The Leitch is the highest grade long running high tonnage mine that operated in Canada at one million ounces of one ounce gold per ton. It closed in 1968 having operated continuously for 38 years. The Sand River operated at 0.75 ounces per ton for its life. (I visited briefly Beardmore during the operation of the mine in 1963.) The Little Long Lac was still running then too. It close in 1972. It produced 605,0000 ounces from 1.8 million tons of ore, a respectable grade. It had produced continuously since 1934. There were 1.2 million tons of ore left in the mine when it closed. It was not mined out. Lac Minerals, then Little Long Lac, had wanted to reopen the mine in 1980 but hit Hemlo at the time, so got segued into that massive capital development. Some of the mines of the Geraldton-Beardmore area had long life. Many mines that started in the 30's only lasted a few years. (The Leitch matched the grade of the Discovery Mine of the NWT in grade and tonnage.) The Leitch's secret was it used resuing to maintain its grade. The values were taken from an ore-cut that was 18 inches to 3 feet wide. The stope was wider for access purposes but they did not take it all as ore to the surface. A few mines in that area were quite high grade. The Northern Empire ran at 0.38. The Dik Dik ran at 0.40, the Magnet ran at 0.40 and the Hardrock Mine ran at 0.50 OPT. The Mcleod-Mosher was low grade at 0.15 but it put through massive tonnage. Some zones were 150 feet wide. (F-Zone) ingentaconnect.com I used to ski with Rheinhart Mosher who was the son of the prospector who staked the McLeod Mosher mine. He lived in Kirkland Lake. At the time of discovery you had to get into that area by rail. The road did not come until a few years later.
