Rimfire Pacific Mining (ASX: RIM, 'Rimfire' or 'the Company') is pleased to advise that an aircore drilling program of 2,000 metres designed to determine the extent of nickel - cobalt - scandium mineralisation at the Melrose prospect and to test the geological significance of several new targets is underway on its Avondale and Fifield Earn In Projects which are located 70 kilometres northwest of Parkes within the highly prospective Lachlan Orogen of central New South Wales.

Parkes is the site of the New South Wales Government's proposed Critical Minerals Hub which will be central point for mining and value added processing of critical minerals within the state (source - NSW Government - critical minerals and high tech metals website). Commenting on the announcement, Rimfire's Managing Director Mr David Hutton said: 'Rimfire remains focussed on exploring for and developing critical minerals opportunities within NSW's Lachlan Orogen. The latest phase of drilling builds on our previous success at Melrose and assists with building a strong pipeline of priority drill targets which will underpin future work programs

Drilling program details

Rimfire is undertaking aircore drilling (2,000 metre program) to determine the extent of the known nickel - cobalt - scandium mineralisation at the Melrose prospect as well as testing the significance of several new targets on the Avondale and Fifield Earn In Projects. At Melrose, nickel - cobalt - scandium (Ni - Co - Sc) mineralisation occurs at shallow depths within a flat - lying manganese and iron rich (laterite) zone, which is developed over an eastdipping sequence of interlayered ultramafic rocks (pyroxenite, wehrlite, and serpentinised dunite) that is fault bounded against a gabbro to east and volcaniclastic sediments to the west.

Aircore and diamond drilling undertaken last year by Rimfire returned multiple strongly anomalous drill intercepts, e.g.; 21m @ 0.11% Ni, 0.07% Co, and 529 Sc, from 3 metres in FI2397 including 9m @ 0.17% Ni, 0.15% Co and 688ppm Sc from 14 metres, 2.3m @ 0.15% Ni, 0.08% Co and 461ppm Sc from 3 metres and 5.0m @ 0.68% Ni, 0.07% Co and 302ppm Sc from 16 metres in FI2398, 4.9m @ 0.36% Ni, 0.11% Co and 349ppm Sc from 5 metres, and 4.3m @ 0.42% Ni, 0.09% Co and 296ppm Sc from 10.1 metres in FI2399, 10.0m @ 0.14% Ni, 0.10% Co and 456ppm Sc from 1 metre in FI2400 including 5m @ 0.17% Ni, 0.17% Co and 568ppm Sc from 5 metres,

Melrose remains open along strike both to the north and south and the current drilling will be undertaken on a north - south and sperate south east - north west orientated traverse to determine the extent of the mineralisation. As well as the Melrose drilling, Rimfire has recently engaged Perth specialist metallurgical services group - Independent Metallurgical Operations Pty Ltd (IMO) to develop a conceptual processing flowsheet with the aim of optimising atmospheric leach recoveries and production of a nickel - cobalt - scandium product from high-grade mineralised material from Melrose. Subject to a favourable outcome from both the current aircore drilling and the metallurgical test work, Rimfire will undertake a detailed drill out of the Melrose prospect with a view to estimating a maiden 2012 JORC Code compliant Mineral Resource Estimate (MRE) for the location. In addition to testing the extent of Melrose mineralisation, the aircore drilling will test the significance of several new targets (Glen Avon, Murga North, Murga South, Carlisle, and Forest View) which lie within a regional scale 50-kilometre-long belt of underexplored intermediate volcaniclastics, sediments and ultramafic intrusive units that make up a geologically significant regional - scale structure at Avondale called the 'Steeton Ultramafic Suture Zone'.

About Rimfire

Rimfire Pacific Mining (ASX: RIM, 'Rimfire' or the 'Company') is an ASX-listed Critical Minerals exploration company which is advancing a portfolio of projects within the highly prospective Lachlan Orogen and Broken Hill districts of New South Wales. The Company has two 100% - owned copper - gold prospective projects that are located west of Parkes and Orange in central New South Wales: The Valley Project - located 5km west of Kincora Copper's Mordialloc porphyry copper gold discovery (KCC.ASX), and The Cowal Project - located to the east of Evolution's Lake Cowal Copper / Gold mine (EVN: ASX). Rimfire also has the 100% - owned Broken Hill Cobalt (Green View) Project which is located immediately west and northwest of Broken Hill and covers several targets including the interpreted along strike extension to Cobalt Blue Holdings' Railway Cobalt Deposit (COB: ASX). Rimfire has two additional projects in the Lachlan Orogen which are being funded by Rimfire's exploration partner - Golden Plains Resources (GPR):
