Legend Mining Limited (ASX:LEG) has unveiled two target areas for diamond drill testing at the Octagonal prospect within the Rockford Project, Fraser Range, Western Australia following analysis of the 3D seismic and other data sets.

Both these target areas have multiple data sets supporting the potential for significant nickel copper sulphide accumulations and the Legend team are looking forward to the rods turning in a few weeks’ time,” Managing Director, Mark Wilson, said.

“They both qualify as the most exciting diamond drill targets the team have seen at our Rockford project since Legend started in the Fraser Range in 2015.”

Target generation, design, and ranking has been completed at Octagonal for the initial diamond drilling campaign for 2023 which will be focused on two areas.

Target area A will see a diamond drillhole target interpreted extensions of the Octagonal intrusion based on seismic interpretation. Beyond this, the drillhole will extend to test a highly chargeable IP anomaly before continuing to test the top of a large AMT conductor. Evidence from seismic data, IP and 3D AMT anomalies, structural interpretation, gravity modelling, and existing drilling data suggests excellent potential for the mineralised Octagonal intrusion extending outside the expressed ‘eye’ feature as depicted in the aeromagnetics.

Target area B will test a seismic feature interpreted as intrusion, associated with a conductive 2D AMT feature at depth. Structural analysis and seismic modelling, coupled with AMT modelling and proximal diamond drilling suggests the Octagonal intrusion extends at depth. Proximal drilling (OCT0002) indicates encouraging Ni-Cu mineralisation, further enhancing prospectivity of target area B.

The depth of the extensive Octagonal Intrusive Complex makes it blind to surface EM below 500m, therefore opening up a very large and prospective search space below current drilling. Both proposed diamond drillholes have a nominal planned depth of 1000m. Seismic has been a key tool in refining drill targets at depth.

All completed diamond drillholes will be subject to a suite of downhole geophysics, including EM and petrophysical property measurements, with collected data to aid in direct targeting for economic sulphide accumulations as well as refinement of the existing seismic cube.

Diamond drilling is scheduled to commence 15 May 2023.
