In crystaline limestone.

The dolomite deposit and plant of Dominion Magnesium, Limited, is situated on the east half of lot 20, concession V, Ross township.
The history of the steps leading to the production of magnesium metal from dolomite by the "Pidgeon process" in Canada, and descriptions of the process
have been published in several technical journals.2 In 1937, A.G.L. McNaughton, as director of the National Research Council of Canada, assigned L.M. Pidgeon to the problem of recovering magnesium metal from Canadian sources of raw materials. In March, 1941, Dominion Magnesium, Limited, was formed with funds supplied by Bobjo Mines, Limited, Moneta Porcupine Mines, Limited, and Ventures, Limited, through Robert J. Jowsey, Walter K. Segsworth, and Thayer Lindsley to further investigate and develop the process. Dominion Magnesium, Limited, built a pilot-plant, which successfully produced the metal by October, 1941. Construction of the main plant, which was financed by the Canadian Government, near Haley Station in Renfrew county, 14 miles north of Renfrew, was started in February, 1942. The first magnesium ingot was poured in August of that year, and full production attained in February, 1943. The plant capacity was 15 tons of magnesium ingot metal per day. Production in 1943 amounted to 7,153,974 pounds of magnesium. (ARV53)
