Ardea to unleash drill rig in WA nickel sulphide hunt | Ralph-Lauren

Must Read


Ardea Resources is set to get the drill rods spinning in its nickel sulphide hunt at its Kalpini project 70 kilometres north-east of Kalgoorlie in Western Australia. At the Emu Lakes prospect, one hole will test a new geophysical target coinciding with a recent drilling intercept that returned 1.1 metre at 4.78 per cent nickel. A second hole will target a new geophysical anomaly at the Wellington East C prospect.

The 100 per cent owned Kalpini project covers more than 240 square kilometres of tenure and plays host to two ultramafic belts prospective for high-grade and disseminated nickel sulphide mineralisation. Each belt reportedly takes in more 20km of strike.

Ardea’s recent drill hole at Emu Lake, AELD0002, along the ‘western’ ultramafic belt delivered the 1.1m hit going 4.78 per cent nickel, 0.16 per cent copper, 0.47 grams per tonne platinum and 0.2 g/t palladium from 366.9m.

The highly encouraging intercept fell within a broader 4.8m interval going 1.44 per cent nickel, 0.09 per cent copper, 0.2 g/t platinum and 0.09 g/t palladium from 365.9m.

The hit represents one of the best nickel sulphide intercepts historically drilled at Emu Lake, according to Ardea.

Two recent geophysical surveys near the hole have now identified the new nickel sulphide target.

The target stretches for 80m of strike and extends to within 150m of surface and is open at depth, according to the company. Drilling will look to intersect the target at about 210m down hole with the rods set to start turning in the coming days.

Ardea drillhole, AELD0002, intersected high grade nickel sulphide mineralisation hosted within an ultramafic unit located on an intact felsic footwall contact, so we have confirmed the required geology and nickel sulphide fertility. Follow-up geophysical surveys have indicated that this zone of nickel sulphide extends up and down plunge from AELD0002.

The next stage of exploration on this target is to drill a reverse circulation hole to test the interpreted up-plunge extension of the nickel sulphide mineralisation. If successful, Ardea will have confirmed a nickel sulphide discovery, at our Emu Lake prospect, located only 70km northeast of the City of Kalgoorlie-Boulder.

Curiously, Poseidon Nickel’s Black Swan operation sits within a komatiite volcanic belt running parallel to Kalpini, some 35km away.

The Black Swan tenure hosts the historical Black Swan and Silver Swan nickel sulphide mines which together produced a whopping 178,500 tonnes of nickel in concentrate.

Poseidon is also dishing out eye-catching nickel sulphide hits at the Golden Swan discovery below the old Black Swan mine. Intercepts include 9m at 10.46 per cent nickel and 6.4m at 9.6 per cent nickel.

Poseidon is targeting to re-commence production in 2022.

Ardea is also planning to drill a second hole at the Wellington East C target, immediately west of the ‘eastern’ ultramafic belt at Kalpini.

Drilling will look to intercept a newly defined target identified via a moving loop electro-magnetic survey. The target is reported to lie beneath a strong copper anomaly.

Ardea reports that historical drilling some 80m along strike from the proposed hole returned anomalous copper mineralisation grading as high as 1,370 parts per million copper.

The mineralisation is reported to be strong toward the bottom of the holes suggesting a primary source of sulphide mineralisation could be nearby, according to Ardea.

The company’s nickel hunt appears to be immaculately timed as the metal continues to trade close to multi-year highs. With the price of copper also stretching skyward, the Perth based company will no doubt be holding its breath awaiting results from its drill holes at Kalpini.
