12 October 2012

QUEBEC, QUEBEC, CANADA--(Marketwire - Oct. 12, 2012) - Nemaska Lithium Inc. ("Nemaska" or the "Corporation") (TSX VENTURE:NMX) (OTCQX:NMKEF) wishes to provide clarification on the October 2, 2012 press release announcing the results of its preliminary economic assessment on the Whabouchi mine and concentrator and chemical plant. The PEA referenced Proven Reserves of 10.2 MT at 1.53% and Probable Reserves 9.4 Mt at 1.45%. Since this is a PEA report and not a Feasibility Study the company should have classified the resource as In-pit Measured Resources of 10.2 Mt of 1.53% and In-pit Indicated Resources of 9.4 Mt of 1.45%. Mineral resources are not mineral reserves and do not have demonstrated economic viability. All numbers released in the PEA of October 2, 2012 remain unchanged and are not impacted by this change.

The 2012 PEA report will be filed on Sedar within 45 days from the initial press release of October 2, 2012. Nemaska has hired independent consultants Met-Chem Canada Inc. and BBA Inc. to author a feasibility study on mine, concentrator and chemical plant. Reserves will be included in the feasibility study which is due out by the end of December 2012.

The technical information in this press release has been reviewed by Céline M. Charbonneau, Eng. of Met-Chem and Yves Dessureault, Eng. of BBA Inc., qualified persons as defined in National Instrument 43-101.
