Official assays remain pending

Great Boulder Resources Ltd (ASX:GBR) has intersected extensive sulphide mineralisation in its first holes at the Eastern Mafic complex within the Mt Venn Project in Western Australia.

Importantly, this drilling has confirmed that bedrock sulphides are the source of electromagnetic (EM) conductors at the Eastern Mafic complex.

A total of 15 reverse circulation (RC), diamond and RC pre-collars have been drilled to date, with significant zones of sulphide mineralisation intersected at anomalies ML5, 9, 12, 15, and 16.

Supports theory Eastern Mafic is part of larger system

Mineralisation is pyrrhotite dominant with pyrite, chalcopyrite (copper sulphide) and pentlandite (nickel sulphide).

Pentlandite mineralisation supports Great Boulder’s view that the Eastern Mafic is a more nickel-rich part of the larger Mt Venn system.

Assays of wide zones of massive sulphides pending

Drilling has intersected wide zones of massive sulphide mineralisation within the core of the intrusion and along interpreted feeder structures.

Notably, mineralisation was intersected over five kilometre in strike length, confirming the Eastern Mafic is a substantial magmatic sulphide system.

Drill rigs to move to Mt Venn, then back to Eastern Mafic

Great Boulder will shortly move the diamond and RC drill rigs back to Mt Venn while assays are pending and the downhole EM survey is completed to better define the conductor plates.

Once assay and downhole EM results are received, drilling will resume at the Eastern Mafic complex.
