A gold mine 2 miles SW of South Porcupine in the city of Timmins. The ore is hosted by Keewatin basalts, Timiskaming sediments and Kenoran porphyry. Gold occurs primarily in cross-cutting quartz veins and in ankerite-quartz-tourmaline veins which parallel the trend of the country rock. Tellurides are present in minor amounts. Silver is recovered at a ratio of 1 oz. of silver for each 6 oz. of gold. Of the sulphides, pyrite and/or pyrrhotite are dominant, however chalcopyrite, sphalerite, and galena are considered good indicators of gold. Minor scheelite is found in association with the porphyry ore.

The mine has been in operation since 1910.
