Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE: ADE) is pleased to announce it has successfully developed a process for the production of a high purity indium at its Mount Pleasant Mine Property ("Mount Pleasant" or the "Property"), located in southwestern New Brunswick Canada.

Adex overcame a major hurdle at the close of 2009 by producing the first few grams of indium in its bench scale hydrometallurgical process (the "hydromet process") development program. "I am very optimistic," stated Errol Farr, Adex President and CEO. "It doesn't seem like much when you hold it in your hand, but this little nugget sized piece of indium represents the promise of Adex's success at Mount Pleasant. The potential to produce and direct market a high grade indium product would put Adex in a unique position amongst junior mining companies."

The bench scale process development work completed to date indicates that the unique hydromet process technology is capable of producing indium in excess of 88% purity. Bench scale optimization of process chemistry to confirm design parameters for the hydromet pilot plant testwork is ongoing.

The hydromet process, developed by Thibault & Associates Inc. of Fredericton, an Adex consultant, involves leaching base metal sulphide concentrate containing approximately 4500 ppm indium and recovering the indium and zinc through a series of solvent extraction and solution purification processes. Adex is considering patent applications with respect to certain aspects of this hydromet process technology.

Indium production potential at Mount Pleasant is about 40 tonnes per year ("tpy") based on processing 850 tpd of mill feed. Adex is considering two commercial production scenarios for Mount Pleasant. Under the tin concentrate, indium and zinc metal production model, there is also potential to produce about 4,000 tonnes of zinc metal and 3,200 tonnes of tin concentrate per year from the North Zone ("NZ"). Under the tin concentrate and zinc-indium concentrate production model, there is potential to produce about 8,500 tonnes of indium rich zinc concentrate and 3200 tonnes of tin concentrate from the NZ.

With successful scoping/preliminary economic studies behind it as disclosed in the Company's press release dated January 7, 2010, the Company is now focused on piloting indium-zinc concentrate and tin concentrate production and on piloting its innovative hydromet process to produce indium and zinc metal. Successful pilot test programs will lead to a definitive feasibility study. Positive results from the definitive feasibility study will lead to applications for necessary regulatory approvals and efforts to secure financing to fund engineering, equipment purchase and construction, resulting finally in production.

Adex believes it will be well positioned to begin mine development and process equipment purchase and installation assuming positive results from its definitive feasibility study, government regulatory approvals and project financing by early 2011. Concentrator production is targeted for October/November 2011.

In addition to the tin-indium-zinc-copper bearing NZ, Mount Pleasant hosts the tungsten-molybdenum bearing Fire Tower Zone ("FTZ"). The FTZ is the site of a tungsten-molybdenum underground mining operation that was only in production between 1983 and 1985.

Mineral resources that are not mineral reserves do not have demonstrated economic viability.
