Kiska Discovers New Porphyry Systems at Whistler Project, Alaska

Vancouver, BC - May 19, 2010: Kiska Metals Corporation ("Kiska" or the "Company") reports results of the first five drill holes of the spring 2010 exploration program at the Whistler copper-gold project, Alaska. Highlights include the discovery of a new porphyry center at Raintree East and strong indications of four others in the Raintree and Spur areas. To date, 11 holes of this 15-hole program have been completed, testing geophysical targets over a 50 km2 area with widely-spaced reconnaissance diamond drill holes. Each of these holes intersected porphyry-related alteration including a hole at the Raintree East that intersected porphyry mineralization that returned a 90 metre interval assaying 0.42 g/t gold and 0.1% copper. The presence of porphyry-style alteration and gold-copper mineralization in the reported holes indicates the potential for new porphyry gold-copper deposits that will be targeted in future drill programs. Results of the remaining 6 holes are pending.

"We are extremely pleased to have made additional porphyry discoveries at Whistler. This firmly supports our exploration concept that the Whistler Project is host to several individual gold-copper porphyry systems of which the Whistler resource is but one example," stated Jason Weber, President and CEO of Kiska Metals. "With the new Raintree East discovery, Kiska now has four porphyry centres (Raintree East, Raintree West, Rainmaker and Island Mountain) in addition to the Whistler resource. We are looking forward to our next drillholes and the followup to the 2009 discovery hole at Island Mountain which intersected 0.68 g/t gold over 382.9 metres, including the bottom 106.9 metres that averaged 1.22 g/t gold."

The current reconnaissance drilling program is focussing on the identification of new gold-copper porphyry targets on the 527 km2 Whistler Property to fulfill the terms of a back-in agreement with Kennecott Exploration Ltd. Under these terms, Kiska is to conduct a 341 line-kilometre Induced Polarization (IP) geophysical survey and test targets generated from this survey with a total of 20 drill holes. To date Kiska has completed 80% of the IP and 16 holes. The remaining IP and drilling is scheduled to be completed in June/July and once complete, will trigger a 90 day period in which Kennecott must elect to exercise or waive its back-in rights on the property.� �

With the discovery hole at Raintree East (WH10-008), Kiska has identified a new and distinct porphyry centre within the Raintree area. This hole tested a geophysical target located approximately 3 kilometres northeast of the multi-million ounce Whistler gold-copper resource, intersecting 0.42 g/t gold, 1.3 g/t silver and 0.1% copper over 90 metres beginning at a depth of 150 metres. Mineralization, similar to that seen at the Whistler resource, occurs in low density sheeted to stockwork quartz-chalcopyrite-pyrite veins hosted in andesitic volcanics. Two holes drilled in 2006 and 2008, located 500 metres to the south on the same geophysical feature, also intersected porphyry-style mineralization and returned encouraging results. These results, in the context of the new geophysical IP data, show the potential for a 700 metre footprint to this new and relatively untested porphyry target. A plan map showing drill hole locations and a cross-section of the WH10-008 intersection is available on Kiska’s website at:

Two additional holes in the Raintree area (WH10-004 and WH10-006) also indicate the presence of new porphyry systems. The Raintree North hole (WH10-004), located 1.25 km west-northwest from the Raintree East collar and 2 km northeast of the Whistler resource intersected strong peripheral-style alteration along its total length. The Red North hole (WH10-006), located 2 km southwest of Raintree North and 2.75 km east of the Whistler resource also intersected strong peripheral-style alteration including broad intervals of hydrothermal breccia and abundant gypsum veining. � Both of these features are proximal porphyry indicators, but more specifically show a close association to gold-copper mineralization at the Whistler resource and Raintree West zones. To date Kiska’s drilling within the 3 by 3 kilometre Raintree area has identified two centres of porphyry gold-copper mineralization and two areas of peripheral-style alteration related to as-yet-to-be identified porphyry centres.

Drilling also tested new targets in the 3 by 4 kilometre Spur area (WH10-005 and WH10-007) centred almost 5 kilometres northeast of the Whistler resource. The two holes, separated by approximately one kilometre, intersected strong peripheral-style alteration and carbonate-base metal veining, both of which suggest the presence of porphyry mineralization nearby. More detailed examination of the geophysics and use of metal zonation patterns will help to vector towards the causative porphyry systems in future drilling.

The 2010 program is managed by a joint committee comprised of technical management from both Kiska Metals and Kennecott Exploration Inc.� Work performed in this campaign will complete the program necessary to trigger a decision by Kennecott to exercise its one-time back-in right.� If exercised, Kennecott will refund Kiska 200% of exploration expenditures (currently estimated at a minimum $25 million payment) and advance Whistler to a positive prefeasibility study to earn a 51% project interest. Kennecott can then earn an additional 9% project interest by fully funding Whistler to a positive production decision.
