St. Joe Minerals Corp was founded in 1902 in St. Joe, Idaho.
The company was originally involved in the mining of lead and zinc.
The St. Joe Mine was a significant operation for the company, with production peaking in the 1950s.
It was one of the largest lead and zinc mines in the United States at the time.
The mine was eventually closed in 1985 due to declining ore reserves and increasing production costs.
The site has since been reclaimed and is now a wildlife habitat.
