("Thor" or the "Company")
High-Grade Uranium Intercepts at Groundhog Prospect
Wedding Bell and Radium Mountain Projects, USA
The directors of Thor Energy Plc ("Thor") (AIM, ASX: THR, OTCQB: THORF) are
pleased to announce the final downhole uranium gamma results for the reverse
circulation ("RC") drilling program, at the Company's 100% owned Wedding Bell
and Radium Mountain Projects, located in the historic uranium-vanadium mining
district within the Uravan Mineral Belt, southwest Colorado, USA (Figure 1).
Drilling Highlights:
§ Downhole gamma logging returns up to 6,885ppm (0.69%) eU(3)O(8) uranium along strike of the historic mine working at Groundhog Mine (Figure 1 and Table A).
§ Significant uranium downhole gamma results above 2000ppm (0.2%) eU(3)O(8) include:
§ 23WBRA020 0.9m @ 6885ppm (0.69 %) eU(3)O(8) from
82.66m
§ 23WBRA019 0.3m @ 3362ppm (0.34 %) eU(3)O(8) from
90.22m
§ 23WBRA011 0.5m @ 3186ppm (0.32 %) eU(3)O(8) from
76.2m
§ 23WBRA016 0.8m @ 1954ppm (0.20%) eU(3)O(8) from
67.4m
§ The completed RC program comprised 23 shallow drillholes totalling 2,737m (Figure 1-8, Table B), with geological logging visually identifying favourably reduced sands in all drillholes.
§ Uranium and Vanadium assay results pending.
§ Further geological and mineralisation interpretations to follow.

Nicole Galloway Warland, Managing Director of Thor Energy, commented:
"These results confirm our expectations that we would achieve shallow
high-grade uranium from the drilling program, highlighting the significant
potential and exciting growth opportunities of our Wedding Bell and Radium
Mountain uranium projects.
"A sample submission will be sent to the Australian Laboratory Services, in
Vancouver, for physical uranium and vanadium assays results. We look forward
to updating the market in due course."

Wedding Bell and Radium Mountain Project, Colorado:
The RC drill program comprised 23 shallow drillholes, totalling 2,737m. It was designed to target uranium and vanadium mineralisation within the Salt Wash Sandstone Member (sandstone/mudstone) of the Morrison Formation (Figure 1, and 3). This is the primary lithology for historic uranium and vanadium production in the Uravan Mineral Belt. The program successfully identified shallow, uranium mineralisation (visual geological logging and downhole gamma) in all holes drilled at Section 23, Rim Rock Mine and Groundhog Mine (Table A). Uranium mineralisation is hosted within the reduced sands close to the oxidation/reduction contact, with vanadium mineralisation to be determined by follow-up sample analysis of the anomalous zones.
Groundhog Mine area drilling comprising 7 drillholes, was designed to test areas along strike of historic mine workings predominately in the second and third sandstone rim. 23WBRA020 returned the highest uranium intercept of 0.69% eU3O8 (Figure 4) within a grey reduced sandstone (Figure 4 and 6). Further work is required on correlating these results with historic mine workings and 2022 drilling, to delineate mineral resources.
Drilling at Rim Rock Mine area (7 drillholes) has identified high-grade zones of up to 0.32% eU(3)O(8) uranium adjacent to, as well as along strike from the historic workings (Figure 5 and 7). Uranium mineralisation appears here to be concentrated in the third sandstone rim of the Salt Wash Sandstone, approximately 60m below surface (Figure 3, 5 and 7). Further work is required on correlating these results with historic mine workings and 2022 drilling, to delineate mineral resources.
Section 23 is an underexplored area with no historic workings. The drilling (9
drillholes) was designed to test stratigraphic extensions to mineralisation in
the Salt Wash Sandstone, targeting the uranium mineralisation identified from
the first pass drilling program in 2022, as well as testing a portion of the
airborne radiometric anomalies (Figure 8). The initial data review has
identified uranium mineralisation in all four sandstone rims (massive,
laterally continuous, ledge-forming sandstone layers, interbedded by thin
siltstone and clay layers) within the Salt Wash Sandstone Member, increasing
the potential for multiple mineralised zones in this area (Figure 1-3).
Samples from anomalous zones in each drillhole will be sent to ALS in Canada
for full geochemical analysis including uranium and vanadium assays.

