Tin One Mining has entered into a memorandum with the administration of the North Kazakhstan region to implement an investment project for the construction of a mining and processing plant at the Sarymbet tin deposit. The company plans to invest at least 150 billion tenge (approximately $315.5 million) into the development of the deposit, the construction of the processing plant, and associated infrastructure. This investment is subject to approval by the board of directors of Solidcore Resources, which controls the project.
The Sarymbet deposit is noted as the largest undeveloped tin deposit in Central Asia, with resources estimated at 492.4 thousand tonnes of tin at a grade of 0.40% and 91.4 thousand tonnes of copper at a grade of 0.07%, according to JORC standards. The deposit accounts for over 70% of the total tin reserves in Kazakhstan. Discovered in 1985, the site has significant potential for contributing to the region’s industrial growth.
Approximately 800 jobs are expected to be created as part of this project, with a focus on hiring local residents who possess the necessary education, qualifications, and professional competencies. Tin One Mining views this initiative as a long-term investment aimed at enhancing the industrial potential of the North Kazakhstan region and the country as a whole.
The administration has committed to supporting the project’s implementation by facilitating interactions with government bodies and overseeing the investment project throughout its various stages. In November 2024, Solidcore Resources acquired a controlling stake of 55% in the project for $82.5 million from Berkut Mining, which remains involved in the project while Solidcore takes operational control.
As of August 9, 2026, Tin One Mining is owned by Tin One Holding, which is in turn owned by Solidcore Eurasia LTD and Berkut Mining, both of which are part of the larger Solidcore Resources PLC structure. This investment marks a significant step in the development of Kazakhstan’s mining sector, particularly in the tin industry, which is poised for growth given the increasing global demand for tin and its applications in various industries.
