What did Salmita Mine and Outpost Island Mine both mine for
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.
Antelomita Hydroelectric Power Station The Antelomita Hydroelectric Power Station is located in Antelomita of the Analamanga Region, Madagascar. The power station comprises two parts, Antelomita I and II. Both are adjacent to one another on separate water falls along the Ikopa River. Each water fall is dammed and water is diverted to the power station; each of which contains three 1.4 MW generators. The first two were commissioned in 1930, the second two in 1952 and the final two in 1953. Both stages have an installed capacity of 8.4 MW . They were built by a French firm but are now owned and operated by Jirama. The Tsiazompaniry and Mantasoa Dams upstream regulate water to the power station.
