(Nemaska) is very proud to announce the signing today of an option agreement to purchase 100 % of the Lac Levac and Lac des Montagnes mining properties (the Properties) from Golden Goose Resources Inc. (Golden Goose : GGR.V). Nemaska has paid a non refundable amount of $150,000 to obtain said option. The Properties are comprised of 594 cells, covering about 32,000 hectares and extend about 65 km over the Lac des Montagnes Formation, a recognized green belt polymetallic volcano sedimentary formation. In particular, the Lac Levac property holds the Nisk-1 deposit, for which mineral resources were published and confirmed in a 43-101 report signed in June 2008 by RSW Inc. The complete report is available at the following internet address: http://www.goldengooseres.com/medias/docs/pdf/Levac_43101_Ang.pdf The resources published are: /T/ ----------------------------------------------------------------- Tonnes % Ni % Cu % Co g/t Pd g/t Pt ----------------------------------------------------------------- Measured 1,255,000 1.09 0.56 0.07 1.11 0.20 ----------------------------------------------------------------- Indicated 783,000 1.0 0.53 0.06 0.91 0.29 ----------------------------------------------------------------- Inferred 1,053,000 0.81 0.32 0.06 1.06 0.50 ----------------------------------------------------------------- /T/ Many information, photos and maps concerning the Lac Levac project are available at the following internet address: http://www.goldengooseres.com/pages/en/project/levac/ To exercise the option and acquire the Properties, Nemaska shall pay, at the latest, December 31, 2009, an amount of $2,000,000 and issue $850,000 in shares of Nemaska at the price of its Initial Public Offering (IPO), planned for 2009 fall. Nemaska will also grant one warrant per share issued, each warrant entitling Golden Goose to purchase one share at a 20% premium over the IPO price for two years. Golden Goose will also appoint a representative to the board of Nemaska and will retain a 2% net smelter royalty ("NSR"), of which 1% NSR can be repurchased by Nemaska for $1,000,000 within the first three years. The transaction is subject to the approval of the TSX Venture Exchange and to other standard conditions. Nemaska Exploration Inc., a reporting issuer in Quebec since November 2008, is a mineral exploration company involved in the James Bay region in Quebec. Its main asset is the Lac Arques property, 100 % owned, covering about 45 km of the Lac des Montagnes Formation. The Lac Arques, Lac Levac and Lac des Montagnes properties, are easily accessible by the Route du Nord and are located about 250 km North of Chibougamau and in the vicinity of the town of Nemaska. According to Guy Bourassa, President and CEO "The acquisition of the Properties will allow Nemaska to speed-up its development plan by at least 3 years. In fact, the identification of mineral resources as the one calculated on the Nisk-1 deposit not only require important works, but mainly time." He also added: "This acquisition is important not only for the Nisk-1 deposit, but for the important E.M and MAG anomalies overlapping the Lac Arques and Lac Levac properties and extending within the Lac Arques property to the West and the East".
