Forward-Looking Statement
  • This presentation contains forward-looking
    statements regarding future events and the
    Company's future results that are subject to the
    safe harbors created under the Securities Act of
    1933 (the "Securities Act") and the Securities
    Exchange Act of 1934 (the "Exchange Act"). These
    statements are based on current expectations,
    estimates, forecasts, and projections about the
    industry in which the Company operates and the
    beliefs and assumptions of the Company's
    management. Words such as "expects,"
    "anticipates," "targets," "goals," "projects,"
    "intends," "plans," "believes," "seeks,"
    "estimates," "continues," "may," variations of
    such words, and similar expressions, are intended
    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.
    Readers are cautioned that these forward-looking
    statements are only predictions and are subject
    to risks, uncertainties, and assumptions that are
    difficult to predict, including those identified
    elsewhere herein and in the Company's Annual
    Report on Form 10-K for the fiscal year ended
    October 31, 2008 under "Risk Factors."
    Therefore, actual results may differ materially
    and adversely from those expressed in any
    forward-looking statements. The Company
    undertakes no obligation to revise or update any
    forward-looking statements for any reason.

Sierra 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.

Block 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.

17
Block 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.

Open 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.

19
Lower 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.

North 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.

Project 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.
