TA KHOA PROJECT

The Ta Khoa Nickel-Copper-PGE Project is located 160 km west of Hanoi in the Son La Province of Vietnam and includes an existing modern nickel mine built to Australian standards, which is currently under care and maintenance. The Ban Phuc nickel mine successfully operated as a mechanised underground nickel mine from 2013 to 2016.

INTERNATIONALLY DESIGNED 450 KTPA PROCESSING PLANT
Downstream Pre-feasibility Study

Blackstone Minerals Downstream Pre-feasibility Study confirms technically and economically robust hydrometallurgical refining process to upgrade nickel sulfide concentrate to produce battery grade Nickel: Cobalt: Manganese (NCM) 811 Precursor for the Lithium-ion battery industry.

  • Average annual copper by-product of 4.1ktpa

Scoping Study

Blackstone Minerals completed a Scoping Study for the development and restart of the Ta Khoa Nickel-Cu-PGE Project. The Project comprises an open pit mine at the Ban Phuc Disseminated Sulfide, upstream processing and downstream processing to produce a Precursor product for Asia’s growing Lithium-ion Battery Industry.  

 

The Scoping Study is an important milestone and an initial platform to build a mine-to-market nickel business over the coming years with multiple upside opportunities to improve on the Scoping Study as presented. Blackstone looks forward to developing the Ta Khoa Project and has immediately commenced the next phase of Pre-Feasibility Studies.
