Aldoro Resources Limited ( Aldoro , The Company ) ( ASX: ARN ) is pleased to provide an exploration update for the VC1 and VC3 targets at the Narndee Igneous Complex (NIC, The Project) . NDD0005 at the VC3 target and a further three holes at VC1 have been completed. Assay results have been returned for NDD0001 and NDD0002, confirming the prospectivity of VC1 and the NIC.

About VC1 Results and Drill Targeting
NDD0006, NDD0007, and NDD0008 have been completed at VC1 since the previous update. A limited batch of high priority assay results were returned for NDD0001 and NDD0002. Both holes returned significant results for nickel, copper, cobalt, and palladium, which are as follows;

NDD0001
- 1.65m at 0.93% Ni, 0.15% Cu, 0.07% Co, and 0.22ppm Pd from 212.75m Including 0.4m at 1.05% Ni from 214m
NDD0002
- 3.8m at 0.78% Ni, 0.46% Cu, 0.06% Co, and 0.26ppm Pd from 146.4m Including 0.1m at 2.00% Cu and 1.03 g/t Pd from 146.75m
All seven holes drilled at the VC1 target by the Company have returned significant zones of magmatic sulphides. This confirms VC1 as a significant discovery and demonstrates the high prospectivity of the NIC.

Figure 2. Plan projection showing completed drillhole pierce points of the VC1 target and an evolving interpretation of the magmatic sulphide footprint. DHTEM surveying generated a revised off-hole target shown in red.
The magmatic sulphides at VC1 appear to show significant variation in nickel tenor and metal ratios, which will need to be confirmed by laboratory assays. There also appears to be a lack of identifiable igneous textures in the sulphides, which are often injected into the footwall sequence, and contain thermally eroded footwall xenoliths. This suggests that the mineralisation has undergone significant remobilisation and post-depositional recrystallisation. If preferential remobilisation and metal

segregation has occurred, the potential exists for higher-grade nickel at the VC1 target. The unusually high copper to nickel ratio is further evidence for this phenomenon.

VC3 Visual Results
NDD0005 was drilled to a depth of 654.9m. The hole was extended as it re-entered a high MgO ultramafic package with occasional disseminations of magmatic sulphides after passing through the VC3 target. This confirms the VC3 area to be highly prospective for nickel-copper PGE mineralisation, particularly at depth.
The VC3 target was intersected at approximately 380m downhole. The anomaly appears to be associated with an internal raft of sulphidic metasediment, hosted by high MgO ultramafics and mafics. The rocks immediately below the metasediment contain blebby and disseminated magmatic sulphide, confirmed to be nickel and copper-rich by pXRF.
The Company is now considering deeper penetrating geophysical techniques, such as large loop high power electromagnetics, to assess the potential of the highly prospective target area between VC1 and VC3.

The sulphide assemblage in order of abundance intersected by all reported drillholes appears to be pyrrhotite, pentlandite, chalcopyrite, and pyrite. However, petrographic and geochemical analyses are required to confirm the species, geological setting, and relative abundance. Bulk sulphide abundance definitions are as follows (note these are visual estimates);
-
Disseminated, blebby, breccia, and or veined sulphide - 1% to 20% sulphide
-
Matrix sulphide - 20% to 40% sulphide
-
Semi massive sulphide - 40% to 80% sulphide
-
Massive sulphide - greater than 80% sulphide
VTEM and Aeromagnetic Dataset Extensions
Given the high success rate of the existing VTEM survey, extensions are proposed to screen the remaining areas of highly prospective stratigraphy and geochemistry results. The proposed extensions are divided into Priority 1 over nickel-copper-PGE magmatic sulphide style targets and Priority 2 over copper-gold VHMS style targets.

Forward Plan
The drill rig will complete another hole to the east of NDD0003, where the best sulphide accumulations have been intersected. It will then move to the VC11 target, which shows very similar lithological and geophysical characteristics to the VC1 target.
