It is the largest undeveloped gold deposit in Canada and one of the world's biggest copper-gold porphyry deposits. [5] [6] Though 2P reserves are significant (39 million ounces of gold, 214 million ounces of silver, 9.9 billion pounds of copper and 257 million pounds of molybdenum) they only represent about 65% of the mine's total resource of ...
Mining of the original Bethlehem Copper pits ceased in 1982. The Bethlehem concentrator continued to operate on ore from the Valley Copper deposit until June 1989. Production on the Valley Copper mine, now the largest mine and most noticeable feature, began in January 1983. [5] For fifty years the ore was dug using shovels and open pit methods ...
Taseko Mines: 1973–Present Reserves of 2.4 billion pounds of copper and 69 million pounds of molybdenum [1] Highland Valley Copper mine: Logan Lake: Teck Resources: 1962–Present [2] Mount Polley mine
As a result of these metal deposits, the Sudbury area is one of the world's major mining communities, and has fathered Vale Inco and Falconbridge Xstrata. The Basin is one of the world's largest suppliers of nickel and copper ores. Most of these mineral deposits are found on its outer rim. [citation needed]
This is an incomplete list of mines in British Columbia, Canada and includes operating and closed mines, as well as proposed mines at an advanced stage of development (e.g. mining permits applied for). Mines that are in operation are in bold. Past producers which are under re-exploitation, re-development and/or re-promotion are in italics. Also ...
The first truly industrial mining operation in what is now Canada was an iron mine at Forges du Saint-Maurice near Trois-Rivières in Quebec, which remained a going concern from 1738 to 1883. [1] Copper mining in Bruce Mines , Ontario—the first industrial-scale mine of a substance other than iron—followed in 1848. [ 2 ]
Porphyry copper deposits represent an important resource and the dominant source of copper that is mined today to satisfy global demand. [6] Via compilation of geological data, it has been found that the majority of porphyry deposits are Phanerozoic in age and were emplaced at depths of approximately 1 to 6 kilometres with vertical thicknesses on average of 2 kilometres.

Quesnel Lake is claimed to be the deepest fjord lake in the world, the third deepest lake in North America, and is the major tributary of the Fraser River. According to Mount Polley mine records filed with Environment Canada in 2013, there were “326 tonnes of nickel, over 400 tonnes of arsenic, 177 tonnes of lead and 18,400 tonnes of copper ...
