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.
Chris van Wijk, East Star Technical Director, comments
“We’re very happy with the soil sampling results on our Snowy licence. Our initial work using ASTER multispectral imagery identified several areas of potential hydrothermal alteration and guided the initial acquisition of this licence. The soil geochemistry completed has identified several areas with highly enriched pathfinder elements that correspond with anomalous areas highlighted by the multi-spectral imaging. The geochemical data is consistent with that seen proximal to other mineralised systems and worthy of further exploration.”
