An underground Cu mine, the Huron Mine was organized in 1853 and was the first large investment of eastern capital in the Copper Country. The mine consisted of ten shafts, all working the rich Isle Royale lode. In the first ten feet of one of the shafts, a three ton mass of copper was removed which excited workers, investors, and the public. In 1857 a stamp mill was built to process the copper ore. Work continued until 1870, when the mine closed due to erratic mineralization of the lode at depth. Tributers continued work at the deepest levels (21st) of the mine until 1893, when the Huron Mine closed for good. In the forty years the mine operated, 35,766,000 pounds of copper was produced. Today, one can still find bits of copper, silver, and rare bornite on what's left of the tailing piles.
