GRS Gammon Gold Inc. Ordinary Shares

TORONTO, May 5 /PRNewswire/ - Gammon Gold Inc. ("Gammon") (TSX: GAM and NYSE: GRS): Gammon is pleased to provide an update of drill results from the Ocampo exploration program for the first four months of 2011.  As of April 30, 2011, the Company has completed a total of 56,704 metres of drilling at Ocampo, utilizing twelve drill rigs working on surface and underground.

Ocampo Underground Drilling Highlights

During the first four months of the year the Company has completed 145 core holes for 28,439 metres from underground. The primary focus of the underground drilling is to extend and delineate known resources along 6 vein structures in the Northeast Underground mine, the Level 2 mine and the Santa Eduviges mine.  Highlights of the program are as follows:

Aventurero

• Drilling highlights include:
• • Hole OU-826, 1.0 metre grading 105.65 grams per tonne gold equivalent⁽¹⁾
  • Hole OU-859, 7.4 metres grading 11.78 grams per tonne gold equivalent⁽¹⁾
  • Hole OU-884, 3.3 metres grading 48.11 grams per tonne gold equivalent⁽¹⁾
  • Hole OU-887, 0.8 metres grading 17.84 grams per tonne gold equivalent⁽¹⁾

San Amado

• Drilling highlights include:
• • Hole OU-948, 2.0 metres grading 25.20 grams per tonne gold equivalent⁽¹⁾
  • Hole OU-1063, 1.3 metres grading 54.88 grams per tonne gold equivalent⁽¹⁾
  • Hole OU-1064, 0.5 metres grading 35.43 grams per tonne gold equivalent⁽¹⁾
  • Hole OU-1067, 0.7 metres grading 64.42 grams per tonne gold equivalent⁽¹⁾

  • Hole OU-1023, 0.4 metres grading 42.53 grams per tonne gold equivalent⁽¹⁾
  • Hole OU-1026, 3.5 metres grading 16.61 grams per tonne gold equivalent⁽¹⁾

El Rayo

• Drilling highlight includes:
• • Hole OU-1140, 0.6 metres grading 37.16 grams per tonne gold equivalent⁽¹⁾

"The underground reserve drilling program has progressed very well in the first four months of 2011 with six active underground drill rigs." said Chris Bostwick, Senior Vice President, Technical Services. He continued, "We are particularly pleased with the bonanza style grades encountered at Aventurero and San Amado and note these two veins are already the largest in terms of ounces and strike length within the Northeast system of veins. Drilling at Santa Eduviges continues to produce results in line with reserve grades and ore vein thicknesses and we have just begun an underground follow-up program at El Rayo based on the successes of the surface drilling program there."

Ocampo Surface Drilling Highlights

During the first four months of the year the Company has completed 196 core holes for 28,265 metres on surface.  This work has been focused on five close-in targets where reserves were defined in late 2010 but remain open to expansion.  The work has proven very positive in that both high grades suitable for underground mining as well mineralization in configurations possible for open pit extraction, have been discovered.  Highlights of the program are as follow:

Altagracia

• Drilling highlights include:
• • Hole OG-1269, 5.1 metres grading 14.45 grams per tonne gold equivalent⁽¹⁾
  • Hole OG-1243, 0.5 metre grading 6.10 grams per tonne gold equivalent⁽¹⁾

Aventurero

• Drilling highlights include:
• • Hole OG-1273, 2.4 metres grading 7.46 grams per tonne gold equivalent⁽¹⁾
  • Hole OG-1290, 0.9 metres grading 15.34 grams per tonne gold equivalent⁽¹⁾

Belen Upper

• Drilling highlights include:
• • Hole OG-1285, 24.0 metres grading 2.76 grams per tonne gold equivalent⁽¹⁾
  • Hole OG-1291, 10.7 metres grading 2.66 grams per tonne gold equivalent⁽¹⁾
  • Hole OG-1272A, 32.6 metres grading 1.56 grams per tonne gold equivalent⁽¹⁾
  • Hole OG-1307, 6.7 metres grading 9.10 grams per tonne gold equivalent⁽¹⁾

El Rayo

• Drilling highlights include:
• •      Hole OG-1323, 0.5 metres grading 98.71 grams per tonne gold equivalent⁽¹⁾
  •      Hole OG-1331, 1.8 metres grading 42.74 grams per tonne gold equivalent⁽¹⁾

Jesus Maria

• Drilling highlights include:
• • Hole OG-1282, 3.1 metres grading 10.99 grams per tonne gold equivalent⁽¹⁾
  • Hole OG-1305, 1.7 metres grading 7.90 grams per tonne gold equivalent⁽¹⁾

"The surface exploration program continues to deliver excellent results at Ocampo. The results from the Altagracia vein have successfully delineated both high-grade ores as well as thick zones of mineralization that will be considered for potential open pit exploitation once the drilling is completed." stated Peter Drobeck, Senior Vice President of Exploration and Business Development.  He continued, "Results from the Belen Upper vein have also discovered some very high grades as well as thick zones of mineralization, and results from El Rayo have shown some of the highest grades on the property for the year.  The Company intends to continue drilling these and several new exploration targets during the second quarter of 2011."

Note:  1) All gold equivalent grades are calculated at the Company's long term ratio of 55:1.

This press release sets out the gold and silver grades found in the samples taken from various targets.  Not all of these targets have been categorized as a mineral resource deposit under applicable Canadian mineral resource reporting standards, and it is uncertain if further exploration will result in these targets being delineated as mineral resources.  The grades encountered so far should not be taken as representative of the ore bodies in question as there has been insufficient exploration to define a mineral resource, and such grades may not prove representative of the deposits if and when the same are delineated as mineral resources.
