An update from Rimfire Pacific Mining Limited ( (AU:RIM) ) is now available.

Rimfire Pacific Mining has launched a metallurgical study on low iron scandium mineralised material from its Murga deposit in the Fifield District, aiming to determine if the metal can be economically recovered at atmospheric pressure. Initial bottle roll leach tests are underway on representative core samples, with findings expected by late June 2026 and potential follow-up work using agitated or vat leach techniques.

Murga now hosts an inferred resource of 56.1Mt at 138ppm scandium for 11.9kt of scandium oxide, contributing to Rimfire’s total scandium oxide resource of more than 16kt. The deposit’s relatively low iron content could allow the use of less capital-intensive atmospheric tank or vat leaching instead of high pressure acid leaching, a potential technical and economic advantage that may enhance project economics and support Rimfire’s ambition to build a globally significant scandium inventory at Fifield.
