THE DRILL SERGEANT: Blackstone Minerals (ASX: BSX) reported results from the final infill drill program at the Ban Phuc DSS deposit at the company’s Ta Khoa nickel–copper-PGE project in Northern Vietnam.
Blackstone Minerals declared the drilling had achieved some of the best broad DSS intersections to date at Ban Phuc, including a 375 metres nickel sulphide intersection to further demonstrate the large bulk tonnage potential of the Ban Phuc disseminated (DSS) deposit.
Latest results from Ban Phuc included:
374.7 metres at 0.3 per cent nickel, 0.01 per cent copper, 0.01 per cent cobalt and 0.07g/t PGE from 2m, including 49m at 0.45 per cent nickel, 0.04 per cent copper, 0.01 per cent cobalt and 0.17g/t PGE from 2m;
211.38m at 0.43 per cent nickel, 0.03 per cent copper, 0.01 per cent cobalt and 0.13g/t PGE from 111.62m, including 52.24m at 0.74 per cent nickel, 0.11 per cent copper, 0.01 per cent cobalt and 0.31g/t PGE1 from 241m;
156.25m at 0.5 per cent nickel, 0.07 per cent copper, 0.01 per cent cobalt and 0.15g/t PGE from 79.75m, including 31.05m at 0.75 per cent nickel, 0.14 per cent copper, 0.01 per cent cobalt and 0.26g/t PGE from 83.75m;
169m at 0.43 per cent nickel, 0.04 per cent copper, 0.01 per cent cobalt and 0.15g/t PGE from 62m, including 10.3m at 1.13 per cent nickel, 0.18 per cent copper, 0.02 per cent cobalt and 0.48g/t PGE from 98m; and
52m at 0.79 per cent nickel, 0.1 per cent copper, 0.01 per cent cobalt and 0.26g/t PGE from 22m, including 30m at 1.1 per cent nickel, 0.14 per cent copper, 0.02 per cent cobalt and 0.41g/t PGE from 40m;
The Ban Phuc DSS deposit is anticipated to underpin the Upstream Business Unit (UBU) PFS due later this calendar year.
Completion of the final infill drilling program is aimed at increasing the confidence of the existing JORC resource of:
Indicated Mineral Resource of 44.3 million tonnes at 0.52 per cent nickel for 229,000 tonnes nickel; and
Inferred Mineral Resource of 14.3 million tonnes at 0.35 per cent nickel for 50,000 tonnes nickel.
“The high tenor of results from the final infill drilling program increases the confidence of the resource at Ban Phuc, and the mine plan that will underpin Blackstone’s UBU PFS,” Blackstone Minerals managing director Scott Williamson said in the company’s ASX announcement.
“In the relatively short amount of time since acquiring the Ta Khoa nickel-copper-PGE project, Blackstone has been able to define a large, disseminated sulphide deposit which considerably adds to the security of supply for the company’s vertically integrated downstream refinery.”
