Kiska Reports Copper and Gold Recoveries From Initial Metallurgical Studies at Island Mountain Prospect, Whistler Project, Alaska

VANCOUVER, Oct. 21 /PRNewswire/ - Kiska Metals Corporation ("Kiska" or the "Company") is pleased to report the results of initial metallurgical studies carried out on copper-gold mineralization from its Island Mountain Prospect, Whistler Project, Alaska. Tests on two composite samples utilizing open circuit flotation followed by cyanide leaching of flotation tailings returned average copper concentrates grading 23% copper with recoveries averaging 67% for copper and 82% for gold.

"Given the early stage of the testing, we are very pleased with the initial metallurgical results at Island Mountain. Further metallurgical work will investigate maximizing gold recoveries by gravity separation and locked cycle flotation processing, as well as other methods of process optimization. These additional techniques seeking better recoveries represent the standard procedure that follows initial tests and are expected to improve overall metallurgical performance and metal recoveries." stated Jason Weber, president and CEO of Kiska Metals. "This test work also demonstrates that mineralization at Island Mountain is amenable to the same conventional metallurgical processing methods anticipated for gold and copper recovery at the Whistler Deposit. As such, it becomes more likely that mineralized material from both the Island Mountain and Whistler deposits can be treated at a single centrally located processing facility. It is a significant realization that the Island Mountain mineralization can potentially be viewed as a growing part of a district resource base when combined with the Whistler Deposit resource. Given that view, there is strong justification for proceeding with an aggressive exploration effort at Island Mountain, in addition to the exploration program for the Whistler Orbit, to define new gold-copper resources on the project."

Two composite samples were collected from the Island Mountain discovery hole, IM09-001, representing the upper intercept (150 metres 0.72g/t gold, 0.16% copper) and copper-poor lower intercept (107 metres of 1.22g/t gold and 0.05% copper). Testing of both zones determined that selective flotation of a copper plus gold concentrate and subsequent cyanide leaching of the combined cleaner and rougher tailings produced a saleable copper concentrate with excellent overall gold recoveries. This testing was undertaken to determine the metallurgical characteristics of the two distinctly different styles of mineralization noted at Island Mountain and to compare these characteristics with those anticipated at the Whistler Deposit, 23 kilometres to the northeast.

Open circuit flotation followed by cyanide leaching of the flotation tailings from the lower intercept recovered 70.6% of the copper and 89.6% of the gold. The tests produced a copper concentrate grading 23.3%. The cyanide leach of the flotation tailings was conducted over a 48 hour period with an industry standard cyanide consumption rate of 0.38 kg/t.

Open circuit flotation tests followed by cyanide leaching of the flotation tailings from the upper intercept, recovered 63.4% of copper and 75.1% of gold. The tests produced a copper concentrate grading 22.5%. The cyanide leach of the flotation tailings was also carried out over a 48 hour period with an industry standard cyanide consumption rate of 0.4 kg/t.

Metallurgical testing was carried out by G&T Metallurgical Labs in Kamloops B.C. under the supervision of Robert J. Tucker P.Eng. who also provided the interpretation of results.
