Tough-Oakes produced 213 tons of high-grade ore in 1914. Operations included a five-stamp mill for amalgamation plus a cyanide plant. However, the presence of high-grade ore in the vein terminated at the 300-foot level and the mine shut down in 1918. This property was consolidated with Burnside's to form Tough-Oakes Burnside Gold Mines Ltd. in 1923 and the Burnside No. 3 shaft was deepened to 1000 feet. The operation went bankrupt in 1928. Operations restarted as the Toburn in 1932, as a subsidiary of the American Smelting and Refining Company.
