QUEBEC CITY, QUEBEC--(Marketwire - April 27, 2011) - Nemaska Exploration Inc. ("Nemaska") or the "Corporation"), (TSX VENTURE:NMX) (OTCBB:NMKEF) (FRANKFURT:NOT) is pleased to report the results from 10 additional holes of its drill program recently completed on its 100% owned Whabouchi project. In total 8,909 metres have been drilled in 43 holes. The results continue to illustrate the high-grade nature of the main mineralized zone and confirm the presence of smaller dykes to the South of the Main zone. Highlights include: 53.5 m at 1.81% Li2O, 39.6 m at 1.56% Li2O, 13.5 m at 1.81% Li2O and 17.0 m at 1.71% Li2O. The results of the initial 22 holes have been released on March 24, April 11 and 20, 2011.

The intersections equal to or greater than 5 m from 10 holes are as follows:

The Company has reported the intersection lengths as well as the best estimates of the true widths given the current understanding of the geology. The drill holes were done at an average azimuth of 330 degrees and a dip of 50 degrees. The pegmatite bands have generally an azimuth of 060 degrees and a South-East dip of 70 degrees to 80 degrees.

All samples have been shipped to the Table Jamésienne de Concertation Minière ("TJCM") in Chibougamau, Quebec, for preparation process: inventory, drying, weigh, crushing, split and pulverization. The pulverized portions were then sent by secured courier to either the laboratory of SGS Mineral Services in Don Mills, Ontario ("SGS"), or to the ALS Chemex facilities in North Vancouver, British-Colombia ("ALS"), for lithium, beryllium and rubidium analysis by Inductively Coupled Plasma methods. These laboratories are recognized by the industry and accredited ISO/MEC 17025 by the Standards Council of Canada. In addition to the quality assurance and quality control ("QA/QC") employed by SGS and ALS, Nemaska Exploration develops a rigorous QA/QC protocol for its operators, including the insertion of analytical standard samples, duplicates and coarse silica blanks on a systematic basis. To determine the QC warning, ±2x Std. Dev., and QC failure ±3x Std. Dev. were used. QC results did not highlight any significant analytical bias.
