... such deposits as Olympic Dam and Ernest Henry in Australia, Kiruna-Aitik in Sweden, and Salobo in Brazil. Their considerable size, up to 2 billion tonnes, and polymetallic ore assemblages make them highly attractive targets for exploration. Common characteristics of this class include their Early to Middle...

... the same period in the Nautanen area, and a prospector was working a small gold mine (Fridhem). The Aitik deposit was discovered in 1932 by drilling on geophysical targets in an area where a rich ore boulder and a mineralized outcrop had been found. Further drilling was carried out in 1960 through 1965...

.... Deposits in Early Proterozoic granite-greenstone terranes, which include Norbotten, Skelleftea, and Bergslagen, dominate the metallogeny of Sweden. Norbotten is perhaps most famous for the Kiruna and Malmbergett Fe-P deposits, but the important Aitik porphyry Cu and Viscaria strata-bound Cu are also...
