Angolan diamond firm to explore niobium deposits – report

23 august 2017
Angolan state-owned diamond company Endiama has partnered with the Blue Mining company to explore niobium deposits in Huí­la province, southern Angola.
Macauhub reports that geology and mines minister, Francisco Queiroz, approved the mining investment contract and the rights granted for the Quilengues concession to the two companies in the form of a new company to be set up to explore the niobium deposits.
Niobium is one of the world’s rarest minerals. It is used to manufacture turbines, spacecraft, aircraft, missiles, electronics and power plants, but also to produce steel alloys and superconductors.
Macauhub also reports that the initial investment planned for the mining project was $20 million.
Brazil had the world’s largest reserves of niobium estimated at 842 million tonnes.
