The Koskuduk caldera lies within the Balkhash volcanic belt, which is part of the massive, globally significant Central Asian Orogenic Belt that controls most of Kazakhstan’s porphyry-copper deposits. The deposits host a combined resource currently estimated at more than 25 million tonnes of copper.
Hydrothermal alteration and prominent litho-caps typical of porphyry-type mineralisation are evident at several of the prospects Sarytogan has identified in the Koskuduk caldera.
Litho-caps represent common exploration objectives for porphyry and epithermal deposits because of their size and well-recognised geochemistry and can host high sulfidation epithermal gold and copper mineralisation.
Sarytogan will move its field team to the project next month to undertake soil sampling and is planning an aeromagnetic survey over the Kopa project to help identify meaningful structures to assist exploration.
The company will also soon kick off further soil sampling and drilling at its Baynazar copper project, about 530km north of Kopa.
