were removed from the "C" and "D" ore zones. During Caland's mining operations, a pelletizing plant was constructed on site in 1965 at a cost of $17.5 million. Caland attempted an underground mine in 1957, however, water conditions, soft rock conditions and weak iron ore markets at the time made underground mining an unfavorable situation. In 1977, Caland moved into termination planning and developed a shutdown strategy based on involvement and participation. In November 1978, pit termination activities began. In 1979, the Pellet plant termination activities began along with the closure of the open pit. By April 1980 the Pellet plant shut down completely. The termination of Steep Rock Iron Mines and the Caland Ore Company was due to the cost of iron ore dropping and a surplus of iron ore pellets in the Great Lakes region.

The claims were secured in 1952 by Charleson Mining Company from the owners, J.A. Mathieu Ltd., C.E. Pattison, and Rawn Iron Mines Limited. By December 1960, Canadian Charleson Limited became a wholly owned subsidiary of Oglebay Norton Company. Gravel deposits as a source of iron ore was recognized after Steep Rock Iron Mines Limited opened up some pits for sand and gravel. The gravel on the property averaged approximately seventy feet thick and contained an estimated reserve of 50 million cubic yards of ore-baring gravel. In 1955, the company built a $2 million concentrator near what is now the Atikokan Municipal Airport. The concentrator contained a washing station and a screening station and was operated seasonally. The mining operation itself looked more like road construction than mining and used a Euclid Scrapers, which then transported it to the hopper to be dumped. After going through the concentrator the final result was a high grade product of 58% iron. During the seven years of operation the total amount of iron ore shipped from Canadian Charleson Limited was 672,895 tons.
