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.
