Elsewhere, Pensana, the London-listed rare earths developer, saw its shares spike 9% today on news it had secured grant funding of £316,643 (with Polestar, Route2 and the Universities of Leeds and Hull) by Innovate UK as part of the £15 million CLIMATES program.
The partnership will develop a low-carbon, sustainable supply chain for rare earth magnets. It is backed by the UK Government and is expected to "review and measure impacts and identify opportunities to further reduce carbon in the rare earth products vital for the energy transition".
Nusrat Ghani, Minister of State at the Department for Business and Trade, said that the government was "laser-focused" on securing robust supply chains "for the growing, green industries that will deliver jobs and prosperity across the UK in the decades to come".
