High-grade Rare Earth Discovery within IOCG Copper Project
Alford East Copper-Gold Project, South Australia
The directors of Thor Energy Plc ("Thor" or the "Company") (AIM,
ASX: THR, OTCQB: THORF) are pleased to announce new Rare Earth
Element (REE) drill results from a review of the previously
announced 2021 Copper and Gold drilling at the Alford East Project,
South Australia (SA).

including 11.8m @ 2095 ppm (0.21%) TREO and 1.22% Cu from 10m, and

o 21AED001: 16.8m @ 1721ppm (0.17%) TREO and 0.5% Cu from 91.4m
o 21AED006: 29m @ 959ppm (0.1%) TREO from 20m, and
6.1m @ 1171ppm (0.12%) TREO and 0.1% Cu from 81m,
including 1.7m @ 3139ppm (0.31%) TRE0 from 84.3m
o 21AED004: 13.1m @ 1366ppm (0.14%) TREO and 0.5% Cu from 42.8m,

including 1.0m @ 2213ppm (0.22%) TREO from 19m
-- A REE review has revealed that eight out of nine of the 2021
diamond drill holes intersected wide zones of highly enriched REE's
in kaolin altered, copper rich oxide zones of IOCG style
mineralisation.
-- Mineralisation is open over a 5km trend as none of the
remaining historical drilling at Alford East, to the best of the
companies knowledge , has ever been assayed for REE's.
-- A full geochemical review of the historic drilling is now
underway to access the lateral extent of the REE potential within
the Alford Copper Belt , to generate drill targets and to fully
assess the economic potential of this discovery.
-- The kaolin association may represent an ionic style of REE
mineralisation, a highly valuable REE deposit class, often
characterised by favourable low-cost metallurgical recovery
compared with many other types of REE deposits.
-- Magnetic component (MREO) content of TREO up to 34%, see
Table A.
-- Alford East is strategically located approximately 150km
northwest of Adelaide.
Nicole Galloway Warland, Managing Director of Thor Energy,
commented:
"I am absolutely delighted to report these thick zones of
shallow, high-grade REE intercepts, found to be associated with
oxide copper-gold mineralisation at the Alford East Project.
" This batch of results compares very favourably in terms of
depth, thickness and grade to its peer group in the fledgling
Australian REE sector.
" Importantly , this discovery has significant potential to be a
large deposit based on the 5km lateral extent of the north-south
trending, structurally controlled troughs hosting IOCG
mineralisation . It is promising that aside from the nine 2021
diamond drill holes reported today, none of the other historic
drilling at Alford East is known to have ever been assayed for REE
content.
" Priority drill programme design is underway in conjunction
with detailed geochemical reviews of the historic drilling, along
with further studies on the nature of the REE mineralisation
encountered to date."

Rare Earth Element Drill Results
A review of the Alford East Project geochemical data, in
particular, the drilling results from Thor's 2021 maiden drilling
program (ASX/AIM: 22 February 2022), highlighted shallow high-grade
REE results associated with the oxide copper-gold mineralisation
(Figure 2- 5, Table A).
These wide zones of enriched REE occur in kaolin altered, oxide
zones of IOCG-style mineralisation (Figure 3-5).
Three drill hole cross-sections (Figure 3 - 5) illustrate the
REE mineralisation with the copper intercepts within the Mineral
Resource Estimate (MRE) AE-5 area (Figure 2), where Thor in 2021
drilled 9 HQ diamond drillholes whilst targeting oxide copper
mineralisation. The proximity to the key structure on the eastern
side of the sections suggests the REE mineralisation is
structurally controlled and associated with significant metasomatic
alteration and deep weathering or kaolinisation of host rocks.
The kaolin association may represent an ionic style of REE
mineralisation, a highly valuable REE deposit class, often
characterised by favourable low-cost metallurgical recovery
compared with many other types of REE deposits.
This zone of oxide mineralisation lies in the Alford Copper
Belt, which in this area, is a structurally controlled, north-south
corridor consisting of deeply kaolinised and oxidised troughs
within unweathered metamorphic units, on the edge of the Tickera
Granite (Figure 1), Gawler Craton, SA. A recently completed Ambient
Noise Tomography (ANT) survey over the adjacent Alford West project
successfully delineated the boundaries of the structures in that
area (ASX/AIM: 17 April 2023) (Figure 1).
Next Steps:
Continue to review the geochemical REE data, with selected
samples submitted to the Bureau Veritas laboratory for analysis,
for a supplementary REE package; along with mineralogy and
preliminary metallurgical work to determine the potential ionic
nature of the REE.

Alford East Project Background
The Alford East Copper-Gold Project is located on EL6529, where
Thor is earning up to 80% interest from unlisted Australian
explorer Spencer Metals Pty Ltd, covering portions of EL6255 and
EL6529 (Figure 1) (ASX/AIM: 20 November 2020).
The Alford East Project covers the northern extension of the
Alford Copper Belt, located on the Yorke Peninsula, SA. The Alford
Copper Belt is a semi-coherent zone of copper-gold oxide
mineralisation, within a structurally controlled, north-south
corridor consisting of deeply kaolinised and oxidised troughs
within metamorphic units on the edge of the Tickera Granite (Figure
1), Gawler Craton, SA.
Thor completed an inferred Mineral Resource Estimate (MRE) by
utilising historic drill hole information. Table C - (ASX/AIM: 27
January 2021):
-- 125.6Mt @ 0.14% Cu containing 177,000t of contained copper

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 Colorado and Utah, USA with historical high-grade uranium and
vanadium drilling and production results.
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.
At Alford East in South Australia, Thor is earning 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 Estimate(1). 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.(2)(3)
Thor holds 100% of the advanced Molyhil tungsten project,
including measured, indicated and inferred resources , 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. 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)
