Nemaska Lithium Commissions PEA for Lithium Hydroxide Plant in Quebec

QUEBEC CITY, CANADA--(Marketwire - April 26, 2012) - Nemaska Lithium Inc. ("Nemaska" or "the Corporation") (TSX VENTURE:NMX)(OTCQX:NMKEF) is pleased to announce the commissioning of a Preliminary Economic Assessment (PEA) for the development of a lithium chemical complex in the Province of Quebec. The Corporation's decision to proceed with the PEA is based on the positive results of its multi-phase pilot program for the chemical transformation of spodumene concentrate to battery grade lithium hydroxide and lithium carbonate, as described in the March 19^th press release. This second phase transformation facility is fundamental to Nemaska's strategy of meeting the ever-increasing demand for lithium hydroxide, a premium product required by international battery markets.

"Nemaska's strategy is to position the Corporation to become a world leading producer of lithium hydroxide for batteries, and to maximize value for our shareholders as well as for Quebec-based communities," said Guy Bourassa, President and Chief Executive Officer of Nemaska. "Quebec will be home to the only facility outside of China capable of achieving this value-added transformation and availing international buyers, specifically North American and European customers, to this premium product."

Technical support from our strategic partner Chengdu Tianqi Industry Group/Tianqi Lithium will facilitate the implementation of this unique process as well as assist with the development of highly competent local engineers. The Corporation remains confident that it will meet its previously announced timeline to put the Whabouchi deposit into production and begin producing a spodumene concentrate by the fourth quarter of 2013. The construction of the lithium hydroxide processing facility is scheduled to be completed in 2014.

Nemaska has selected Met-chem Canada Inc. to carry out the PEA study, with results expected for publication in the third quarter 2012. The PEA will contemplate the refining metallurgical processing facilities to transform spodumene concentrate into lithium hydroxide and carbonate as well as the capital expenditures associated with the construction of this state of the art chemical transformation plant. Nemaska is currently considering the optimal location for the facility within the Province of Quebec. The location of the facility will be determined prior to the publication of the PEA results. In parallel, the Corporation is advancing the Definitive Feasibility Study on the construction of a spodumene concentrate facility and mine, which is also scheduled for publication in the third quarter of 2012.
