Adex Update on Corporate Activities, Definitive Feasibility Study and New Drilling Underway

Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE:ADE) is pleased to
provide an update on corporate activities including the appointment of Patrick
Merrin as Chief Operating Officer. Adex also reports that the definitive
feasibility study ("DFS") for its wholly owned Mount Pleasant Mine property and
additional drilling are now underway. 


PATRICK MERRIN APPOINTED AS CHIEF OPERATING OFFICER

Adex has appointed Patrick Merrin as Chief Operating Officer ("COO"). Among his
initial responsibilities, Mr. Merrin will oversee completion of the DFS for
Mount Pleasant, which has now commenced. 


Mr. Merrin holds a bachelor's degree in chemical engineering from McGill
University and a Master's of Business Administration from the University of
Toronto's Rotman School of Business. He is a metals and mining executive with
more than 15 years of operations, business and engineering experience in
multiple countries. His background includes management and executive-level
positions with Xstrata Nickel and metals manufacturer Lucas Milhaupt (Handy &
Harman), working in both Canada and Europe. Mr. Merrin's leadership positions
built on his earlier experience as both a zinc and copper smelter process
engineer, and senior plant metallurgist. Mr. Merrin has also held progressively
senior mine foreman roles with Hudbay Minerals Inc. operations in Flin Flon,
Canada. 


"Patrick brings a tremendous amount of operating experience in a variety of
metals and mining environments to Adex and we are pleased to welcome an
executive of his calibre to the Company," said Linda Lam Kwan, interim President
and Chief Executive Officer for Adex.


FEASIBILITY STUDY COMMENCES AT MOUNT PLEASANT

Adex has commenced a flowsheet definition study and a mine dewatering plan as
part of a DFS on the company's Mount Pleasant Mine property. Thibault &
Associates Inc. of Fredericton, New Brunswick has been engaged to conduct the
studies.


The Mount Pleasant property includes two potentially economic mineral deposits -
the tin-indium-zinc North Zone and the tungsten-molybdenum Fire Tower Zone - and
is located in south-western New Brunswick, Canada. Both resource estimates are
compliant with Canada's National Instrument 43-101 (NI 43-101), Standards of
Disclosure for Mineral Projects.


The Mount Pleasant DFS will help Adex prepare for a potential production
decision by the end of 2012 and full production in 2014. 


ADDITIONAL DRILLING UNDERWAY AT MOUNT PLEASANT

Adex commenced a new 7,000-metre diamond drilling program at Mount Pleasant in
August. More than half of this new drilling is focused on the North Zone deposit
to add additional resources to the previously outlined NI 43-101 resource
estimates and acquire core for metallurgical testing. Adex has accelerated this
program with the use of two drills and expects the program to be completed by
mid-November and an updated 43-101 by year end.


The total Sn-In-Zn NI 43-101 resource estimate 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
completed in May 2009. These resource estimates are expected to be revised
upwards, based upon the results of both the 2010 and 2011 drill programs, when
an updated NI 43-101 technical report on the North Zone is completed in late
2011 or early 2012.
