QUEBEC CITY, QUEBEC--(Marketwire - March 4, 2011) - (TSX VENTURE:NMX)(OTCBB:NMKEF)(FRANKFURT:NOT) NEMASKA EXPLORATION INC. ("Nemaska" or the "Corporation") is pleased to announce that it has closed, under escrow, a $3.7 million private placement with an absolute controlled subsidiary of Chengdu Tianqi Industry Group Co., Ltd. ("Tianqi Group" or "Tianqi"). Tianqi Group is the parent company of Sichuan Tianqi Lithium Industries Inc., the largest lithium battery material provider in China that uses ore (spodumene concentrate) as its raw material to produce, among other products, lithium carbonate. Through its subsidiaries, Tianqi has captured a significant share of the Chinese lithium market and forged long-term relationships with the majority of Chinese battery manufacturers. Simultaneously they have created an international sales network covering multiple countries, in a proactive move to expand outside China in anticipation of the growing demand for lithium batteries.

"Our team conducted extensive due diligence on Nemaska before making our investment decision and our geologist and lithium experts were very pleased with the drilling, metallurgy and technical reporting done by Nemaska to date," commented Vivian Wu, Vice President of Corporate Development of Tianqi Group. "Our customers have communicated an increasing demand for our lithium products and accordingly we sought to diversify our supply. As with our customers, we build long term relationships with our suppliers and we view this investment as a first step in strategic supply discussions with Nemaska as it progresses towards becoming a spodumene concentrate producer."

Guy Bourassa, President and CEO of Nemaska Exploration, said "With this investment, Tianqi now holds 10% of all of the issued and outstanding shares of Nemaska, a significant position in the Corporation and a validation of our business plan to be first to market with new production. We look forward to a long and productive relationship."

Under the terms of the subscription agreement previously announced on January 4, 2011, the absolute controlled subsidiary of Tianqi will receive 7,370,468 common shares (the "Shares") of Nemaska at a price of $0.50 per Share and 4,963,050 share purchase warrants (the "Warrants") for aggregate gross proceeds of $3,685,234 (the "Private Placement"). Each Warrant entitles its holder to purchase until March 5, 2012, one additional Share at an exercise price of $0.61 per Share. The TSX Venture Exchange (the "Exchange") has conditionally approved the Private Placement. The securities to be issued will be subject to a hold period of 4 months plus one day in Canada. Following closing of the Private Placement, Tianqi will indirectly become an insider of the Corporation. Therefore, the Private Placement has been completed in escrow, subject to the confirmation of the suitability of Tianqi's insiders by the Exchange, which is expected within the next three weeks.

Dundee Securities Corporation acted as the sole agent in this Private Placement and will receive a cash commission equal to 4.5% of the gross proceeds of the Private Placement and compensation warrants equal to 4.5 % of the Shares, each such warrant entitling it to purchase, until March 5, 2011, one additional Share at an exercise price of $0.50 per Share.
