New 3D Model Highlights Structural Controls on Copper Mineralisation

Alford East Copper-REE Project, South Australia

The directors of Thor Energy PLC ("Thor" or the "Company") (AIM, ASX: THR, OTCQB: THORF) are pleased to share Thor's updated 3D Geological Model, incorporating the recently completed Ambient Noise Tomography ("ANT") surveys by Fleet Space Technologies ("Fleet") for the Alford East Copper - Rare Earth Element ("REE") Project in South Australia.

Highlights:

§ Fleet's ANT survey results provided valuable insights into the lithological and structural setting of the Alford East Copper oxide and REE Project.

§ Deeply weathered troughs in areas of unaltered metamorphic rocks were found to be associated with zones of faulting, deep oxidation and intrusives at depth.

§ The ANT surveys confirm the significance of the prominent north-northeast (NNE) structure associated with copper oxide mineralisation (Figure 1).

§ The combined resultant 3D Model provides targeted criteria for extensions to existing mineralisation and potential for new discoveries of oxide copper-REE mineralisation.

Nicole Galloway Warland, Managing Director of Thor Energy, commented:

"The 3D ANT Modelling has provided significant lithological and structural insights into the Alford East Project area. Combining this information with Thor's dataset has led to an exciting new 3D Model, with a newfound understanding of the Alford East structural setting and mineralisation controls. This has provided the Company with a refined targeted strategy, focusing future drilling on areas with potential high-grade oxide copper-gold and REE mineralisation.

"The model also provides greater insight into historical, negative drill results that led to major explorers leaving the area."

Next Steps:

1.    Drill preparations and drilling

2.    Pump testing for ISR assessment push-pull work

3.    Continue quarterly groundwater testing

3D ANT and Structural Model

After the acquisition of ANT data by Fleet across the northern part of the Alford East project in 2023 (Figure 6), Thor engaged with the consultant, Doreen Mikitiuk, DXplorer to review and update the current Alford East structural model and geological interpretation of the survey areas.

In preparation for the new structural interpretation, historic logging codes were simplified and grouped using information acquired from reports, core photos and Hylogger data. Lithology groups were based on the lithogeochemical assessment of multi-element assays of the 2021 diamond core drillholes and reassay of selected historic core, which was completed in 2023.

The 3D ANT survey provided clearer understanding of the structural setting of the Alford East area (Figure 2). With improved knowledge of geology and weathering through the review of lithological information, the ANT results mapped localising faults and intrusives at depth. Deeply weathered troughs in areas of sedimentary rocks were found to be associated with zones of faulting, deep oxidation and intrusives at depth.

With the newly gained understanding of the geological and structural setting, targeting criteria for primary copper and oxide mineralisation were developed providing excellent opportunities for the discovery of new copper and REE mineralisation, which may have been missed by previous explorers.

Key observations from the 3D Modelling include:

1)         The highest-grade copper oxide mineralisation is commonly hosted in pelitic and carbonaceous sediments, with faults facilitating deeper weathering and alteration. For example, MRE Domain Area 6, 7 and 8 (Figure 1, 4 and 5).

2)         Mineralisation in Area 5 is predominantly adjacent to fault zones within dioritic and/or felsic intrusives and pelitic sediments. Host rocks are more competent and brittle and may have concentrated oxide mineralisation to brecciated zones along faults/shears. Lower grade intersected towards the base of drillholes is found within shears in more competent diorite.

3)         Psammites seem to be less favourable host rocks for copper oxide mineralisation.

4)         Mineralised features are subsequently offset by regional scale east-northeast (ENE) dextral strike slip faults and associated northwest (NW) trending faults.

5)     Zones of low velocity at shallow depths (approx. 70m) correlate with pelitic sediments in trough-like structures which are in closely related to higher velocity intrusives at depth (Figure 4 and 5). These higher velocities suggest intermediate, rather than felsic composition.

ANT Geophysics Surveys:

Two comprehensive ANT surveys were executed at the Alford East Project, covering the northern portion of the Mineral Resource Estimate Domains (Figure 2 and Figure 6). The surveys were designed to delineate the low-velocity, weathered 'troughs' that are known to host the oxide copper-gold and REE mineralisation within the Alford Copper Belt (Figure 5). The oxide copper-gold and REE mineralisation within the Alford Copper Belt is associated with rocks that are significantly less dense with lower seismic velocity than the surrounding fresh units.

The data collected from these two surveys was subject to extensive processing, leading to the development of a high-resolution 3D seismic velocity model of the subsurface. This model has revealed key features, such as regions with lower velocity within a high-velocity basement, inferring a 3D geometry of the interpreted variably weathered trough and a sheared metasedimentary basement, which is expected to host mineralisation (Figure 2).

Alford East Project Background:

The Alford East Copper-REE Project is located on EL6529, where Thor holds an 80% interest from unlisted Australian explorer Spencer Metals Pty Ltd, covering portions of EL6255 and EL6529 (Figure 6) (ASX/AIM: 20 November 2020).

The Alford East Project covers the northern extension of the Alford Copper Belt, located on the Yorke Peninsula, South Australia. 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 6), Gawler Craton, South Australia.

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

▪              71, 500oz of contained gold

Note: MRE reported on oxide material only, at a cut-off grade of 0.05% copper which is consistent with the assumed In-Situ Recovery technique.

REE results were later reported from the 2021 diamond drilling program, with significant drill intercepts (>500ppm TREO^[1]) including (THR: ASX/AIM 26 April 2023):

o 21AED005:                 36.7m @ 1568ppm (0.16%) TREO & 1.2% Cu from 6.3m,

including        11.8m @ 2095 ppm (0.21%) TREO and 1.2% Cu from 10m,
