Normabec Confirms Historical Grades at Real de Catorce Silver Property

ST-BRUNO, QUEBEC--(CCNMatthews - May 2, 2007) - Normabec Mining Resources Ltd. ("Normabec") (TSX VENTURE:NMB), through its wholly owned Mexican subsidiary Minera Real Bonanza S.A. de C.V. ("MRB"), is pleased to announce that underground sampling of historical reserve blocks within the Santa Ana Mine is confirming silver grades reported by the former operator of the Real de Catorce silver project.

The objective of the underground sampling program is to transform the historical inventory into a 43-101 compliant resource estimate. The program consists of re-sampling approximately 10 percent of the reserve blocks that were defined by the former operator in 1990. To be representative, the sampling is being carried out within various veins and at various levels of the mine and has been designed to duplicate the historical sampling as much as possible. Initial channel sampling was performed at every two metres. However, upon the recommendation of mining consultants Micon International, the current sampling is being performed at every six metres along the veins where access is possible.

The underground historical inventory estimate at Real de Catorce is 533,000 tonnes grading 275 g/t Ag. Partial results obtained from the new sampling program demonstrate that historical grades are being reproduced in all the blocks sampled so far. These results support the accuracy of the historical estimate.

The following table summarizes the results obtained so far:



Vein Historical Avg Number New Sampling Avg
g/t Ag of samples g/t Ag

Anden 258 40 200
Anden 338 21 1,037
Amestoy 225 49 226
Rayas 1459 12 1,190
Veta Madre 283 100 310
Veta Madre (partial) 276 96 324


Given the very erratic nature of silver mineralization in the district, these results are considered quite representative of the historical sampling.

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.
