c. 1930s Canada 2 large panoramic photos Kirkland Lake ON gold mines
Two large panoramic photos of mines in the prolific Kirkland Lake gold district in Northern Ontario .Both taken by same photographer. Wright-Hargreaves Miners Photo of a large group of miners and management posing in front of building. Some have their lunch boxes, some wearing mining helmets. Labeled “WRIGHT HARGREAVES MINE, KIRKLAND LAKE ONT.” Photo has a vertical crack near right border 8” x 35” The Wright-Hargreaves Mine was one of the largest gold mines in the Kirkland Lake camp. It was in regular production from 1921 to 1964, with a total production of 4,821,296 ounces of gold at an average grade of 0.49 ounces per ton. The mine's production ceased following a serious rock burst underground in August 1964, and the processing plant was previously shut down in 1957. The mine's discovery and production played a significant role in the development of the Kirkland Lake Gold Camp and the Canadian mining industry. Lake Shore Mine Photo of the Lake Shore Mine site. Labeled “LAKE SHORE MINE, KIRKLAND LAKE ONT.” Photo has a vertical crack near right border, smaller one left border. 8” x 35” The Lake Shore Mine is a gold mine located in Kirkland Lake, Ontario. In July 1912, Harry Oakes staked claims L-2605-6 which were in the lake itself and had reverted for non-performance of work. On September 6, 1912, he registered the transfer of claim L-1557 that Melville McDougall had staked for Oakes previously. On September 23, 1911, Harry Oakes registered the transfer of claim T-16635 from George Minaker and named the property Lake Shore. In production from 1918 to 1965, the mine produced almost 8.5 million ounces of gold and represented over a third of the gold produced in the entire camp. The closure of the mine once known as the 'Jewel box of North America' in 1965 was the result of a number of factors including a declining ore reserve picture, unfruitful exploration, increased water inflow into the workings from other closed mines exceeding pump capacity and unstable workings at depth WIKIPEDIA
