"...Great Boulder completed a 226-hole aircore drilling program over the Eastern Mafic complex to map bedrock geochemistry and determine areas of elevated copper, nickel and cobalt. End of hole samples have been submitted for multi-element laboratory analysis, however Great Boulder routinely checked end of hole and 4m downhole composites with a portable XRF to provide live geochemical data.

Where aircore drilling crosses or is in close proximity to a conductor, there is a strong correlation between elevated copper-nickel values and the conductor. Aircore geochemistry used in conjunction with airborne and ground EM has worked exceptionally well at Mt Venn in discovering copper-nickel sulphide mineralisation...."
