Outstanding Geochemical Results Demonstrate Prolific Hydrogen and Helium
Systems at HY-Range Project in South Australia

 

Thor Energy plc ("Thor") (AIM, ASX: THR, OTCQB: THORF) is pleased to announce
positive results of its recent soil geochemistry study at its HY-Range project
(RSEL 802) in South Australia.

 

Highlights:

·    Positive results with significantly elevated hydrogen and helium

·    Several natural hydrogen values more than 1,000ppm, with highest
reading of 3,000ppm (approximately 6,000 times background values)

·    Helium detected up to 27ppm (greater than five times background
values)

·    Four high-grade focus areas identified for future exploration focus

·    This significantly advances prospect definition, ranking and site
selection for exploration drilling

 

Andrew Hume, Managing Director of Thor Energy, commented:

"The results from our geochemical survey at HY-Range (RSEL 802) are very
promising and effectively derisk the presence of active and potentially
prolific natural hydrogen and helium systems in our licence. This is a major
achievement and establishes the HY-Range project as a highly prospective
licence for natural hydrogen and helium exploration. The data is also proving
critical to high-grade the acreage and to define the highest potential areas
for natural hydrogen and helium. These findings allow us to focus our
resources effectively as we undertake necessary work to define and high-grade
drilling targets for exploration drilling. This is a very exciting development
for Thor Energy and our promising natural hydrogen and helium project."

 

Geochemical Survey Yields Highly Encouraging Results

Thor Energy recently acquired soil geochemical gas sampling (also known as
Soil Air, Soil gas analysis, or Soil vapor testing) across its HY-Range (RSEL
802) natural hydrogen and helium exploration licence in South Australia
(Figure 1). Analysis of the data has been performed and has yielded very
positive results, with a high percentage of elevated hydrogen values in
numerous areas of the licence, locally exceeding 1,000ppm in several
locations, and up to 3,000ppm at one sample point (compared to typical
background atmospheric values of 0.5ppm). Locally elevated helium readings
were also recorded up to 27ppm (compared to typical background atmospheric
values of 5ppm). Whilst soil gas sampling can be inherently prone to
anthropogenic hydrogen contamination and sample bias, the distribution of the
values strongly correlates with mapped geological features and supports the
natural origin of these highly elevated readings. Helium is not prone to
similar potential contamination risk, and as such, collectively, and when
taken in the context of regional geological and industry activity (Figure 2a),
these results provide striking evidence to prove the presence of both strong
natural hydrogen and helium generation and migration within RSEL 802.

 

The data has allowed the high grading of areas of significant interest within
the licence. Four principal focus areas have been high graded (Figure 2b),
these being:

 

·    Mallala area, located approximately 40 km north of central Adelaide

·    Locheil area, located in vicinity of the township of Locheil

·    Crystal area, an elongate area extending south southeasterly from the
township of Crystal Brook

·    Mt Lock area, an area 10 km northwest of the township of Jamestown

Figure 2a illustrates the location of HY-Range (RSEL 802) in the context of
nearby Petroleum Exploration Licences (PELs) and licence applications
(PELA's), as well as nearby down-hole hydrogen/helium occurrences.

Figure 2b illustrates the four priority focus areas (Blue polygons) in the
context of RSEL 802 licence (2(nd) term outline- black polygon).

 

 This data has significantly added to the understanding of hydrogen and
helium generation and migration systems within these areas. Future work will
be focused on and around these four areas, resulting in further prospect
definition, ranking and ultimately drilling of the most prospective and
highest value wells within these focus areas. Near-term work will consist of
ground-truthing these soil air geochemical results by acquiring increased
sample density geochemistry and by incorporating techniques to take samples at
deeper depths and/or longer durations, to better understand hydrogen and
helium systems and help signpost prospectivity.

 

Managing Director Promotion to Chief Executive Officer

Thor Energy Plc also announces that Thor Managing Director Andrew Hume, who
joined Thor Energy in February 2025, will assume the role of Chief Executive
Officer ("CEO") and Managing Director ("MD") with immediate effect. Since
joining, Mr Hume has overseen the successful conclusion of the acquisition of
Go Exploration, conducted critical fieldwork, relinquished low-priority
mineral exploration acreage, and secured three new co-located gas storage
licenses, adjacent to RSEL802, which offer a novel potential advantage for
hydrogen exploration and commercialisation in South Australia. Mr Hume's
remuneration remains unchanged.

 

In line with the plan, Alastair Clayton will resume the role of Non-Executive
Director Chairman.

 

Andrew Hume, incoming CEO of Thor Energy, commented:

"Alastair and I discussed a succession plan some time ago whereby the Company
would have one Executive Director, as is appropriate for the present size of
the Company. With much of the corporate restructuring now complete and our
HY-Range Project plans now accelerating, Alastair informed me that he wished
to resume his previous role as Non-Executive Chairman and that the Board had
requested that I take the role of CEO and MD, to which I gladly accepted."

 

The Board of Thor Energy Plc has approved this announcement and authorised its
release.

Appendix 1: Table of results

 

The following table provides raw sample values taken from soil air geochemical
analysis in RSEL 802. It should be noted that the technique of soil gas
analysis for hydrogen has inherent risk associated with anthropogenic
contamination, during the sampling process. Future follow-up work will aim to
ground-truth this data as well as to increase spatial density in key focus
areas.
