Adex Updates Development Strategy for Mount Pleasant Mine

Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE:ADE) is pleased to
announce an updated development plan with a primary focus on restarting
production at the Fire Tower Zone ("FTZ") tungsten-molybdenum-bismuth
("WO3-MoS2-Bi") project, located at its Mount Pleasant Mine property in
southwestern New Brunswick, Canada.


"The high grade drill results from our fall campaign have shown the potential
for a significantly longer mine life for our WO3-MoS2-Bi project. A longer mine
life combined with the strong tungsten markets indicate that the financials from
the Aker Solution scoping study could be significantly improved," said Patrick
Merrin, Chief Operating Officer at Adex. The FTZ scoping study showed a pre-tax
internal rate of return ("IRR") estimated at 27.1% and an estimated pre-tax net
present value ("NPV") of $164.6 million using a discount rate of 8% over a
13-year mine life.


Better-than-expected results from the 2011 drill program, released in our update
from January 31, 2012, identified new intercepts containing high-grade tungsten
(WO3), molybdenum (MoS2) and bismuth (Bi) at the North Zone ("NZ") and Saddle
Zone, which lies between the NZ and FTZ about 500m from each. These results
support the change to the Company's development strategy and extend known WO3,
MoS2 and Bi mineralized bodies.


"As our desire is to bring the Mount Pleasant Mine back into production as
quickly and efficiently as possible, it is clear that focusing on the Fire Tower
Zone is the best path forward," said Merrin. "The geology, mining and metallurgy
for the Fire Tower Zone are all well understood because it was previously mined
by Billiton Exploration Canada back in the mid-80s. This also makes the Fire
Tower Zone a lower risk project as we continue to better understand how to
maximize value from the North Zone." Merrin also explained, "The North Zone
testing that was completed earlier this year has given us good direction in how
to handle the metallurgy of that resource but further testing is required."


In keeping with its plan to begin mining the FTZ in early 2015, Adex has
commenced metallurgical feasibility testing which is required to re-start
production. This testing is expected to be completed in the third quarter of
2012.


The plan also includes the production of potential final marketable metal
products from the FTZ such as ammonia para-tungstate ("APT") and molybdenum
dioxide or molybdic oxide, which are in demand in the high-tech metals industry.


The management team and Board of Directors at Adex are confident in the changes
and fully support the new development plan, which they believe offers greater
potential benefits to the Company and its shareholders.


As part of its updated development strategy, Adex is planning for the FTZ to be
the first to reach production. Results from the updated National Instrument
43-101 ("NI-43-101") on the NZ remain scheduled for release in February 2012 as
indicated in our press release of January 31, 2012. 


The total NI 43-101 resource estimate for the FTZ presently includes an
Indicated resource of 13,489,000 tonnes at 0.33% WO3 and 0.21% MoS2, as well as
an Inferred resource of 841,700 tonnes at 0.26% WO3 and 0.20% MoS2. Details of
this resource estimate are described in the NI 43-101 Technical Report entitled:
"A Technical Review of the Mount Pleasant Property, Including an updated Mineral
Resource Estimate on the Fire Tower Zone Southwestern New Brunswick for Adex
Mining Inc." dated December 8, 2008, which was completed by Watts, Griffis and
McOuat Limited, Consulting Geologists and Engineers. 


The total NI 43-101 resource estimate for the NZ presently includes an Indicated
resource of 10,882,700 tonnes grading 0.43% Sn, 67.8 g/t In and 0.67% Zn plus an
Inferred resource of 7,602,800 tonnes grading 0.22% Sn, 74.6 g/t In and 0.99%
Zn. Details of this resource estimate are described in the NI 43-101 Technical
Report, entitled: "A Technical Review of the Mount Pleasant Property, Including
a Mineral Resource Estimate on the North Zone, Southwestern New Brunswick for
Adex Mining Inc.", dated May 6, 2009, which was completed by Watts, Griffis and
McOuat Limited, Consulting Geologists and Engineers, and SGS Geostat Limited.

Quality Assurance/Quality Control

Adex has implemented an industry standard QA/QC program. NQ Core is split in
half using a hydraulic core splitter, sampled in three meter intervals, sealed
in secure packages and transported directly by Adex personnel to the Activation
Laboratories preparation facility in Fredericton, New Brunswick. Pulps are sent
by bonded carrier from the facility to Activation Laboratories in Ancaster,
Ontario for analysis of tin and tungsten using Fusion XRF, and of indium,
molybdenum, bismuth, arsenic, zinc, copper and lead using sodium peroxide fusion
with either ICP-MS or ICP-OES finish. Some samples were analyzed for tungsten
and tin by ICP-OES method and comparative analyses showed no significant
differences with the Fusion XRF results. A pulp duplicate unknown to the
laboratory is submitted per batch of 10 samples, and sent to S.G.S. Laboratories
in Toronto for analysis of indium using sodium peroxide fusion with ICP-MS
finish and of tungsten, molybdenum, tin, bismuth, arsenic, zinc, copper and lead
by ICP-OES finish. A polymetallic standard unknown to the laboratory is included
with each batch of duplicate samples. Both S.G.S. and Activation Laboratories
comply with standard QA/QC protocols and are ISO 9002 accredited laboratories.


Qualified Person

The Mount Pleasant exploration program is being conducted under the direction of
Dr. Steve McCutcheon, P.Geo., the company's independent Geological Consultant
and a qualified person as defined by National Instrument 43-101. Dr. McCutcheon
approved the disclosure of the technical information contained in this press
release.
