THE DRILL SERGEANT: Sheffield Resources (ASX: SFX) has identified of three new nickel-copper-cobalt anomalies while conducting a program of regional aircore drilling at the company’s Red Bull nickel-copper project in July this year.
The Red Bull project is located 20 kilometres south of the Nova/Bollinger nickel-copper deposit of Sirius Resources (ASX: SIR), in the Fraser Range region of Western Australia.
The three anomalies have been named the Earlobe, Stud and Sleeper prospects and are collectively known by Sheffield as the ‘Northern Targets’.

All three targets occur within an 8km strike length of a layered mafic-ultramafic complex in the northern part of the Red Bull project.
The company indicated the anomalies remain open, with 3km of prospective strike yet to be tested by aircore drilling.
Results from each prospect include:
– 22 metres at 0.26 per cent nickel, 121ppm copper, 223ppm cobalt, 7.5ppb platinum from 32 metres, including 8 metres at 0.41 per cent nickel, 170ppm copper, 350ppm cobalt, 6.8ppb platinum from 32 metres;
– 12m at 0.32 per cent nickel, 204ppm copper, 337ppm cobalt, 8 ppb palladium from 37m; and
– 8m at 0.15 per cent nickel, 400ppm copper, 261ppm cobalt, 14.5ppb palladium, 14.5ppb platinum from 22m;
– 6m at 0.24 per cent nickel, 53ppm copper, 170ppm cobalt, from 52m.
– 4m at 0.16 per cent nickel, 203ppm copper, 301ppm cobalt from 44m.
“These results are highly encouraging and demonstrate the potential for significant nickel-copper mineralisation at Red Bull,” Sheffield Resources managing director Bruce McQuitty said in the company’s announcement to the Australian Securities Exchange.
“We have identified a discrete, eight kilometre long unit within a mafic-ultramafic complex, which displays strong nickel, copper and cobalt anomalism.
“Elevated palladium and platinum values are a further indication that we are in the right setting for a magmatic nickel sulphide system.
“The tenor of anomalism is similar to that found in the halos to nickel deposits.
“The next phase of work will include an examination of disseminated sulphides observed in end-of-hole samples to determine if they are of magmatic origin.”
