Nemaska Blasts a 50 Tonnes Bulk Sample at Whabouchi Lithium Project for Pilot Plant Testing

QUEBEC CITY, QUEBEC--(Marketwire - May 5, 2011) - Nemaska Exploration Inc. («Nemaska» or the «Corporation») (TSX VENTURE:NMX) (OTCBB:NMKEF) (FRANKFURT:NOT) is pleased to announce that it has blasted a 50 tonnes bulk sample on its Whabouchi lithium project for metallurgical pilot plant testing. The 50 tonnes sample comes from the main zone and is located in the R-575 trench where channel samples returned 1,65% Li2O over 37,5 metres (see press release February 8th, 2011). In addition to the material coming from the R-575 trench, the bulk sample will also include approximately 8 tonnes of drill core material that has been collected across the deposit as part of the recently completed 8,909 metre infill diamond drill program. The diamond drill program used large-diameter HQ size core to obtain more representative material for the pilot plant process.

The goal of the program is to produce a representative sample that will be used to feed a pilot plant to be done at SGS Lakefield facilities in Ontario. An optimized flow sheet from the initial bench scale tests conducted in fall 2010 (see press releases September 8th, and November 23rd, 2010) will be used to set up the pilot plant for running approximately 58 tonnes of ore throughput for production plant design. The program will also produce the engineering data for the metallurgical portion of the feasibility study and plant design phase. The pilot plant testing is scheduled to commence by the end of May. The spodumene concentrate, lithium carbonate and lithium hydroxide, produced from the pilot plant test will be used as commercial samples in Nemaska's on-going global marketing.

"This is a major step towards completing a full feasibility study and discussing offtake agreements with potential clients," commented Guy Bourassa, President and CEO of Nemaska Exploration. "We remain on track to have the definitive feasibility study completed by Fall 2011."
