History
2> McIntyre Porcupine 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. Between 1912 and 1955 production was valued at $230 million and the company paid $62 million in dividends to shareholders. McIntyre sold his interest for $65,325, of which $60,000 was never collected. He was awarded a life pension for the use of his name although his real name was Alexander Oliphant.[citation needed] The McIntyre (Number 11) headframe was completed in 1927. 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 was a nightmare of problems. It was remarked "it is doubtful if any major mining corporation anywhere was ever established on a shakier foundation." 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. 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. They were the first in Ontario to sink a shaft to below 4,000 feet. Always the innovator, Ennis took the lead in mine safety in establishing procedures which gave a daily report on safety conditions underground, a standard that is common today. Under Ennis's leadership, McIntyre became internationally famous when it tackled the serious health problem of silicosis. European researchers had discovered that the scarring of lungs caused by silicosis was the result of a complex chemical reaction between silica particles and lung tissue. 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. 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. [edit]
