ADE Adex Mining Inc

Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE:ADE) is pleased to
provide an update of activities on the tin-indium-zinc North Zone ("NZ") at its
Mount Pleasant Mine Property in southwestern New Brunswick, Canada.


In addition to continuing to work on flowsheet optimization for concentrate
production, Adex is also pursuing test programs focused on producing added-value
products from the NZ.


Concentrate Test Work

In 2010, the Company undertook a comprehensive bench scale and pilot plant test
program to produce zinc/indium concentrate and tin concentrate. Some 50 bench
scale and locked cycle tests and more than 110 hours of piloting consumed over
60 tonnes of NZ resource material. Data collected from the program were used to
a) develop a flowsheet for the production of zinc/indium and tin concentrates,
and b) meet technical requirements for sizing equipment to be used in the
projected Definitive Feasibility Study ("DFS"). Pilot plant concentrate products
are presently being assessed for upgrading to metals through hydrometallurgical
and pyrometallurgical testing facilities.


A second round of locked cycle testing is underway at SGS Lakefield to confirm
flowsheet parameters and to optimize concentrate grades and metal recoveries.


Hydrometallurgical Test Work

In 2010, the Company commenced a comprehensive hydrometallurgical test program
for the production of indium sponge metal and zinc metal. Adex has now developed
a proprietary hydromet technology based on chloride leaching and impurity
removal followed by extraction, stripping and recovery of zinc metal via
electro-winning and indium sponge via cementation.


Indium sponge metal grading 96.25% indium and zinc metal grading 98.89% zinc
were produced from the first full pilot plant run in December 2010/January 2011.
Results from the second full pilot run are expected by the end of March.


Adex intends to run the pilot plant through several hundred full cycles in order
to verify equipment materials integrity and to further optimize the process for
commercial production.


Pyrometallurgical Test Work

Adex has agreed to proceed with initial pyrometallurgical flowsheet development
at Xstrata Process Support ("Xstrata") in Sudbury, Ontario for the production of
crude tin metal from tin concentrate. Adex will deliver about 20 kilograms of
low grade tin concentrate to Xstrata and flowsheet development will commence
this month. Adex anticipates tin metal assaying higher than 95% tin from the
initial crude metal flowsheet.


Drill Results and Resource Estimate

The Company recently released the results of its 2010 drill program designed to
bring all of its North Zone resources into indicated status and further identify
mineable blocks intended for the DFS. Preparation of an updated National
Instrument 43-101 ("NI 43-101") compliant resource estimate for the North Zone
is now underway and is expected to be complete in about eight weeks.


Definitive Feasibility Study

Adex intends to complete a DFS leading to a production decision by the end of
2011. Data from the concentrate flowsheet development work will be combined with
hydrometallurgical and pyrometallurgical results to form base case analyses for
the DFS. Management is hopeful of awarding the contract for the DFS within the
next few months.


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 NI 43-101. Mr. Boyd supervised the preparation of
the technical information contained in this press release in compliance with NI
43-101.
