Point Location Description: Transfer
Location Method: Conversion from MDI
Access Description: Proceed west along Hwy 11-17 to Hwy 588. Turn left and proceed westward through Nolalu. At a distance of 4.1 km SW of Nolalu, a farmhouse is present on the right (north) side of the road. From this farmhouse, a skidder track proceeds northward for a distance of 200 m to the mine site on the banks of the Whitefish River.
1885: veins had already been discovered and were being developed. J. Woodside and J. Conmee led a contingent of owners. 1886: shaft sunk through vein material to a depth of 9.1 m before work was suspended due to lack of funds. Two trenches over 90 m were also developed. 1888: work recommenced. Shaft sank to a depth of 15.8 m. 1890: the mining location was offered for sale due to lack of funds to develop.

Feb 07, 2018 (Therese Pettigrew) - Bedrock exposure along the Whitefish River in Lot R135 shows the general geology of the area to be that of a massive Archean granite. The granite forms a narrow westerly-trending strip of exposure exactly following the Whitefish River. It pinches out to the east and connects to a much larger batholith to the west. To the north and south, chert, carbonate, and taconites of the overlying Lower Gunflint Formation are exposed.

Feb 07, 2018 (Therese Pettigrew) - In the central part of R 135, about 10 chains northwesterly from the bridge over Whitefish river on the Fort William-Whitefish highway, there is a tangle of veins 12 feet wide occupying a shatter zone in granite. The vein system is exposed over a length of 15 feet in the vicinity of a shaft. It trends south 30 degrees east and dips 80 degrees south. The vein material consists of white calcite, white and amethystine quartz, green and purple fluorite, galena, pyrite, and sphalerite. The pyrite occurs occasionally in peculiar ring-like or rather more hexagonal arrangement in the calcite, the centres of the rings, etc., consisting also of the latter mineral. The shatter zone includes blocks and small angular fragments of granite and Animikie iron formation. The vein lets that make up the vein system are for the most part less than 4 inches wide and within the width of 12 feet they make up approximately one-quarter of the total volume. The fluorite-bearing veinlets showing an imperfect banding have been dislocated by fractures that have been cemented by quartz and amethyst-bearing veinlets. The galena and sphalerite are sparsely disseminated through the fluorite-bearing parts of the vein (Tanton, 1931). A number of newspaper articles and mining review periodicals during 1886 reported very favourably on the appearance of the ore at the Partridge Rock site. The only recorded assay result observed, however, of the vein material near the location, stated that it contained no gold or silver (Ingall, 1888). It is probable, as is typical of this mining area, that mineralization is very localized and erratic.
