UK-listed East Star Resources Plc has announced that it has signed a preliminary agreement with China’s Xinhai Mining Services Limited to jointly develop the Verkh-Uba copper deposit in Kazakhstan.
Under the terms of the agreement, Xinhai Mining Services will lead the phased development of the project, which is estimated to require investments of around 65 million US dollars. The parties expect to finalize and sign a binding agreement within the next six months.
The Chinese partner will fully finance all stages of project development, including approximately 5000 meters of additional drilling to refine resource estimates and the construction and commissioning of a mining and processing facility with an annual capacity of 1 million tonnes. As investment volumes increase at each stage, Xinhai’s stake in the joint venture will rise from an initial 15 percent to as much as 70 percent.
East Star noted that the involvement of a strategic partner will reduce project risks and accelerate development timelines. The joint venture will also allow the company to redirect its efforts toward the discovery and evaluation of additional deposits, as East Star holds several other promising gold and copper licenses. These include the Talovskoye and Rulikhinskoye sites, with the latter estimated under JORC standards to contain 23 million tonnes of copper ore at an average grade of 2.4 percent.
In Kazakhstan, East Star focuses on the exploration of gold and base metals and has been conducting exploration activities for more than three years at three sites: Verkh-Uba, Talovskoye, and Snezhnoye. In February 2025, the company reported the identification of additional base metal resources, with JORC-compliant estimates for Verkh-Uba at that time placing resources at 20.3 million tonnes of ore containing 1.16 percent copper, 1.54 percent zinc, and 0.27 percent lead.
