Estrella Resources Limited (ASX: ESR) has drilled another two significant sulphide intersections at its 100% owned Carr Boyd Nickel Project 80km north northeast of Kalgoorlie.
Assays received for diamond drillhole CBDD054A returned a significant width of nickel-copper mineralisation.
The drillhole intersected 26.3m (12.6m true width) @ 0.73% Ni & 0.44% Cu, 1.84g/t Ag & 0.46g/t Pt + Pd including several higher-grade massive breccia sulphide zones with significant platinum group elements (PGE) results.
There are currently four drillholes with laboratory results pending. These are due within the next two weeks. The latest hole to be completed, CBDD055B, is currently being logged and sampled.
CBDD055A and CBDD055B have intersected a broad zone of nickel-copper-iron sulphide mineralisation with several massive and semi-massive sulphide zones on and above the basal contact.
The area targeted by these holes is the central to top portion of the Upper T5 Conductor. The strong mineralisation revealed by the drilling appears to confirm the south plunge of the Upper T5 Conductor.
Estrella Managing Director, Chris Daws, said examination of the core from the Phase 3 drilling has shown that there is the strong possibility that the T5 Conductor is one of several south-plunging targets along the surface of the T5 Basal Contact.
He said, “The flow of the host pyroxenite appears to have been sufficient to allow for the accumulation and redeposition of massive sulphides perpendicular to the flow direction. These “banks” of deposited sulphides appear to be connected within a halo of blebby to globular sulphides. Just two of these “banks” have been drilled (the Upper and Lower T5 Conductors) in what seems to be quite a small area with respect to the prospective surface of the T5 Basal Contact.”
We have continued to hit mineralisation with a very high success rate at our 100% owned Carr Boyd nickel-copper sulphide project,” Mr Daws said.
“Our belief is firming that the source of the Carr Boyd sulphides will be located. You simply don’t see the quantity and nature of sulphides that we are currently drilling and what is located at the historic Carr Boyd Ni-Cu mine without it first forming elsewhere. We are very well funded to conduct the exploration programme from here which will be a very exciting time for the Company and its shareholders.”
Current drilling is targeting an area just south of the Carr Boyd Rocks Mine to test the T5 Basal Contact in relation to several high-reflectance targets generated from the recent seismic program and to help constrain the seismic interpretation in this area.
The drillhole CBDD052 will serve as a Downhole Electromagnetic (DHEM) platform to test for northern extensions of the Carr Boyd Rocks mineralisation as well as an extension to the T5 Conductor mineralisation on the basal contact.
Upon completion, the rig will return to the northern T5 contact to begin a series of RC pre-collars to test the down-plunge extensions of the Upper T5 Conductor as well as an RC campaign targeting some 3.5km of potential north of the current drill area.
