Bolivian Brines Qualification for 3^rd Phase of the 2024 Convocatoria

Clontarf Energy plc (AIM: CLON), continues to progress its activities in Bolivia, and is pleased to report the following update:

Further to the Company's 6 and 18 March 2024 announcements, the Bolivian State Lithium Company ("YLB") received Clontarf's technical materials in relation to Phase 2 of the Call for Bids ("convocatoria") for the seven priority salares (salt pans) in Southern Bolivia.

YLB confirmed on 14 May that Clontarf is one of 21 companies approved to enter Phase 3 of the (5 phase) process.  Phase 2 dealt in detail with the technical aspects of state-of-the-art Lithium extraction technologies, especially emerging Direct Lithium Extraction techniques.

Phase 3 of the convocatoria process will include confirmation of the Clontarf/NEXT-ChemX JV partnership's financial capacity, which include a review of the last 5-years' accounts, and a risk-rating. As a reminder to Shareholders, Clontarf has worked closely with its JV technology partner NEXT-ChemX since 2022.

At the suggestion of the European Commission, Clontarf has now broadened its "Team Europe" partnership to include financing and offtake partners representing key OEM manufacturers in the German Mittelstand.  Endorsement from one of the world's leading groups of high tech, battery-quality Lithium offtakers is heartening.

The Company further acknowledges the European Commission's leadership and strong support for the European companies involved, including initiating high-level negotiations over infrastructure financing, and issuing a Letter of Comfort for the qualified European companies, which may prove critical in overcoming any remaining financial challenges. Clean, Green Lithium from brines may be classified as a strategic project under the EU's Critical Resource Minerals Act.

Further updates will be provided, as appropriate, in accordance with necessary clearances from the authorities.

David Horgan, Chairman, commented: "Bolivia offers potential for large volumes of high-purity, cleanly produced battery-grade Lithium for the European market.

We must go where the resources are: there are many sources of hard-rock Lithium worldwide, but their mining and processing is often dirty and expensive. Only Lithium brines offer the potential for clean, Green low-cost and high quality product."

"Europe needs offtake.  Chinese dominance of Rare Earths, and graphite mining, together with Chinese control of Lithium and Cobalt processing, puts western supplies in jeopardy.  We can no longer rely on free markets to ensure supply.  European vulnerability is further exacerbated by protectionist moves in NAFTA, and Japan.  The EU has little choice but to secure its lifelines."

"No one company or country has the weight to grapple with China and NAFTA - it must be a "Team Europe" effort.  Accordingly, we sought EU institutional cover and, where possible, minority investments by Member States' entities to guard against expropriation."

"Finance is best linked to offtake.  We are now cooperating on downstream and financing activities with Germany's leading Mittelstand representative body.  All markets are important, but Germany's OEM market is critical."

"We have worked for many years on Bolivian brines.  But the convergence of fast demand growth, rising standards and geopolitical imperatives now accelerates progress."
