Marathon extends mineralized zone to 800 m at the Coppermine Zone,
Bird River Property, SE Manitoba
Toronto, Ontario, August 29, 2007 - Marathon PGM Corporation (MAR -- TSX) ("Marathon" or the "Company") is pleased to provide an update of ongoing exploration at the Bird River Sill property ("Bird River"). Prospecting and data compilation of the Bird River property is proceeding over several key areas, including the Coppermine, Page East, Page West, and Galaxy Zones as well as 8 predefined airborne geophysical anomalies. Multiple successes have arisen from the prospecting and exploration program.
Marathon has identified an 800 m zone of mineralization in the Coppermine Zone - located in the western end of the Bird River property, and confirmed mineralization approximately 130 m east of the Page East zone - located in the northeast end of the Bird River property. The Coppermine and Page Zones are on-strike 20 km apart from each other and separated by highly prospective ground which is currently being explored. It is clear that mineralization is more extensive than first thought in both zones and they are now priority drill targets for planned drilling in the first quarter of 2008. Ground checking 3 of the 8 geophysical anomalies has discovered iron sulphide mineralization, with assays pending on the samples taken.

Finances
Marathon is well funded to complete the feasibility study on the 100% owned Marathon PGM-Cu property. The Company has no money invested in high-risk investments. All funds are in a series of 30-day bankers acceptance notes from the Toronto Dominion Bank.
Coppermine Zone
Prospecting and assays from grab samples has extended the strike length of mineralization north east of the Coppermine Zone to 800 m. Marathon initially reported this mineralization (MAR release 11-Jun-07) at the west end of the Coppermine Zone, with reported values of up to 0.21% nickel, 0.44% copper, 1.21 g/t platinum and 1.39 g/t palladium. A single hole located at the east end of the Coppermine Zone drilled by Canex Placer Ltd in 1973 (assessment file report 91832, Manitoba Mining District) contained an intersection grading 0.24% nickel, 0.42% copper, 1.02 g/t platinum and 1.19 g/t palladium over 12.2 m. Additional prospecting along strike from this hole yielded a total of 77 grab samples, of which 20 returned values of greater than 0.5 g/t platinum plus palladium, including 8 samples in the range of 1-3 g/t platinum plus palladium.
Page East Zone
Prospecting by Marathon has confirmed the extension of Page Zone mineralization at the footwall of the Bird River Sill by a distance of 130 m to the east. The best assays from grab samples include 0.90% copper, 0.09% nickel and 0.73 g/t platinum plus palladium in sample C377551 and 0.11% copper, 0.42% nickel and 0.58 g/t platinum plus palladium in sample C377552. The additional sampling has expanded the prospective strike length of Page Zone to over a kilometer.
Phillip Walford, President and CEO, stated "These results are very positive and have far exceeded our expectations. It will be very interesting to see how many of the mineral showings in the 20 km between the Page and Coppermine Zones develop into deposits."
Geophysical Anomalies
A total of eight airborne geophysical anomalies, identified by an EM/magnetic survey flown in 2005, have been investigated by prospecting. These geophysical anomalies span an east to west distance of 14 kilometres and are located immediately north of the Bird River Sill. Prospecting has discovered iron sulphides at 3 of the 8 geophysical anomalies, named "D", "E" and "F".
Following these recent prospecting successes, Marathon has staked additional claims around the original joint venture block held with Gossan Resources Limited.
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.

As announced previously, the company has completed a revised preliminary economic assessment in compliance with the provisions of National Instrument 43-101, showing a measured resource of 39.2 million tonnes containing 1.6 million ounces of PGM and gold and 285 million pounds of copper, and an indicated resource of 28.9 million tonnes containing 1.1 million ounces of PGM and gold and 178 million pounds 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.
In April 2007, Marathon entered into an option agreement with Gossan Resources on the Bird River Sill Ni-Cu and PGM property, located in Southeastern Manitoba. Marathon is conducting exploration activities through 2007 at the Bird River Sill and is planning a drilling campaign.
