Mining Journal speaks with Paul Atherley, Chairman of Pensana Plc. Pensana, a rare earth element development group, is focused on its project Longonjo in Angola with plans for a downstream processing hub in the north of the UK. Longonjo plans to produce over 4,500 tons of ND peroxide annually, however, this project will become one of the very few small number of developments that enable the creation of an independent supply chain for magnet metal rare earths.
