Normabec Releases its Initial Resource Estimate on the Real De Catorce Silver Project in Mexico

MONTREAL, QUEBEC, CANADA--(Marketwire - June 19, 2008) - Normabec Mining Resources Ltd. (TSX VENTURE:NMB) (FRANKFURT:N6M) ("Normabec" or "the Company"), through its wholly owned Mexican subsidiary Minera Real Bonanza S.A. de C.V. ("MRB"), is pleased to release the results of its initial NI43-101 resource estimate on the Real de Catorce Silver project in north-central Mexico.

Resource Estimate
Measured Resources: 18,559,110
Indicated Resources: 10,202,088
Measured in tailings: 4,075,305 (August 2007 press release)
Measured and indicated: 32,836,503 ounces of silver

Conceptual Mineral Potential: 82.6 to 177 Moz

The NI 43-101 resource estimate prepared by Micon International of Toronto mainly refers to the first phase of diamond drilling conducted on the Veta Madre vein between the months of September 2007 and April 2008. This estimate includes areas sampled and drilled on the Veta Madre structure (41 surface and 27 underground drill holes, 32 surface channels) as well as the historical inventory as estimated by the former operator and re-estimated by Normabec after conducting a QA/QC sampling program.

The resource estimate of Veta Madre alone estimated using grade capping and total resources excluding tailings are shown on the following table:

This table indicates that the portion of the Veta Madre explored to date (approx 40 % of the known extent of the vein) hosts 24.3 M oz Ag, including 15.3 M oz in the measured category and 9.0 M oz in the indicated category. Average width of the vein is approximately 5 metres. The additional resource, which includes 13 veins in addition to Veta Madre, adds 4.5 M oz Ag to the Veta Madre resource estimate (Qualified Person: Bill Lewis of Micon). The average grade of the measured category is 221 g/t Ag while the indicated category stands at 321 g/t Ag for an aggregate grade of 248 g/t Ag. This grade does not include any polymetallic credits coming from the lead and zinc. When adding the resources already estimated for the tailing piles (August 2007, 4.1 M oz Ag), the property now hosts nearly 33 M oz Ag.

No historical record or recovery figures are available for the zinc and the lead, at this time however, metallurgical test work on the sulphide mineralization is in progress. This type of mineralization is typical of Mexican silver mines and no major recovery problems are expected at this time.

When removing grade capping on the Veta Madre Resource Estimate, it is increased by 10% (from 24.3 M oz to 26.8 M oz Ag). The average grade of the measured resource is then up graded from 213 g/t Ag to 221 g/t Ag while the indicated portion from 332 g/t Ag to 403 g/t Ag.

Numerous results are still pending from the Veta Madre drilling program and surface sampling of other veins and numerous intersections belonging to Refugio and various hangingwall and footwall veins to Veta Madre are not included in this estimate.

The following parameters were applied for the calculations:

Oxide mineralization - Veta Madre vein

- Cutoff grade: 100 g/t Ag
- Grade capping at 605 g/t Ag
- Minimum horizontal width of 1.5 m
- Specific gravity of 2.7
- Polygonal method applied on a vertical longitudinal section
- Maximum radius of 50 metres from drill hole or surface sampling line
- All ore above water table and most of it above the 720 m level
- All ore in measured category

Sulphide mineralization - Veta Madre vein

- Same as above for minimum horizontal width, maximum radius and cutoff
- Grade capping at 1,500 g/t Ag
- Specific gravity of 3.0
- Most ore below water table (2550 m level)
- Lead and zinc not indicated as silver equivalent
- All ore in Indicated category

Mineral resources that are not mineral reserves do not have demonstrated economic viability. There are no mineral reserves presently identified on the Real de Catorce property."

The stated mineral resources are not materially affected by any known environmental, permitting, legal, title, taxation, socio-economic, marketing, political or other relevant issues, to the best knowledge of the authors. There are no known mining, metallurgical, infrastructure, or other factors that materially affect this mineral resource estimate, at this time.

Conceptual Mineral Potential

In addition to the Veta Madre veins, more than 20 silver veins have been identified on the Real de Catorce property. Past production and underground development was carried out on most of these veins and limited drilling and surface sampling was completed on some of the veins by Normabec. Normabec and MICON believe the potential to increase silver resources at Real de Catorce is substantial. As such, MICON has estimated the conceptual mineral potential, which is not included in the Resource Estimate, for these other veins and the Veta Madre strike and depth extensions:

However, since the mineral potential of a property cannot be estimated to the same accuracy as a mineral resource, it must be stated as a range. Therefore a factor has been applied to the basecase of minus -30% on the down side and plus 60% for the upside for the estimated mineral potential, in order to state the range for the conceptual mineral potential on the Real de Catorce property. The upside potential is stated to a greater degree because of the lack of information for the 20+ mineralized veins involved and anticipating the possibility that they will be similar in nature to the Veta Madre vein. The upside potential is stated to a greater degree also because the base case mineral potential scenario reflects only the veins which have been identified by on surface or which have had historical mining conducted on them and does not reflect the potential for the discovery of mineralized veins related to the existing veins or hidden veins which could be located during the future exploration phases. The following table states the conceptual mineral potential at Real de Catorce as a range using the base case as a starting point.

Average Vein Average Vein Contained
Length (km) Thickness (m) Silver (Moz)
Minus 30% 82.6
Base Case 1.23 2.4
Plus 50% 177

The conceptual mineral potential model considers a tonnage ranging between 10.5 Mt and 22.5 Mt at grades ranging from 150 g/t Ag to 350 g/t Ag.

It should be noted that the mineral potential of the Real de Catorce property is conceptual in nature and that there has been insufficient exploration conducted on the 20+ veins contained within the mineral potential a mineral resource. It is also uncertain if further exploration will result in the targets being delineated as mineral resources.

It is important to note that during this first drilling program, which lasted only 9 months, the cost of discovery per ounce of silver has been established at 0.15$ . Considering that the company has only been exploring the property for 18 months, such a rate of success at such a low cost is quite spectacular.

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 ppm. 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). QAQC was performed using two silver standards and one blank being introduced alternatively (every 25 samples). Duplicates are being performed by the laboratory.
