Blackstone Minerals Drilling Regional Ta Khoa Targets

THE DRILL SERGEANT: Blackstone Minerals has commenced drilling regional massive sulphide vein (MSV) targets at the company’s Ta Khoa nickel-PGE project in northern Vietnam.

Blackstone Minerals is targeting MSV prospects analogous to the previously mined Ban Phuc MSV, where previous owners mined high-grade ore between 2013 and 2016.

Blackstone’s ground-based electromagnetics (EM) geophysics crew recently generated a 1km long massive sulphide target within a 12km long district-scale exploration corridor, which the company aims to test over the coming months.

Drilling continues at the King Cobra discovery zone (KCZ) at depth and a second drill rig has commenced drilling the district-scale massive sulphide targets that have been generated by Blackstone’s inhouse geophysics crew.

Blackstone’s second drill rig will follow the geophysics crew throughout the Ta Khoa nickel sulphide district, testing high-priority EM targets generated from 25 MSV prospects including King Snake, Ban Khoa, Ban Chang, and Ban Khang.

Historic work at the Ta Khoa Nickel-PGE project highlighted a district of high-grade nickel sulphide targets that have not been tested extensively.

Blackstone intends systematically explore these using modern techniques for broader zones of MSV, initially at the Ban Chang prospect.

“By using our in-house geophysics crew and our own drill rigs, we can cost effectively explore this globally significant nickel sulphide district using modern geophysical techniques to unlock the significant potential of the world-class geology,” Blackstone Minerals managing director Scott Williamson said in the company’s announcement to the Australian Securities Exchange.

“We see potential to increase annual nickel production from the Ta Khoa Nickel-PGE project through targeting high-grade massive sulphide veins to complement the base load nickel sulphide feed to be potentially mined from the Ban Phuc DSS and King Cobra discovery zone.”
