ST-BRUNO, QUEBEC (FRANKFURT: N6M) ("Normabec"), through its
wholly owned Mexican subsidiary Minera Real Bonanza S.A. de C.V.
("MRB"), is pleased to announce more results from its ongoing
surface and underground drilling programs on the Veta Madre
structure at the Real de Catorce project in north-central
Mexico.
High grade intersections continue to be pulled both from the
surface drilling and from the underground drilling on Veta
Madre.
Underground drilling on the Purisima oreshoot below the
historical mine workings continue to confirm bonanza grade silver
as well as important base metal credits. The oreshoot has been
traced so far for 200 metres laterally and 200 metres vertically.
It remains open at depth and to the west. The following table shows
the latest assay results from the depth extension ot the Purisima
oreshoot:
Hole From To Width Ag Pb Zn
(m) (m) (m) (g/t) % %
VMP-10 258.32 264.00 5.68 393 1.23 1.79
At today's metal prices, such an intersection has a gross metal
value of approximately 230$ per tonne. To date, the gross metal
values of the intersections returned along the depth extension of
the Purisima oreshoot have ranged from 157$ per tonne (VMP-9) up to
626$ per tonne (hole 1016). The average of the seven intercepts
received and released so far is 360$/tonne (825 g/t or 24 oz/t Ag
equivalent).
At surface, systematic drilling of the Veta Madre structure
continues to yield ore grade mineralization. In-fill drilling is
being performed at 40-50 metre spacing, from surface down to the
150 metre level approximately. The following table shows the most
recent assay results obtained from surface drilling along a
productive portion of the Veta Madre structure:
Hole From To Width Ag
(m) (m) (m) (g/t)
VMS-5 68.00 69.90 1.90 138
VMS-7 87.85 89.05 1.20 271
and 93.20 94.60 1.40 169
VMS-8 41.00 44.15 3.15 374
VMS-9 64.40 70.65 6.26 346
VMS-10 52.60 57.35 4.75 193
Average grade of the first ten drill holes on the central
portion of the Veta Madre structure is 284 g/t Ag (124$/tonne).
This is a significantly increase over the 189 g/t Ag obtained from
the surface sampling program. This program is targeting the near
surface, oxidized portion of the vein which carries little base
metals. It is important to note that the Veta Madre structure has
historically been accessed (but only locally mined out) for its
entire length from numerous levels developed every 40 metres. The
near surface drilling area is located in the center of these
underground workings and limited expenditures will be required to
rehabilitate them once a production decision is taken.
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.