About Thor Energy Plc
The Company is focused on uranium and energy metals that are crucial in the
shift to a 'green' energy economy. Thor has a number of highly prospective
projects that give shareholders exposure to uranium, nickel, copper, lithium
and gold. Our projects are located in Australia and the USA.
Thor holds 100% interest in three uranium and vanadium projects (Wedding Bell,
Radium Mountain and Vanadium King) in the Uravan Belt in Colorado and Utah,
USA with historical high-grade uranium and vanadium drilling and production
results.
At Alford East in South Australia, Thor has earnt an 80% interest in oxide
copper deposits considered amenable to extraction via In Situ Recovery
techniques (ISR). In January 2021, Thor announced an Inferred Mineral Resource
Estimate¹. Thor also holds a 30% interest in Australian copper development
company EnviroCopper Limited, which in turn holds rights to earn up to a 75%
interest in the mineral rights and claims over the resource on the portion of
the historic Kapunda copper mine and the Alford West copper project, both
situated in South Australia, and both considered amenable to recovery by way
of ISR.²³
Thor holds 100% of the advanced Molyhil tungsten project, including measured,
indicated and inferred resources⁴, in the Northern Territory of Australia,
which was awarded Major Project Status by the Northern Territory government in
July 2020. Thor executed a A$8m Farm-in and Funding Agreement with
Investigator Resources Limited (ASX: IVR) to accelerate exploration at the
Molyhil Project on 24 November 2022.(6)
Adjacent to Molyhil, at Bonya, Thor holds a 40% interest in deposits of
tungsten, copper, and vanadium, including Inferred resource estimates for the
Bonya copper deposit, and the White Violet and Samarkand tungsten deposits.
⁵ Thor's interest in the Bonya tenement EL29701 is planned to be divested as
part of the Farm-in and Funding agreement with Investigator Resources
Limited.(6)
Thor owns 100% of the Ragged Range Project, comprising 92 km(2) of exploration
licences with highly encouraging early-stage gold and nickel results in the
Pilbara region of Western Australia.

Thor's property position consists of 199 unpatented mining claims (approx.
1,663Ha), leased from underlying owners.
If Thor meets its' contractual obligations and keeps the claims in good
standing with the US, then the security of tenure should be good.
Depending on the location of the drill holes, the license to operate in the
area is a function of permitting at differing levels of government (Local,
State and Federal). The holes were in two contiguous Counties (San Miguel
and Montrose). In addition to the normally required State and Federal
permitting, San Miguel County imposes its' own set of regulations. Montrose
County, on the other hand, is content to defer to the State and Federal
governments. To date, Thor has met those permitting requirements.
Exploration done by other parties · Acknowledgment and appraisal of exploration by other parties. There are no systems of consistent data archiving for mineral exploration or
exploitation done under the Mining Law on Federal or on other lands within the
State of Colorado. Furthermore, with some exceptions, there was not, nor is
not, a requirement that explorers provide copies of their data to governmental
agencies. That data was retained by private entities. It now exists in a
piecemeal manner, with the data having been discarded, abandoned or available
by vendors that managed to acquire and store some of it over the years.
Thor's properties have bountiful surface evidence of historic drill
exploration, and in some cases, mining exploitation, which appears to be
mostly from the 1950's through the early 1970's. There are several mines
located in the western portion of the property. Unpublished reports list
these mines as producing, in aggregate, over 700,000 lbs (318,181 kg) of
uranium. To the author's knowledge, very little of the historic drilling or
mining data is available to Thor, and certainly not enough to help guide an
exploration program. Anecdotal evidence suggests that some of the work on
the property was done by Union Carbide (now defunct), the largest company that
worked in the Uravan Mineral Belt.
Geology · Deposit type, geological setting and style of mineralisation. According to the USGS Bulletin 1693 (Cox, D.P., and Singer, D. A., eds.,
1986), the Deposit Model for the project is Sandstone Uranium - Tabular
