Aldoro Resources Ltd (ASX:ARN) has revealed the latest results from its second diamond drill hole, testing the VC1 target at the Narndee Igneous Complex in Western Australia.
The company’s drill hole NDD0002 intersected significantly thicker and stronger zones of massive, semi-massive, blebby, and veined nickel-copper sulphides than NDD0001.
Notably, Aldoro’s portable XRF analyses confirmed nickel and copper are present in the sulphides.
Multiple discrete ultramafic intrusions
NDD0002 was designed to test a shallower up plunge position of the VC1 electromagnetic (EM) conductor 85 metres south-southwest of NDD0001.
The drill hole intersected about 3.6 metres of massive sulphide (two zones), 0.5 metres of semi-massive sulphide (one zone), and 6.9 metres of veined, blebby, and breccia sulphide (two zones).
Aldoro also noted that the multiple discrete ultramafic intrusions observed in NDD0001 appear to have coalesced into a single thick ultramafic package in NDD0002.
Massive sulphide thickening to the south
NDD0002’s massive sulphide mineralisation appears to be thickening to the south and contains a significant amount of magnetite inclusions.
The sulphide assemblage in order of abundance intersected by NDD0002 appears to be pyrrhotite, pentlandite, and chalcopyrite.
However, petrographic and geochemical analyses are required to confirm the species, geological setting, and relative abundance.
Importantly, NDD0002 intersected significant zones of quartz veining, disseminated sulphides, and bleaching in the footwall sequence.
Forward plan
Aldoro’s third hole, NDD0003, will be drilled 85 metres south-southwest of NDD0002 to track the thicker sulphide accumulation further up plunge to the south.
The company is awaiting the downhole EM contractor to arrive on site.
Downhole EM will be conducted on all holes completed at VC1 to aid and refine drill targeting.
There will now be four holes to DHTEM survey this week with the results expected to significantly refine the models for follow-up drill targeting.
