ADE Adex Mining Inc

Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE: ADE) is pleased to provide an update on its tin, indium and zinc bench scale test project being carried out by SGS Lakefield Research Limited ("SGS") of Lakefield, Ontario to evaluate the production of tin concentrate and zinc-indium concentrate from the North Zone ("NZ") at Adex's wholly-owned Mount Pleasant Mine Property ("Mount Pleasant" or the "Property"), located in southwestern New Brunswick, Canada.

The bench scale program is a two-pronged approach. The first step is designed to produce indium-bearing zinc concentrate for further upgrading to a 95% indium sponge utilizing an exclusive hydrometallurgical process being developed for Adex by Thibault & Associates in Fredericton, New Brunswick. The second step is designed to test the production of a tin concentrate for direct sale to a tin smelter. Management and directors of Adex were present at SGS to observe the final stage of the bench scale program - locked cycle testwork on both products - on May 28, 2010. Test results will be released as soon as they are available.

The bench scale program will now lead directly to a pilot plant program which will be carried out at SGS. A 100 tonne sample from the NZ has already been received at SGS in Lakefield and the pilot plant will be set up over the next two weeks with pilot plant operations scheduled to begin by mid-June.

Errol Farr, President and CEO of Adex, stated: "We are very pleased with both the metallurgical and hydrometallurgical progress of our NZ test work to date. We look forward to assessing the final results of the bench scale metallurgical program, and anxiously await pilot plant results which will be used for scale up to commercial production."

Adex's Mount Pleasant Property hosts two important and separate mineral resources: the tungsten-molybdenum bearing Fire Tower Zone (the "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.
