Methes Energies Postpones Purchase of Property near Sarnia, Ontario

New York, May 12, 2008 – Methes Energies International Ltd. announced today that its wholly-owned subsidiary, Methes Energies Canada Inc., has agreed to postpone the closing of the 22-acre facility purchase near Sarnia, Ontario, Canada.   The original closing date was scheduled for April 30th, 2008; however, to allow the vendor to complete the site cleanup, the closing date has been postponed until May 29th, 2008.

The decision to delay the closing of this property purchase was agreed by both parties and does not modify, in any way, any of the conditions set forth in the purchase agreement. It should be noted that this delay will also impact the commencement date of operation accordingly, which is now scheduled to be in the 3rd quarter of 2008.

As previously mentioned in earlier Press Releases, Methes Energies intends to convert this site into a biodiesel facility that will produce 6.6 million gallons (25 million liters) of biodiesel per year.  As the site already carries most of the infrastructure and equipment needed for us to produce biodiesel, it will only take a few weeks to ready the site for the installation of our 5 Denami 600 biodiesel processors.  Included in the price of $ 2.2 Million Canadian dollars that Methes Energies has agreed to pay, is approximately 1.2 million gallons (4.6 million liters) of storage facility (tanks), 3,400 linear feet of rail in 4 spurs with train and truck loading racks, lab equipment, a water treatment plant, several furnished buildings, as well as an office space, air compressor, 2 X 1 million BTU boilers, and a complete fire suppression system.

The new facility will employ approximately 6 people.
