These three new deposits have been discovered through the first phase drilling program during the first half of 2010.

Two of the new discoveries are underground deposits; Santa Eduviges (Reserves of 44,961 gold equivalent ounces(1)), currently being developed as the second underground mine at Ocampo and Belen/Santa Juliana (Reserves of 50,529 gold equivalent ounces(1)), which are new veins discovered in the main NE underground mine. The third new discovery, Las Molinas, is a new open pit deposit (Reserves of 32,260 gold equivalent ounces(1)). These Reserves will be updated during the second half of 2010 and will be incorporated into the 2010 Reserves and Resources Statement along with additional Reserves and Resources delineated through the Company's ongoing drilling program at Ocampo in the second half of the year. The Company expects to issue the 2010 Reserves and Resources Statement by the end of first quarter of 2011.

"We are particularly pleased that these additional reserves were from new discoveries. These initial results highlight the potential of the Ocampo property as well as our surrounding land package," stated Rene Marion, President and CEO of Gammon. "For the remainder of 2010, we plan to complete an additional 45,000 metres of drilling at Ocampo targeting additional in-pit resources along the PGR Trend, as well as new open pit and underground targets."

    Notes to Mineral Resources and Reserves Tables:

    1. Gold equivalent calculations use reserve metal prices of $945/oz for
       gold and $15.20/oz for silver for a gold to silver ratio of 62.17:1
    2. Reserves additions have been calculated in accordance with NI 43-101,
       as required by Canadian securities regulatory authorities. Mineral
       Reserves additions have been calculated as at June 30, 2010.
    3. Grade represents an average, weighted by reference to tons of ore type
       where several recovery processes apply.
    4. The metallurgical recovery applicable for each deposit and the cut-off
       grades used to determine Reserves additions as at June 30, 2010 are as
       follows:

                                  Au              Ag
                       Metallurgical   Metallurgical                 Cut-off

    -------------------------------------------------------------------------

    All ores at Ocampo demonstrate similar metallurgical recoveries
    regardless of whether oxides are sulfides.

    5. The Los Molinas Open Pit strip ratio is 5.5:1.
    6. The basis for the reserve estimation is the Whittle pit optimization
       methodology.
    7. Sums may not add to totals due to rounding.
