Description Tertiary Minerals is in the age of exploration. The company, which explores for gold, tantalum, iron, and other minerals primarily in Scandinavia and Saudi Arabia, has refocused its efforts on fluorspar, an essential raw material for the fluorine chemicals business. In 2008 and 2010, it acquired the Storuman fluorspar project in Sweden and the Lassedalen fluorspar project in Norway. Some of its other projects include Ghurayyah (tantalum-niobium) in Saudi Arabia, Ahmavuoma (copper and gold) in Sweden, and Kaaresselkä (gold) in Finland. Tantalum is used in capacitors for consumer electronics. Its diamond interests were spun off as Sunrise Diamonds in 2005, and Tertiary still holds a major share in that company.
