Estrella Resources Limited (ASX: ESR) has intersected several significant zones of nickel and copper sulphides in its latest hole drilled on the Carr Boyd Nickel Project in Western Australia.
The company reported that hole NCB001 intersected the basal contact at approximately 122.6m downhole. Significant zones of nickel and copper sulphides were intersected, both within the CBLC, on the basal contact, and in the immediate footwall from HXRF readings.
Estrella CEO, Christopher Daws, said the result has provided further vindication of the target model being pursued at Sir William Wallace, even though the EM conductor source was attributed to a sulphide black shale horizon outside of the intrusion further downhole.
Mr Daws said the basal contact was intersected significantly shallower than previously anticipated and the hole has provided invaluable information about the position and geometry of the basal contact of the CBLC, which appears to be dipping at -75 degrees to the north and is mineralised.

A second hole now has been designed to test the basal contact up dip of the NCB0001 pierce point.
“This will provide more accurate control on the position and orientation of the basal contact,” Mr Daws said.
“The information generated will allow for refined positioning of the co-funded drillhole to screen a larger area of the contact. If any significant off hole conductors are generated associated with the nickel-copper sulphide intercepts in NCB0001, the design of the follow-up hole will be adjusted accordingly,” he added.
The CBLC is a 75km2 layered mafic igneous complex, which hosts several occurrences of nickel and copper sulphides. The most significant occurrence discovered to date is at the Carr Boyd Rocks mine, located approximately 80km north north-east of Kalgoorlie.
