Rimfire to Drill 85 Holes at Murga, Targeting 4,200m for Resource Estimate

Strategic Drilling Initiative at Murga

Rimfire Pacific Mining has announced the imminent commencement of an infill air core drilling program at its Murga Exploration Target in New South Wales’ Fifield district, a region rapidly gaining attention as Australia’s scandium hotspot. The program, comprising approximately 85 holes totaling 4,200 metres, is scheduled to begin in mid-November 2025 and aims to underpin a maiden mineral resource estimate by the March 2026 quarter.

Murga lies just four kilometres south of Sunrise Energy Metals’ Syerston Scandium Deposit, a project that has recently attracted significant investor interest. Rimfire highlights geological parallels between Murga and Syerston, particularly the presence of scandium-bearing pyroxenite intrusive rocks overlain by weathered laterite horizons. These similarities bolster confidence that Murga could contribute meaningfully to Rimfire’s scandium resource base.

Funding and Operational Control

Originally part of a joint venture with Golden Plains Resources, the Murga drilling program is now fully funded and controlled by Rimfire after its partner elected not to support the work. Rimfire exercised its voting majority to proceed, underscoring the company’s conviction in Murga’s potential as the most promising commercial development opportunity within the Fifield Project.

The drilling will infill existing broad-spaced holes to achieve a nominal 100-metre spacing, focusing on the northern and central portions of the Murga target area. This approach is designed to convert the current exploration target, which remains conceptual and uncertain, into a defined mineral resource compliant with JORC standards.

Resource Growth Potential and Next Steps

Successful conversion of the Murga Exploration Target could significantly increase Rimfire’s scandium inventory at Fifield, which currently stands at 5,449 tonnes of scandium metal (equivalent to 8,333 tonnes of scandium oxide). This would complement existing resources at Melrose, Murga North, and Currajong deposits, consolidating Rimfire’s position as a leading scandium explorer in Australia.

Following the Murga drilling campaign, Rimfire plans to deploy its rig to the 100%-owned Rabbit Trap Scandium Project, continuing its systematic exploration strategy across the region. The company has secured all necessary regulatory and landowner approvals, with drilling expected to take approximately three weeks. Assay results will be submitted progressively, enabling a timely mineral resource estimate in early 2026.

Market Context and Outlook

Scandium remains a critical metal with growing demand driven by its applications in aerospace, fuel cells, and aluminium alloys. Rimfire’s focused drilling at Murga aligns with broader market trends seeking to secure reliable scandium supplies. The proximity to Sunrise Energy Metals’ Syerston deposit also places Rimfire in a strategic position to capitalize on regional exploration momentum.

While the exploration target at Murga is still conceptual, Rimfire’s proactive funding and drilling commitment signal confidence in the district’s potential. Investors will be watching closely for assay results and the subsequent resource upgrade, which could reshape the company’s valuation and influence scandium sector dynamics in Australia.
