Blackstone Minerals Hits 200m High-grade nickel-copper-PGE Zone

THE DRILL SERGEANT: Blackstone Minerals (ASX: BSX) has continued to encounter massive sulphide in its maiden drilling program underway at the Ban Chang target, part of the company’s Ta Khoa nickel-copper-PGE project in Vietnam.

Blackstone Mineral’s drill hole BC20-02 at Ban Chang hit a 200 metres long zone of high-grade nickel-copper-PGE with the following high-grade results:


4.1 metres at 0.92 per cent nickel, 0.69 per cent copper, 0.05 per cent cobalt and 0.26 grams per tonne PGE from 85.9m:


2.3m at 1.6 per cent nickel, 1.09 per cent copper, 0.09 per cent cobalt and 0.43g/t PGE from 85.9m, including 1.8m at 2.01 per cent nickel, 1.27 per cent copper, 0.12 per cent cobalt and 0.53g/t PGE from 86.4m.

All four holes Blackstone has drilled to date at Ban Chang have intersected massive sulphide nickel over a 1.2km strike within a 1.2km long massive sulphide target zone defined by high priority electromagnetic (EM) plates.

Assays are pending for drill hole BC20-04, which intersected 15.4m of sulphide vein mineralisation.

“Our latest assays confirm further high-grade mineralisation at Ban Chang,” Blackstone Minerals managing director Scott Williamson said in the company’s announcement to the Australian Securities Exchange.

“We continue to demonstrate 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 1.3 metre wide MSV at much lower nickel prices than today.

“We are seeing broader widths and significant by-products which could lend to potentially better economics than when this mine previously operated.

“We have now drilled significant massive sulphide nickel mineralisation over 1.2 kilometres of strike at Ban Chang and our in-house geophysics crew continues to test for further massive sulphide mineralisation at the new target, Ta Cuong.

“Ban Chang and Ta Cuong are the first of our 25 MSV targets to be tested throughout the Ta Khoa nickel-copper-PGE district, leaving plenty of upside for adding high-grade feed to what looks like a bulk open pit mining scenario at Ban Phuc and the King Cobra Discovery zone.”
