Rocmec Releases NI 43-101 Resource Estimate for its Rocmec 1 (Russian Kid) Property, Confirms Significant Upside Potential

POINTE-CLAIRE, QUEBEC--(CCNMatthews - March 20, 2007) - Rocmec Mining inc. (the "Company")(TSX VENTURE:RMI) is pleased to release the National Instrument (NI) 43-101 compliant resource estimate for the Company's Rocmec 1 (Russian Kid) Property, located 35 km from two World-Class Mining Camps, the Rouyn-Noranda Copper Gold Camp to the SE in Quebec, and the Kirkland Lake / Larder Lake Gold Camp to the SW in Ontario.

Systeme Geostat International of Blainville (Quebec) has authorized Rocmec to release results of its mineral resources. The undiluted and in-situ resource estimate within the ore zones is summarized as follows:


Cut-off Tonnes Grade Ounces Tonnes Grade Ounces Tonnes Grade Ounces
Grade (g/t (g/t (g/t
(g/t) gold) gold) gold)
3.0 91 600 6.72 19 800 274 200 6.37 56 100 955 200 10.37 318 450
0.1 107 800 6.06 21 000 414 000 4.92 65 550 2 250 000 6.32 456 900

(i) Calculations are in metric units with results were rounded to reflect their true estimated nature. Mineral Resources are not Mineral Reserves, since Mineral Reserves have a demonstrable economic viability. Systeme Geostat International Inc. has verified and is not aware of any environmental, permitting, legal, claim title, taxation, socio-political, marketing or other constraints that could affect the resource estimate.

Mr. Jean Lafleur, Director and Technical Advisor at Rocmec states " After just over one year of exploration and development work, the Company is extremely proud to now have National instrument 43-101 Mineral Resources at our Rocmec 1 property. The resources now stand at 86,550 ounces in the Measured and Indicated category and an additional 456,900 ounces in the Inferred category ". Mr. Lafleur adds " There is also a significant opportunity to expand the resources based on the kilometric-long gold corridor on the property ".

Mineral Resources Parameters

The Qualified Person responsible for the resource estimate is Mr. Claude Duplessis, P. Eng., of Systeme Geostat International Inc. The gold mineral resources were estimated on regular blocks on longitudinal sections by the inverse of distance method. The gold zones are Front West, McDowell, Talus, Shaft, Boucher and Boucher 2. The average true widths of the gold zones vary from 0.61 meters to 2.32 meters. High grade capping was done on the raw data and established at 45 g/t gold. Gold values were assigned to computer generated blocks (5 meters in Easting by 5 meters in Elevation by variable thickness in meters in Northing) using a maximum of 8 composite samples calculated from gold assay data sets of all drill holes individually in each of the mineralized zones. A grade times thickness approach was used for the accurate estimation of gold grades per blocks. Intersections were calculated on cross-sections and were projected on a East-West vertical projection. The longitudinal perimeters were constrained by the surface topography and the presence of intercepts laterally and at depth. The resource estimate was calculated using a specific gravity of 2.70 g/cm3. The known mineralization now lies from surface to a vertical depth of 400 meters and was delineated over a strike length of approximately 1.66 kilometers and individual widths of up to 4.10 meters. The complete National Instrument 43-101 Technical Report from Systemes Geostat International Inc. will be posted shortly on SEDAR (at under Rocmec Mining Corporation Inc.

The gold mineralization at the Rocmec 1 (Russian Kid) Property is linked to east-northeast, centimetric and metric wide quartz veins, dipping moderately to steeply to the south, within a kilometric long by 600 meter wide gabbro to granodiorite intrusive host. There are at least six major vein systems identified on the property; however recent underground work by the Company has confirmed that several veins are likely part of the same system, simply offset by north trending faults. The veins are part of diverging / converging or anastomosing fracture system than includes shearing, alteration (silica, chlorite, sericite, epidote and carbonate) and 2 to 10% disseminated and vein-type pyrite that can attain overall widths in excess of 30 meters.

The best known vein system is termed the McDowell Zone that may include three different vein sets, and has been recognized over a 1,660 meter long strike length, to a 317 meter depth, carrying an average of 6.07 g/t gold capped at 45 g/t over a 0.82 meter horizontal width.

The Company is planning an extensive drill program later in 2007 to test the down-dip extensions of all the mineralization zones to the -400 m vertical depth, and to outline higher quality gold resources more in-line with other gold systems in the Gold Mining Camps of the region.



About Rocmec Mining Inc.

Rocmec Mining Inc. is a Canadian junior exploration company actively involved in the acquisition, exploration and development of precious metal projects. The Company's exclusive thermal fragmentation process combined with its growth strategy place it as the partner of choice for the development of narrow high-grade precious metal quartz vein properties. The Company is listed on the TSX-Venture exchange and trades under the symbol: RMI

The company's growth strategy is to focus on the development of quality assets that will significantly enhance shareholder value. The exploitation of narrow high-grade vein deposits with its exclusive thermal fragmentation process should enable the Company to demonstrate the economic plus-value of this technology. The acquisition, development and future exploitation activities at the recently acquired Rocmec I (Russian Kid) property subscribe to this objective.
