Kiska Metals Corporation reports results from a drill program concluded on the Copper Joe property this fall. Copper Joe is a copper-gold-molybdenum porphyry prospect located in the Alaska Range 175 kilometers northwest of Anchorage.
The fall program totalled 885 metres in 2 holes, spaced at 740 metres and targeting coincident geological, geochemical and geophysical anomalies. The drilling did not return any significant assay results, but confirmed the presence of a strong porphyry-hydrothermal system. The drill program was funded by First Quantum Minerals Ltd ("First Quantum") under a Letter Agreement announced on August 27, 2014.
Kiska and First Quantum are currently undertaking an alteration and mineral chemistry study of rocks from surface and drill core to further evaluate the property and potentially identify vectors towards the core of the porphyry system.
Hole CJ14-01 targeted a zone of magnetite breccia and banded quartz-magnetite veins mapped at surface. This hole intersected two separate zones, approximately 80 to 100 metres wide (true width unknown) of heterolithic, magnetite flooded breccia cross-cutting a porphyritic quartz monzonite. The quartz monzonite is moderately to strongly sericite-pyrite altered, and contains local magnetite and k-feldspar alteration with trace chalcopyrite mineralization. The hole ended at 450 metres in rock-flour breccias with sericite-pyrite alteration and patchy magnetite alteration.
Drill hole CJ14-02 targeted a large conductivity anomaly coincident with anomalous copper-in-soil geochemistry. This hole intercepted moderately to strongly chlorite-epidote altered quartz monzonite breccia intruded by weakly altered biotite-feldspar porphyry. Numerous intervals of anomalous copper, molybdenum, zinc and silver occur throughout the hole; the best of which are hosted in strongly chlorite-epidote altered quartz monzonite and magnetite altered breccia containing fragments of biotite altered porphyry with disseminated chalcopyrite. This hole ended at 435 metres within a late-mineral, biotite-feldspar porphyry which contained sparse copper mineralization in narrow hematite-pyrite-chalcopyrite veins.
