Special Report: “Wherever we have drilled an electromagnetic (EM) conductor at Andover, we have intersected nickel-copper sulphide mineralisation,” Azure Minerals (ASX:AZS) managing director Tony Rovira says.

All six holes completed to date by Azure have intersected broad intervals of substantial nickel copper sulphide mineralisation.

EM surveys map sub-surface changes in electrical conductivity and are useful – but not usually perfect — tools for finding nickel sulphides.

But in every hole at Andover massive sulphides (the best stuff) coincide with strong electromagnetic conductors detected by EM surveys.

A 100 per cent hit rate.

The most recent hole, ANDD0006, hit a 53.6m-wide mineralised envelope containing significant intervals of nickel-copper sulphides from a downhole depth of 371.9m.

That includes several zones of massive and semi-massive sulphides about 53m below similar nickel-copper sulphide hits intersected in ANDD0004.

This nickel and copper was intersected at the downhole depth predicted by the electromagnetic survey.

“The three diamond holes we’ve drilled into the VC-07 conductor have all intersected broad zones containing substantial quantities of nickel-copper sulphide mineralisation on a section that now has a vertical extent in excess of 100m,” Rovira says.

“The most recent and deepest of these holes, ANDD0006, has returned the widest mineralised zone with an intersection width of 53.6m, suggesting that the mineralised zone is not only open in the down-dip direction but broadening with increasing depth, which is very encouraging.

“We’re now stepping out to test the VC-07 conductor plate along strike to the west and if VC-07 continues to deliver similar mineralised intersections along its more than one-kilometre length, there is the potential to define a substantial nickel-copper sulphide deposit at Andover.”

ANDD0003 has also returned the highest-grade nickel intersection to date of 4.09 per cent.

Assay results include:

– 2.5m @ 1.1 per cent nickel and 0.6 per cent copper from 41.3m;

– 9.9m @ 0.9 per cent nickel and 0.3 per cent copper from 62.1m, and

– 4.6m @ 2.1% nickel and 0.2% copper from 78.4m (includes highest grade nickel intersection to date of: 0.85m @ 4.09 per cent nickel)

Assays for holes ANDD0004, ANDD0005 and ANDD0006 are pending.
