Lake Shore Mines Ltd. was incorporated in Feb. 1914. Oakes proceeded with sending a crosscut from his shaft on the South Vein towards the anticipated Main Break under the lake to the north. This crosscut encountered high-grade ore and a 100-ton mill was in operation by March 1918. Their No. 1 shaft reached a depth of 1600 feet and their No. shaft a depth of 1000 feet by 1930 and was considered "the wonder mine" by Pain. There was 1600 feet of high-grade ore at the 1000-foot level and 2400 feet at the 2400-foot level.
