TORONTO, March 7 /PRNewswire/ - Gammon Gold Inc. ("Gammon") (TSX:GAM andNYSE:GRS): Gammon is pleased to announce that its ongoing drilling at the Guadalupe y Calvo Project in southern Chihuahua State, Mexico, continues to intercept high-grade gold-silver mineralization in the Northwest Extension of the Rosario Vein.

    Guadalupe y Calvo Drilling Highlights
    -------------------------------------------------------------------------
    Highlights from the 32-hole program include:

    -   Hole GC-185, 1.1 metres grading 62.37 grams per tonne gold plus 56
        grams per tonne silver, or 63.39 grams per tonne gold equivalent(1).
    -   Hole GC-203, 5.0 metres grading 8.96 grams per tonne gold plus 587
        grams per tonne silver, or 19.63 grams per tonne gold equivalent(1).
    -   Hole GC-207, 2.0 metres grading 8.64 grams per tonne gold plus 656
        grams per tonne silver, or 20.56 grams per tonne gold equivalent(1).
    -   Hole GC-215, 1.1 metres grading 19.21 grams per tonne gold plus 73
        grams per tonne silver, or 20.53 grams per tonne gold equivalent(1).

"We are very encouraged by the mineralization discovered in the Rosario Northwest Extension as it increases the length of the high grade mineralization a further 500 meters from the 2008 drilling program. The Northwest Extension has never been previously explored as the vein occurs below the post-mineral tuffs." stated Peter Drobeck, Senior Vice President of Exploration and Business Development. Mr. Drobeck continued, "Due to the success of the drilling program over the past 8 months, the Board of Directors have approved a budget of $4.0 to $5.0 million for 2011 to develop this new discovery. In addition, the Preliminary Economic Assessment is now being expanded to include these new and encouraging drill results."

Since resuming the drilling program at Guadalupe y Calvo in April 2010, the Company has drilled an additional 40 diamond drill holes (22,513 metres), of which 32 holes (19,721 metres) were drilled on the Northwest Extension of the Rosario system. The average of the 21 intercepts that reported over a 2.5 grams per tonne gold equivalent(1)cutoff is 1.9 metres grading 6.85 grams per tonne gold and 188 grams per tonne silver, or 10.36 grams per tonne gold equivalent(1). This step-out drilling is testing the extension of the major vein system at Guadalupe y Calvo underneath a thick series of post-mineral volcanic tuffs. The work has been very successful in discovering and delineating a wide zone of sheeted to locally stockworked vein system, ranging from more than 10 to over 100 meters in width, within which are narrower zones of high-grade mineralization that meet current underground cut-off grades at the Company's other underground operations. The expanded PEA is expected to be released during the second quarter of 2011.

Note: The Guadalupe y Calvo information has been reviewed by Qualified Person, Mr. Peter Drobeck. Sample analyses for Guadalupe y Calvo drilling were performed by both SGS Laboratories (based in Mississauga, Ontario using their facility in Durango, Mexico), and at ALS-Chemex Laboratories (based in Vancouver, British Columbia, using their facility in Hermosillo, Mexico). Gold was analyzed using standard fire assay procedures with AA finish, and silver by multi-acid digestion with AA finish. The Company has an established program of inserting certified control samples and blanks in compliance with best practices, and this program was used at Guadalupe y Calvo per Company policies. Sample lengths are not necessarily true widths.
