Marathon Files Geordie Lake NI 43-101 Technical Report

TORONTO, June 18 /CNW/ - Marathon PGM Corporation (MAR-TSX) ("Marathon")

reports it has received the NI 43-101 F1 technical report of the 100% owned

Geordie Lake PGM-Cu Project ("Geordie Lake") located 14 km northwest of

Marathon, Ontario. The report is on SEDAR and the Company's web page at

www.marathonpgm.com

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 contained metals - 731,200 oz PGM+Au, 263.7 million lbs Cu and

3.06 million oz Ag

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

-PGM-Cu mineralization identified in drilling over a 1.5 km strike

length and remains open

-rock sampling has identified anomalous Cu and PGM values on strike,

2 km to the north

>>

"Exploration of the Geordie Lake deposit will continue on strike to the

north beyond the limits of the current resource. The on-strike surface

expression of mineralization has not been drill tested thus far, so this

summer's mapping will provide us with new geological information," said Dave

Good, VP of Exploration.

The Geordie Lake Deposit is being explored as a potential source of long

term mill feed for the proposed Marathon open pit mine which could potentially

extend the projected operational life. Marathon is starting to collect

baseline environmental data for the Geordie Lake Deposit.

2010 Resource Estimate

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 open pit mine life of the Marathon PGM-Cu facilities 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.

(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.

About Marathon PGM Corporation:

Marathon is actively developing resources in the immediate vicinity of

the Marathon Deposit to expand the life of the planned large tonnage, open pit

mining operation. The Marathon Deposit is one of the largest PGM-Cu reserves

in Canada and is expected to grow with the development of additional nearby

resources. Marathon's optimized P+P reserve of approximately 91.45 million

tonnes grading 0.832 g/t Pd, 0.237 g/t Pt, 0.085 g/t Au, 0.247% Cu and 1.44

g/t Ag, contains approximately 2.44 million ounces of Pd, 696,000 ounces of

Pt, 251,000 ounces of Au, 497 million lbs of Cu and 4.23 million ounces of Ag.

Marathon also has development and exploration stage properties in southeastern

Manitoba and western Newfoundland respectively. Marathon's Management plans to

build on its experience through the advancement of its properties and by

examining other strategic opportunities.
