Legend Mining assays continue to develop nickel-copper footprint at Mawson

A second batch of assays from aircore drilling have further defined a large coherent nickel-copper geochemical footprint east and northeast of the Mawson massive sulphide.

Legend Mining Limited (ASX:LEG) assays are beginning to define a large coherent geochemical anomaly east of the main Mawson sulphide mineralisation within the Rockford Project in WA’s Fraser Range.

The company has received the second batch of assay results from recent aircore drill holes at Mawson.

Eight of 18 holes returned anomalous nickel and copper values associated with mafic/ultramafic intrusives including up to 24 metres at 0.36% nickel, 0.22% copper and 0.04% cobalt from 60 metres to the end of hole.

“Important indicator”

Legend managing director Mark Wilson said: “The developing geochemical footprint of anomalous nickel-copper assays at Mawson is seen as an important indicator of the possible source of the massive sulphides we have discovered recently.

“The aircore drilling program in this area is ongoing and once complete we will have a clearer picture of the detail of this footprint.”

Strong results

Other strong results from the latest batch are:

  • 22 metres at 0.29% nickel, 0.16% copper and 0.02% cobalt from 60 metres to the end of hole; and
  • 17 metres at 0.19% nickel, 0.14% copper and 0.02% cobalt from 52 metres to the end of hole.

The results are associated with olivine bearing mafic/ultramafic host rocks.

These and previous aircore results are beginning to outline a large NE-SW trending coherent geochemical anomaly to the east of the main Mawson sulphide mineralisation.

The position of this geochemical feature coincides with the centre of an oval-shaped magnetic feature and a 4mgal gravity high.

Work program

Further infill aircore drilling is underway aimed at defining the extent of the anomalism.

Legend is also carrying out a detailed gravity survey over the main Mawson gravity high.

Results of this and the aircore data will assist the company in future reverse circulation/diamond drill hole planning/design.

The company also plans to continue a diamond drilling program targeting extensions to the nickel-copper mineralisation.
