Point Location Description: LOCATED 7.8 KM DUE SOUTH OF BORUPS CORNERS, 52 KM EAST OF DRYDEN ON HWY 17
Location Method: Field Visit with GPS
Access Description: The HW 479 occurrence is located 52 km east of Dryden on Highway 17. From Borups Corner, drive 9.6 km south on the Sandy Point road then turn easterly onto a gravel road, and proceed about 1.5 km. A shaft is sunk on one of two quartz veins. (OFR 5731, p. 85)
1898: John Maw and S.O. Greening sunk a shaft to a depth of 40 feet (Bow 1899). 1983: Teck Exploration performed ground VLF-electromagnetic and magnetic surveys and a geological mapping over claims that included the H.W. 479 occurrence (Assessment Files, Resident Geologist's Office, Kenora). 1984: International Platinum Co. optioned the property from Alex Kozowy, and as of February, 1990, continue to hold the option.

Jul 18, 2022 (Q Unknown) - The occurrence is underlain by mafic metavolcanic rocks of the Kawashegamuk Lake group (Kresz 1987). Two parallel undulating quartz veins 62 metres apart strike about west-northwest. The subtle vertically-dipping shear zone at the more southerly of the two veins strikes 135°, but the quartz vein strikes 110° and dips 73° to the north, with left-stepping portions striking 055°. These represent oblique and extension veins respectively. Kinematic indicators such as lineations plunging 43° towards 300°, the S-shape of the quartz vein and the left-stepping attitude of the quartz vein suggest a sinistral, oblique-slip sense of movement in the shear zone. The more southerly quartz-carbonate vein is medium to dark grey, to whitish in places. The vein is opaque to cloudy, with a granular texture, with some ribbons of chlorite. Mineralization consists of up to 3% chalcopyrite, and traces of pyrrhotite and bornite. The vein is exposed over a 27 metre length, and varies in width from 10 cm to 2.5 metres. The second quartz vein, 62 metres north of the shaft, trends at about 120° and dips 74° to the north. It is exposed over an 11 metre length, and varies from 20 - 50 cm in width. It shows the same structural features as the southerly vein. A contorted narrow felsic dike occurs close to the quartz vein. Three grab samples were taken by the author from the south vein and one from the north vein. Analytical results indicate that the amount of gold is related to the amount of copper. The best sample returned 530 ppb gold on analysis. (OFR 5731, p. 85-89)
