Longonjo ore reserve grade increases as project development progresses
London-listed Pensana has reported that the updated Joint Ore Reserve Committee- (Jorc-) compliant ore reserve grade for its Longonjo rare earth project, in Angola, has increased to 3.04% total rare earth oxide (TREO) containing 139 000 t of neodymium-praseodymium (NdPr) oxide for a mine life of over 20 years, making it one of the largest and highest-grade undeveloped magnet metal projects worldwide. The company says the plant will process 800 000 t/y with a feed grade for the first five years of 4.12% TREO with a very low strip ratio of 0.25 t of waste for each tonne of ore mined.
