Thor Energy PLC

("Thor" or the "Company")

Quarterly Activities and Cash Flow Report Q2 2026

Strong balance sheet with cash position of A$2,815,000 at June 30, 2026
In addition, the first of three annual deferred completion payments of A$1,312,500 is expected to be received on 1 September 2026

Thor Energy PLC (AIM, ASX: THR, OTCQB: THORF) is pleased to report on its activities for the Quarterly period from 1 April to 30 June 2026.

Andrew Hume, CEO and Managing Director, Thor Energy Plc, commented:

"The past quarter has strengthened our exploration model and confirmed our conviction that the HY-Range Project is a significant geological opportunity for us to explore further. We recorded natural hydrogen concentrations of up to 3% during our Phase-2 geochemistry survey, which surpassed our initial expectations. More importantly, the rigorous scientific methodology we applied to this programme gives us confidence that our acreage, our play-based exploration approaches, and our enthusiasm for this project have been warranted thus far.

"With these strong results increasing our confidence in the project, we are now taking the next critical step. Awarding a major 464 line-kilometre 2D seismic survey to Velseis will allow us to illuminate the subsurface geology of our highest-priority focus areas for the very first time, thereby linking our surface data to the deep basement rocks that generate the hydrogen.

"The strategic and successful divestment of our legacy non-core assets means this milestone seismic acquisition is fully funded by our existing cash reserves. We are moving rapidly toward defining our maiden drill targets and look forward to an exciting second half of the year as we drive the HY-Range project toward the drill bit."

HY-RANGE PROJECT - SOUTH AUSTRALIAN NATURAL HYDROGEN AND HELIUM

Phase-2 Soil Air Geochemistry Survey

The Company announced the preliminary results of its Phase-2 soil air geochemistry survey at the HY-Range Project (RSEL 802) during the quarter, recording natural hydrogen readings of up to 3% (30,000ppm), approximately 60,000 times background levels, and validating three of the Company's highest-priority exploration focus areas: Mallala, Lochiel and Crystal^[1]. The survey builds on and materially exceeds Phase 1 results, with consistently repeated hydrogen anomalies ranging from several hundred to several thousand times background across the key target areas, significantly increasing confidence in the scale and continuity of the natural hydrogen system.

Evolved sampling techniques, in which depth, duration and material variables were tested alongside controls, strongly indicate the presence of highly active natural hydrogen generation and substantially reduce the risk of sampling error or anthropogenic (human-made) contamination. The anomalously high surface geochemistry aligns with the Company's geological models and the crustal-scale basement architecture, faulting and focusing mechanisms considered necessary to deliver economic volumes of natural hydrogen. The Phase-2 results provide further validation of the Company's exploration model and increase our confidence in the HY-Range Project ahead of the next phase of exploration.

Following these highly encouraging results, the Company began planning for a large-scale 2D seismic acquisition programme designed to image the subsurface geology, refine structural interpretations and identify priority drilling targets across the HY-Range Project. The programme marks the next critical step towards testing the project's natural hydrogen potential through drilling.

2D Seismic Acquisition Contract

Following a comprehensive bid evaluation, the Company signed a Letter of Award with Velseis Pty Ltd, a leading Australian seismic contractor, for an onshore 2D seismic acquisition survey across RSEL 802^[2]. The programme will acquire approximately 464 line-kilometres of 2D seismic data, targeting the Company's highest-priority zones within the Torrens Hinge Zone, with acquisition expected between Q3 and Q4 2026.

The seismic data will be integrated with the Company's existing subsurface models, gravity, magnetic and passive datasets, and with the Phase-2 geochemistry results, to provide depth control, reveal the nature of the hydrogen and helium-generating basement rocks, map faulting that acts as a migration control, and confirm and mature targets for definitive exploration drilling.

The programme is fully funded from existing cash reserves following the Company's recent non-core asset divestments. The Company will move to a full contract in the coming weeks and will provide further timing updates to the market once all approvals and detailed planning are complete.

FINANCE AND CASH MOVEMENTS

Cash Movement:

Net cash outflows from Operating and Investing activities for the quarter of $501,000, which included outflows of $66,000 directly related to exploration activities. Thor ended the quarter with a cash balance of $2,815,000, reflecting continued disciplined management of the Company's cash reserves following its recent portfolio divestments.

In addition to the current cash reserves of $2,815,000, the agreement announced on 16 September 2025, which outlined the Term Sheet to Sell FRAM Joint Venture of which Thor owned 75% to ASX-Listed Tivan Limited for A$8,750,000, stipulates that Thor is due to receive the first of three annual deferred completion payments of A$1,312,500 on 1 September 2026.

Cashflows for the quarter include payments of $138,500 to Directors, comprising the CEO-Managing Director's salary and the Non-Executive Directors' salaries/fees.
