(\"\n \n Defense Metals\n \n \" or the \"\n \n Company\n \n \") (TSX-V:DEFN) (OTCQB:DFMTF) (FSE:35D) is extremely pleased to report the most recent results of the extensive comminution and beneficiation test work that has been conducted by SGS Canada Inc. in\n \n Lakefield, Ontario\n \n (\"\n \n SGS\n \n \") on variability samples from the Wicheeda Rare Earth deposit.\n \n \n \n \n Craig Taylor\n \n , CEO of Defense Metals, stated:\n \n \n \"Our recent results shows that the Wicheeda feedstock can be crushed, ground and floated to produce a rare earth flotation product with similar or better recoveries and grades to the top producers globally. Our project has many favorable conditions for success: mineralogy, metallurgy, infrastructure, and community collaboration further supporting a path to production.\"\n \n \n \n \n Beneficiation Results\n \n \n \n \n A total of 90 open-circuit flotation tests, using 1 or 2 kg of feed, were conducted on seventeen individual variability samples, various composites and blends.  Considering all open-circuit flotation tests, at a feed grade of 3% TREO (Total Rare Earth Oxide), the best fit line indicated 80% recovery to a 45% TREO concentrate. Closed circuit operations, as practised in flotation plants, can be expected to deliver higher recovery and grade.\n \n \n In addition to the smaller-scale tests, 29 bulk flotation tests using 10 or 12 kg charges were completed to both further optimize parameters and generate 16 kg of 46% TREO content with a recovery of 78% for use as feed for hydrometallurgical tests.\n \n \n Very favourable results were obtained in a locked cycle test on a deposit composite giving a recovery rate of 85% of the rare earths at a concentrate grade of 50.7% TREO.\n \n \n \n The beneficiation te...
