Copperfields Mine, originally known as Temagami Mine, is an abandoned copper and silver mine on Temagami Island in Lake Temagami, Ontario, Canada. The mine opened in 1955 and comprises both underground and surface workings within a sulfide ore body. Situated in Phyllis Township, the mine produced 34,000,000 dollars Canadian with 80 million pounds of copper, 230,028 ounces of silver and 13,271 ounces of gold. It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada. A mill was not initially needed because the ore was 28% copper. The mine closed in 1972 and is now flooded by water. Ruins of the Copperfields mill are present as foundations. It is possible to find mineral specimens in the spoil heaps of the old mine, such as chalcopyrite, pyrite, bornit
