23 Holes Drilled at Rabbit Trap with Weathered Ultramafic Rocks Found

Exploration Progress at Rabbit Trap

Rimfire Pacific Mining has announced the completion of a significant air core drilling program at its 100% owned Rabbit Trap Scandium Project, situated about 50 kilometres north of Fifield in central New South Wales. The campaign comprised 23 holes totalling 1,360 metres, focused primarily on the Malamute Scandium Prospect and three nearby magnetic anomalies believed to be prospective for scandium mineralisation.

The drilling successfully intersected weathered ultramafic pyroxenite rock at Malamute, a lithology consistent with previous scandium-bearing intercepts from earlier campaigns. This finding is encouraging as it suggests continuity of the scandium mineralisation within this zone, which spans approximately 400 by 500 metres and remains open laterally.

Challenges and Anomalies

While the Malamute Prospect drilling yielded promising geological indications, the team encountered difficulties with two of the three additional magnetic anomalies located to the northeast. Thick gravel layers, running sands, and abundant groundwater prevented the drill from reaching basement rocks at these sites, leaving their mineral potential uncertain. The third anomaly was penetrated, revealing deeply weathered possible sedimentary rocks, though their significance awaits confirmation through assay results.

These challenges highlight the complex geology and surface conditions at Rabbit Trap, suggesting that alternative drilling methods, such as diamond drilling, might be necessary to fully evaluate these targets in the future.

Next Steps and Market Implications

Samples from the recent drilling are currently being logged and prepared for dispatch to ALS Pty Ltd’s laboratory in Orange, NSW, with assay results anticipated by late January 2026. These results will be pivotal in determining the economic viability of the mineralisation encountered and underpinning a maiden mineral resource estimate for the Malamute Prospect.

Meanwhile, the air core rig has been relocated to Rimfire’s Murga Exploration Target at Fifield to continue exploration activities, reflecting the company’s ongoing commitment to advancing its critical minerals portfolio.

Rimfire’s Managing Director David Hutton expressed cautious optimism, noting the encouraging geological signs at Malamute and the potential for further discoveries pending assay confirmation. The company’s methodical approach and transparent reporting position it well to capitalize on the growing demand for scandium, a metal critical to emerging technologies.
