Normabec Finds Better Silver Grades Than Anticipated in Real de Catorce Tailings Piles

ST-BRUNO, QUEBEC--(CCNMatthews - Feb. 27, 2007) - Normabec Mining Resources Ltd. ("Normabec") (TSX VENTURE:NMB), through its wholly owned Mexican subsidiary Minera Real Bonanza S.A. de C.V., is pleased to announce excellent assay results averaging 93.72 g/t Ag (2.73 oz/t Ag) from its systematic sampling program over three tailings piles at the Real de Catorce silver project in San Luis Potosi State, North-Central Mexico.

This program consisted of systematic auger-type drilling (called "Penetrometro") on a 25- by 25- metre grid over three tailings piles. The drilling totaled 1,064.4 metres in 117 holes and more than 700 samples were collected at 1.5-metre intervals. The "Penetometro system" enables the collection of samples without the contamination that would take place with a standard auger or reverse circulation drilling equipment.

The former operator of the Real de Catorce silver project reported one pile graded 102.0 g/t Ag, while the other two graded 60.0 g/t Ag. In addition to confirming the validity of these estimates, the new work provided even better results than expected. Pile #1 gave an average grade of 109.8 g/t Ag, representing an increase of 7.6 percent over the anticipated grade. Pile #2 returned an average of 63.4 g/t Ag and pile #3 gave 68.6 g/t Ag, an increase of 5.7 percent and 14.3 percent, respectively, over the expected grades. The average grade of all three piles is 93.72 g/t Ag (2.73 oz/t Ag).

Now that all results have been received and compiled, the three tailings piles have been surveyed in detail and density calculations have been completed (average of 1.48), Normabec will give the mandate to Micon International of Toronto to carry out a 43-101 compliant mineral inventory for this material. Normabec is also preparing tailings material for metallurgical testing to be carried out at the University of San Luis Potosi and at a Canadian laboratory.

These results, coupled with those from the surface sampling of the Veta Madre structure, are very promising and will most likely enable the company to build a resource base that could be amenable to production in a relatively short period of time. Furthermore, an underground sampling program has been initiated in order to eventually transform the historical mineral inventory into a 43-101 compliant estimate. Norabec is now preparing for a 6,000-metre underground drilling program aimed at testing the eastern extension of the Veta Madre Structure.

Sampling was performed by Normabec technicians under the supervision of an experienced geologist. A majority of samples were 1.5 metres long while the last samples of each hole varied in length, based on core observation. All samples were prepared and assayed at the Laboratorio Metalurgico Courtade, S.A. de C.V. of San Luis Potosi.

Quality assurance and quality control (QAQC) was performed using two silver standards with one blank being introduced alternatively (every 25 samples). Duplicates are being performed by the laboratory. Pierre O'Dowd, P.Geo., is the Qualified Person (QP) for Normabec. He revised and approved this press release.
