Rimfire Pacific Mining advised 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. 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 east- dipping 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.

The targets are characterised by discrete magnetic features and /or anomalous surface geochemistry potentially indicative of buried nickel ­ cobalt ­ scandium mineralised mafic /ultramafic intrusive. The drilling will specifically determine depth to basement, the nature of any regolith (laterite) profile, underlying rock type, and source of the magnetic responses. The drilling program including receipt of assay results will take approximately two months to complete with Rimfire to provide further updates as and when new information comes to hand.
