Question: Did the Beaulieu Mine or the McIntyre Mines yield gold and copper?

The Beaulieu Mine was a post-World War II gold mining operation near Yellowknife, Northwest Territories.  It entered production in October 1947, but by the end of November only 7 troy ounces (220 g) of rough gold were recovered.  Additional gold was recovered during 1948, but altogether the mine recovered only 30 troy ounces (930 g) of fine gold.  The operation folded in chaos and bankruptcy. <SEP> The McIntyre mine is an abandoned underground gold mine in Schumacher, Ontario, Canada, which has earned a place in Canadian mining history as one of the nation's most important mines.  Its iconic headframe, located near downtown Timmins, has come to represent the entire Porcupine Gold Rush.  The McIntyre also yielded a considerable amount of copper over its life. <SEP> In World War II, the United States Navy needed a vessel that could consistently locate mines in [foreign or domestic?]  or littoral waters.  Littoral waters are found between the shore line and waters 60 meters deep.  The Accentor-class minesweeper (sometimes called the Accentor/Acme-class minesweeper) was developed for this task.  This class of minesweeper was named after the Accentor bird, Prunella modularis.  This bird is endemic to Europe, Asia, and North Africa which is the area that World War II occurred.  The bird is a drab brown and gray color and is in the same family as warblers and thrushes.  The Accentor-class mine sweeper was designed for the sweeping of mines in harbors, bays, and other littoral waters.  The Accentor-class minesweeper had a wooden hull for three reasons.  The first was that some of the mines that the Accentor-class minesweeper was trying to detect were detonated by a copper wire coming out of the top of the mine that is used to detect the magnetic field that is produced by the metal hulls of most ships; when the wire senses a magnetic field, it detonates the mine.  Minesweepers use wooden hulls because wood is a non-magnetic material, unlike steel, and would not set off this type of mine.  The second is that wooden hulls were lighter than metal hulls.  This caused them to float higher in the water, which made them displace less water and have a smaller pressure wave, so pressure mines would not be set off by the movement of the ship.  Lastly, due to the ship floating higher in the water, contact mines were not effective because they were often around 20 feet below the surface of the water, and the draft of this class of ship was between 8 feet 11 inches and 10 feet 8 inches.  Typically, the Accentor-class minesweepers were armed with a pair of .50 caliber machine guns for protection.  Rather than creating new minesweeping vessels, forty-five wooden-hulled fishing boats were converted into Accentor-class minesweepers.  This saved the Navy both time and money.  Since these converted fishing boats were not all the same, their specifications do vary a bit.  The converted fishing boats had a displacement from 165 to 270 tons of water.  They had speeds from 8.5 up to 14 knots and crews from as small as 15 up to 50. <SEP> Candente Copper Corp. is a Canadian mining company specialising in metals such as gold, silver, copper and zinc.  It is active in Mexico and Peru.  The company is headquartered in Vancouver, British Columbia.  Candente owns the Cañariaco Norte mine deposit, a large copper deposit in northern Peru estimated to contain 7.5 billion lbs of copper (Measured and Indicated at 0.45% Cu cutoff).  Candente estimates that the mine will yield 75,000 tonnes per day with a minimum life of nineteen years.  In September 2008, Candente announced plans to mine up to 1.43 million ounces of gold and 36.5 million ounces of silver from Cañariaco Norte.
