McIntyre Mines Ltd.

• McIntyre Porcupine Mines Ltd.

McIntyre Mines Ltd., also formerly known as McIntyre Porcupine Mines Ltd., was a gold mining company which was based at a now-abandoned underground gold mine in Schumacher, ON. Its iconic headframe, located near downtown Timmins, ON, has come to represent the Porcupine Gold Rush. The McIntyre also yielded a considerable amount of copper over its life. The company's founder, Sandy McIntyre (1869-1943), had immigrated to Canada from Scotland around the turn of the century. He had changed his name from Alexander Oliphant, and in 1906 became a prospector, exploring Northern Ontario. McIntyre Porcupine Mines Ltd. was formed in 1911, adding land staked by Sandy McIntyre to nearby ground obtained by J. P. Bickell. Although the initial assays were lean, Bickell kept the company afloat through tough times. Later, as grades improved, he obtained additional ground. In 1919, Bickell left the investment business to become president and then chairman of McIntyre-Porcupine Mines. McIntyre sold his interest for $65,325, of which $60,000 was never collected. He did receive a pension for the use of his name, however. McIntyre Mine was incorporated in 1912. An investment in the mine was made by Henry Pellatt in 1915. By 1924, the mine included 626 acres, including the former Jupiter and Pearl Lake mines, besides the Plenaurum and Platt Veteran properties. The McIntyre (Number 11) headframe was completed in 1927. The shaft, along with new shops, processing, administrative, and change facilities were all located on the North shore of Pearl Lake. This led to the subsequent abandonment and demolition of the original mill located to the Southwest of the new facilities. The six-compartment shaft excavation underneath it was 4,250 feet (1,300 m) deep and 160,000 tons of rock, as well as 40,000 tons of water, were removed in the process. The project used 240,000 pounds of powder to blast the rock and 2,256,000 feet (688,000 m) of Douglas fir to timber the shaft. In its early days, the McIntyre mine problem-ridden. Mine manager Dick Ennis told how he ran to the bank with hot bullion bars to cover a payroll and how he disappeared underground to hide from creditors. In later years, the large profits from the mine enabled J. P. Bickell to loan the funds to Conn Smythe for the construction of Maple Leaf Gardens in Toronto, ON. During the 1930s, the company constructed the McIntyre Community Center in Schumacher. The facility includes both a hockey arena and a curling rink. It has since been taken over by the City of Timmins. The mine was owned and operated by McIntyre Porcupine Mines Ltd. until 1973, after which it was sold to Pamour Porcupine Mines. Overcoming the obstacles (thanks to Ennis) the McIntyre Mine went on to set a long list of firsts in mining and milling practices, as well as in health and safety. It was the first mine in Canada to have a metallurgist on the mill staff and employing a graduate engineer as mine superintendent. It was also the first in Canada to use rubber liners in milling and the first in the Porcupine camp to apply square-set and cut-and-fill stope mining. Gunitting was developed there; it adapted and introduced flotation to gold milling. The mine was also the first in Ontario to sink a shaft to below 4,000 feet. Ennis established mine safety procedures, including a daily report on safety conditions underground, a standard that is common today, and an attempt to tackle the serious health problem of silicosis. A McIntyre research group, which included the world-renowned Banting Institute of the University of Toronto, pursued the goal of finding a way of eliminating or reducing the solubility of silica particles by using small quantities of metallic aluminum dust in a two-stage dry that miners passed when they returned to surface. The non-profit McIntyre Research Foundation was formed to further the use of the treatment throughout the world mining industry. In 2015, the McIntyre Powder Project and Occupational Health Clinics for Ontario Workers began investigating the link between the McIntyre aluminum dust treatment and neurological disorders, including ALS and Parkinson's disease. The McIntyre Powder Project is a registry for miners who have health issues and who have been exposed to McIntyre Powder aluminum dust. Between 1912 and 1955 production was valued at $230 million and the company paid $62 million in dividends to shareholders. From 1912 to 1988, there were 37,529,691 tons milled, producing 10,745,361 ounces of gold, an overall grade of 0.29 ounces per ton. In the early 1960s, a substantial body of copper ore was noted Northwest of the old #6 shaft. By 1965, this was put into production and was an important addition to McIntyre Mine economics through the exhaustion of reserves in 1984. In the second half of the 20th century, McIntyre diversified and partnered with other mines in Canada and internationally (including Slocan and Canzac Mines in BC).
