Normabec Traces 194.5 g/t Ag Over 535 Metres from Surface Sampling at the Real de Catorce Silver Mining District

ST-BRUNO, QUEBEC--(CCNMatthews - April 4, 2007) - Normabec Mining Resources Ltd. (TSX VENTURE:NMB), through its wholly owned Mexican subsidiary Minera Real Bonanza S.A. de C.V., is pleased to announce more excellent results from a surface sampling program at the Real de Catorce silver project in San Luis Potosi State, North-Central Mexico.

This latest program consisted of the second phase of surface sampling over the Veta Madre structure. A total of eight channel sample lines were performed and sampled over an additional 155 metres of strike length of that vein. The average grade of all eight channel samples is 204.1 g/t Ag.

The eight channel sample lines were spaced between 25 and 40 metres apart with their lengths varying from 3.0 to 14.2 metres. The table below shows the results from this second phase.

Line # Width (metres) Ag g/t

VM-8 9.5 138
VM-9 10.0 382
VM-10 14.2 239
VM-11 3.4 272
VM-12 12.5 117
VM-13 3.0 296
VM-14 5.5 50
VM-15 4.9 160

A total of two phases of sampling have now been carried out over a productive portion of the Veta Madre vein and it has been sampled over a strike length of 535 metres at surface (see news release dated February 20, 2007). The average grade of the two phases is 194.5 g/t Ag (5.68 oz/t Ag). These results are impressive and more sampling is being carried out over several other veins on the property to evaluate their open pit potential as well.

Sampling was performed by Normabec's geologists using continuous chip samples of various lengths (10 centimetres long by 2 centimetres deep). Samples were prepared and assayed at Chemex Lab of Guadalajara, Mexico. Methods used are Au-ICP21 for gold and ME-ICP41 for multi elements including silver. Detection limits for Ag are 0.2-100 parts per million (ppm; one ppm equals one g/t). Silver values higher than 100 ppm are submitted to method AG-AA46 consisting of aqua regia digestion with ICP-AES or AA finish (up to 1,500 ppm Ag). Quality assurance/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.

Normabec Mining Resources Ltd. is a mining exploration company currently exploring properties in Mexico and Canada. The company holds the mineral rights to several properties in Quebec, including the Pitt Gold property north of Rouyn-Noranda and the Real de Catorce property located in San Luis Potosi State, Mexico.
