Rocmec Increases Measured and Indicated Resources at Its Rocmec 1 Gold Property

VAUDREUIL-DORION, QUEBEC--(Marketwire - May 20, 2010) - Rocmec Mining inc. (the « company ») (TSX VENTURE:RMI) (FRANKFURT:D5O) is pleased to announce results of revised NI43-101 resource calculation report prepared by SGS Geostat regarding its Rocmec 1 gold property located in Rouyn-Noranda, Quebec. This report will be available on SEDAR ( [ www.sedar.com ] ) in the coming days.

The drilling results from 2010 have delineated measured and indicated resources of the Boucher and Boucher 2 structures totalling 22,700 ounces respectively the Boucher Structure of 58 700 tonnes at 5.46 g/tAu totalling 10,300 ounces and the Boucher 2 structure of 31,500 tonnes at 12.20g/t Au totalling 12,400 ounces with a cut-off grade of 3 g/t This is the first time that Rocmec obtains this type of resource category for the structure that was discovered in 2006. The Boucher vein has now been indentified over a distance of 450 meters in length, at depths of 450 meters and remains open in all directions.

In summary, by viewing the classification table of global resources below, prepared with a cut-off grade of 3 g/t, an industry standard. The resources measured/indicated now total 570,300 tons at 6.52 g/t or 119,500 ounces vs. 477,400 tons to 5.59 g/t or 85,900 ounces as announced in the press release dated March 3^rd 2010.

Bloc extraction parameters

The T1, T2 and T3 blocks were estimated as individual blocks of definite volume. SGS used mineralized intervals of a minimum of 0.3m horizontal width for all of the structures. The 0.3m minimum width was selected according to the mining method used by Rocmec which is thermal fragmentation, extracting narrow structures and veins with a minimum of 0.3m (true width).

The grade of the composites were extrapolated to a radius of about 25m by 25m, taking into account its horizontal thickness. Estimating block was in contact only overburden or contacts as well as topographical boundaries of mining.

Polygonal parameters

The Front West and Talus 2 structures were estimated using a polygonal estimation method. SGS used mineralized intervals of a minimum of 0.3m horizontal width for all of the structures. The 0.3m minimum width was selected according to the mining method used by Rocmec which is thermal fragmentation, extracting narrow structures and veins with a minimum of 0.3m (true width).

The composites graces were extrapolated on a 35m radius.

The estimation was restricted to the overburden or topographic contact as well as the laim boundaries.

Bloc Model parameters

Block modeling was done on the Boucher, Boucher 2, McDowell, Shaft veins/structures. SGS used mineralized intervals of a minimum of 0.3m horizontal width for all of the structures.The 0.3m minimum horizontal width was selected according to the mining method used by Rocmec which is thermal fragmentation, extracting narrow structures and veins with a minimum of 0.3m (true width). The block model is estimated within Rocmec's claims and restricted to the overburden or topographic contact. The claims are considered in good standing. However SGS did not do an extensive status verification of Rocmec's claims. Coordinates used are in local mining grid. A maximum elevation level of 9990m was used since no topographic surface is available for the moment. A different set of 2D composites was used for the estimation of the Boucher and Boucher 2 structures from the rest of the Rocmec 1 structures. A specific gravity of 2.7 was used. Normal inversed distance was used for the estimation. The estimated resources were classified in accordance with the specifications of the 43-101 Policy, namely in measured, indicated, and inferred resources. Classification was done according to the density of drilling and level of confidence of the data.

Classification

The estimated resources were classified in accordance with the specifications of the 43-101 Policy, namely in measured, indicated, and inferred resources. Classification was done according to the density of drilling and level of confidence of the data.

Measured Category

An outline was drawn and used in the block modeling software in the vicinity of existing underground openings.

Indicated Category

An outline was drawn and used in the block modeling software in the neighbouring of existing openings and closed spacing intersects, according to the amount of available intersects.

Inferred Category

An outline was drawn and used in the block modeling software within the perimeter of the modeled zone and recognized by at least a pierce point.
