The results obtained from these samples confirm the consistency of the grade, the lateral continuity of the spodumene pegmatite as well as the fact the zone remains open laterally. Concerning the exploration campaign conducted in October 2009, we still have to receive the results of the last 3 diamond dill holes, which are expected by the end of December 2009.

The samples have been shipped for preparation (crushing and pulverization) to the lab of Table Jamesienne de Concertation Miniere (TJCM) in Chibougamau. The prepared samples will then be sent by courier to the Lakefield laboratory of SGS Mineral Services in Lakefield, Ontario, for lithium and beryllium analysis. 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, including the insertion of analytical control samples, duplicates and blanks and the follow-up on the results of these assays.
