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, and re-opened in 1992. Mining was again suspended in July
321:. 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 (182,000 long tons; 204,000 short tons) of mineral concentrates per year.

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 tonnes (4,100,000 long tons; 4,600,000 short tons) (2.9% Lead, 7.1% Zinc, 1.1%

The mine was named after Mr. Heath 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.
