MARATHON PGM ANNOUNCES NEW GEORDIE LAKE RESOURCE: INCREASED METALS, GRADE AND TONNES

TORONTO, May 4 /CNW/ - Marathon PGM Corporation (MAR-TSX) ("Marathon") today announced the completion of an updated NI 43-101 compliant resource estimate for the Geordie Lake PGM-Cu Deposit, located 14 km west of the town of Marathon, Ontario. The new resource estimate is substantially larger than the previous estimate of July, 2008. The Geordie Lake resource has the potential to extend the projected mine life of the Marathon PGM-Cu deposit well beyond the current forecast of 11.5 years. The combined measured and indicated ("M+I") resource for the Marathon and the Geordie Lake deposits now exceeds approximately 146 million tonnes and contains 4.87 million ounces of PGM and gold, 8.88 million ounces of silver and 881.70 million pounds of copper. Please click https://www.marathonpgm.com/index21.html to view the Marathon district resources.

Highlights:

- M+I contained metals - Pd up 40.3%, Pt up 39.1%, Au up 8.5%, Cu up 34.7%, Ag up 57.8%

- M+I resource tonnage increased by 24.7% (up 6.43 million tonnes)

- bulk of resource situated within a 600 m strike length

- mineralization identified in drilling over a 1.5 km strike length

- rock sampling has identified anomalous Cu and PGM values on strike, 2 km to the north

Phillip Walford, President and CEO of Marathon commented, "Marathon's first drilling program on the Geordie Lake Deposit was highly successful in delineating the upper part of the higher grade central core. The potential to further expand the resource is very high. The Geordie Lake Deposit has the potential to extend the life of the nearby Marathon PGM-Cu project, which has a designed milling rate of 8.0 million tonnes per year and an estimated mine life of 11.5 years."

(1) Mineral resources which are not mineral reserves do not have
demonstrated economic viability. The estimate of mineral resources
may be materially affected by environmental, permitting, legal,
title, taxation, sociopolitical, marketing, or other relevant issues.
(2) The quantity and grade of reported inferred resources in this
estimation are conceptual in nature and there has been insufficient
exploration to define these inferred resources as an indicated or
measured mineral resource and it is uncertain if further exploration
will result in upgrading them to an indicated or measured mineral
resource category.

The 2010 updated resource estimate for the Geordie Lake Deposit is based on 21 holes from Marathon's January 2010 campaign, 8 holes from a 1987 drill program by St. Joe Minerals, 9 holes from a 1999-2000 LEH Ventures ("LEH") drill program, 14 holes from a 2001 LEH drill program, 2 diamond drill holes from the 2002 LEH drill program and 3 diamond drill holes from the 2006 Discovery PGM drill program. Two holes drilled in 1997 were drilled parallel to the dip of the mineralized structure and were not used. The updated resource estimate was completed by independent geological consultant and Qualified Person, Martin Drennan, P.Eng of Python Mining Consultants of Hamilton, Ontario ("Python") and is expected to be filed on SEDAR (www.sedar.com) within 45 days.

Geordie Lake Deposit

The Geordie Lake deposit model consists of five mineralized "layers" which have been simplified to a hanging wall and main zone. Three dimensional ore bodies were created from a 25 metre section frequency along strike. Grade distributions for all metals were statistically analyzed and only a single silver assay was capped to the 95th percentile value. Composites 3 metres in length were formed from drill hole data passed through the mineralized layers. The block model was created using blocks of 2 m E-W, 2m N-S, 2 m vertical and populated by inverse distance squared interpolation. These results were compared with ordinary kriging and nearest neighbor (three interpolation methods were used in the analysis for grade distribution: Ordinary Kriging, Inverse Distance Squared, Nearest Neighbour with inverse distance being adopted as the best representation for this data set). Tonnes and grade have been limited to within the ore shells by means of the partial percentage application.Metal prices used in Python's estimate were Cu USD 2.91/lb, Au USD 819/oz, Pt USD 1347/oz and Pd USD 321/oz, and Ag USD 14.1/oz. The US/CDN exchange rate was
.87. The metal prices and exchange rate utilized were based on a 5-year average and exchange rate from February 2010. Average recoveries were taken from the bulk sample metallurgy test completed by Process Research - Cu 90.8%, Pd 80.1%, Pt 71%, Au 79.9%, and Ag 74.5%.The mineral resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council December 11, 2005.
