Rimfire Pacific Mining (ASX: $RIM) First Pass Leach Test Work Update

Rimfire Pacific Mining (ASX: $RIM) has reported positive results from the first pass sighter leach test work conducted on mineralised laterite material from the Melrose Scandium Cobalt Nickel Prospect in central NSW. The test work focused on producing a combined product from Melrose laterite-hosted mineralisation, returning recoveries of up to 40% scandium, 90% cobalt, and 58% nickel at atmospheric pressures. The upcoming metallurgical testing will aim to maximize scandium recovery and optimize energy requirements and reagent consumption. Additionally, a 2,000m RC/Diamond drill program is set to commence in the next 2 weeks to underpin the estimate of a maiden JORC Mineral Resource Estimate (MRE) for Melrose, fully funded by Rimfire's exploration partner - GPR.

Executive Commentary on First Pass Leach Test Work

Rimfire's Managing Director, Mr David Hutton, expressed optimism, stating, 'The results of the first pass sighter leach test work are highly encouraging and pave the way for ongoing metallurgical and geological studies at Melrose. With further test work and JORC Resource drilling due to start in the next 2 weeks, Melrose is quickly shaping up nicely as a significant critical minerals opportunity for Rimfire and its shareholders.'

Summary of First Pass Leach Test Work and Outlook

The first pass leach test work at Melrose has demonstrated the potential for increased metal recoveries, especially for scandium, cobalt, and nickel. The upcoming metallurgical testing and drill program aim to further enhance recoveries and underpin the maiden JORC Mineral Resource Estimate. The positive results align with the growing market interest in Australian scandium projects, indicating significant opportunities for Rimfire in the critical minerals sector. With the potential for enhanced project economics, Rimfire's strategic focus on atmospheric pressure leaching process route and ongoing studies position Melrose as a promising development opportunity. The company's activities are fully funded by its exploration partner, and the outlook for Melrose appears promising, reflecting Rimfire's commitment to maximizing recovery grades and commercializing critical mineral extraction.
