Adex Announces Receipt of Updated Approval to Operate

Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE:ADE) is pleased to
announce that it has received from the New Brunswick Department of Environment &
Local Government (the "Department"), an updated approval to operate the dormant
Mount Pleasant Mine site in care and maintenance. Approved operations include
treating wastewater from the flooded underground mine shafts, exploration
activities, operating metallurgical bench or pilot scale mill tests, and other
care and maintenance activities. The approval does not authorize Adex to dewater

The terms of the approval require Adex to continue to perform maintenance and
monitoring of the site, emergency reporting and response measures, monitoring
for detection of unapproved contaminant releases, surface water monitoring,
environmental effects monitoring and monthly reporting on the forgoing. 


Additionally, Adex is required, by March 31, 2013, to submit to the Department a
mine water management plan including a cost report on the plan, a tailings flood
plan and contingency plan, and an updated sludge cell project proposal and
timeline to complete. The approval also sets out parameters for the operation of
the new mine water treatment facility to be approved and constructed, and
parameters for the operation of the tailings impoundment facility which already
exists. Adex will also be required to post a rehabilitation bond, which may or
may not exceed the bond currently posted by Adex for this purpose.
