Question: What type of mines are Dome Mine and Camlaren Mine in Canada?

<P0-S0>  Littoral waters are found between the shore line and waters 60 meters deep. <P0-S1>  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. <P0-S2>  Minesweepers use wooden hulls because wood is a non-magnetic material, unlike steel, and would not set off this type of mine. <P0-S3>  The Accentor-class mine sweeper was designed for the sweeping of mines in harbors, bays, and other littoral waters. <P0-S4>  The bird is a drab brown and gray color and is in the same family as warblers and thrushes. <P0-S5>  The Accentor-class minesweeper (sometimes called the Accentor/Acme-class minesweeper) was developed for this task. <P0-S6>  This bird is endemic to Europe, Asia, and North Africa which is the area that World War II occurred. <P0-S7>  Rather than creating new minesweeping vessels, forty-five wooden-hulled fishing boats were converted into Accentor-class minesweepers. <P0-S8>  They had speeds from 8.5 up to 14 knots and crews from as small as 15 up to 50. <P0-S9>  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. <P0-S10>  or littoral waters. <P0-S11> In World War II, the United States Navy needed a vessel that could consistently locate mines in [foreign or domestic?] <P0-S12>  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. <P0-S13>  Typically, the Accentor-class minesweepers were armed with a pair of .50 caliber machine guns for protection. <P0-S14>  The Accentor-class minesweeper had a wooden hull for three reasons. <SEP> <P1-S0> The Camlaren Mine was a small gold mine 80 km north-east of Yellowknife, Northwest Territories, Canada at Gordon Lake. <P1-S1>  It consists of a property totaling about 981 hectares. <P1-S2>  The two claims that make up the property were staked in 1936 by prospectors Don Cameron and the Mclaren brothers and developed with two shafts during 1937-1938. <P1-S3>  The name "Camlaren" is a portmanteau of Cameron and McLaren. <P1-S4>  Conditions attributed to World War II halted development at Camlaren in 1939. <SEP> <P2-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 . <P2-S1>  The Colomac mine operated between 1990–1992, and 1994–1997. <P2-S2>  It was operated by Neptune Resources Limited that had little success in making a profit during its operation. <P2-S3>  In 1994, the mine had reopened under Royal Oak Mines Inc. <P2-S4>  Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte. <P2-S5>  Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy. <P2-S6>  The Federal Government of Canada became owners of the mine, along with the related environmental issues. <P2-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. <P2-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. <SEP> <P3-S0> Dome Mine is situated in the City of Timmins, Ontario, Canada; and was developed during the Porcupine Gold Rush.
