Rimfire Pacific Mining Limited Announces Significant Ni, Co and Pt Drilling Results At Currajong
Rimfire Pacific Mining Limited advised that recent aircore drilling at the Currajong prospect has intersected significant anomalous nickel - cobalt mineralisation within the weathered portion of a platinum - mineralised ultramafic unit that can be mapped in magnetics for over 2.5 kilometres strike length. Currajong forms part of Rimfire's Avondale Project which is located 70 kilometres northwest of Parkes within the highly prospective Lachlan Orogen of central New South Wales. Sixty-three vertical aircore holes (FI2235 to FI2288 and FI2322 to FI2329 - 1,763 metres) were drilled by Rimfire on nominal 50 x 100 metre centres at the southern end of the ultramafic unit with strongly anomalous nickel (Ni) and cobalt (Co) returned from multiple drill holes. FI2285 - 34m at 0.29% Ni, 0.15% Co, and 101ppm Sc from 6 metres including 16m at 0.27% Ni, 0.22% Co, and 120ppm Sc from 8 metres, FI2261 - 28m at 0.53% Ni, 0.06% Co, and 41ppm Sc from 5 metres, including 5m at 0.57% Ni, 0.09% Co, and 56 Sc from 16 metres, FI2245 - 9m at 0.16% Ni, 0.14% Co, and 111ppm Sc from 18 metres, FI2248 - 20m at 0.30% Ni, 0.07% Co, and 54 ppm Sc from 9 metres, including 6m at 0.29% Ni, 0.10% Co, and 75ppm Sc from 13. FI2284 - 11m at 0.23% Ni, 0.05% Co, and 118ppm Sc from 8 metres, FI2278 - 13m at 0.30% Ni, 0.08% Co, and 34ppm Sc from 8 metres, FI2287 - 17m at 0.62% Ni, 0.04% Co, and 68 ppm Sc from 7 metres, and FI2257 - 4m at 0.57% Ni, 0.06% Co, and 74 ppm Sc from 20 metres. FI0903 - 20m at 0.18% Ni, 0.10% Co, and 78ppm Sc from 10 metres including 8m at 0.22% Ni, 0.14% Co, and 115 ppm Sc from 12 metres, FI0900 - 10m at 0.52% Ni, 0.05% Co, and 23ppm Sc from 18 metres including 2m at 0.83% Ni, 0.06% Co, and 45ppm Sc from 20 metres, and FI0904 - 24m at 0.18% Ni, 0.05% Co, 310ppm Sc from 20 metres. The nickel cobalt mineralisation occurs within a flat lying weathered zone that is developed over an ultramafic unit that can be "mapped" in magnetic imagery for over 2.5 kilometres. The recent drilling which was focused on the southern end of the ultramafic has now defined nickel - cobalt mineralisation (using a +200-ppm cobalt contour) over an approximate area of 800 metres x 200 metres. The ultramafic unit appears to be a "sill" like body and is made up of peridotite, serpentinite and pyroxenite lithologies and is bounded to the east and west by a mixed sequence of sediments, felsic intrusions, and minor ultramafic units. The ultramafic is platiniferous, with strongly anomalous platinum (Pt) +/- palladium (Pd) intersected in wide spaced shallow holes drilled in the late 1990's and early 2000's - none of which were followed up at the time. RC02A03 - 8m at 0.54g/t Pt +Pd from 24 metres, RC02A04 - 6mat 0.72g/t Pt + Pd from 26 metres and 20m at 0.80g/t Pt + Pd from 52 metres (Hole ended in mineralisation), RC02A05 - 44m at 0.34g/t Pt + Pd from 8 metres including 8m at 0.87g/t Pt + Pd from 10 metres including 2m at 1.34g/t Pt + Pd from 12 metres, RC02A06 - 2m at 0.58g/t Pt + Pd from 34 metres, AC03A08 - 27m at 0.33g/t Pt + Pd from 32 metres (Hole ended in mineralisation), AC03A17 - 4m at 0.61g/t Pt + Pd from 52 metres (Hole ended in mineralisation), AC03A23 - 5m at 0.39g/t Pt + Pd from 8 metres, AC03A25 - 5m at 0.46g/t Pt + Pd from 12 metres, AC03A27 - 4m at 0.58g/t Pt + Pd from 23 metres and 3m at 0.57g/t Pt + Pd from 29 metres, AC03A45 - 4m at 0.76g/t Pt + Pd from 8 metres. Significantly only 54 holes out of the total 204 holes drilled at Currajong (i.e., one quarter) have been analysed for platinum and palladium, and of those holes, only three (RC02A04, AC03A08, and AC03A17) tested the ultramafic below the base of weathering with each intersecting platinum + palladium mineralisation in the fresh ultramafic. As such the Currajong ultramafic (beneath the base of weathering) remains largely untested for platinum and palladium, and completely untested for all other Platinum Group Elements (PGE's) such as iridium, osmium, rhodium, and ruthenium.
