FOR NI REPORTED POSITIVE BY CHISHOLM Grab samples taken from the three pits returned the following assays: PIT 1: .018 % Cu nil % Ni* - Pt (oz/ton) PIT 2: .32 % Cu nil % Ni* 0.01 Pt (oz/ton) (0.343 g/tonne) PIT 3: .028 % Cu nil % Ni* - Pt (oz/ton) * Chisholm reports that qualitative tests for nickel (dimethyl glyoxime test) gave positive results for all three samples. Mineralization is hosted in a sheared and altered ultramafic sill in iron formation.: The occurrence is located in a gabbroic unit and mineralization consists of pyrrhotite, chalcopyrite and pyrite.
Dec 09, 2011 (A McKee) - Grab and Trench samples taken, various samples, Ag ranging 1-3 ppm, Ni 420-860 ppm, Cu 470-1440, Pt 15-40 ppm
