Exploration company, Legend Mining (ASX:LEG) announces its diamond drilling (DD) is scheduled to begin on 15 May 2023 at the Octagonal prospect, within the Rockford Project in the Fraser Range of Western Australia.
The company reports this drilling program follows an analysis of the 3D seismic survey and other data sets, which identified 2 target areas for diamond drill testing.
Legend says the first target area will see a diamond drillhole target interpreted extensions of the Octagonal intrusion based on seismic interpretation. Additionally, this drillhole will extend to test a ‘highly’ chargeable IP anomaly before continuing to test the top of a large AMT conductor.
Evidence from previous data conducted suggests ‘excellent’ potential for the mineralised Octagonal intrusion extending outside the expressed ‘eye’ feature, which was uncovered in the aeromagnetics.
Meanwhile, the second target area will test a seismic feature interpreted as intrusions, associated with a conductive 2D AMT feature at depth. Structural analysis and seismic modelling, alongside AMT modelling and proximal DD suggests the Octagonal intrusion extends at depth.
Legend also notes proximal drilling in hole OCT0002 suggests ‘encouraging’ nickel-copper mineralisation, additionally enhancing the potential of the target area.
Commenting on the discovery for the initial campaign, Legend Mining Managing Director, Mark Wilson says: “Both of these target areas have multiple data sets supporting the potential for significant nickel-copper sulphide accumulations.
The Legend team are looking forward to the rods turning in a few weeks’ time. 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.”

Legend states that seismic data has been a key tool in refining the drill targets at depth.
Additionally, the company also notes all completed diamond drillholes will be subject to a suite of downhole geophysics, including EM and petrophysical property measurements.
Legend’s team will also collect data to support direct targeting for economic sulphide accumulations, as well as refinement of the existing seismic cube.
The Rockford Project covers a total area of 2,993km-square with the primary exploration focus on magmatic nickel-copper-cobalt, alongside volcanogenic massive sulphide style zinc-copper-silver, and Tropicana style structurally controlled gold mineralisation.
Legend Mining is an Australian exploration company, focused on its nickel-copper Rockford Project in the Fraser Range, Western Australia, with its joint venture partners and major shareholders Creasy Group and IGO.
