Marathon acquires Bird River Ni-Cu+PGM Property through option

April 18, 2007 - Toronto, Ontario: Marathon PGM Corporation (TSX: MAR) ("Marathon" or the "Company") is pleased to announce that it has signed an agreement with Gossan Resources Limited ("Gossan") to option the Bird River Project (the "Property").  The Property consists of 7,301 hectares and covers a strike length of over 21 km of the Bird River Sill Complex. The Bird River Complex carries significant mineralization of palladium and platinum along with nickel, copper, zinc and chromium.  The Property is located about 150 km northeast of Winnipeg, Manitoba on the Bird River Sill and approximately 6 km northwest of Mustang Minerals' Maskwa Deposit and the historic Dumbarton mine.

Phillip Walford, President and CEO of Marathon, added, "The acquisition of the large Bird River portfolio reflects Marathon's growth strategy of adding highly prospective projects near infrastructure and that have the geological potential to rapidly de velop PGM resources. Acquiring this project is an important step in the growth of the Company and will complement the work being done on our advanced Marathon PGM - Cu Project."

Platinum and palladium mineralization have recently been identified in several environments on the property, including nickel and copper mineralization in ultramafic rocks, reef style mineralization near and in the chromite layers and mineralization in the surrounding volcanic rocks.  Much of the earlier sampling and drilling on the Property did not test for PGM. 

Seven regional airborne electromagnetic targets have been identified and have yet to be drilled.  In addition, a zone of PGM-nickel and copper mineralization has been outlined on the eastern end of the Property on the Page Block by widely spaced drilling over a strike length of approximately 300 m.  The Page Zone appears to be geologically similar to Mustang Minerals' Maskwa deposit.  Intersections in the zone include drill hole BR-05-02 intersecting 13.5 m grading 0.73 g/t palladium, 0.27 g/t platinum, 1.08% nickel and 0.50% copper.  Included in that intersection was 4.75 m grading 1.11 g/t palladium, 0.40 g/t platinum, 2.14 % nickel and 0.44% copper.  Two widely spaced drill holes which intersected low grade PGM-nickel and copper mineralization establish the Page Zone as having a strike length of 1 km.   The Page Zone is an immediate drill target.

Dave Good, VP Exploration, stated "our team is excited about applying the exploration strategies and techniques learned at the Marathon property to other properties with the same potential. Developing a resource on the Page property will be a great way to start the project, and then by combining low- and high-tech methods such as prospecting and strategic geochemical and geophysical surveys we can efficiently and systematically evaluate the targets."

The planned summer program will field test and prioritize the most favourable anomalies by prospecting and conducting surface geochemistry.  In addition, numerous showings on the Property will be prospected.  Marathon is planning a Diamond drill campaign based on this work.  The Company has allocated geological staff for this work and, has sufficient resources to manage both the Bird River and Marathon projects.

Under the terms of the Agreement, Marathon can earn an undivided 50% interest in the Bird River Property by spending $3.0 million on exploration and making cash payments of $500,000 to Gossan by April 30, 2011.  Thereafter, Marathon can earn a further 15% interest by completing a definitive feasibility study and an additional 5% interest, to a total 70% interest, by arranging project financing.  Under certain conditions, Marathon may elect to issue its common shares in lieu of cash payments. Upon formation of a joint venture, Marathon must also make annual advance royalty paym ents of $100,000 until commercial production is achieved. The advanced royalty payments are recoverable by Marathon once in production. In the 1st year of this agreement, Marathon's work exploration commitment is $500,000 by April 30, 2008, with an initial cash payment of $50,000.    The Agreement is subject to TSX approval.

All exploration work is being performed under the guidance and supervision of Phillip C. Walford, President and Chief Executive Officer of the Company, a professional geologist and Qualified Person as defined by National Instrument 43-101. Mr. Walford has approved the contents of this press release.

About the Marathon PGM - Cu Project

The Company has a 100% interest in the Marathon PGM - Cu Project, located about 10km north of Marathon, Ontario. The Project is currently undergoing a definitive feasibility study and a 35,000 m drill campaign. As announced previously, the Company has completed a revised Preliminary Economic Assessment in compliance with the provisions of National Instrument 43-101, showing a potentially mineable measured resource of 39.2 million tonnes containing 1.6 million oz of PGM and gold and 285 million lbs of copper, and an indicated resource of 28.9 million tonnes containing 1.1 million oz of PGM and gold and 178 million lbs of copper.  An additional low-grade resource was also identified in the report completed by P&E Mining Consultants Inc. and filed on Sedar on April 5, 2007.
