Earlier this week the company announced the discovery of a new, near-surface higher-grade zone of nickel sulphide bearing semi-massive sulphide veins (SMSV) at its Ta Khoa Nickel Project in Vietnam.
King Cobra discovery
This discovery, called King Cobra, includes near-surface downhole intervals of up to 60 metres and visual estimates of up to 20% sulphide mineralisation.
The new discovery includes the first-ever intersection of massive sulphide vein and breccia styles of sulphide mineralisation within the Ban Phuc intrusion which may provide vectors towards the high-grade ‘feeder zone’ mineralisation.
Blackstone aims to deliver a maiden resource on the DSS (disseminated sulphide) at Ban Phuc in the coming months and investigate the potential to restart the existing Ban Phuc concentrator through focused exploration on both MSV (massive sulphide vein) and DSS deposits.
A scoping study is underway on the downstream processing facility at Ta Khoa and this study will provide detail for potential joint venture partners to formalise a binding agreement.
Blackstone has also started metallurgical testing on the Ban Phuc DSS ore body with an aim to develop a flow sheet for a product suitable for the lithium-ion battery industry.
In addition, the company will investigate the potential to develop downstream processing infrastructure in Vietnam to produce a downstream nickel and cobalt product to supply Asia’s growing lithium-ion battery industry.
