Legend Mining Limited (ASX:LEG) has confirmed that its sampling methods provide an accurate indication of nickel, copper and cobalt mineralisation at the Rockford project in Western Australia’s Fraser Range.
The company has resampled 4 metre composite samples obtained from aircore drilling of two holes at Area D of the project at 1 metre intervals.
The 1 metre resampling was designed to provide detailed geochemical information.

Mark Wilson, managing director, said: “These results are essentially a repeat of the earlier assays.
“They confirm that the 4 metre composite sampling methodology that we are employing gives an accurate indication of nickel, copper and cobalt numbers.”
The resampling has also confirmed the presence of anomalous copper values associated with the nickel, which reinforces the prospectivity of Area D.
The 1 metre results have identified several narrower intervals with higher grades.
Best individual samples were 1 metre at 0.47% nickel from 99 metres with associated 0.18% copper and 0.04% cobalt, and 1 metre at 0.17% nickel from 60 metres with associated 0.17% copper and 0.02% cobalt.
Further aircore drilling
After proving this method, the company will proceed with further aircore drilling at Area D.
Wilson said: “The new aircore program is designed to investigate the anomalous geochemical footprint around the two holes and more interesting magnetic/gravity features at Area D.”
$1.3 million R&D refund
Legend has received a $1.3 million R&D refund on its 2017 tax return.
The experimental innovative moving loop electromagnetic programs are ongoing and are expected to result in further R & D refunds.
Near-term work program
Legend’s near term exploration program at Rockford includes:
• Infill aircore drilling adjacent to the two drill holes to determine the extent of the anomalous nickel-copper-cobalt footprint;
• Complete final 20 holes of 2017 aircore program at Area D;
• Complete additional drill traverses over other aeromagnetic and gravity features at Area D;
• Results from the aircore drilling will be used to assist design of follow-up MLTEM surveying; and
• Further evaluation of previously identified EM conductors at Areas D, J, Q and U.
Legend works closely with Creasy Group
The majority of the 2,792.5 square kilometre Rockford project comprises seven contiguous exploration licences and is the subject of a joint venture between Legend (70%) and Creasy Group (30%).
Legend operates and manages the joint venture.
The remaining 262.5 square kilometres is 100% owned by Legend and includes five exploration licences.
