Adex Mining Inc. Announces Metallurgical Test Program for Mount Pleasant Mine Property

TORONTO, ONTARIO--(Marketwire - Sept. 26, 2007) - Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE:ADE) is pleased to announce its metallurgical testing plans for the development of its Mount Pleasant Mine Property (the "Property") located in southwestern New Brunswick.

Further to the Company's announcement on August 21, 2007 that it was developing a metallurgical process for the production of tungsten and molybdenum from the Property's Fire Tower Zone and the production of tin and indium from the Property's North Zone, the Company has now identified such process. Various test programs have been completed over the last fifteen years to assess alternative process technologies, to improve on product purity and for the optimization of metal recovery. A fully integrated process flowsheet capable of processing ore from various zones of the Property has been defined and will be subjected to an extensive optimization test program over the next year as a precursor to feasibility studies for commercial production at the Property.

The refinement of the process flowsheet will focus on the use of gravity separation, flotation and magnetic separation for the production of tungsten, tin, bulk-sulfide and molybdenum concentrates. Added value products such as ammonium paratungstate and indium metal will be produced from respective low-grade tungsten and bulk-sulfide concentrates. Hydrometallurgical processing technologies have also been identified to optimize the purity of the metal products proposed to be produced from the Property for use by high-value steel and electronics industries.

The metallurgical test program will be completed in phases and the initial phase has been initiated to include bench-scale testing of ore grinding, physical upgrading of the ore and hydrometallurgical treatment of concentrates. Subsequent-phase testing of the metallurgical flowsheet will included extensive grinding optimization and pilot scale upgrading / hydrometallurgical flowsheet trials including characterization of the flowsheet on ore from the various ore zones.

Large bulk samples of ore taken from each ore zone during previous operations will be used for the initial-phase metallurgical testing. Measures to obtain additional bulk samples for each phase of the metallurgical program are under review. The final-phase ore-body-characterization tests will utilize ore from the drill program (a drill program for North Zone and the Fire Tower zone is also planned to commence in the early winter of 2007-08). The final-phase tests will assess the flowsheet's ability to handle the variability of ore within each zone and will further optimize on the process operating parameters. The ore-body-characterization testing is intended to improve the processing of ore of diverse compositions and is also defined as a "process intensification test program" to achieve optimum commercial benefit from the proposed process flowsheet.

In addition to the management of a metallurgical test program to assure optimum product quality and compliance with world market specifications, the Company will be developing a fully integrated process system to be designed to exceed environmental guidelines. The overall process technology for the Property has been selected to optimize on the recovery of metals and to minimize environmental impact with provisions to reduce waste generation, recycle water and employ proven wastewater treatment technologies. Various water treatment technologies are presently undergoing bench-scale pilot tests to assure optimum water and wastewater quality.
