Cornish Lithium Secures £35m of Equity Funding to Advance Projects to Next Stage of Development

· £35m of equity funding secured with up to £31m from the National Wealth Fund (NWF) and £4m from TechMet. · Funding will progress the Trelavour Lithium Project towards a construction decision and the Cross Lanes Geothermal Lithium Project to commercial drilling, advancing the business to the next stage of development. · New crowdfunding campaign to launch on the Crowdcube platform to allow existing and new investors to participate.

Cornish Lithium, the innovative mineral development company pioneering the sustainable extraction of lithium in the UK, is pleased to announce a further cornerstone investment by its institutional investors led by the NWF. This investment, which is subject to, inter alia, shareholder approval, enables the company to continue to develop a secure supply of lithium for the UK economy.

The new investment comprises £35m of equity funding from existing institutional investors, including up to £31m from the National Wealth Fund, designed to advance the company’s projects to the next stage of development. The company’s long standing institutional investor, TechMet, has chosen to participate alongside NWF in this funding round.

The funding, together with any additional funds raised from the forthcoming crowdfunding, will be used to progress Cornish Lithium’s Trelavour Lithium Project towards a construction decision and its Cross Lanes Geothermal Lithium Project towards commercial drilling. Importantly, it will enable Cornish Lithium to complete the Feasibility Study for its Trelavour Lithium Project and finish testing of its low-carbon processing technology at its Trelavour Demonstration Plant.

The £35m of equity funding that has been secured from NWF and TechMet demonstrates the investors’ continued confidence in Cornish Lithium’s progress towards production of battery-grade lithium in the UK. The funding is subject to various conditions including, inter alia, shareholder approval at a General Meeting scheduled for 8 October 2025, sign off from the UK Takeover Panel and the relevant approvals being obtained under the National Security and Investment Act 2021.

The NWF made its first equity investment in Cornish Lithium in August 2023, with the UK Government’s principal investor and policy bank committed to supporting supply chain

resilience for critical minerals in the UK, whilst crowding in private investment to boost growth.

In order to allow Cornish Lithium’s wider community of shareholders and supporters the chance to invest in the next stage of growth, the company intends to launch a new fundraising round on the Crowdcube platform. The crowdfunding campaign is expected to launch shortly after the necessary shareholder approvals have been obtained following a General Meeting of the company’s shareholders on 8 October 2025. The crowdfunding will give existing holders of ordinary shares in the capital of the company priority to subscribe for ordinary shares and thereafter, subject to there being sufficient headroom under the applicable laws, new investors will also be invited to invest.

Building on the successful commissioning of the company’s Demonstration Plant and the securing of planning permission for the Cross Lanes Geothermal Lithium Project, today’s announcement marks another important milestone in Cornish Lithium’s journey towards commercial production. Jeremy Wrathall, Founder and Executive Chairman, commented:

“We are delighted to have the continued backing of NWF and TechMet, and to be able to offer our wider shareholder base the opportunity to invest alongside them. This funding marks an exciting step forward for Cornish Lithium as we move closer to construction decisions at our flagship projects. We have made significant progress since our last fundraising round and these new funds will enable Cornish Lithium to continue the journey towards securing a supply of lithium for UK industry and to support development of the domestic battery industry.”

Ian Brown, Interim CEO at NWF commented:

“A resilient domestic supply chain of lithium is critical as we transition towards net zero. Our financing will help Cornish Lithium progress towards commercial production, creating good year-round jobs, boosting local economic growth and helping ground Cornwall as an industrial cluster for critical minerals.”

Brian Menell, Chairman and CEO of TechMet, commented:

“Cornish Lithium and its flagship projects will play an important role in developing a secure, resilient supply of lithium for the UK, Europe, and the U.S. to feed the cornerstone industries of the 21st century economy. TechMet is proud to continue our support alongside the NWF.” For further information, visit cornishlithium.com.
