About this update from Valore Metals Corp.
[{"type":"text","content":"\n\n\nVANCOUVER, Sept. 11, 2013 /CNW/ - Kivalliq Energy Corporation (\"Kivalliq\", TSX-V: KIV) today provided an update on ongoing metallurgical and beneficiation\n studies for Kivalliq's 340,268 acre Angilak Property in Nunavut\n Territory. This update summarizes preliminary results from work\n performed on the Lac 50 Trend deposits, including: metallurgical\n testing of the J4 and Lac 50 zones as well as characterization studies\n related to optimal ore sorting methods.\n\n\n\"Results from ongoing metallurgical work at Lac 50 are encouraging,\"\n stated Chuck Edwards, Director of Metallurgy at AMEC.  \"Optimizing\n sulphide recovery, plus improvements to alkaline leach kinetics using\n oxygen as oxidant, could have a positive impact on reducing costs\n associated with potential treatment options.\"\n\n\nKey Point Summary: \n\n\nJ4 Zone flotation achieved an optimum sulphide recovery of 99.2% in\n alkaline solution at a grind size of 100% passing 140 mesh (106 µm).\n\n\nPositive alkaline leach results on J4 Zone indicate rapid uranium\n extraction: 92.3% in 12 hours, 95.2% in 24 hours and 96.7% in 48 hours.\n\n\nUsing improved alkaline leach parameters defined by the J4 Zone testing,\n retesting of the 2012 Lac 50 composite upgraded the leach extraction of\n uranium to: 91.7% in 12 hours, 95.1% in 24 hours and 96.4% in 48 hours.\n (previous results released February 28, 2013)\n\n\nJ4 Zone sulphide flotation and alkaline leach results are consistent\n with other Lac 50 deposits.\n\n\nPreliminary ore sort characterization of rock specimens from Lac 50\n deposits indicates that radiometric sorting will be very effective.\n Radiometric characterization analysis demonstrates a 56% reduction in\n mass with 98% U3O8 recovery.\n\n\nMetallurgical Results Demonstrate High Uranium Recoveries and Rapid\n Leach Kinetics\n\n\nIn 2012, the Saskatchewan Research Council (\"SRC\") commenced a\n metallurgical testing program on core from Kivalliq's Lac 50 Trend. The\n program objectives were to maximize uranium extraction through the\n removal of sulphides using flotation and optimizing the alkaline\n leaching processes. Results from the 2012 metallurgical program were\n very encouraging with high U3O8 recovery rates and the production of a low impurity final yellowcake\n product.
