White Cliff hits two new mineralised zones
THE DRILL SERGEANT: White Cliff Minerals (ASX: WCN) has completed six diamond holes targeting conductive electromagnetic (EM) anomalies within an ultramafic rock sequence at the company’s Lake Johnston project in Western Australia.
White Cliff said it had intersected sulphide zones ranging in width from one metre to five metres in five of the six holes, which the company considers to explain the targeted electromagnetic conductors.
“The sulphide zones consist of pyrite and/or pyrrhotite with three holes containing minor visible sphalerite (zinc sulphide),” White Cliff Minerals said in its ASX announcement.
“No visible nickel sulphides were identified. The sulphide zones have been submitted for assay and results are expected over the next three weeks.”

White Cliff said the sixth hole drilled into the western ultramafic unit intersected two zones of silver at 34 and 76 metres respectively.
The upper zone contained:
– 2 metres at 71 grams per tonne silver with trace gold, copper and tungsten.
The lower zone contained:
– 1m at 144g/t silver, 0.1 per cent copper, 0.04g/t gold and traces of tungsten.
Both mineralised zones occurred on the contact between ultramafic and felsic porphyry rocks.
Silver and gold mineralisation was also identified at surface with 3m at 14.5g/t silver and 34ppb gold.
White Cliff said it now intends to carry out a soil geochemistry survey to establish the extent and intensity of the surface silver and gold anomaly to allow future drilling to be effectively targeted.
The drill program was partly funded by the Western Australian Government’s Royalty for Regions Exploration Incentive Scheme which will contribute $90,000 towards the drilling at Lake Percy.
White Cliff is currently undertaking an extensive geophysical survey to evaluate areas of the Lake Percy tenement not previously tested with geophysics.
To date the survey has identified six new conductors; two to the northwest of the current drilling program within the eastern ultramafic sequence and four in the southern corner of the tenement within the central ultramafic sequence.
Each conductive target sits on or adjacent to an ultramafic contact that White Cliff considers having the potential to host nickel sulphide mineralisation.
White Cliff was able to completed diamond drilling at the Lake Percy prospect, however drilling at the Mt Gordon site was deferred due to heavy rain limiting access to drill sites.
The Mt Gordon drilling program has been rescheduled for early 2013.
