Rimfire Pacific Mining (ASX:RIM) has tripled its mineral resource estimate at the Murga Scandium Deposit, 70km northwest of Parkes in Central New South Wales.
Rimfire has appointed H&S Consultants to update the mineral resource estimate. H&S found the latest estimate was 300% higher than previously thought.
The amount increased after factoring in new drilling on 100 metre x 100 metre spacings at open scandium mineralised zones. If drilling uncovers strikes this will add “further tonnes” of scandium mineralisation resources.
Further infill drilling on 50 metre x 50 metre spacings could locate and show continuous higher-grade scandium. The company believes that this might increase the grade and add further tonnes of scandium mineralisation to the resource.
The Malamute prospect at Rimfire’s fully owned Rabbit Trap Scandium Project (40km north of Murga) and other locations offer further scandium prospects for more resources.
Rimfire now seeks regulatory approval for follow-up drilling at Murga, to finalise specialist laboratory quotes for metallurgical test work under the guidance of Boyd Willis of Hydromet Consulting.
“Quantifying such a large and geologically variable greenfields area such as Murga is never a linear process, and the technical insights we have gained from this latest work has improved our understanding of internal grade variability and orientation and will optimise our next round of extensional and infill drilling,” Managing Director David Hutton says.
“We are confident that further drilling success at Murga and our Malamute Scandium Prospect at Rabbit Trap will substantially grow the resource inventory.”
Drilling is expected to begin during the June 2026 quarter, depending on regulatory approval and suitable drilling contractor availability.
Rimfire Pacific Mining is a critical minerals exploration company with assets mainly in New South Wales and South Australia.
