Thor Energy Plc
("Thor" or the "Company")
ANT Geophysical Surveys Commence
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 announce the commencement of Ambient Noise Tomography ("ANT") geophysical surveys, in partnership with Fleet Space Technologies ("Fleet"), at the Alford East Copper-REE Project in South Australia.
Highlights:
▪ The ANT surveys are designed to delineate the low-velocity, weathered 'troughs' that host the oxide copper-REE mineralisation within the Alford Copper Belt (Figure 2). They will be completed over the next few weeks.
▪ Future drilling will be concentrated on these targets, characterised by low seismic velocity, to intersect higher-grade oxide copper-gold mineralisation hosted in units conducive to the possibility of In-Situ Recovery ("ISR").

Nicole Galloway Warland, Managing Director of Thor Energy, commented:
"The commencement of the low-impact ANT geophysics surveys over the Alford East copper-REE Project, as part of the collaborative partnership with Fleet Space Technologies, is a key step in accelerating our exploration and ISR assessment strategy at our Alford East Copper-REE Project.
"Fleet will integrate the data from the ANT surveys, and in conjunction with Thor's 3D geological model, it will result in a revised model to support drill targeting of higher-grade copper and REE mineralisation along strike of our mineral resource estimate and in new zones of the Alford Copper Belt.
"The results from the surveys will help us become more precise in our future drilling campaigns, which will help us reduce our environmental footprint. We look forward to keeping the market updated as the results come in."
Next Steps
1. Continue the ANT Surveys with the deployment of Exosphere geodes (Figure 1, Photo 1 and 2)
2. ANT Surveys are estimated to take 3-4 weeks
3. Modelling of ANT results, incorporating Thor's 3D model and using AI to extrapolate controlling structures along the Alford Copper Belt (October)
4. Target generation from the final 3D Model (November)
5. Drill preparations and Drilling (Early 2024)

EXOSPHERE BY FLEET
scans the ground using an advanced ANT seismic tomography technique. This technique consists of laying an array of approximately 100 lightweight, battery-powered surface sensors called Geodes (Photo 1 and Figure 1) at a spacing of approximately 150 m, to measure faint, naturally occurring environmental seismic vibrations in the ground (caused by ocean waves, weather, and traffic) in near real time, over a 7 day-period. The data is transmitted through satellites and then can be processed rapidly.
A series of surveys over the Alford East Project will be completed to successfully delineate the low-velocity, weathered 'troughs' that host the oxide copper-REE mineralisation within the Alford Copper Belt (Figure 2). Known copper-oxide copper 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 survey will compare and integrate the subsurface ANT results with geological information (surface geochemistry, drilling, and historic geophysics) that has been compiled by Thor. The resultant 3D model will provide a refined targeted strategy, focusing future drilling in areas with potential high grade oxide copper-REE mineralisation.

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
