Legend Mining up after intersecting 24.65 metres of nickel-copper sulphides at Mawson

“We have now intersected significant mineralisation several hundred metres to the ENE of our previous discovery and our geophysical advice is that we probably have not hit the best part of this conductor,” says MD.

Legend Mining Limited (ASX:LEG) is higher after intersecting a total of 24.65 metres of nickel-copper sulphides in a diamond hole at Mawson prospect within the Rockford Project on WA’s Fraser Range.

Hole RKDD021 intersected two encouraging intervals - 9.3 metres of heavy disseminated to net-textured sulphide from 132.2 metres and 15.35 metres of net-textured, heavy disseminated and semi-massive sulphide from 219.1 metres.

This hole was designed to test a strong (12,000-14,000S) off hole conductor identified from a downhole electromagnetic survey (DHTEM) in hole RKRC013.

Shares up 19%

Shares have been as much as 19% higher in the first hour to 16 cents.

Legend managing director Mark Wilson said: “The observations from this step-out hole are an exciting development in the Mawson story.

“Geologically we have now intersected significant mineralisation several hundred metres to the ENE of our previous discovery and our geophysical advice is that we probably have not hit the best part of this conductor.”

Two intrusive packages

The two intervals in hole RKDD021 were across two intrusive packages separated by a metasedimentary unit.

The lower mineralised interval ended at 234.45 metres downhole before intersecting a metasedimentary unit, interpreted as a basal contact.

Both nickel-copper sulphide intervals occur within fertile mafic-ultramafic intrusive packages, not metasediments, suggesting that the intrusive source of the previously intersected Mawson mineralisation has potentially been identified.

Net-textured nickel-copper sulphide mineralisation from RKDD021 from 140.5 metres.

DHTEM crew mobilising

A DHTEM crew and expert structural geologist are mobilising to site with DHTEM is to be completed in RKDD021, and in the adjacent RKRC021, which was drilled to provide an additional DHTEM platform in this location.

This will facilitate additional vectoring of nickel-copper mineralisation intersected in RKDD021.

Drill core from RKDD021 will be structurally logged before being sampled and submitted for analysis.

Wilson said: “Our proven systematic methodology of DHTEM and structural logging of this hole on completion will provide the data for the design of the next diamond holes in this immediate vicinity.

“Meanwhile the diamond, RC and aircore programs are ongoing at Mawson and regionally within the Rockford Project.”

Future programs

The company’s upcoming work program includes:

  • Complete DHTEM surveying in diamond drill hole RKDD021;
  • Complete DHTEM in RC drill holes RKRC015-021 and process/interpret results;
  • Structural logging of RKDD021 drill core by Jon Standing from Model Earth;
  • Continue RC drilling program testing the eastern geochemical anomaly;
  • Complete infill aircore drill program across the greater Mawson area; and
  • Ongoing integration of diamond, RC and aircore drilling results into the Mawson dataset to assist future diamond drill hole planning/design.
