Blackstone Minerals Extends Ban Chang Prospect

THE DRILL SERGEANT: Blackstone Minerals (ASX: BSX) has extended the strike of the Ban Chang prospect at the company’s Ta Khoa Nickel-Cu-PGE project in Vietnam.

Blackstone Minerals announced it has extended Ban Chang by more than one kilometre by way of step out reconnaissance style drilling intersecting high-grade mineralisation.

Drill holes were drilled more than 1.2km apart and along strike within a 1.2km-long massive sulphide target zone defined by high-priority EM plates.

Drillhole BC20-03 followed up on previously encountered mineralisation, returning:

9.8 metres at 1.45 per cent nickel, 0.9 per cent copper, 0.08 per cent cobalt 0.7g/t PGE from 57.05m; and
5.7m at 2.07 per cent nickel, 1.08 per cent copper, 0.12 per cent cobalt and 0.95g/t PGE from 60m, including 1.85 at 3.59 per cent nickel, 1.18 per cent copper, 0.2 per cent cobalt and 1.97g/t PGE from 63.35m.

“Our latest assays confirmed a new zone of high-grade mineralisation which was previously untested,” Blackstone Minerals managing director Scott Williamson said in the company’s announcement to the Australian Securities Exchange.

“We have demonstrated strong potential for a bulk underground mining scenario at Ban Chang, which could be significantly larger scale than the previously mined Ban Phuc massive sulphide underground mine.

“At Ban Phuc, the previous owners successfully mined a narrow massive sulphide vein at much lower nickel prices than today.

“With bulk underground mining and the potential for significant PGE credits, we could be looking at a very economic mining scenario at Ban Chang.

“We have now drilled significant massive sulphide nickel mineralisation over one kilometre of strike at Ban Chang and our in-house geophysics crew continues to test for further massive sulphide mineralisation.

“Ban Chang is the first of 25 MSV targets to be tested throughout the Ta Khoa nickel-copper-PGE district, leaving plenty of upside for adding high-grade feed to a bulk open pit mining scenario at Ban Phuc.”
