In 1916, the Teck-Hughes Mine built a 50-ton cyanide mill after the No. 1 shaft reached a depth of 500 feet. In 1923, the company was reorganized as Teck-Highes Gold Mines Ltd, which included the Orr claim to the south. The central shaft reached a depth of 2980 feet and a south shaft was sunk in 1928 to reach a depth of 3600 feet. A 1000-ton per day mill was in operation by 1930. High-grade ore of up to 1000 feet was found on six levels.
