Nemaska Exploration Samples up to 18.35 g/t Gold, 17.65% Copper, 115 g/t Silver and 4.87% Ni From Duval Showings (Lac des Montagnes Property)

QUEBEC CITY, QUEBEC--(Marketwire - Aug. 25, 2010) - Nemaska Exploration Inc. ("Nemaska" or the "Company") (TSX VENTURE:NMX) is pleased to announce grab sample results obtained from the Duval Showings which are located on Nemaska's 100% owned 60,000 hectare property that hosts the polymetallic Lac des Montagnes formation in northern Québec, Canada. The Duval showings are approximately 9 km southeast of Nemaska's Whabouchi (lithium/beryllium) project.

Mr. Guy Bourassa, President and CEO of Nemaska commented, "We are very pleased with these first results which we believe establish the excellent potential of this area. Based on what we have seen to date, more work, including drilling, is planned for the fall. Additional samples taken during the month of August have been sent to the laboratory for analysis and we expect results in September."

The Duval Showings are situated in a zone of disseminated to semi-massive sulphides which were identified during a field work program at the beginning of the summer. Nemaska undertook an extensive prospecting and sampling program which is being followed up by geophysics, stripping and channel sampling. To date the Duval zone has been identified for more than 450 m along strike.The mineralisation occurs within of a band of 40 to 60 m of pyroxenite and sheared and altered gabbro, between peridotite to the North and pegmatite to the South.

The best results from the Duval sampling program are as follows:

During the month of August, 3 trenches totalling 224 m were done in order to do channel samples. In September, the Company plans to complete 15 additional trenches totalling approximately 900 m. This work will be followed by a first phase of diamond drilling. The Duval zone is situated roughly 3 km to the east of the Valiquette showing which historically reported grab samples of up to 2.23% Ni and 1.42% Cu. Nemaska also plans to conduct diamond drilling of the Valiquette showing this fall.

The technical sections of this press release have been prepared by Mr. Yvan Bussières, P. Eng, qualified person as defined in National instrument 43-101.

The samples have been shipped for preparation (crushing and pulverization) to the Table Jamésienne de Concertation Minière (TJCM) lab in Chibougamau. The prepared samples are then sent to ALS Chemex laboratory in Val D'Or for analysis according to the ME-ICP61 and PGM-ICP23 methods. This laboratory is recognized by industry and accredited ISO/MEC 17025: 2005 by the Canadian Council of standards. Nemaska Exploration implements a rigorous quality control protocol to its operations. For the grab samples, the quality control is the one used by the laboratory which includes the insertion of analytical control samples, duplicates and blanks and follow-up on the results of these assays.
