Question: Are Copperfields Mine and Salmita Mine both located in the Northwest Territories?

<P0-S0> Lost McLeod Mine is a legend of a lost mine in the Northwest Territories of Canada. <P0-S1>  The story has been featured in many books and magazines. <P0-S2>  The events in the legend have led to geographic locations in the Northwest Territories being named Headless Valley and Headless Creek located in Nahanni National Park Reserve. <P0-S3>  A creek called Sheep Creek was renamed McCleod Creek in honour of the Mcleod Brothers. <P0-S4>  20 people have lost their lives searching for The Lost McLeod Mine. <SEP> <P1-S0>  The mine opened in 1955 and comprises both underground and surface workings within a sulfide ore body. <P1-S1>  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. <P1-S2> Copperfields Mine, originally known as Temagami Mine, is an abandoned copper and silver mine on Temagami Island in Lake Temagami, Ontario, Canada. <P1-S3>  It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada. <P1-S4>  A mill was not initially needed because the ore was 28% copper. <P1-S5>  The mine closed in 1972 and is now flooded by water. <P1-S6>  Ruins of the Copperfields mill are present as foundations. <P1-S7>  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. <P1-S8>  The Lake Temagami Access Road was created to ship ore from the mine site. <SEP> <P2-S0>  The deposit was first discovered in 1945 and underground exploration was carried out in 1951-1952. <P2-S1>  It was reactivated for exploration by Giant Yellowknife Mines Limited in 1975 and entered production in 1983. <P2-S2>  They used the old camp and milling plant of the abandoned Tundra Mine, located a few kilometres to the south. <P2-S3>  The mine produced 179,906 troy ounces (5596 kg) of gold from the milling of 238,177 tons of ore. <P2-S4> The Salmita Mine was a gold producer in the Northwest Territories, Canada during 1983 to 1987. <SEP> <P3-S0> The Colomac Mine was a privately owned and operated open pit gold mine located 220 km northwest of Yellowknife in the Northwest Territories in Canada . <P3-S1>  The Colomac mine operated between 1990–1992, and 1994–1997. <P3-S2>  It was operated by Neptune Resources Limited that had little success in making a profit during its operation. <P3-S3>  In 1994, the mine had reopened under Royal Oak Mines Inc. <P3-S4>  Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte. <P3-S5>  Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy. <P3-S6>  The Federal Government of Canada became owners of the mine, along with the related environmental issues. <P3-S7>  A major cleanup effort is under way to prevent the mine from polluting the environment, but this might be too late at this stage. <P3-S8>  This mine is now owned and controlled by the Indigenous and Northern Affairs department of the Federal government, while Public Works and Government services is the current contracting authority.
