Thor Mining Plc (AIM, ASX: THR) has identified a conductive anomaly through the recently completed electromagnetic geophysics survey over the nickel gossan at the Krona Prospect at the company’s 100% owned Ragged Range Project, located in the Eastern Pilbara, Western Australia.
Project highlights:
- A high-powered Fixed Loop Electromagnetics (FLEM) ground geophysics survey has identified a shallow conductor beneath the nickel gossan at the Krona Prospect
- The conductor is consistent with sulphides and warrants drill testing to validate.
- The nickel gossan is located at the basal contact of the Dalton Suite ultramafic unit (altered Archean Komatiite) in the classic location for nickel-copper sulphide mineralisation.
- The shallow conductor will be drill tested including downhole EM, as part of the upcoming reverse circulation (RC) drilling programme scheduled to commence next week at the Sterling Gold Prospect
I am encouraged that the first ground geophysics survey at Ragged Range has identified a shallow electromagnetic conductor,” Managing Director, Nicole Galloway Warland, said.
“The target is modelled at around 100m below the surface, establishing it a clear drill target for the upcoming RC drilling programme.
“We look forward to drill testing this anomaly as part of our RC drilling program, scheduled to commence at Sterling Prospect next week.”
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.
Krona Prospect – Nickel Gossan
A high-powered Fixed Loop Electromagnetics (FLEM) ground geophysics survey was completed over the Krona Prospect, covering the full extent of the nickel gossan, located in the western portion of the tenure.
This is the first ground geophysics survey on the Ragged Range Project. The survey over the gossan was designed to detect conductive anomalies at depth that may indicate the presence of massive nickel-copper sulphide mineralisation to constrain initial drill testing.
A single loop FLEM survey over the Krona prospect identified a conductor at the southern end of the gossan.
The conductor was modelled as a shallow flat lying feature approximately 100m deep and is consistent with sulphides. The shallow (100m) conductor gives Thor a clear drill target, that will be drill tested as part of the upcoming RC program at the adjacent Sterling Prospect.
The gossan was initially identified by the Western Australian Geological Survey on the Split Rock 1:100K mapping explanatory notes.
The gossan extends over 1km x 100m and lies on the basal contact of the Dalton Suite ultramafics, with the older Wyman Formation, felsic volcanics.
Next Steps
- Commence RC drilling programme at Sterling Prospect following up on structurally controlled anomalous gold in streams and soils.
- Drill test EM conductor at Krona Prospect as part of RC drilling program, with downhole EM.
- An Airborne magnetic/radiometric survey, scheduled to be flown over the eastern portion of the tenure (including E46/1340 and E46/1393) in the near future.
- Continue regional exploration, focusing on both lithium priority areas and the copper-gold historic workings in the north-eastern portion of tenure.
