ADEX DRILL RESULTS INCLUDE ADDITIONAL HIGH-GRADE INDIUM-ZINC INTERSECTIONS AT MOUNT PLEASANT

Toronto ? July 31, 2008 ? Adex Mining Inc. (?Adex? or the ?Company?) (TSX-V: ADE) is pleased to announce results from the fourth, sixth and seventh holes (AM-08-04, AM-08-06 and AM-08-07) of its 2008 diamond drill program at the Mount Pleasant Mine Property in southwestern New Brunswick, Canada. In addition, Adex announces that updated results from the re-assay of four samples of over-limit indium (greater than 1,000 parts per million (?ppm?)) in previously announced hole AM-08-03 are now available.  The results for these four vertical holes, from sampled core intersecting the property?s Deep Tin Zone, include a number of significant indium readings. 

?Adex?s 2008 drill testing program at Mount Pleasant is continuing to yield encouraging results,? said Kabir Ahmed, President and CEO of Adex Mining. ?This work will be instrumental to us in preparing updated mineral resource estimates for Mount Pleasant, which in turn represents an important step in fast-tracking the project to the feasibility stage of development.?

Results from hole AM-08-03 have been revised upwards to indicate that the hole?s 198-metre intersection from 12 to 210 metres down hole previously announced in the Company?s press release dated July 7, 2008 now contains an average grade of 258 grams per tonne (g/t) indium, with the 18-metre contained interval 63 to 81 metres down hole containing 1,920 g/t indium.

Results from holes AM-08-04 and AM-08-07 include two samples each of over-limit indium (greater than 1,000 ppm). These samples are undergoing re-assay that will result in an upward revision in indium contents for these holes. 

Detailed results for holes AM-08-03, AM-08-04, AM-08-06 and AM-08-07 are as follows:

AM-08-03, AM-08-04, AM-08-06 and AM-08-07 are definition holes drilled as part of Adex?s National Instrument 43-101 (?NI 43-101?)-compliant evaluation of its tin-indium-zinc-copper bearing North and Deep Tin Zones. These holes are particularly encouraging because the results to date appear to suggest the mineralization associated with the Deep Tin Zone (non-NI 43-101 compliant) manifests towards the surface.  A drill has been moved to the target area to conduct additional follow-up testing based on these results. The historical, non-NI 43-101 compliant total ?resource? at the North and Deep Tin Zones 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.

The historical estimates presented above with respect to the North Zone and the Deep Tin Zone 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.

The nature of the geological setting of the North Zone?s mineralized bodies results in highly variable shapes and orientations of its zones. For this reason, no estimation of true widths can be provided for results at this stage. Drilling at both the tin-indium-zinc-copper and tungsten-molybdenum zones at the Mount Pleasant Mine Property is continuing, with both drills in operation on the property.

The 2008 drilling program is being completed as part of an ongoing review of the Mount Pleasant Mine Property with the purpose of completing an updated NI 43-101-compliant evaluation of the mineral resources.

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.
