("Thor" or the "Company")

Ragged Range Project, WA

Airborne Magnetic and Radiometric Survey Commences

The directors of Thor Mining Plc ("Thor") (AIM, ASX: THR, OTCQB: THORF) are pleased to announce the commencement of a close spaced airborne survey over the north-eastern portion of the Company's 100% owned Ragged Range Project, located in Eastern Pilbara, Western Australia.

Project highlights:

-- High resolution close spaced airborne magnetics survey commences over the north-eastern portion of tenure, covering E46/1393 and E46/1340 (Figure 1). This survey will complement the 2021 survey to provide coverage over the entire Ragged Range Project.

-- The airborne magnetic and radiometric survey is designed to map out the key lithological boundaries, potential pegmatites and prospective structures controlling mineralisation associated with copper-gold mineralisation at Kelly's Prospect.

-- Following the completion of the airborne geophysical survey, the next exploration step is to commence immediately; the continuation of mapping and sampling in the lithium prospective goldilocks zone, rock chip sampling of prospective structures at the Kelly's Cu-Au Prospect and the design of drill sections to test the Kelly's South gold zone.

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

"This airborne survey will ensure full coverage of tenure with high resolution, close spaced magnetics data, which is critical to the understanding of lithological boundaries and structural controls on mineralisation. This will allow Thor to focus on further developing its geological models in this greenfield area.

"The airborne survey will extend over the Kelly's copper-gold prospect where we have recently highlighted, through rock chip sampling, exciting copper and gold values along strike of the historic copper workings."

The Ragged Range Project, located in the prospective Eastern Pilbara Craton, Western Australia, is 100% owned by Thor Mining (covering E46/1190, E46/1262, E46/1355, E46/1340 and recently granted E46/1393, Figure 1).

The high resolution, close spaced airborne magnetics survey covers the remaining north-eastern portion of the tenure, covering E46/1393 and E46/1340 (Figure 1); now giving Thor full coverage of the tenure with close spaced magnetics and radiometrics data (Figure 1). The survey is being flown by Thomson Airborne Pty Ltd and is anticipated to take 2 to 3 days to complete.

The airborne magnetics survey is designed to map out lithological boundaries, potential pegmatites and prospective structures controlling mineralisation. The copper and gold mineralisation at the Kelly's Prospect is initially interpreted as shear hosted mineralisation associated with the dacitic Boobina Porphyry and the Euro Basalt (Figure 1).

This announcement is authorised for release to the market by the Board of Directors.
