VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 12/07/12 -- Methanex
Corporation (TSX:MX)(NASDAQ:MEOH)(SANTIAGO:Methanex) announced today
that it has filed an amendment to its short form base shelf
prospectus dated November 10, 2011 (the "Shelf Prospectus") with the

statement on Form F-10 in accordance with the Multijurisdictional
Disclosure System established between Canada and the United States.
The amendment increases the aggregate amount of debt securities
("Offered Debt Securities") that may be offered under the Shelf
Prospectus from US$500,000,000 to US$750,000,000. As of the date of
this amendment, Methanex has distributed Offered Debt Securities
under the Shelf Prospectus having an aggregate principal amount of

relating to a particular offering of securities, the net proceeds
from any sale of any securities will be used for any one or more of
capital expenditures, debt repayment, working capital or other
general corporate purposes.

these securities has not yet become effective. These securities may
