THE DRILL SERGEANT: Blackstone Minerals (ASX: BSX) announced PGE assays from the maiden drill results at the company’s Ta Khoa nickel project in Northern Vietnam.
Blackstone Minerals declared the maiden PGE assays have potential to greatly the economics of the large unmined disseminated sulphide prospect at Ban Phuc with the initial three holes delivering results of:
22 metres at 0.76 per cent nickel, 0.13 per cent copper, 0.01 per cent cobalt and 0.4 grams per tonne PGE from 138m;
17.8m at 1 per cent nickel, 0.09 per cent copper, 0.01 per cent cobalt and 0.74g/t PGE from 106.6m; and
45.5m at 1.2 per cent nickel, 0.17 per cent copper, 0.01 per cent cobalt and 0.35g/t PGE from 56.5m.
Blackstone explained that its assays are the first ever PGE assays for the Ban Phuc disseminated sulphide zone (DSS), as previous owners focused entirely on massive sulphide veins (MSV) and only minimal PGE assays have been taken throughout the Ta Khoa nickel project.
The company’s drilling of the Ban Phuc DSS has delivered peak assays up to 3.4 per cent nickel and 2g/t PGE.
Blackstone considers the previously unrecognised PGE grades associated with the Ban Phuc DSS suggest a potential by-product credit could enhance the future economics of the Ta Khoa nickel project.
“Our maiden PGE assays from the Ban Phuc disseminated sulphide are a game-changer for the Ta Khoa nickel project,” Blackstone Mineral managing director Scott Williamson said in the company’s announcement to the Australian Securities Exchange.
“We look forward to better understanding the project’s full potential as we receive further assays from our drilling program.”
Blackstone is continuing with drilling at Ta Khoa to test high impact targets generated from a recently completed maiden induced polarisation (IP) survey.
Assays are also pending for the next four drill holes from the Ban Phuc disseminated sulphide zone.
The Ta Khoa nickel project is located 160 kilometres west of Hanoi.
The project includes the existing Ban Phuc nickel mine, which was built to Australian Standards and is currently under care and maintenance.
The Ban Phuc nickel mine operated as a mechanised underground nickel mine from 2013 to 2016.
