Thor Mining PLC (THR.ASX.L) Ragged Range Project, WA – 3,000m RC Drilling Program Commences

The directors of Thor Mining plc (AIM, ASX: THR, OTCQB: THORF) are pleased to announce the commencement of the maiden drilling program at the Company’s 100% owned Ragged Range Project, located in Eastern Pilbara, Western Australia.

Project highlights:

  • 3,000m reverse circulation (“RC”) drilling program underway
  • First ever drilling in the Ragged Range Project area to test robust gold anomalies
  • Up to 10 soil targets to be drill tested at the Sterling Prospect
  • Targeting Archaean shear hosted gold adjacent to significant regional structures
  • Thor Mining awarded A$160,000 from the Western Australia Government under the Government EIS Co-funded grants program to drill test stream and soil gold anomalies at the Sterling Prospect.

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

“After a series of successful and systematic stream and soil programs it is exciting to be commencing our maiden RC drilling program at the Sterling Prospect, Ragged Range.

These are robust geochemical targets in the central portion of the Sterling Prospect, within the highly prospective 13km structurally controlled gold anomalous corridor, defined by Thor associated with the mafic -ultramafic contact within the Kelly Greenstone Belt. With the program anticipated to take 4 to 6 weeks, drill results are expected from early November 2021.”

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

Since acquiring the Ragged Range project in late 2019, Thor have completed a series of systematic stream sediment programs over the tenure and an airborne magnetic survey, defining a 13km structurally controlled gold corridor – Sterling Prospect. High-grade gold stream results, including up to 2.2g/t Au were reported from sampling in 2019 and 2020 (THR:ASX announcement 1/12/2020).

As a follow up, two soil programs were completed over Sterling Central and Sterling South areas with BLEG soil values up to 348ppb and 153ppb Au (21RRS777 and 21RRS437 respectively), significantly above a background of approximately 5ppb Au. To validate these high gold soil anomalies a <2mm sieved stream panned concentrate with visible gold, reported up to 74.1g/t Au (Samples 21RRST016) in a pan concentrate- approximately 100m down slope, in a small creek from soil sample 21RRS777. (THR:AIM 7 October 2021).

These surface geochemistry surveys defined eight 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 (concurrent with drilling program).

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

RC Drilling Program

Thor’s maiden RC drilling program at Sterling Prospect, Ragged Range has commenced. The program is designed to test eight strong gold anomalies at Sterling Central and Sterling South prospects, defined from soil and stream sediment sampling programs. Approximately 10-12 drilling lines are designed to cover the anomalies, with drill holes angled -60 degrees toward the west, near perpendicular to the structural controls of the dominant faulted contact between the Euro Basalt and the Dalton Suite ultramafics. Drill depths will range from approximately 50-120m.

Western Australia based DDSR Australia Pty Ltd has been contracted to complete the RC drilling program. The 3,000m program is anticipated to take 4 to 6 weeks, with samples being freighted to Bureau Veritas laboratory in Adelaide SA for analysis.

Next Steps

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.
