Mineral exploration company High Power Exploration (HPX), which is headed up by chairperson and CEO Robert Friedland, has received consent from the Guinea government to acquire the 95% interest in the Nimba iron-ore deposit currently held by BHP, Newmont Goldcorp and Orano. The Nimba deposit is estimated to hold about one-billion tonnes of high-grade iron-ore containing very low levels of impurities, according to a review completed in 2015 by the US Geological Survey.
