Nemaska Lithium Whabouchi Feasibility Study Shows NPV of $924M and IRR of 25.2%

QUEBEC CITY, QUEBEC--(Marketwired - May 13, 2014) - Nemaska Lithium Inc. («Nemaska» or the «Corporation») (TSX VENTURE:NMX)(OTCQX:NMKEF) announces the results of a positive Feasibility Study on the Whabouchi Mine and Concentrator to be located in the lower James Bay Region of Quebec and the Hydromet Plant to be located in Salaberry-de-Valleyfield, Quebec.

The Feasibility Study encompasses a combined open pit and underground mine plan and was prepared by Met-Chem Canada Inc. (Met-Chem) with contributions from Michel Bilodeau, Eng., M. Sc. (App.), Ph.D. for the cash flow model. Additional technical elements of the study have been authored by Mr. Warren Wolfs of Noram Engineering & Construction Ltd., Dr Peter G. Symons, Manager R&D of Electrosynthesis Company Inc., Mr. Gary Pearse, M.Sc., P. Eng. of Equapolar Research and Simon Thibault, M.Sc. bio. of the Roche Group. A Mineral Reserve has been declared by Met-Chem based on an updated Mineral Resource estimate completed by Jean-Philippe Paiement, M.Sc. P.Geo., of SGS Canada Inc. - Geostat ("SGS Geostat") on January 28, 2014 of the Mineral Resource estimate prepared by André Laferrière, M.Sc. P.Geo., of SGS Geostat with an effective date of June 6, 2011. Nemaska will host a conference call on the Feasibility Study on Wednesday, May 14, 2014 at 10 am Eastern Standard Time. Conference call details are found at the end of this press release.

The Feasibility Study positively compares to the Preliminary Economic Assessment filed on Sedar on November 16, 2012 on a number of fronts:

"We are very pleased with the significant improvements in the NPV and IRR for this project," commented Guy Bourassa, President and CEO of Nemaska Lithium. "We extended the mine life by 8 years while keeping the CAPEX on the project to within 15% of the figures reported in 2012 when one takes exchange rate changes and inflation into consideration. We were able to achieve this while significantly reducing the overall footprint of the project and reducing the environmental impact of the mine site."

Mineral Resources and Mineral Reserves

The Mineral Resources were estimated by Jean-Philippe Paiement, M.Sc. P.Geo., of SGS Geostat with an effective date of January 22, 2014, updating the past Mineral Resource estimate prepared by André Laferrière, M.Sc. P.Geo., of SGS Geostat with an effective date of June 6, 2011. The Mineral Resources were estimated based on the following geological and resources block modeling parameters which are based on the Memorandum received from SGS Geostat, dated January 22, 2014:

• Mineral resources were evaluated from the diamond drill holes and channels analytical results completed by Nemaska since 2009. Historical drill holes and channels were not used for the current mineral resources estimate. A total of 479 drill holes/channels and 9,358 assays were used for the mineral resources model.
• The mineral resources 3-D modeling of mineralized pegmatite dyke was conducted using a minimal modeling grade of 0.50% Li₂O over a 2m horizontal thickness.
• The interpolation was conducted using composited assays of 2m in length. The Mineral Resources were modeled and estimated using Genesis© software.
• Block Model Interpolation was done using Ordinary Kriging. The block model was defined by a block size of 5m long by 3m wide by 5m thick and covers a strike length of 1,315 m to a maximal depth of 520 m below surface.
• The In-pit Mineral Resources were limited inside an optimized pit shell. The interpolated blocks of the model located below the optimised pit shell are not included in the updated Mineral Resources. The In-pit Mineral Resources reach 320 m below surface (maximum depth of optimised pit).
• The cut-off grade of the reported Mineral Resources is 0.43% Li₂O.

*Note: The mineral resources estimate has been calculated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definitions Standards for mineral resources in concordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects. Mineral resources which are not mineral reserves do not have demonstrated economic viability. Inferred mineral resources are exclusive of the Measured and Indicated resources.

Bulk density of 2.70 t/m³ is used. Effective date January 22, 2014. * Rounded to the nearest thousand.

The Mineral Reserve estimate was prepared by Met-Chem, using the updated Mineral Resource block model. The Mineral Reserves are included in the Measured and Indicated Mineral Resources that have been identified as being economically extractable and which incorporate mining losses and the addition of waste dilution.

Reserves categories are compliant with Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definitions Standards for mineral resources in concordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects. The cut-off grade for the open pit Mineral Reserves Li₂O ≥ 0.43% and the cut-off grade for the underground Mineral Reserves is Li₂O ≥ 0.80%. The effective date of the Mineral Reserves estimate is May 13, 2014. * Rounded to the nearest thousand.

Mine and Hydromet Plant Plan

The Feasibility Study outlines a combined open pit and underground mine. The open pit mine Proven and Probable Reserves are 20 million tonnes at 1.53% Li₂O. The underground mine Proven and Probable Reserves are 7.3 million tonnes at 1.28% Li₂O.

