Nemaska Lithium Inc. ("Nemaska Lithium" or the "Corporation") (TSX:
NMX)(OTCQX: NMKEF) announced today the results of its initial
production of spodumene concentrate from the Whabouchi Mine, using a
mine representative bulk sample. The plant is running continuously at
half its capacity, 12 hours per day since March 7, 2017. Operation is
steadily ramping up and should reach a throughput of around 150 tpd.

Recent results from concentrate composite samples, produced on a
6-hour basis, yielded the following results:

March 7 (AM) - 2.89% Li = 6.22% Li2O

March 8 (AM) - 3.05% Li = 6.56% Li2O

March 8 (PM) - 3.09% Li = 6.65% Li2O

"Generally speaking, the hard rock lithium industry requires a 6%
concentrate or higher to efficiently produce battery grade lithium
salts," said Guy Bourassa, President and CEO of Nemaska Lithium. "We
have seen other hard rock producers struggle to achieve this quality
concentrate, making it more technically challenging and costly to
produce battery grade lithium salts. With this concentrate production
we have met another important milestone as we continue to de-risk our
project."

It is expected that Nemaska Lithium will process sufficient raw ore
minerals in the DMS plant to provide 650 tons of spodumene
concentrate with a view to producing lithium hydroxide samples in the
Phase 1 Plant in Shawinigan, for qualification by potential
customers.

"The operations team at Whabouchi is working diligently to ramp up
the DMS mill to full run rate over the next few weeks per our
schedule," said Francois Godin, Vice President Operations. "We have
been working closely with DMS experts from around the world to ensure
the plant start-up is smooth and high quality concentrate is
produced. We've learned a tremendous amount that will be directly
applicable to the start-up of the commercial concentrator. I look
forward to updating you further as we log more hours on the DMS
mill."
