Nemaska Exploration Plans the Production of 202,000 Tonnes/Year of Spodumene Concentrate From Its Whabouchi Lithium/Beryllium Deposit

QUEBEC, CANADA--(Marketwire - Jan. 19, 2011) - (TSX VENTURE:NMX)(OTCBB:NMKEF) – NEMASKA EXPLORATION INC. ("Nemaska" or the "Corporation") is pleased to release the results of a National Instrument 43-101 compliant Preliminary Economic Assessment (PEA), on its wholly owned Whabouchi lithium deposit located in the James Bay region, Province of Quebec, Canada.

Preliminary Economic Assessment Highlights
(All calculations assume a price of $280/tonne (FOB Plant) of 6% Li2O spodumene concentrate)
(All figures are quoted in CDN$)*
Open Pit Mine Production   2,950 tonnes per day (1 MT/year)
Average Annual Spodumene Concentrate production   202,000 tonnes of 6 % Li2O
Average Annual Revenue**    $56.6 M
Pre-tax NPV 5% Discount
Pre-tax NPV 8% Discount 
  $184.0 M
$130.3 M
Pre-tax Internal Rate of Return (IRR)    26.6%
Average Operating costs    $27.86 per tonne of ore
Total Initial Capital Costs   $86 M (including $13.4 M contingency and $5 M working capital)
Expected Mine Life   15 years
Pay Back of Capital Costs   3.3 years
* Assuming CDN $ at par with US $
** No credit has been included for a possible beryllium concentrate that can also be produced since metallurgical tests on this specific mineral have yet to be completed.

The PEA contemplates an open pit mining scenario that would annually produce 202,000 tonnes per year of 6% Li2O spodumene concentrate on site.

The spodumene concentrate can be shipped to Asian and European markets from the deep sea port of Saguenay on the Saguenay River, approximately 7 hours drive from the Whabouchi deposit. It is also possible to deliver product to North American markets by railway, approximately 3 hours drive from the deposit.

The PEA was prepared by independent consultants Equapolar Consultants Limited in conjunction with BBA Inc. and Genivar Inc. The complete PEA will be filed on SEDAR within the next 45 days.

Gary Pearse, principal of Equapolar commented, "Based on our preliminary assessment of the Whabouchi deposit we believe the project is economically viable and justifies that the company proceed with a pilot plant and a full feasibility study. This PEA confirms that spodumene concentrate can be economically produced and shipped to end users."

An important use of spodumene concentrate is as a raw material in the production of different lithium products, including battery grade lithium carbonate, lithium hydroxide and lithium metal. Currently, most of the spodumene concentrate transformers are located in China and the majority of the spodumene concentrate supply comes from Australia.

"As demand evolves it becomes more important for end users to secure a geographically diversified supply of spodumene concentrate from producers," commented Guy Bourassa, President and CEO of Nemaska Exploration. "Obviously the province of Quebec represents a highly prospective and prolific location for spodumene. Our goal is to be one of the first to market, producing a high quality spodumene concentrate and we are targeting to complete our feasibility study by year end. The PEA illustrates that our project can be competitive with other producers globally. In addition, we are also studying the possibility of building our own lithium production facility in Quebec and transforming the spodumene concentrate into lithium products including lithium carbonate."

Mr. Bourassa will attend this year's Vancouver Resource Investment Conference. He will be available to update current and prospective shareholders on the Company's latest achievements. Nemaska will be exhibiting at booth 1030 at the Vancouver Convention Centre - West Exhibit Halls B & C on January 23-24, 2011.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. The preliminary assessment includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary assessment will be realized.
