The PlatSearch Board is pleased to
announce that joint venture partner Bondi Mining Limited "Bondi" (ASX Code:
BOM) has received assays for a rock chip sampling programme conducted within
the Cymbric Vale joint venture project area in western New South Wales. The
directors of Bondi have advised PlatSearch that the results have confirmed
the area is prospective for copper and nickel sulphide related
mineralisation and follow-up programmes of geophysics and drilling will
commence shortly.
Rock chip samples collected from a number of
prospects across the Cymbric Vale Project area have returned encouraging
results.
Cymbric Vale Copper prospect extends over 1.2
kilometres of strike length returning grades of up to 5.61% and 4.91%
copper and has never been drill tested.
Sampling has confirmed the presence of ultramafic
rocks at the Horseshoe Hills prospect with anomalous nickel assays to
2,200ppm (0.22%) and cobalt up to 4,250ppm (0.43%).
Programmes of geophysics (EM) and drilling will
commence next quarter.
The Cymbric Vale Project is located in
the Koonenberry Belt on the eastern margin of the Curnamona Craton,
approximately 120 kilometres northeast of Broken Hill. The Koonenberry Belt
extends for at least 200 kilometres and is characterised by multiple, deep
crustal, dip-slip fault structures with subsidiary splays and cross
structures. A number of ultramafic intrusives occur in the region (such as
at Mt Wright and Cymbric Vale) suggesting that these faults are
mantle-tapping structures - favourable indications for the occurrence of
sulphide nickel deposits. Major nickel companies are currently exploring
large parts of the Koonenberry Belt for nickel. Black Range Minerals, on an
adjoining licence, have announced a JORC-compliant Resource at the
Koonenberry Base Metal Project of 5.75 million tonnes at 1.03% copper, 0.35%
zinc, 2.30 g/t silver and 0.05 g/t gold containing approximately 60,000
tonnes of copper. (NB)
Rock chip sampling and reconnaissance
mapping was carried out on four prospective areas and a brief summary of
results follows.
At the Cymbric Vale Copper prospect
historical pits and shafts have accessed secondary copper mineralisation
that occurs sporadically within ferruginous schists and gossanous outcrops
over 1.2 kilometres of strike length. Recent rock chip sampling by Bondi
returned high-grade copper up to 5.61% and 4.91% and anomalous gold
to 0.11 g/t. Gossan surface expression is limited and economic
concentrations of sulphides may occur in structurally thickened zones along
strike and at depth. To the south a number of prospecting pits and a
relatively deep shaft have accessed sulphide-bearing material. The joint
venture intends to conduct ground EM to further refine drill targets at the
prospect.
At Black Hills within the
centre of the licence, the joint venture is targeting a large aeromagnetic
anomaly for potential nickel sulphide mineralisation. Numerous historical
workings have been sunk on ferruginous ironstone at the margins of what may
be an ultramafic body concealed by younger (Mesozoic) sediments and seen in
results of a completed ground magnetic survey. Sampling of the surrounding
ironstone outcrops have returned up to 1,850ppm (0.19%) copper. The joint
venture intends to drill test the anomaly.
The Horseshoe Hills and
Baroorangee Creek prospects are two ends of a larger, covered magnetic
anomaly that is co-incident with outcropping ultramafic rocks. Sampling
returned nickel values up to 2,200ppm (0.22%) confirming the presence of
ultramafic rocks. The area is considered prospective for ultramafic related
nickel, copper and platinum group elements. Drill testing of thicker
portions of the ultramafic body is planned.
The Rawlins Tank prospect
occurs as an east-west striking ridgeline covering
an area of approximately two square kilometres containing numerous quartz
veins and related silicification adjacent to regional-scale fault
structures. Rock chip sampling returned up to 4.96% copper and 0.13
g/t gold. It is intended to drill test this prospect.
PlatSearch considers that results of
exploration to date offer significant encouragement in regard to possible
discovery of sulphide nickel deposits, structurally emplaced and stratiform
copper gold deposits. Reconnaissance mapping and the results of rock chip
sampling indicate that there are prospective ultramafic rocks present.
Furthermore, the geology of the Cymbric Vale prospect is similar to the
nearby Koonenberry Base Metal project, located 12 kilometres to the east.
