THE DRILL SERGEANT: Blackstone Minerals (ASX: BSX) has continued it run of intersecting high-grade massive sulphide nickel-copper-PGE at Ban Chang, part of the company’s Ta Khoa nickel-copper-PGE project in Vietnam.
The first four holes of Blackstone Minerals’ maiden drilling program at Ban Chang have all encountered sulphide mineralisation.
The latest of these, BC20-04, returned:
21.5 metres at 0.69 per cent nickel, 0.66 per cent copper, 0.03 per cent cobalt and 0.81 grams per tonne PGE from 71m
13.4m at 1.01 per cent nickel, 0.96 per cent copper, 0.05 per cent cobalt and 1.14g/t PGE from 76m, including 2.1m at 2.53 per cent nickel, 1.36 per cent copper, 0.11 per cent cobalt and 0.76g/t PGE from 77.6m.
The four maiden drill holes were drilled more than 1.2 kilometres apart and along strike within a 1.2km-long massive sulphide target zone defined by high priority EM plates.
Blackstone has now moved to an aggressive drill out phase to delineate a maiden resource at Ban Chang to supplement the ongoing studies focused on producing nickel sulphate for the lithium-ion battery industry.
The company has recently purchased a third drill rig that will follow its 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 Ta Cuong.
The largest of these rigs will continue drilling at the King Cobra Discovery zone (KCZ), while the two smaller drill rigs will operate at Ban Chang East and Ban Chang West.
Blackstone’s Scoping Study on downstream processing to produce nickel sulphate for the lithium-ion battery industry and Ban Phuc maiden resource are on track for completion in Q3, CY20.
“Hole 4 has delivered our broadest Ban Chang intersection to date and confirms we have a bulk tonnage opportunity that has potential to deliver significant high-grade nickel to our future mine plan which will be underpinned by a base load feed coming from our flagship Ban Phuc orebody which includes the KCZ,” Blackstone Minerals managing director Scott Williamson said in the company’s announcement to the Australian Securities Exchange.
“Ban Chang is 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 KCZ.”
