TORONTO, ONTARIO–( EMWNews – April 7, 2008) – Millstream Mines Ltd. (TSX VENTURE:MLM)(FRANKFURT:NJD) is proud to announce that eleven (11) well defined parallel mineralized zones have been identified by consultants Dave Gamble, P Geo., Edward Bettiol, P. Eng., and Ronald Blais, P. Eng. in their preparations and calculations of Millstream’s Potter Property mineral resources.

To differentiate these multiple zones, with a high degree of confidence, required great patience along with detailed investigation and numerous trial and error runs working in three dimensional (3D) software programs. The use of Datamine’s 3D Modeling and Downhole Explore programs proved very instrumental in illuminating Millstream’s consultant staff of a whole new understanding of this rich “stacked” VMS type deposit encompassing eleven distinct zones of mineralization.

Presently, Millstream’s consultants are finalizing the uncovered database of information and compiling for publication an initial resource estimate under the requirements and guidelines of National Instrument 43-101 on its volcanogenic massive sulphide (VMS) type deposit at its Potter Property. It is expected that this resource estimate will be made ready for public disclosure in the not too distant future.
