Legend Mining Ltd (ASX:LEG) is making strong progress with diamond drilling at Octagonal prospect within the Rockford Project in Western Australia's Fraser Range and is encouraged by the zones of nickel-copper sulphides returned.
The drilling has intersected narrow zones of nickel-copper sulphide mineralisation in Target (NYSE:TGT) Area A, including a zone of semi-massive, brecciated nickel-copper sulphide which has been remobilised into the metasedimentary country rocks.
This is further evidence of the Octagonal intrusion cracking into the surrounding country rock and an encouraging sign for the deposition of nickel-copper sulphide given the right structural trap.
Meanwhile, at Target Area B, hole 2 delivered some encouraging results, including a mineralised ultramafic intrusion with blebby nickel-copper sulphide and intense carbonate digestion at the base of the Octagonal intrusion.
Furthermore, Target Area C will see diamond drill hole OCDD004 target the interpreted ‘keel' zone of the Octagonal intrusion based on seismic interpretation.
Several encouraging aspects
Legend executive chair Mark Wilson said: “There have been several encouraging aspects to both holes drilled to date with semi-massive, brecciated nickel-copper sulphide remobilised into the country rock in hole 3 and mineralised intrusion at the basal contact in hole 2.
“It is important to note that neither hole has intersected the primary targets at Area A and Area B.
“We are awaiting downhole EM results from hole 3 before designing further holes at Area A, and a new hole 5 has been designed to test the primary targets at Area B, with hole 4 currently in progress into a new Target Area C.
“Further updates will be provided as results come to hand.”
Forward plan
The next steps at the Octagonal prospect include:
- diamond drilling of OCDD004 into Target Area C;
- diamond drilling of OCDD005 into Target Area B;
- DHTEM on OCDD003;
- DHTEM on OCDD004 and OCDD005 once completed;
- downhole petrophysics on completed drill holes; and
- assaying of selected intervals.
