Cornwall-based joint venture Imerys British Lithium Ltd has reported the resignation of two of its directors.
Companies House recorded that, on 12 November, Roderick Smith and Peter Long no longer held the posts.
Australian Mr Smith founded British Lithium Ltd, which processed lithium carbonate from Cornish granite on Imerys’ land.
Mr Smith’s son, Andrew, resigned as a director in June 2023, the same month that the company received clearance for a 20-80% JV with Imerys.
Roderick and Andrew Smith, Mr Long and Dr Martin Clarke remain directors of Lithium Assets Ltd based in the British Virgin Islands.
