Normabec Confirms 4.1 Million Ounces of Silver Contained in Tailings at the Real de Catorce Project in Mexico

ST-BRUNO, QUEBEC, CANADA--(Marketwire - Aug. 27, 2007) - Normabec Mining Resources Ltd. ("Normabec")(TSX VENTURE:NMB)(FRANKFURT:N6M), through its wholly owned Mexican subsidiary Minera Real Bonanza S.A. de C.V. ("MRB"), is pleased to announce that Micon International of Toronto has handed an updated NI 43-101 technical report and a tailing resource estimate for the Real de Catorce property located in the San Luis Potosi State, northern central Mexico.

The following resource estimate was produced for three tailings piles of various grades and size.

Micon' report states that "Micon believes that the Normabec resource estimate as audited by Micon meets the current CIM definition for measured mineral resource". The report also mentions that "The database for the tailings resource estimate consists of 117 drill holes totaling 1,065.60 m. Sampling in each hole was limited to 1.5 m samples or less and 743 tailings samples were collected during the drill program. In addition to the regular sampling 47 control (QA/QC) samples and the results of the specific gravity testwork are included in the database."

Preliminary metallurgical testing carried out at the Instituto Metalurgico of the San Luis Potosi University indicates that 73% of the silver contained in Pile #1 could be recovered by straight cyanidation while an average of 65 % could be recovered for the three piles. The Institute believes that a further 15% could be recovered if regrinding is carried out before cyanidation. More testing is in progress. A pre-feasibility has been commissioned to evaluate the economics of extracting the silver from the tailings independently from the mine (press release April 23rd 2007). This report should be available in the coming weeks.

Normabec has started an 11,000 metre drilling program aimed at testing the continuity of the ore within the Veta Madre structure. One drill is active underground while the other operates from surface. Sampling of Veta Madre was completed at surface and on levels 845 and 800 (the two closest levels from surface). The company intends to produce a 43-101 technical resource estimate for that structure in the coming months.

This press release was reviewed and approved by Pierre O'Dowd, geologist and qualified person as well as by Bill Lewis, co-author Micon's technical report.

Normabec is a junior mining exploration company listed on the TSX Venture Exchange, under the symbol NMB, active in both Canada and Mexico in exploration of high quality assets.
