Legend Mining Ltd (ASX:LEG) has started diamond drilling of Target (NYSE:TGT) Area A targeting nickel-copper sulphides in the interpreted extensions of the Octagonal intrusion at Octagonal Prospect within the Rockford Project in Western Australia’s Fraser Range.
The extensions being targeted in hole OCDD003 are based on seismic interpretation.
This hole will also extend to test a higher chargeable IP anomaly before continuing to test the top of a large AMT conductor.
Legend believes that evidence from seismic data, IP and 3D AMT anomalies, structural interpretation, gravity modelling and existing drilling data suggests strong potential for the mineralised Octagonal intrusion extending outside the expressed ‘eye’ feature as depicted in aeromagnetics.
Priority target areas and proposed diamond drill holes with Octagonal intrusion model, IP anomalies, 2D & 3D AMT anomalies and existing drilling with visual nickel-copper mineralisation on AMAG.
Wedge drill hole plan
The company also intends to return to diamond hole OCDD002 into Target Area B after this hole drilled off the planned trajectory, which would result in the drill hole missing the targets if drilling continued.
As a result, Legend decided to stop the hole short of the seismic and AMT targets.
Wedge and navi gear are now being mobilised to site and will be deployed to realign the drill trace to hit the target zone as originally planned.
Prior to drilling a wedge drill hole, DHTEM will be conducted on OCDD002 to test for conductors and this is scheduled to be carried out within a week.
This delay with hole OCDD002 saw Legend decide to move to hole OCDD003 in order to eliminate downtime.
