Approximate location of the Syrymbet tin mine, owned by Tin One Mining

JSC Tin One Mining, formerly known as JSC Syrymbet, was founded in 1998 to carry out the development of the Syrymbet deposit, including mine and processing plant construction, in Kazakhstan. The Syrymbet licence area also incorporates the Sarybulak tantalum-niobium prospect. The company is a privately owned subsidiary of the Lancaster Group, a diversified holding company specialising in long term development opportunities. Samruk-Kazyna Invest, a subsidiary of the Kazakhstan government’s asset management division, has a minority share.

The Syrymbet Tin Project

The Syrymbet deposit is located in the Syrymbet ore field, north-west of the Kokchetav middle massif, within the Volodarskiy ore province. The venture is wholly owned by JSC Tin One Mining, which is permitted to carry out development and production within the license area until 2030. Commercial mineralisation at the deposit was first discovered by a drill-hole program in 1985, with further exploration in 1990 leading to the discovery of tin-bearing weathered crust with commercial potential. The ore field is associated with the intrusion of two late Devonian granite-porphyry stockworks (Syrymbet and Sarybulak).

The company claims that the deposit is currently the world’s largest undeveloped tin deposit, based on 2018 JORC reporting standards. JORC-compliant mineral resource estimation (MRE) reports from 2018 indicate in-situ resources comprising 181.2 Mt of ore containing 371 kt of tin.

A Definitive Feasibility Study (DFS) was completed in May 2020. From May 2022, Tin One Mining will be in a phase of construction of the plant, having constructed a railway siding and a potable water pipeline in 2018. Full construction of the plant is expected to be finished by 2025, and the commissioning and start-up of the plant is expected to begin soon after.
