05 May 2017

QUÉBEC CITY, QUÉBEC--(Marketwired - May 5, 2017) - Nemaska Lithium Inc. and its wholly-owned subsidiaries (collectively, "Nemaska Lithium" or the "Corporation") (TSX:NMX)(OTCQX:NMKEF) and Johnson Matthey Battery Materials Ltd ("JMBM") of Candiac, Québec, a wholly-owned subsidiary of Johnson Matthey Plc (LSE:JMAT) ( announced today that JMBM has made an early payment of CAD$2,000,000 (of the final CAD$3,000,000 milestone payment) following receipt of the first shipment of lithium hydroxide (see press releases of May 11, 2016 and April 17, 2017). The final CAD$1,000,000 will be paid by JMBM once Nemaska Lithium delivers a second shipment of lithium hydroxide that meets JMBM's final criteria. Nemaska Lithium expects to send the final samples once the lithium hydroxide solution is processed through the crystallizer, which has been received at the Phase 1 Plant and is being commissioned.

"JMBM's encouraging reaction to this first shipment of lithium hydroxide is a clear stamp of approval from a leading cathode material manufacturer for the lithium ion-battery market," said Guy Bourassa, President and CEO of Nemaska Lithium. "I am very pleased with the quality of the lithium hydroxide produced to date given the stage of plant commissioning. The crystallizer technology has been used in the lithium sector for years and no issues are anticipated with this equipment."

Neil Collins, Managing Director of Johnson Matthey Battery Materials commented "We are pleased with the lithium hydroxide solution that we have received to date from Nemaska Lithium. On this basis, we are comfortable to release CAD$2,000,000 of our final milestone payment for the Phase 1 Plant project. As we have said in the past, securing the long-term supply of lithium salts is an important part of our strategy as we continue to grow our Battery Materials business and Nemaska Lithium is a key supplier in that strategy."

Bourassa continued, "Qualifying our products with customers has always been the purpose of the Phase 1 Plant and today we have started to achieve this objective. JMBM has been an excellent partner and customer and I look forward to a long and mutually beneficial relationship with them as we enter the lithium supply chain as a credible and reliable supplier of lithium salts."

About Nemaska Lithium

Nemaska Lithium intends to become a lithium hydroxide and lithium carbonate supplier to the emerging lithium battery market that is largely driven by electric vehicles, cell phones, tablets and other consumer products. The Corporation is developing in Quebec 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 four granted 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.
