East Star publishes copper porphyry exploration update
East Star Resources Plc, which is exploring for copper in Kazakhstan, has released an update on its copper porphyry exploration strategy at the Snowy licence, on the paleozoic Balkash-Ili volcanic arc, which was initially funded by a US$500 000 BHP Xplor grant.

East Star Resources Plc, which is exploring for copper in Kazakhstan, has released an update on its copper porphyry exploration strategy at the Snowy licence, on the paleozoic Balkash-Ili volcanic arc, which was initially funded by a US$500 000 BHP Xplor grant.
Highlights
Soil sampling has identified a very large gold (Au) in soil anomaly (5 km by 1 km), coincident with the alteration signature from the multispectral imagery and directly along strike from an artisanal gold mine.
A second large anomaly (2km by 2km) with porphyry potential, has been identified through strong molybdenum (Mo) and bismuth (Bi) pathfinder elements, with results indicating >10 times Mo and >100 times Bi above anomalous thresholds.
Based on the data, management consider Snowy warrants further exploration for potential epithermal gold and copper porphyry systems.
Next steps
Field verification of the targets and geological mapping over the areas identified by the soil geochemistry is a necessary next step. In the Central Target area, field mapping will aim to identify veining consistent with a porphyry system at explorable depth, whilst mapping of the East Target will look for veins and textures supportive of epithermal mineralisation. If the field mapping supports the target styles of mineralisation, a likely next step would be geophysics in the form of an Induced Polarity (IP) survey designed to directly target disseminated sulfide mineralisation.
