Toronto -- October 21, 2009 – Adex Mining Inc. ("Adex" or the "Company") (TSX-V: ADE) is pleased to announce the launch of its updated and completely redesigned website. The Company’s management team and Board of Directors invite you to visit www.adexmining.com to see the new face of Adex and learn about recent accomplishments and current activities.

“The new Adex website was designed to present our corporate story in an easily understood and investor friendly format,” said Errol Farr, President and CEO of Adex. “Adex has achieved many important milestones over the past year and we believe that our website is a key part of our overall communications strategy, where we will continue to inform shareholders regarding the advancement of our multi-mineral Mount Pleasant Mine property.”

Adex is currently focused on its development plan for Mount Pleasant, with expectations of producing tin, indium and zinc from the North Zone (the “NZ”) at its wholly-owned Mount Pleasant Mine Property in southwestern New Brunswick, Canada (“Mount Pleasant” or the “Property”). Once the NZ resource is in production, Adex will expand its focus to include feasibility leading to production from the tungsten-molybdenum Fire Tower Zone (“FTZ”) at the Property.

A Preliminary Assessment Study on the NZ is on schedule for completion in autumn 2009. This is an important component of the Company’s development plan because it will provide a third-party economic assessment of a small to medium-scale mining operation including a forecast of mine production rates, capital costs to develop and sustain the operation, operating costs and cash flows. A positive result from this scoping study is expected to lead to a definitive feasibility study and subsequent production decision.

The NZ is the subject of a National Instrument 43-101 (“NI 43-101”) compliant Mineral Resource estimate including an Indicated Mineral Resource of 10,882,000 tonnes of at 0.43% tin, 67.8 grams per tonne of indium, and 0.67% zinc, and an inferred Mineral Resource of 7,603,000 tonnes at 0.22% tin, 74.6 grams per tonne of indium, and 0.99% zinc. An NI 43-101-compliant Technical Report including these resource estimates 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 is available on SEDAR at www.sedar.com.

Concurrent with the Preliminary Assessment Study, Adex is undertaking additional work as part of its NZ development plan. Activities currently underway include the design of a wastewater treatment system, the collection of bulk samples for bench and pilot plant work, and re-sampling of historical core from the 600 Adit for indium analysis.

Adex has sufficient financial resources to complete its NZ development work, including the definitive feasibility study.

Over the past year, Adex has also completed a number of important development activities at the tungsten-molybdenum FTZ, including the completion of a resource estimate and scoping study. The FTZ is the subject of a NI 43-101 compliant Mineral Resource estimate including an Indicated Mineral Resource of 13,489,000 tonnes at 0.33% tungsten and 0.21% molybdenum, and an Inferred Mineral Resource of 841,700 tonnes at 0.26% tungsten and 0.20% molybdenum. Based on the pricing assumptions in the scoping study, the FTZ is projected to generate approximately C$1.1 billion in revenue over a 13-year mine life according to a scoping study prepared by Aker Metals. An NI 43-101 technical report (the “FTZ technical Report”), including these resource estimates and an Executive Summary of the scoping study, 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 1, 2008 is available on SEDAR at www.sedar.com.

“The demand for tungsten, molybdenum, tin and indium has risen in recent years, fuelled by the development of new technologies and rapid growth in the developing world,” adds Mr. Farr. “Adex’s fundamental philosophy is to maximize shareholder value through appropriate and diligent extraction and processing of our mineral resources. Currently, Adex is developing the capacity to expand into value-added production of zinc, indium and tungsten products, thereby demanding higher value for our mineral resources while ensuring security in our market position.”

Trevor Boyd, P.Geo., the Company's Geological Consultant, a qualified person as defined by NI 43-101, supervised the preparation of the technical information contained in this press release in compliance with NI 43-101.

Mineral resources that are not mineral reserves do not have demonstrated economic viability.
