    Tin One Mining to Launch $227M Tin Production Project at Syrymbet Deposit in Kazakhstan

    A new mining and processing plant will be built at the Syrymbet deposit in Kazakhstan’s Ayyrtau district, where Tin One Mining — part of Solidcore Resources — plans to produce up to 11,000 tonnes of tin annually. The investment project, valued at $227 million, was announced by regional deputy governor Kanat Duzelbayev during the North Kazakhstan–China Investment Business Forum.

    Tin One Mining intends to commission the plant in 2028, creating around 600 jobs. The Syrymbet deposit, discovered by Soviet geologists in 1985, contains a complex mix of metals including tin, tungsten, tantalum, niobium, molybdenum, beryllium, bismuth, copper, and fluorite. Early studies identified tin-rich weathering crusts that formed a new industrial category of tin-bearing ore for the region.

    The site’s resources were estimated under JORC standards in 2018 at 206,000 tonnes of tin and over 70,000 tonnes of copper. Following exploration in 2025, tin reserves were upgraded to 286,000 tonnes, while copper reserves were revised downward to 55,000 tonnes. Solidcore Resources acquired a 55% stake in the project operator for $82.5 million at the end of 2024.

    Polymetal is exploring the reserves of the Syrymbet tin deposit together with Tin One Mining, which holds the subsoil license for this site. The publication on inbusiness.kz reported that mining companies are strengthening cooperation.

    Tin One Mining and Polymetal specialists need to select options on how to optimize the existing technological scheme for processing the deposit’s tin ores. According to representatives of the gold mining company in response to a media request, the parties have been cooperating in this direction for more than one year.

    Polymetal may potentially acquire a share in the project in the future. Incidentally, it was precisely the issue of studying the properties of ore, the lack of suitable competencies and solutions, that at one time slowed down the development of Syrymbet.

    Proposals to develop the site first came in the late 1990s, and tin mining began only in 2021. The mining and metallurgical plant at Kazakhstan’s largest tin deposit was planned to be launched by 2025, according to Tin One Mining’s management.

    During a recent conference call with investors, held, the head of Polymetal, Vitaly Nesis, said that in the future the company may be interested in Kazakh deposits of copper, tin, lead, and zinc.
