VANCOUVER, BRITISH COLUMBIA—(Marketwire – Nov. 13, 2012) – Methanex Corporation (TSX:MX)(NASDAQ:MEOH)(SANTIAGO:Methanex) announced today that it has been granted the required air permits by the State of Louisiana and the EPA to construct and operate its one million tonne methanol project in Geismar, Louisiana.

Bruce Aitken, President and CEO of Methanex commented, “This represents a key milestone for the project. With the air permits now in place, construction on the Geismar site can commence. Dismantling activities in Chile have been progressing well and the project remains on track to be producing methanol by the end of 2014. We believe this project will create significant value for shareholders, as it can be executed in significantly less time and with substantially less capital than a similar greenfield methanol plant.”

Methanex is a Vancouver-based, publicly traded company and is the world’s largest supplier of methanol to major international markets. Methanex shares are listed for trading on the Toronto Stock Exchange in Canada under the trading symbol “MX”; on the NASDAQ Global Market in the United States under the trading symbol “MEOH”; and on the Foreign Securities Market of the Santiago Stock Exchange in Chile under the trading symbol “Methanex”.
