Kiska Metals Starts Drilling at Copper Joe

Kiska Metals (TSXV:KSK) reported that optionee First Quantum Minerals (TSX:FM) has mobilized an exploration drill rig to commence a diamond drilling program at its Copper Joe project in Alaska.
As quoted in the press release:

The Copper Joe project hosts an extensive area of phyllic alteration, including local zones of potassic alteration, porphyry-style quartz-chalcopyrite veining, and hydrothermal breccias within Eocene and Miocene intrusive rocks. In 2015, Kiska and FM completed detailed alteration and vein mapping, alteration mineral chemistry mapping (white-mica hyperspectral analysis and chlorite chemistry), a 12 km² full-tensor MT geophysical survey, and applied Fathom Geophysic’s proprietary 3-dimensional porphyry footprint lithogeochemical modeling method. This work has defined two compelling porphyry targets, the Evening Star and Morning Star prospects. A plan map and cross-section can be found on Kiska’s website.
The Evening Star prospect is defined by a 2.5 km-diameter area of intense phyllic alteration with an outer margin of significant D-style quartz-pyrite veining and a 1 km-wide inner zone of significant banded quartz-molybdenite veining. Porphyry footprint lithogeochemical modeling, hyperspectral white-mica analysis, and chlorite chemistry analysis suggests that this inner zone represents the high-level centre of a porphyry system. The MT survey shows that this inner zone is coincident with a discrete, 1.4 km-wide low conductivity anomaly (<100 ohm-m) centred approximately 650 m from surface. This MT anomaly is draped by a 2.5 km-wide induced polarisation (IP) high chargeability anomaly defined by four pole-dipole IP lines. The core of this MT anomaly defines the drill target for the 2016 program, and will be tested with an 800 metre-long diamond drillhole. Kiska and FM drilled two holes in 2014 into what are now recognized as high-level breccia bodies and IP chargeability anomalies located marginal to the present target, and which contain no significant mineralization. Neither hole drilled in 2014 tested the above-mentioned conductivity low anomaly.
The newly-appreciated Morning Star prospect occurs 2.2 km to the southwest of Evening Star in a relatively low-lying area mostly covered by glacial till. The Morning Star is defined by narrow outcrop exposures in creek gulleys that contain chalcopyrite mineralization in EDM halos and B-style quartz veins over a 400 metre-wide area. Previous grab samples collected from this area returned significant copper and gold values. Morning Star has yet to be tested by geophysical surveys or drilling, and will be further investigated by geologists in 2016.