During the first 20 years, production will be derived from an open-pit developed to a maximum depth of 190 meters and with an average strip ratio of 2.2 to 1. The open pit will be mined using a standard fleet of off-road mining trucks and hydraulic excavators at a rate of 2,740 tonnes of ore per day.

During the last 6 years, production will be derived from an underground operation at 3,342 tonnes per day and accessed via a ramp within the open pit. The underground development will reach an average depth of 90 metres below the pit bottom. The selected underground mining method is longhole stoping with the crown pillar below the pit recovered at the end of the mine life.

A formal production decision is expected to be made following, among other things, the receipt of Certificates of Authorization from the relevant Québec and Federal Government regulatory authorities. The project development schedule assumes that the General Certificate of Authorization for the project will be granted on or before March 31, 2015 and that concurrently the Project financing will have been completed. On site, power requirements at the mine are expected to average 5 MW during operations and will be provided by a 25 kV power line connecting Whabouchi to the nearby Poste Albanel hydro-electric power station.

The hydromet plant will be located in Salaberry-de-Valleyfield, QC Perron Industrial and Port Park. This site has been selected for its excellent infrastructure. The Park is serviced by two railway systems for both Canada and the USA, a major port and a pool of skilled workers from the Montreal area. The hydromet plant will be state of the art and will use Nemaska's proprietary process to convert the spodumene concentrate into the purest lithium hydroxide on the market. Proximity to the Hydro-Quebec network, as the plant will use close to 50 MW once in full operation, and access to the natural gas network were also deciding factors.

Bourassa continued, "It is important to review the results of this Feasibility Study on a number of levels. First, the cost of our spodumene concentrate FOB mine site of $189/t compares very favorably to our competitors globally. Second, the physical characteristics of the Whabouchi ore body are homogenous, having low sodium, low potassium and low mica content. These impurities are known to cause issues and add costs during the production of spodumene concentrate and high-purity battery grade lithium carbonate or hydroxide. This is NOT a problem for Nemaska."

"Our lithium hydroxide cost of $3,450/t (US $3,105/t) is competitive with any supplier of lithium hydroxide today and in the foreseeable future," Mr. Bourassa stated. "Our new flow sheet has been designed to optimize the production of lithium hydroxide, while also producing a high purity lithium carbonate (99.99%) as a by-product at an average cost of $4,190/t (US $3,771/t). Nemaska's market penetration and growth strategy is to become an important supplier of lithium hydroxide by offering the highest quality product at competitive prices, while maintaining healthy margins. In tandem, Nemaska plans to grow its target market through converting lithium carbonate users to lithium hydroxide by offering a superior product (lithium hydroxide)."

Market Analysis

"The lithium battery market is driven largely by demand from the transportation sector, precipitated by air quality and climate change issues," commented Mr. Bourassa. "The U.S. White House recently issued the third U.S. National Climate Assessment update which said evidence of human-made climate change "continues to strengthen" and that "Americans are noticing changes all around them."

The third U.S. National Climate Change Report went on to say that "planning for adaptation (to address and prepare for impacts) and mitigation (to reduce future climate change, for example by cutting emissions) is becoming more widespread, but current implementation efforts are insufficient to avoid increasingly negative social, environmental, and economic consequences."

Mr. Bourassa continued, "The report from the Obama Administration supports our vision of wide spread deployment and adoption of electric vehicles and the lithium-ion batteries that power them." Mr. Bourassa went on to say, "To answer that demand, Tesla Motors recently announced its decision to build a lithium-ion battery Gigafactory. This was a major boost to the lithium-ion battery market and positively impacted the entire downstream supply chain. Like Tesla, Nemaska is on the cutting edge of its industry with ambitious plans to provide the highest purity lithium hydroxide at the lowest cost. Just as Tesla is changing the standard for electric vehicles Nemaska is changing the standard for lithium-ion batteries."

To complete the Feasibility Study, Nemaska commissioned signumBOX Inteligencia de Mercados, an independent market analysis group based in Chile, to produce a Lithium Carbonate and Lithium Hydroxide Market Study. The market study contemplates existing lithium compound suppliers, their planned growth and new suppliers to market as well as anticipated demand forecast into 2025. The study showed that unlike lithium carbonate, the lithium hydroxide market is expected to tighten as growth in demand, driven largely by batteries, will not be satisfied by the increases in current installed capacity.

The study concludes the situation will be aggravated towards the end of the decade when the growth in demand will be greater than the growth in supply. Newcomers to the market, such as Nemaska, will fill this gap in supply and demand. The study also shows the price of lithium hydroxide will increase from US $7,100/t in 2013 to US $8,000/t in 2017 to US $11,100/t by 2025. By contrast, Lithium carbonate prices will range from US $5,700/t in 2013 to US $5,000/t in 2017 to US $8,400/t by 2025.

Lithium hydroxide is emerging as the chemical compound of choice for the growing lithium-ion battery market due to several factors including: a longer life cycle; better power density (last longer between charges) and enhanced safety features (more tolerant to temperature changes, especially high heat).
