METHANEX STARTS UP ONE MILLION TONNE GEISMAR 2 METHANOL PLANT IN LOUISIANA

VANCOUVER, BRITISH COLUMBIA–(Marketwired – Dec. 29, 2015) – Methanex Corporation (the “Company”) (TSX:MX)(NASDAQ:MEOH) announced that on December 27, 2015, the company successfully produced first methanol from its newly completed one million tonne Geismar 2 methanol plant in Geismar, Louisiana. The plant was relocated from the Company’s production site in Punta Arenas, Chile.

John Floren, President and CEO of Methanex commented, “We are extremely pleased to announce that our Geismar 2 plant is producing methanol roughly three months ahead of our original schedule. We expect the plant to ramp up to full production rates over the coming weeks. With the start-up of Geismar 2, we have successfully grown our operating capacity by approximately three million tonnes over the last three years. The total combined cost for the completion of the two Geismar plants is approximately $1.4 billion. We believe this represents a substantial cost savings relative to a new-build plant, and we expect the Geismar 2 plant will create significant cash-flow and value for shareholders.”

Mr. Floren added, “Our team has done an excellent job of managing the complex and multidimensional undertaking of relocating two plants from Chile to Louisiana. The project was completed ahead of schedule with excellent safety and environmental performance. A sincere thanks to all of the team members throughout the organization who have worked so hard to achieve this important milestone.”
