Temagami Island , formerly spelt as Timagami Island , is an island in Lake Temagami in Northeastern Ontario , Canada . It is the largest island within the lake, with Bear Island coming second. The island has many hiking trails that lead into the old-growth forest that is a mix of large white and red pine trees. Temagami Mine, later known as Copperfields Mine , was a copper mine that opened on Temagami Island in 1954. It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada. The mine closed in 1972.
5-559: 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
10-527: Is also home to Camp Wabikon , an overnight summer camp for youth ages 6–16. A bright white palladium mercury telluride mineral was discovered on Temagami Island in 1973 called temagamite , named after its discovery locality in Copperfields Mine , originally known as Temagami Mine. 46°57′37″N 80°02′08″W / 46.9604°N 80.0356°W / 46.9604; -80.0356 This Northern Ontario geographical article
15-562: The defined strike length of the gabbro. Copper is associated with chalcopyrite. Nickel is associated with millerite, gersdorffite , linnaeite and cobalt-nickel sulfarsenides. Copperfields Mine is the discovery site of a bright white mineral called temagamite . It was discovered in 1973. Temagami Island Temagami Island lies within n'Daki Menan, the homeland of the Teme-Augama Anishnabai , which covers almost 4,000 square miles (10,000 km ). Temagami Island
20-645: 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 , bornite , malachite , dolomite , hessite , merenskyite , millerite , palladium , quartz and others. The Lake Temagami Access Road
25-494: Was created to ship ore from the mine site. Copper-nickel mineralization at the mine is associated with semi-massive to disseminated pyrite at the lower contact between altered gabbro and rhyolite of the Temagami Greenstone Belt . The gabbro is steeply dipping , approximately 250 m thick and has a strike extent of at least 5 km. The intensity of mineralization varies greatly but is present over most of
