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.
