Great Boulder Resources has advised the drilling at the Eastern Mafic complex has intersected additional copper, nickel and sulphide mineralisation.
It has also identified several new bedrock conductors using a down-hole survey. The survey was a co-funded program which was designed to test potential feeder structures which are believed to have higher nickel and deposits.
Drilling at the Zermatt and Cortina prospects identified new zones of sulphide mineralisation and associated off-hole conductor plates.
A total of seven drill holes were completed for a total drill depth of 2,117 metres.
There were also drills to target the dense core based on a gravity survey model. All of the holes intersected and ended with a significant amount of granite rather than then modelled denser magic-ultramafic units expected.
Notable discoveries include 0.5 per cent copper at 3.1 metres and 0.3 per cent nickel at 85 metres.
Survey results identified several off-hole conductors that will require additional drilling but is yet to be determined when. The additional drilling is also to test the conductor plates and determine the size and grade of any new mineralisation.
