(\"Namibia Rare\n Earths\" or the \"Company\") (TSX: NRE) (OTCQX: NMREF) is pleased to\n report that it has received a preliminary metallurgical report from\n Mintek confirming that a xenotime concentrate can be produced from the\n fine grained mineralization at the Lofdal Rare Earth Project in\n northwestern Namibia, and that thorium can be removed from concentrates\n on site. A concentrate grade of 8.39% TREO with 96.1% heavy rare earth\n enrichment was produced from a representative sample of the high grade\n mineralization with a head grade of 1.37% TREO and achieved an overall\n recovery of 64.7%. Concentrates were also produced from sorted product\n and from fines (Table 1). (Please click here for Table 1) The report provides a number of recommendations to optimize grades and\n recoveries.\n\n\nSample preparation of metallurgical samples is provided by Mintek (South\n Africa) and final analytical work is provided by Activation\n Laboratories Ltd. (Ancaster, Ontario) employing ICP-MS techniques\n suitable for rare earth element analyses and following strict internal\n QAQC procedures inserting standards and duplicates.\n\n\nDon Burton, President of Namibia Rare Earths stated,\n\n\n\"These preliminary results from Mintek indicate that we will be able to\n produce valuable concentrates from Lofdal that are extremely enriched\n in heavy rare earths, most notably in dysprosium, yttrium, terbium and\n europium. We have also determined that the removal of thorium can be\n achieved at site using conventional leaching techniques. The work by\n Tomra Sorting Solutions confirms the potential to significantly reduce\n the volume of run-of-mine material that must go to the mill for\n grinding, thereby increasing the grade of the mi...
