Blackstone Minerals Advances to Pilot Plant and Ta Khoa Refinery DFS

THE DRILL SERGEANT: There was considerable activity at the Blackstone Minerals (ASX: BSX) exhibition booth at the 2021 Diggers & Dealers Forum in Kalgoorlie after the company announced it is set to commence the first phase of pilot plant work and a Definitive Feasibility Study (DFS) for the Ta Khoa Refinery (TKR) in northern Vietnam.

The decision to proceed with the DFS comes on the back of the company’s recent Ta Khoa Refinery Pre-Feasibility Study.

The first phase of piloting will be designed to process 20 kilograms per hour of nickel concentrate feed and will produce approximately 1.75kg per hour of nickel in nickel:cobalt:manganese (NCM) products.

“The Board’s endorsement of the recent PFS milestone has been rapidly followed by approval of the first phase of piloting and the Ta Khoa Refinery DFS,” Blackstone Minerals managing director Scott Williamson said in the company’s ASX announcement.

“The pilot plant process is an opportunity for Blackstone to optimise, with respect to quantity and quality, recent successful outcomes which include the production of its first battery grade NCM811 Precursor sample.

“The company is acutely aware of its first mover advantage and importantly, will be able to deploy its current balance sheet to continue to fast track the next important stages towards commercialisation of the Ta Khoa Refinery.”
