Thor Energy PLC

("Thor" or the "Company")

Thor Energy Plc to Appoint Director to EnviroCopper Limited Board

Thor Energy Plc (AIM, ASX: THR, OTCQB: THORF) is pleased to announce that Lincoln Moore, Non-Executive Director of Thor Energy Plc, has been appointed as a director of EnviroCopper Limited ("ECL"), a copper-focused in-situ recovery ("ISR") specialist company in which Thor holds a 20% interest.

ECL was established in 2017 as an in-situ copper recovery ("ISCR") specialist focused on its South Australian projects at Kapunda (150km North of Adelaide) and Alford West (180km NE of Adelaide in the Yorke Peninsula). ECL's specialist team is pioneering ISCR technology development through collaboration with leading universities, research institutions, Commonwealth Government grants, seed investment and partnerships with BHP. ECL is a leader in ISCR and associated gold and rare earth element ("REE") recovery, driving the technology and economic viability of this low environmental impact approach to metals extraction.

Recently, ECL entered into a collaborative agreement with a large international firm, which invested A$3.5m to progress the Kapunda and Alford West (Yorke Peninsula) projects to feasibility ("External Investment of A$3.5m into ECL & its Copper Projects").

Thor's decision to reestablish board representation reflects its ongoing support for ECL's technical progress, the strategic importance of copper in the global energy transition, and the profitable, environmentally responsible potential of ISR copper, gold and REEs. With copper and gold trading near all-time highs, the macroeconomic backdrop further supports the attractiveness of advancing high-quality, development-ready copper, gold and REE assets. Mr Moore's appointment to the ECL board provides Thor with strategic oversight of its 20% investment and will enable closer strategic alignment as ECL progresses its projects.

Bordering Alford West, Thor holds an 80% interest in Alford East, with both projects located on the Copper Coast of the Yorke Peninsula within South Australia's historic copper districts and the prolific Olympic Copper-Gold Province. Both projects are interpreted as metasomatised iron oxide copper‑gold systems with significant supergene enrichment within oxide-dominated mineralisation. Located in a world-class copper-gold province, these near-surface oxide deposits are considered particularly amenable to low-impact ISR techniques.

Thor looks forward to supporting ECL in the next phase of development and to participating in the potential value creation from a successful copper ISR platform in South Australia.
