Surface grab samples from the Southeast zone of the Koktasjal copper-gold porphyry project in northern Kazakhstan have returned encouraging results for Ursa Major International (URSA-C).
The new zone lies on the southeast flank, and outside the limit, of the previously delineated Koktasjal deposit. The structure, which consists of highly altered volcanic rocks, has a strike length exceeding 500 metres.
Some grab samples assayed as high as 3.28% copper and 0.48 gram gold per tonne.
Currently, two diamond drill rigs are testing the zone to a depth of 400 metres.
Meanwhile, other gold-in-soil anomalies have been identified on the 250-sq.-km Koktasjal licence area. Assays of greater than 1% copper have been found in grab samples from the Keregetas prospect, about 5 km southeast of the deposit, and next year will see the company prove up areas with gold-in-soil anomalies, surface mineralization and magnetic signatures similar to the deposit.
Previous exploration by the Soviets determined that the Koktasjal deposit contains 57 million tonnes grading 0.62% copper, 0.71 gram gold and 2.76 grams silver in the sulphide zone to a depth of 305 metres.
The deposit remains open to the southeast and at depth, and drilling in the Southeast zone is expected to increase the deposit’s size.
The company is also exploring three other mineral licences in central Kazakhstan.
