[{"type":"text","content":"Taranis Completes Metallurgical Work at Thor Deposit on Gold and Sulphide Zones(via Thenewswire.ca)\n \n \nLakewood, Colorado / TNW-ACCESSWIRE / March 31, 2014 / Taranis (\"Taranis\") [TSX.V: TRO] has completed a preliminary metallurgical assessment on samples from the Thor Project located near Trout Lake, British Columbia. The metallurgical tests were conducted by ALS Metallurgy-Kamloops on two separate portions of the deposit including the main historic sulphide deposit containing silver, lead, zinc, gold and copper and the new Gold Zone known as SIF. ALS has also completed Acid-Base Assessment labwork of the ore that help characterize the ores and the associated waste products.\n\n \n \nThe Gold Zone\n\n \n \nThere is a considerable amount of outcropping gold mineralization in an area located immediately west of the known sulphide deposit that has not been outlined in the existing NI 43-10 Resource, and it is contained almost entirely within quartz-bearing zones. A 117.7 kg composite sample was collected from the SIF gold occurrence and served as the bulk metallurgical sample for the Gold Zone. The head grade was identical to that sampled during the Taranis panel sampling program in summer 2013:\n\n \n \nHead Grade for the Gold Zone Metallurgical Sample\n\n \n\nS(%)\n\n\n\n\nFe(%)\n\n\n\n\nAu(g/t)\n\n\n\n\n0.04\n\n\n\n\n1.07\n\n\n\n\n15.5\n\n\n \n \nThree separate processes to extract gold from the sample were tested: gravity concentration, flotation and cyanide leaching. Gravity recovery in the Gold Zone using a Knelson concentrator yielded 83% gold recovery to a concentrate grading 715g/tonne gold. Similarly, flotation recovered 97% gold from the feed to a concentrate grading 219 g/tonne gold. Cyanide leaching showed recoveries of 93% after 6 hours and 98% after 24 hours (ore ground to a nominal 67?m K80 for all tests). The positive results from flotation gravity and flotation process are encouraging as these processes are low cost and have less environmental impact when compared to cyanide leaching.\n\n \n \nThe Sulfide (Silver-Lead-Zinc) Zone\n\n \n \nRepresentative drill core from eighteen different drill holes were taken from the deposit at Thor and used for the metallurgical testing of the Sulphide Zone. The head grade for the metallurgical sample analyzed by ALS is shown in the following table:\n\n \n \nHead Grade for...
