The Ragged Range Project, located in the prospective Eastern Pilbara Craton, Western Australia is 100% owned by Thor Mining - (E46/1190, E46/1262, E46/1355, E46/1340) with the recent additional tenure surrounding the gold anomalous zones, E46/1393 (application).

Sterling Prospect

Thor completed a further 369 infill soil samples in July over two portions of the Sterling Prospect, Sterling Central and Sterling South (Figure 2), as a follow-up to a reconnaissance soil program (THR:ASX announcement 23/06/21) and high-grade gold stream results (up to 2.2g/t Au) reported from sampling in 2019 and 2020 (THR:ASX announcement 1/12/2020).

The infill soil samples were collected at a 25m x 100m spacing over priority areas with anomalous gold results from the initial reconnaissance program.  At each site and consistent with the previous soil program, two samples were collected at each site, and both sieved to -2mm. The first sample of approximately 2kg was crushed at the Intertek lab in Perth and a sub-split assayed for Au by an aqua regia method AR25 and multi-element assaying by four-acid digest with MS25 finish.  The second sample 1kg Bulk Leach Extractable Gold (BLEG) sample was assayed by method CN1000 for gold only.

Soil and Pan Concentrate Results

The infill soil results returned BLEG soil values up to 348ppb and 153ppb Au (21RRS777 and 21RRS437 respectively), with over 61 samples reporting significantly above a background of approximately 5ppb Au. Five stream sediment samples were collected using a <2mm sieve and panned to check gold anomalism. Samples 21RRST016 (74.1g/t Au) and 21RRST017 (0.35g/t Au) were panned approximately 100m down slope, in a small creek from soil sample 21RRS777. Gold was observed in both samples. Two creeks (21RRST018 and 21RRST019) were sampled, draining the major contact to the south of the Sterling South soil grid. No gold was observed in the pan. One sample was also collected from a high BLEG (111ppb Au) sample from previous stream sediment sampling. One speck of gold was panned with the sample 21RRST020 reporting 3.58g/t Au.

Only thin residual soils overlie the Euro Basalt extending westward over the ultramafic Dalton Suite, faulted contact and the tenor and consistency of the BLEG results is considered outstanding.

Significant soil results are summarised in Table A.

Pan concentrate samples are found in Table B.

These latest soil results, combined with the initial soil program earlier in the year, have now identified several continuous anomalous gold zones each warranting drill testing, with some zones extending over 1km long at both the Sterling Central and Sterling South areas. Soil anomalies remain open to the north and south, with follow up infill sampling planned to investigate these areas further.

The gold anomalism generally strikes slightly oblique to the Euro Basalt and Dalton Suite contact and suggests that gold mineralisation is controlled by minor faults and structures, associated with this major structure.

Gold mineralisation appears to be associated with highly foliated basalts with quartz boudinage (quartz-fuchsite veins) and zones of carbonate alteration

Next Steps

A 3,000m maiden RC drilling program is scheduled to commence in early October to drill test up to eight of the priority gold in soil and stream anomalous targets identified at Sterling Central and Sterling South prospects.  The drilling is fully permitted with the drilling contractor about to mobilise.

Thor Mining was awarded A$160,000 from the Western Australia Government under the EIS Co-funded grants program to drill test gold anomalies at the Sterling Prospect.

Concurrent with the drilling program, infill soil sampling covering anomalous zones open at Sterling Central and Sterling South will be completed. In addition, regional gold targets, including to the northwest and southeast of Sterling prospect, the granitoid contact in the north, plus the copper-gold area in the northeast (Kelly/Ryan Prospects), will be followed up with reconnaissance stream and soil geochemistry programs.  Government and Company geophysics are being used in conjunction with the geochemical data, to assist with structural and lithological targeting.

Thor Mining PLC (AIM, ASX: THR; OTCQB: THORF) is a diversified resource company quoted on the AIM Market of the London Stock Exchange, ASX in Australia and OTCQB Market in the United States.

The Company is advancing its diversified portfolio of precious, base, energy and strategic metal projects across USA and Australia. Its focus is on progressing its copper, gold, uranium and vanadium projects, while seeking investment/JV opportunities to develop its tungsten assets.

Thor owns 100% of the Ragged Range Project, comprising 92 km² of exploration licences with highly encouraging early stage gold and nickel results in the Pilbara region of Western Australia, for which drilling is planned in the second half of 2021.

At Alford East in South Australia, Thor is earning an 80% interest in copper deposits considered amenable to extraction via In Situ Recovery techniques (ISR). In January 2021, Thor announced an Inferred Mineral Resource Estimate of 177,000 tonnes contained copper & 71,000 oz gold¹.

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% interest in two private companies with mineral claims in the US states of Colorado and Utah with historical high-grade uranium and vanadium drilling and production results.

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.
