Metal Hawk (MHK) has unveiled fresh results from reverse circulation (RC) drilling at the Torana prospect within its Berehaven project in WA.
The Torana prospect lies 1.5 kilometres north and along strike of the Commodore nickel sulphide discovery within the project area.
Metal Hawk said since discovering the Commodore prospect in September last year, it had focused on exploring the nickel and gold mineralised system through drilling in the area which had so far yielded “significant” results.
However, the company has also continued regional exploration across the broader Berehaven project. Recent RC drilling at Torana has intersected a zone of “strong” nickel-copper-platinum group element (PGE) geochemistry.
One hole in particular returned a result of 10 metres at 0.2 per cent nickel, 424 parts per million (ppm) copper and 126 parts per billion (ppb) PGE from a 25-metre depth.
Drilling beneath this zone intersected a thick interval of weathered ultramafic rocks with highly anomalous nickel-copper-PGE geochemistry.
A separate drill hole intersected 35 metres at 0.26 per cent nickel, 132 ppm copper and 45 ppb PGE from 120 metres including 10 metres at 0.32 per cent nickel, 240 ppm copper and 87 ppb PGE.
Furthermore, a hole drilled 60 metres north intersected the same anomalous zone and returned a result of 40 metres at 0.42 per cent nickel, 234 ppm copper and 104 ppb PGE from 100 metres including 12 metres at 0.51 per cent nickel, 605 ppm copper and 236 ppb PGE from 101 metres.
Metal Hawk said it believed these results indicated a likely magmatic nickel sulphide source.
“We are very excited by the width of ultramafic rocks and the signature of strong nickel-copper-PGE anomalism in the latest batch of results and look forward to drilling the fresh rock below and more of these exciting regional prospects which historically have been very sparsely explored for nickel,” Managing Director Will Belbin said.
Furthermore, drilling to the south of the Commodore discovery intersected thicknesses of ultramafic rocks at downhole depths exceeding 100 metres. The majority of assays are pending and expected in the next four weeks.
Lastly, survey work identified a new late-time electromagnetic conductor at Berehaven East, and it’s considered a priority regional nickel sulphide target to be drill-tested.
The company will now undertake follow-up RC drilling to test the bedrock for nickel sulphide mineralisation beneath the weathered zone of nickel-copper-PGE anomalism.
MHK will also carry out downhole electromagnetic (DHEM) surveys to test for any conductive responses related to massive nickel sulphide mineralisation.
