Legend Mining strengthens eastern geochemical footprint at Mawson massive sulphide discovery

The extended footprint is a “compelling” target for reverse circulation/diamond drilling which is already underway.

Aircore drilling at Mawson prospect within the Rockford Project on Fraser Range

Legend Mining Limited (ASX:LEG) has received new broad assay results that extend and strengthen the eastern geochemical footprint of the Mawson massive sulphide discovery within the Rockford Project in WA’s Fraser Range.

Assays have been received from infill aircore drilling within the eastern geochemical nickel-copper footprint, east and northeast of the discovery.

These include 38 metres at 0.20% nickel, 0.05% copper and 0.03% cobalt from 72 metres to the end of hole (EOH) and 43 metres at 0.12% nickel, 0.02% copper, 0.02% cobalt from 64 metres to EOH.

“A compelling target”

Legend managing director Mark Wilson said: “These results are from the ongoing infill aircore program at Mawson and have extended and strengthened the eastern geochemical footprint.

"This footprint is a compelling target for RC/diamond drilling which is already underway.”

The company has received results from an additional 37 holes with six returning broad intervals with anomalous nickel and copper values associated with mafic/ultramafic intrusives.

Anomaly defined

These and previous aircore results have defined the NE-SW trending eastern geochemical anomaly over an area of 1,200 x 200 metres.

The results from drill holes RKAC838-842 along with previous holes have returned broad intersections ranging from 21 to 43 metres with anomalous nickel-copper over 400 metres in a north-south direction.

Legend’s current aircore program over the greater Mawson area is scheduled to conclude within a fortnight following the completion of infill drilling over southern and north-eastern targets.

The rig will then move on to a 180 hole 10,000-metre regional aircore program over the western and southern tenements in the Rockford Project.

Future programs

  • Complete infill aircore drill program across the greater Mawson area;
  • Continue 3,000-metre RC drilling program targeting anomalous aircore geochemistry and gravity features; and
  • Ongoing integration of aircore and RC drilling into the Mawson dataset to assist future RC/diamond drill hole planning/design.
