(Adds detail) MOSCOW, Oct 31 (Reuters) - Gold miner Solidcore POLY=AIXN , formerly known as Polymetal, will buy a 55% interest in Kazakhstan's Syrymbet tin deposit from Lancaster Group subsidiary Berkut Mining for $82.5 million, it said on Thursday. The transaction will be financed from existing cash resources and is expected to complete in the fourth quarter of 2024, subject to regulatory approval, it added.

Lancaster Group belongs to a group of Kazakh businessmen. (Reporting by Anastasia Lyrchikova Writing by Marina Bobrova Editing by David Goodman)
