Rimfire Pacific Mining (ASX: RIM, 'Rimfire' or the 'Company') advises that a 3,000-metre drilling program to test for primary platinum + palladium (PGE's) mineralisation within un-weathered (fresh) ultramafic bedrock has commenced at its Avondale and Fifield Projects, which are located 70 kilometres northwest of Parkes within the highly prospective Lachlan Orogen of central
Commenting on the announcement, Rimfire's Managing Director Mr

Drilling Details
15 Diamond holes (3,000 metres) will be drilled to test for primary platinum + palladium (PGE's) mineralisation at 6 targets (Melrose, Jack's Lookout, Gillenbine, Platina Lead,
The targets are prospective for the discovery of ultramafic - hosted PGE's, nickel, cobalt, scandium, and copper mineralisation and are characterised variously as having historic surface anomalism and / or historic drill intercepts (Currajong, Platina Lead, and Gillenbine), or a poorly tested magnetic anomaly interpreted to represent prospective ultramafic rock types (Melrose, Jacks Lookout and
Drilling at Jack's Lookout and Gillenbine aims to confirm the presence of primary PGE mineralisation within the underlying ultramafic units. Several drillholes will also test directlybeneath surface workings at Platina Lead to determine the prospectivity of an interpreted ultramafic unit that may be the source of the shallow alluvial mineralisation.
At Melrose, recent wide spaced aircore drilling of a 'bullseye' magnetic anomaly by Rimfire successfully confirmed the presence of an ultramafic intrusive unit, assaying of which returned strongly anomalous levels of nickel, cobalt, scandium, and copper from several holes.
Subsequent re-assaying of 8 composite aircore samples has returned anomalous PGE's up to 0.31g/t platinum + palladium which suggests that the Melrose ultramafic is potentially platiniferous. The current deep drilling will be the first test of the ultramafic beneath the base of weathering and aims to confirm whether the unit is prospective for primary PGE mineralisation.
