LITHIUM: Nemaska preps Whabouchi site for 60,000-t bulk sample

QUEBEC – Nemaska Lithium of Quebec City has begun to prepare the Whabouchi site 300 km northwest of Chibougamau for the mining of a 60,000-tonne bulk sample and installation of a modular mineral processing plant.

The company has applied for permission to install and operate a new modular dense media separation (DMS) mill with a capacity of 10 t/h. A concentrate containing 6% Li2O will be further processed in Nemaska’s hydrometallurgical plant in Shawinigan, QC. The mill should be operational in October and operate over the next 12 to 18 months. Part of the DMS material will be passed through a flotation circuit before shipment to the hydromet plant.

Originally, Nemaska planned to take a 29,000-tonne sample, but has recently more than doubled the target. The Whabouchi deposit has indicated and measured resources of 28.0 million tonnes grading 1.57% Li2O, and another 4.7 million inferred tonnes at 1.51% Li2O.
