Nemaska Continues to Report Wide High-Grade Intersections from Whabouchi Lithium Project

11 April 2011

QUEBEC CITY, QUEBEC--(Marketwire - April 11, 2011) - Nemaska Exploration Inc. ("Nemaska" or the "Corporation") (TSX VENTURE:NMX) (OTCBB:NMKEF) (FRANKFURT:NOT) is pleased to announce further results from 5 additional holes of its drill program recently completed on its 100% owned Whabouchi project. In total 8,633 metres have been drilled in 41 holes. The results continue to illustrate the width and high-grade of the main mineralized zone. Highlights include: 45.9 m at 2.13% Li2O, 85.0 m at 1.69% Li2O and 63.8 m at 1.44% Li2O.

"These results are part of our in-fill drill program, aimed at upgrading our existing resource as we move our project towards the feasibility stage," commented Mr. Guy Bourassa, President and CEO. "We expect to have a steady flow of results to report to the market over the next months with a goal of having an updated resource estimate out by end of May."

The intersections from the next 5 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 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.
