Cullen Resources (ASX: CUL) has encountered nickel sulphides from RC drilling at its Wongan Hills Project north-east of Perth, in a result described as delivering ‘significant’ prospectivity for Ni-Cu-PGE mineralisation.
The sulphides come from the previously-reported hole RC6 at the project’s Rupert Prospect, with examination work carried out by independent petrologists investigating a ‘strongly anomalous’ section 30m down hole.
“The discovery implies significant prospectivity for Ni-Cu-PGE mineralisation along a substantial, and underexplored, 15km magnetic-stratigraphic trend”
Results returned nickel sulphides and/or iron + copper sulphides from six drill chips, including pentlandite, pyrite, pyrrhotite, bravoite, and violarite, hosted in a structure which remains open up and down-dip, and in both directions along strike.
Hole RC6 was tasked with testing a ground electromagnetic anomaly located approximately 125m downhole, with a 2m semi-massive to massive sulphidic banded-iron formation found to be the source of the target.

Cullen reports that it will re-assay RC6 core samples in search of platinum group elements.
The company will also undertake first-pass exploration that may include auger drilling, EM survey and aircore drilling, scheduled between December 2021 to April 2022 to work in with seasonal wheat farming activity surrounding the prospect.
Commenting on the results, Cullen Resources Managing Director Chris Ringrose said: “The occurrence of nickel sulphides in ultramafics within E4882 at Wongan Hills is a discovery that implies significant prospectivity for Ni-Cu-PGE mineralisation along a substantial, and underexplored, 15km magnetic-stratigraphic trend which is a new focus for exploration.”
