PepinNini Minerals (ASX:PNN) and joint venture partner Rio Tinto (ASX:RIO) have intersected massive to semi-massive sulphides from drilling at the Marrawah Prospect in the Musgrave region of South Australia.
Drill core samples returned copper values up to 2500 ppm (0.25%).
The JV was searching for magmatic nickel-copper sulphide deposits across the Musgrave Province in far north South Australia, within the Caroline Intrusion.
Two cored boreholes have been completed, drilled to test a priority fixed loop electromagnetic conductivity anomaly.
Intercepts observed included 32 metres with disseminated to massive sulphides from 77 metres, and a 10.9 metre zone of massive to semi-massive sulphides from 88.1 metres.
Analytical results across from core samples returned maximum values of 2,500 parts per million copper, 745 parts per million nickel, 660 parts per million cobalt, 13 parts per billion gold, 3.5 parts per billion platinum and 6 parts per billion palladium.
Sulphide phases present in drill cores consist of abundant pyrrhotite (iron sulphide) with lesser chalcopyrite (copper sulphide) and are hosted within sulphidic pyroxenite and sulphidic gabbronorite.
PepinNini is earning up to 51% of the project.
Additionally, PepinNini has confirmed a joint research and development project with CSIRO for platinum group metals within the Caroline Intrusion.
All metreages quoted are downhole depths and true widths are not as yet known.
