ADEX REPORTS FINAL PHASE 1 RESULTS FOR NORTH ZONE AT MOUNT PLEASANT

Toronto ? September 18, 2008 ? Adex Mining Inc. (?Adex? or the ?Company?) (TSX-V: ADE) is pleased to announce the final analytical results for the North Zone (?NZ?) Phase 1 definition drilling program at its Mount Pleasant Mine Property in southwestern New Brunswick, Canada. The results are for sampled core from 2,718 metres of drilling over eight vertical holes that tested the Property?s Deep Tin and North Adit mineralized bodies within the NZ. 

Summary analyses for NZ Holes AM-08-01 to AM-08-07 and Hole AM-08-10 are listed as follows:

Holes AM-08-01 to AM-08-04, AM-08-06, AM-08-07 and AM-08-10 were drilled to better delineate the NZ as part of Adex?s National Instrument 43-101 (?NI 43-101?) compliant evaluation of its NZ tin-indium-zinc-copper (Sn-In-Zn-Cu) zones.  Hole AM-08-05 was drilled to only 127 metres as a twin hole of Hole AM-08-04 and Hole AM-08-10 was drilled as a twin hole of historical Hole E-8. The analytical results from these holes were found to be comparable with their twins.

The results of the Phase 1 definition drilling program were either consistent with or better than the expectations of management of Adex. Specifically, in the NZ, Sn-In-Zn and tungsten-molybdenum (WO₃-MoS₂) bearing mineralization was found to occur and extend to shallower depths than expected, as indicated in the analytical results reported from Holes AM-08-01, AM-08-02, AM-08-03 and AM-08-04. 

The Phase 2 drill program, designed to expand the size of the mineral resources at the NZ, has now been completed. The drill results, once available, will allow for a better understanding of the lateral extent of the North Adit mineralization to the north, west and east of Holes AM-08-01 and AM-08-02, and the Deep Tin mineralization to the south, southwest and southeast of Holes AM-08-03 and AM-08-04. Analytical results are pending from the Phase 2 exploration drill program.

The nature of the geological setting of the Mount Pleasant mineralized bodies hosted within and along the contacts of granite bodies and breccias results in highly variable shapes and orientations of its zones. For this reason, no estimation of true widths can be provided from these results at this stage.  Besides the exploration drilling, an extensive program of additional splitting and sampling of historical core plus the completion of missing indium analyses for sample pulps and split core stored on the property is continuing in order to better define the shape and extent of these bodies. Analyses remain pending for much of this work and will be summarized in separate news releases. 

The 2008 drilling program is part of an ongoing review of the Mount Pleasant Mine Property with the purpose of completing an independent NI 43-101-compliant evaluation of the NZ. The results of this drilling program and the additional sampling of historical core in the vicinity of these holes are being compiled and incorporated into Adex?s GEMCOM database with the purpose of generating an NI 43-101 compliant deposit model and resource estimate for the NZ mineralized bodies.

The historical, non-NI 43-101 compliant total ?resource? at the NZ and the Deep Tin Zone consists of 3,645,429 tonnes of 0.80wt.% (weight percent) tin, 107 ppm (107 g/t) indium, 0.87wt.% zinc and 0.19wt.% copper, based on a 1997 feasibility study completed by Kvaerner Metals Davy Ltd.  These historical estimates were prepared prior to the implementation of NI 43-101. A qualified person has not done sufficient work to classify these historical estimates according to NI 43-101 standards or the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards and Adex is not treating these historical estimates as current mineral resources as defined in NI 43-101.  They are presented because Adex considers them to be relevant and of historic significance.  These historical estimates should not be relied on.

Additional information concerning the Mount Pleasant Mine Property is contained in the NI 43-101 compliant Technical Review of the Mount Pleasant Property, Including a Mineral Resource Estimate for the Fire Tower Zone Southwestern New Brunswick dated August 1, 2006 completed by Paul Dunbar, M.Sc., P.Geo., Senior Associate Geologist, Andrew Hara, P.Eng., Senior Associate Mining Engineer, Robert de l?Etoile, M.Sc., P.Eng., Senior Associate Engineer, and Dorota A.

Quality Assurance/Quality Control

Adex Mining has implemented an industry standard QA/QC program. Core is split in half using a hydraulic core splitter, sealed in secure packages and shipped by bonded carrier to S.G.S. Laboratories in Toronto for analysis using sodium peroxide fusion with ICP-MS finish for indium and ICP-OES finish for tungsten, molybdenum, tin, bismuth, arsenic, zinc, copper and lead. A pulp duplicate unknown to the laboratory is submitted per batch of 10 samples and sent to a second laboratory, while a polymetallic standard unknown to the laboratory is included with each shipment of duplicate samples. S.G.S. fulfills standard QA/QC protocols.

Qualified Person

The Mount Pleasant exploration program is being conducted under the direction of Trevor Boyd, P.Geo., the company?s independent Geological Consultant and a qualified person as defined by National Instrument 43-101. Mr. Boyd supervised the preparation of the technical information contained in this press release in compliance with NI 43-101.
