Kazakhstani geological exploration company Aurora Minerals has disclosed that illegal artisanal miners are actively extracting gold from its Altyn project in northern Pribalkhashe — a problem the company’s chief geologist Ulan Nurkhannuly colourfully framed as “pirates” operating within their licence area, in a presentation at the Geoscience and Exploration Central Asia forum in Astana.
Nurkhannuly told the forum’s session on junior company challenges that the Altyn project sits on the boundary of a gold ore field, making it geologically prospective for new discoveries. The project currently covers 80 square kilometres, though Aurora Minerals has identified scope to expand the licence area to between 355 and 360 square kilometres, with the application process already underway. The company has named its priority exploration targets within the project El Dorado, Captain Morgan and Port Royal — a nod, Nurkhannuly explained, to the pirate theme necessitated by the uninvited activity on site. Illegal miners are reportedly extracting both hard rock and alluvial gold at three separate locations within the licence area, effectively running their own informal junior mining operation. They have even installed a water extraction borehole — infrastructure that may prove useful to Aurora given existing water supply challenges in the region.
A sample taken by Aurora’s team at one of the illegal mining sites returned an exceptional grade of 500 grams of gold per tonne. Historic data generated in the 1980s suggests the broader project area may contain approximately 360,000 ounces, or over 11 tonnes of gold. Further study has identified additional zones warranting exploration.
Beyond Altyn, Aurora Minerals is pursuing what could prove to be a significantly larger opportunity at its Teniz project, located on the tripoint border of Akmola, Kostanai and Karaganda regions. The company believes the area represents an extension of the Chu-Sarysu sedimentary basin — a geological setting comparable to the giant Zhezkazgan copper deposit. Surface copper showings are sparse, consistent with that analogy. The United States Geological Survey has forecast that the Teniz basin could host up to nine copper deposits with combined resources of as much as nine million tonnes of copper. On the basis of historical data and the US geological forecast, Aurora has identified priority targets across the region and secured licences covering up to 2,000 square kilometres, with the potential to add three further licences and expand the surveyed area to 4,500 square kilometres. Licensing negotiations with state authorities took considerable time due to the presence of a Russian rocket impact zone within the Teniz depression.
