Gammon to Record a Non-Cash Goodwill and Asset Impairment Charge Relating to El Cubo

TORONTO, August 6, 2010 - Gammon Gold Inc. ("Gammon") (TSX:GAM and NYSE:GRS): As previously
announced on June 17, 2008, the Company has indefinitely suspended operations
at the El Cubo mine, located in Guanajuato State, Mexico. This decision was a
result of continued labour disruptions by the unionized workforce and rising
operating costs associated with the failure of the unionized workforce to
achieve expected productivity levels.

This event was considered a triggering event for the purpose of assessing
whether the carrying value of the El Cubo mine's long-lived assets and
goodwill were impaired. As a result, the Company conducted a long-lived asset
impairment test whereby future life of mine cash flows reflecting recent
union productivity experience were determined and compared to El Cubo's
carrying value. Based on this test, the Company will record a goodwill and
asset impairment charge of US$193.3 million in the second quarter ending June
30, 2010. The remaining carrying value of the El Cubo mine's long-lived
assets will be US$60.9 million. While the charge will reduce second quarter
reported earnings by US$193.3 million, it is a non-cash accounting adjustment
and will not affect reported cash flows, cash balance, or proven & probable
reserves.

Further details will be provided in the Company's second quarter
financial statements and Management's Discussion and Analysis for the three
and sixth month period ended June 30, 2010. These financial statements will
be released before the market opens on Tuesday, August 10, 2010 and will be
available on the Company's website at www.gammongold.com or
www.sedar.com.
