ADE Adex Mining Inc

Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE: ADE) is pleased to announce that SGS Lakefield Research Limited ("SGS") of Lakefield, Ontario has been engaged to test the hydrometallurgical treatment of molybdenum concentrate from the Fire Tower Zone ("FTZ") at Adex' wholly-owned Mount Pleasant Mine Property ("Mount Pleasant" or the "Property") located in southwestern New Brunswick, Canada.

Adex has engaged SGS to perform a scoping level investigation of a hydrometallurgical flowsheet that is designed to allow Adex to produce high grade ammonium molybdate at its Mount Pleasant operations. The process involves pressure oxidation of the molybdenite to convert the sulphide concentrate to an oxide, followed by an atmospheric ammonia leach of the molybdenum trioxide product. Ammonium dimolybdate crystals are then recovered from the ammonia leach liquor by evaporation and crystallization.

Results from test work, expected in about six weeks, will, if positive, lead to an upgrade to the conceptual framework related to the production of tungsten and molybdenum products as described in the 2008 FTZ Scoping Study completed by Aker Metals, a division of Aker Solutions Canada Inc., which indicated a pre-tax internal rate of return ("IRR") of 27% for the production of ammonium paratungstate ("APT") and molybdenum sulphide concentrate, based on projected product prices for APT of $US215 per metric tonne unit and for molybdic oxide (MoO3) of US$23.17 per pound. An executive summary of the 2008 Scoping Study is contained in the National Instrument 43-101 ("NI 43-101") compliant technical report (the "Technical Report") on the Fire Tower Zone ("FTZ") entitled "A Technical Review of the Mount Pleasant Property, Including an updated Mineral Resource Estimate on the Fire Tower Zone, Southwestern New Brunswick for Adex Mining Inc." dated December 1, 2008 and completed by Paul Dunbar, M.Sc., P.Geo. Senior Associate Geologist of Watts, Griffis and McOuat Limited, Dorota A. El-Rassi, M.Sc., P.Eng., Geological Engineer of SRK Consulting and John S. Rogers, P.Eng., of Aker Metals, a division of Aker Solutions Canada Inc., which is available on www.sedar.com.

Errol Farr, the President and CEO of Adex, stated, "This investigation, while preliminary in nature, is another step toward evaluating the re-commencement of mining the FTZ. With metal prices, especially for molybdenum, showing recovery in 2010, the FTZ is demanding new attention by Adex management." It is the goal of Adex to produce value added products with each of the mineral concentrates which may ultimately be processed at Mount Pleasant.

The 2008 FTZ Scoping Study and the economic analyses contained therein are preliminary in nature and contain "Inferred" mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the results of the 2008 FTZ Scoping Study will be realized with more detailed work. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Adex is currently engaged in bench and pilot metallurgical test programs for the production of tin concentrate and value added zinc and indium metal products from its Mount Pleasant North Zone ("NZ") resource, as discussed in a press release dated March 3, 2010. Adex intends to make a production decision on the NZ in 2010 pending completion of a definitive feasibility study scheduled for forth quarter of this year.

The Property hosts two important and separate mineral resources, being the tungsten-molybdenum bearing FTZ and the tin-indium-zinc bearing NZ. The FTZ is the site of a past-producing tungsten-molybdenum underground mining operation that produced and sold tungsten concentrate between 1983 and 1985.
