Question: Are Copperfields Mine and Salmita Mine both located in the Northwest Territories?
Context: 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 .  The Colomac mine operated between 1990–1992, and 1994–1997.  It was operated by Neptune Resources Limited that had little success in making a profit during its operation.  In 1994, the mine had reopened under Royal Oak Mines Inc.  Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte.  Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy.  The Federal Government of Canada became owners of the mine, along with the related environmental issues.  A major cleanup effort is under way to prevent the mine from polluting the environment, but this might be too late at this stage.  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. 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, bornite, malachite, dolomite, hessite, merenskyite, millerite, palladium, quartz and others.  The Lake Temagami Access Road was created to ship ore from the mine site. The 2012 NWT/Yukon Scotties Tournament of Hearts, the women's provincial curling championship for the Yukon and Northwest Territories, were originally scheduled for January 26 to 29 at the Yellowknife Curling Club in Yellowknife, Northwest Territories.

The Mactung Project is a planned open pit tungsten mine located in the Selwyn Mountains of eastern Yukon, Canada, on its border with the Northwest Territories.  Mactung represents one of the largest tungsten resources in Canada having estimated reserves of 33 million tonnes of ore grading 0.88% WO.  The Mactung Project completed the Yukon Environmental and Socio-economic Assessment process in July 2014, and the Yukon government approved construction of the mine (pending mining and water licence applications, and subject to a number of conditions) in September 2014.  North American Tungsten Corporation estimated the capital cost of the mine's construction to be approximately CA$400 million.  In November 2015, the Government of the Northwest Territories purchased the mineral deposit.
