Kazchrome is preparing to bring the Dubersay section of the 40 Years of Kazakh SSR deposit in Kazakhstan’s Aktobe Region back into open-pit operation, with mining resumption planned for 2026–2027. The proposed operation is designed to handle approximately 3.2 million mt of total rock mass annually, including 260,000 mt of commercial chrome ore. The development would allow the company to access the deposit’s remaining open-pit reserves.
The Dubersay section has an estimated 260,000 mt of remaining chrome ore reserves, averaging 36.37% Cr₂O₃. Located approximately 12 km northeast of Khromtau, the site is close to Kazchrome’s Donskoy Ore Mining and Processing Plant. However, the planned resumption should not be interpreted as an operational restart: the available project information confirms the 2026–2027 target but does not report that open-pit mining has recommenced.
