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 latest update of the resource estimate on its Real de
Catorce project located in the State of San Luis Potosi,
north-central Mexico.

This update incorporates new drilling information on the Veta
Madre structure as well as surface sampling on the Refugio-Ave
Maria structure. The parameters used by Micon in its June 2008
NI43-101 report were utilized. The main ones are: minimum mining
width of 1.5 metres, cut off grade at 100 g/t Ag, grade capping at
605 g/t Ag for oxides and 1,500 g/t Ag for sulphides. On Veta
Madre, inferred resources were obtained by extending indicated and
measured polygons by an additional 50 metres. On Veta Refugio-Ave
Maria, inferred polygons were drawn by using a 50 metre radius
around channel sample lines. The grades listed above do not include
any polymetallic credits derived from the lead and zinc.
The management of Normabec is quite pleased with the quick
development of the resources at Real de Catorce. The potential to
increase it further remains excellent especially along the
immediate extensions of the past producing veins. It shall be
remembered that drilling so far targeted only one vein; Veta Madre,
although some of the drill holes did intersect the Refugio vein in
a mostly mined out and confined area. The potential of that
structure (Refugio-Ave Maria) is excellent as demonstrated by
surface sampling results published this summer (August 14th
2008).
This NI43-101 compliant resource estimate up date was carried
out in house by Pierre O'Dowd (P. Geo, VP Exploration). Most of the
measured and indicated resource had already been published in a
previous independent NI43-101 estimate (carried out by P. O'Dowd
and audited by Micon International, June 2008). This update mostly
addresses the inferred resources as calculated on longitudinal
sections of the Veta Madre structure as well as the Refugio - Ave
Maria structure. Mr O'Dowd used the same methodology and parameters
as discussed in the June 2008 report.
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.
This press release was reviewed and approved by Pierre O'Dowd
qualified person as defined by NI 43-101 of the Canadian Securities
Administrators.
Normabec is a junior mining exploration company with a portfolio
of advanced projects including: the Pitt Gold project in Quebec and
Real de Catorce Silver project in Mexico.
