LITHIUM: Nemaska buys modular mill for Whabouchi bulk sample

QUEBEC – Nemaska Lithium of Quebec City has purchased a self-contained dense media separation (DMS) portable mill to treat ore from the 29,000-tonne Whabouchi lithium bulk sample program. The modular mill will treat 10 t/h and operate this summer and fall.

The mill will be situated at the Whabouchi site on an area already permitted by both the provincial and federal authorities for commercial production. The mill comes with its own generators, lab, workstation and change rooms. It will also serve as a training facility for the local Cree workforce wanting to become mill operators.

Nemaska is paying $750,000 in cash plus 3 million shares for the modular plant. When the bulk sample is completed, the company can either resell the plant or use it for metallurgical testing of other ores on a toll milling arrangement.

A 6% Li2O spodumene concentrate will be produced. The concentrate will meet feed requirements for Nemaska’s lithium hydroxide and lithium carbonate demonstration plant in Shawinigan, QC. More information about the plant is posted at
