Aldoro Resources encounters thicker zone of massive sulphides at VC1 target
Drilling will continue at Aldoro Resources’ VC1 target for the next three weeks before moving back to VC11 to test off-hole nickel sulphides.
Exploration company Aldoro Resources (ASX: ARN) has encountered a thicker zone of massive sulphide mineralisation at the VC1 target within the Narndee Igneous Complex nickel-copper-platinum group elements project in Western Australia.
The company intersected 3.74 metres of massive nickel-copper sulphide in a single interval, including 10.1m of heavy disseminated sulphide open to the east, west and north.
The significant intercept hit disseminated sulphide with one 6cm vein of massive sulphide from 265.75m to 275.86m depth; chalcopyrite-dominant veined sulphide from 277.1m to 277.3m and again from 281.1m to 281.4m; and massive sulphide from 277.3m to 281.1m.
The massive sulphide is believed to have “broken out” of the Narndee complex and entered the footwall basalt sequence of the drillhole, which is reported to be a favourable location for structural trap sites hosting more significant accumulations of nickel-copper sulphides.
The veined sulphides on the periphery of the massive sulphide are dominated by chalcopyrite, supporting the interpretation of remobilisation and metal segregation.
Sulphide assemblage
The sulphide assemblage in order of abundance intersected by all reported drillholes appears to be pyrrhotite, pentlandite, chalcopyrite and pyrite.
Visual estimates of the bulk sulphide abundance include disseminated, blebby, breccia, and or veined sulphide (1% to 20% sulphide); matrix sulphide (20% to 40%); semi-massive sulphide (40% to 80%); and massive sulphide (greater than 80%).
Aldoro said petrographic and geochemical analyses will be required to confirm the species, geological setting and relative abundance.
Forward plan
A reverse circulation rig will continue drilling the VC1 target for the next three weeks before demobilising to the Niobe project near Leinster, WA to complete lithium-rubidium resource drilling at Aldoro’s tenement.
A diamond rig has three holes left to drill at VC1, before it moves back to the VC11 target to test off-hole nickel sulphides.
Aldoro is also planning a deep stratigraphic hole between the VC3 and VC11 targets.
The company will continue a high-power fixed loop electromagnetic (HPFTLEM) survey to screen for deeper or very conductive targets at the VC1, VC3 and VC11 areas.
