 communities throughout this period.

The mine was initially developed as a collaboration between the American Metal Company (later Amax) and Inco (International Nickel Company) and consequently was also known as the Little River Joint Venture.

The mine was named after Mr. Heathcliff Steele, the Vice-President of Exploration of the American Metal Company. It seems that Mr. Steele had little directly to do with the mine, but the parent company probably bestowed the name as an honour on his retirement from the company.

. This was the first discovery in Canada of an ore body by means of an airborne electromagnetic survey (AEM).

American Metals had financed Mr. Boylen's exploration, and as a result of a 1953 agreement with Inco, acquired a 75% ownership of the new mine. Initial exploratory drilling estimated the reserves as including 4,200,000 tons (2.9% Lead, 7.1% Zinc, 1.1% Copper, 3.20 ounces/ton Silver, and 0.02 ounces/ton Gold) and 3,000,000 tons (1.2% Lead, 3.5% Zinc, 1.3% Copper, 1.90 ounces/ton Silver, and 0.02 ounces/ton Gold).

By 1957 a mine and milling operation were established to extract copper, lead and zinc from the ore; it was served by a 30 kilometre railway line from the CN Rail

 main line at Bartibog Station. Due to low metal prices and metallurgical issues, the mining operation was suspended in April 1958. Mining resumed in June 1962. In 1969 the mine started an ambitious expansion, and by 1979 was producing over 185,000 tonnes of mineral concentrates per year.

As the ore body was gradually depleted operations were increasingly dependent on strong metal prices. In 1979 Noranda purchased American Metals 75% share in the operation. Metal prices declined, forcing the mine to suspend operations in April 1983. In 1986 Noranda purchased all of the remaining interest in the mine. The mine reopened in 1989, closed in 1991, reopened in 1992. Mining was again suspended in July 1993, resuming in November 1994. As of 1994 reserves stood at 3.6 Mt (7.1% zinc, 2.0% lead, 0.9% copper and 73 g/t silver). The underground mine was finally closed and allowed to flood in 1999.
