to identify such forward-looking statements. In
addition, any statements that refer to
projections of the Company's future financial
performance, the Company's anticipated growth and
potentials in its business and other
characterizations of future events or
circumstances are forward-looking statements.

11Sierra Mojada
- Silver District Sierra Mojada is one of the
early bonanza silver districts of Mexico,
discovered in 1879. Production is estimated at
about 10 million tonnes of high grade silver ore
of sufficient grade to ship directly to smelters
without concentrating, this required a minimum
grade of 500 grams, 16 ounces, silver per tonne,
and multiple kilograms per tonne ore was mined. - Lower South Zone Oxide Zinc Contains silver,
the silver reports to the oxide zinc concentrate
leach residue. Metallurgical investigations will
be conducted to determine a method for extracting
the silver and if it will be an economic
by-product credit. - Note Troy Ounce 31.1 grams and tonne metric
ton 2200 pounds.

16Block Modeling
- Block modeling is a mathematically
sophisticated method of estimating the average
grade and volume of mineralized material using
chemical analyses of samples. The results
provide a three-dimensional model of the tonnage
and grade of a collection of small blocks that
represent the mineralized material as well as
measures of the statistical reliability of the
results for each block. Only those blocks with
relatively high reliability may be used in a
final feasibility study.
17Block Models
- For engineering and geological reasons, the
Sierra Mojada data has been divided into two
zones the North Zone, the area north of the
Sierra Mojada fault and the South Zone, the area
south of Sierra Mojada fault. The South Zone is
subdivided into a lower zone and an upper zone.
We have constructed block models on each of these
zones based on our most current sample data. - Because we have not yet completed drilling in
the area, the results of all block models are
preliminary and are expected to change as more
data is available. The interim results help us
to refine our drilling program and can also help
identify technical questions that must be
answered so that engineering analysis can proceed
efficiently.
18Open Pit Mine Plan
- A Whittle Optimized Open Pit was calculated on
the following Lower South Oxide Zinc Zone block
model volume with all material above the volume
treated as waste. - It is now required that the north and south
block model volumes be drilled at sufficient
drill hole density to quantify and qualify the
mineralized material that can be included in a
feasibility study. - Mineralized material, silver, zinc, copper,
lead, defined in the upper south and north zones
can be mined early in the mining phase and may
significantly improve the open pit mine economics.
19Lower South Oxide Zinc Zone
- Block model results for the lower south zone,
estimate that the zone contains 24,270,000 cubic
meters of material averaging 4.7 zinc and 12.7
grams silver per tonne above a 1 zinc cutoff. - Density measurements of core and rock samples
estimate the in-place density to be 2.54 tonnes
per cubic meter. - The current results are based on 577 diamond
drill holes, 2,886 percussion drill holes, and
8,726 channel samples, for a total of about
108,000 samples, based almost exclusively on
analytical results from the ALS-Chemex laboratory
in Vancouver, B.C.

23North Zone Silver Block Model
- The present model results, based upon 16,604
composite samples from 5,301 drill holes and
other samples and over 30,263 blocks
representing, 5,910,742 cubic meters material,
with high quality drill hole density, determine
an average interpolated drill hole assay grade of
98.0 grams, 3.15 troy ounce, per tonne silver and
2.79 zinc. - Density measurements of core and rock samples
estimate the in-place density to be 2.87 tonnes
per cubic meter. - The model contains an additional volume of
similar size and assay grade, with lower quality
drill density, and has a lower confidence level
than the volume reported above.

27Project Status
- The Lower South Oxide Zinc block model
defines sufficient contained zinc metal to
justify an open pit mine and an acid leach,
electrowinning refinery producing refined zinc
metal, SHG 99.995 zinc. - The metallurgy studies indicate that an
oxide zinc concentrate grading approximately 28
zinc can be produced by Dense Media Separation
and Flotation. - Mine plan studies indicate that open pit
mining is the most economic mining method and
requires that a resource in the Upper South and
North Zones be defined. - Towards this goal we have five diamond
drills, sample preparation and analytical labs.
