by 1897, the calumet & hecla's red jacket shaft had reached a vertical depth of 4,900 feet, making it the deepest mine in the world. the neighboring tamarack mine became the world's deepest mine for some years; it was bought by calumet & hecla, and became part of the calumet & hecla system. the tamarack/c&h remained the world's deepest mine until about 1915, when its vertical depth of 5,500 feet was exceeded by the 5,824-foot depth of the morro velho gold mine in brazil.
