Slide 8: Eastern Mafic: Maiden drilling program
Eastern Mafic Maiden drilling program ▪ First drill holes into the Eastern Mafic intersected For personal use only extensive mineralisation ▪ The best results to date come from the feeder structure and ‘neck’ of the intrusion ▪ Significant results include: − 33m at 0.3% Ni, 0.2% Cu, 0.04% Co − 5m at
Slide 9: Eastern Mafic: Unlocking higher grade nickel
Eastern Mafic Unlocking higher grade nickel ▪ For personal use only Three distinct sulphide phases have been identified at the Eastern Mafic, with high-tenor nickel sulphide found along the feeder zone and neck of the intrusion ▪ This supports Great Boulder’s view that the Eastern Mafic is closer to
Slide 10: Mt Venn Discovery
