Great Boulder Resources (ASX: GBR) has commenced an RC drilling to test a large nickel sulphide target at its Mt Carlon project in Western Australia.
Managing Director, Andrew Paterson, said the drilling is designed to test a 3.5km-long geophysical anomaly which coincides with elevated nickel values from previous aircore drilling in ultramafics.
He said the target, known as the Eastern Zone anomaly, is a chargeable IP anomaly which may be caused by disseminated sulphides.
The programme will consist of a single fence of RC holes drilled across the centre of the anomaly, providing samples of fresh rock for multi-element assays. These will determine whether the ultramafic is a fertile host for nickel mineralisation.
“Based on the data, this target is very promising and RC drilling is now needed to refine its prospectivity further,” Mr Paterson said.
“Having an anomaly supported by three different data sets in the same location is extremely compelling. In this case, we have the IP anomaly coincident with prospective ultramafic units and elevated nickel in aircore drilling.
“This initial drilling is designed as a proof of concept, taking samples for multi-element analysis to tell us if we’re in the right ballpark. If the results are positive, we’ll come back with a broader programme drilling fences of holes along strike.”
