"Cathode producers are primarily concerned with the impurity levels in the lithium hydroxide they receive from suppliers, as these impurities impact the overall performance of the battery. Our lithium hydroxide compares very favourably to that of our peers in the industry and is well within the acceptable specification limits of cathode producers globally. Following discussions with multiple cathode makers, I believe ours is one of the best lithium hydroxide products available today," said Guy Bourassa, President and CEO of Nemaska Lithium.

In addition, Nemaska Lithium is pleased to report that it has received an installment payment of C$4.6M from Sustainable Development Technology Canada (SDTC) for having achieved the second milestone in the development of the Phase 1 Lithium Hydroxide Plant.

About Nemaska Lithium

Nemaska Lithium's vision is to "Facilitate access to green energy through its products and processes, for the benefit of humanity". It intends to become a lithium hydroxide and lithium carbonate supplier to the emerging lithium battery market that is largely driven by electric vehicles, energy storage, cell phones, tablets and other consumer products. The Corporation is developing in Québec, Canada, one of the most important spodumene lithium hard rock deposit in the world, both in volume and grade. The spodumene concentrate produced at Nemaska Lithium's Whabouchi mine will be shipped to the Corporation's lithium compounds processing plant to be built in Shawinigan, Quebec. This plant will transform spodumene concentrate into high purity lithium hydroxide and carbonate using the proprietary methods developed by the Corporation, and for which the Corporation holds nine issued patents and several patent applications that are pending in different countries, covering different aspects and improvements of its proprietary technology for preparing high purity lithium hydroxide and carbonate, in an eco-friendly fashion.
