Is the Outpost Island Mine and Jolly Jack's Lost Mine mines?
Outpost Island Mine The Outpost Island Mine was a gold and tungsten producer 94 kilometres southeast of Yellowknife, Northwest Territories on an island of Great Slave Lake. Gold was discovered here in 1935 by prospectors, and some development was undertaken in 1936-1938. Tungsten ores became valuable during World War II, so the owners (Slave Lake Gold Mines Limited) investigated the tungsten possibilities of the mine. It produced small amounts of gold, copper, and tungsten during 1941-1942, and then again in 1951-1952 during the Korean War. It was a small deposit and was not considered economic because of unpredictable tungsten market prices in the 1950s.
Magnetic Island (Alaska) Magnetic Island is a small island on the north side of Tuxnedi Bay, an inlet on the lower west side of Cook Inlet in south-central Alaska. The island is surrounded by mudflats that are under water during high tides. The island got its name from the presence of magnetism (believed due to magnetite) identified during a geological survey in 1951. Its shape and geology are heavily influenced by Mount Redoubt and Mount Iliamna, two active volcanoes located less than 20 mi away. The island is most notable for its archaeological significance, which includes a prehistoric human habitation site which has been dated to c. 1800-1400 BCE. The sites consists of a series of depressions, which when excavated in 2012, yielded several layers of cultural materials, included fire-cracked stones and hearths, and stone tools stylistically associated with the Arctic Small Tool tradition. The site was probably abandoned due to volcanic activity.
