Aldoro Resources Ltd (ASX:ARN) has identified three areas for induced polarisation (IP) surveys targeting potential nickel-copper-PGE (Ni-Cu-PGE) mineralisation from its Narndee nickel exploration program in Western Australia.
The company is planning high-powered IP surveys over these three Ni-Cu-PGE targets following up on reinterpreted electromagnetics and past drilling results.
In addition, the IP will be conducted over the northern covered area at the Wyemandoo Project where structural interpretation of the aeromagnetic data suggests the potential for nickel-copper (Ni-Cu) mineralisation similar to that found at the nearby Canegrass Nickel Project.
Subject to the IP results, Aldoro proposes to contract a rig in the December quarter to test the deeper targets at both projects.
Narndee Project
The Narndee nickel-copper mineralisation model is similar to that successfully demonstrated by the Callisto Ni-Cu deposit in the Fraser Range held by Galileo Mining Ltd (ASX:GAL).
At Target 1, the planned east-west survey lines cover the previous drilling at VC01 and an area to the east.
At VC01, Ni-Cu mineralisation was intersected at the base of the ultramafic cumulate where they interface with mafics (including sediment). This contact appears to dip to the east.
Target 2 is situated 500 metres to the north of Target 1 and is based on a very strong aeromagnetic anomaly associated with VTEM and the PGE geochemical anomalies as well as surface gossans.
The model for this location is shown with a basal Ni-Cu ore body at depth with a faulted offset with possible associated PGE mineralisation.
Target 3 is located 2600 metres to the north of Target 2 and forms the southern part of a large, strong VTEM anomaly with overlapping aeromagnetic anomaly and includes nickel geochemical anomalies.
It is interpreted that the sulphide body could be significantly deeper than Target 2 and as such three 1200-metre east-west lines are proposed with 31 stations.
Windimurra Project
A proposed Gradient Array IP survey is planned over an area of about five square kilometres in the northern part of the Wyemandoo project.
The target is based on magnetic features offset from the major NNE-SSW magnetic linear associated with Huntsmen’s Canegrass Ni-Cu anomalies.
A concurrent soil sampling program is being planned over the high rechargeability anomaly areas.
The exploration target within this area is still the nickel sulphide style of deposit.
