May 25 2021 How Copper is Mined Copper is found alongside many other types of ore It can be found near gold silver zinc lead and other types of metal deposits When mixed in with other ores copper is not usually found in great abundance Until the development of the modern copper mining process it was typically a byproduct of mining for other metals.The Minto mine commenced Yukon mining operations in 2007 as an open pit mine In 2012 the company began underground development on the Minto South Deposits while continuing to mine additional open pits as the primary mining method Today the mining is entirely underground and we are currently producing in the Copper Keel ore body.The ultra high copper grades and underground mines mean that Kamoa Kakula will have a small surface footprint and use a fraction of the power water and consumables – and produce far less tailings – than comparable large low grade open pit porphyry copper mines currently in operation or under development elsewhere in the world.Discover More
