PepinNini Minerals (ASX: PNN) has intersected massive to semi-massive sulphides at the Byron Prospect, which is part of the Musgrave project in South Australia.
Highlights include:
- 47 metres with matrix and disseminated sulphides from a depth of 127metres;
- 15 metre zone with intervals of massive to semi-massive sulphides from a depth of 196 metres, followed by 28 metres with matrix and disseminated sulphides from a depth of 248 metres; and
- 20 metres with matrix and breccia sulphides from a depth of 167 metres, followed by 4 metres of matrix sulphides from a depth of 207 metres.
Sulphide phases present in drill cores consist of abundant pyrrhotite (iron sulphide) with lesser pyrite (iron sulphide) - chalcopyrite (copper sulphide) - molybdenite (molybdenum sulphide) and are hosted within a garnet-pyroxene mafic granulite as well as brecciated garnet-bearing orthogneiss.
Assay results from three cored holes drilled at the Byron prospect have been received and include concentrations of up to 0.17 g/t gold, 934ppm copper, 862ppm nickel and 52ppm molybdenum.
The intersections follow on from a ground EM survey to extend SkyTEM508 conductors.
First pass follow up drilling of SkyTEM508 electromagnetic anomalies has been completed at Cooperinna as part of PepinNini’s ongoing search for magmatic Nickel-Copper sulphide deposits across the Musgrave Province,
Similarities to BHP’s Nebo-Babel / Sirius' Nova
Where the story comes even more interesting for PepinNini is that petrological investigation of drill core samples has concluded that mafic host rocks show mineralogical similarities to Giles Complex igneous intrusions like those that host Ni-Cu-PGE mineralisation at BHP Billiton’s (ASX: BHP) Nebo-Babel deposit in the Western Musgrave Province.
Garnet-pyroxene granulites incorporated within the zones of sulphide mineralisation are also analogous in age and mineralogy to rocks that host Sirius Resources' (ASX: SIR) "Nova" Nickel-Copper Sulphide deposit within the Albany-Fraser region of Western Australia.
