Problems Associated with Traditional Haul Road Construction

  • High costs for construction materials such as aggregate
  • Dust production, this lowers productivity as well as causing issues with safety

and creating a health risk

  • Potholes and wash boarding that occur will increase the risk of RAC events and

the need for maintenance

slide-6
SLIDE 6

Problems Associated with Traditional Haul Road Construction

  • Rolling Resistance
  • Truck haulage costs can account for up to 50% of the total
  • perating costs incurred by a surface mine, and any savings

generated from improved road design and management benefit the mining company directly as a reduced cost per ton material hauled (Thompson & Visser 2003).

Problems Associated with Traditional Tailings Storage

  • Dam failure – resulting in sudden release of massive amounts of

potentially toxic contaminates into the environment.

  • Leaching – problems such as Acid Mine Drainage, etc.
  • Dry Stack – wind and water erosion.

Because EarthZyme uses the clay as the natural binder, which remains in the soil indefinitely, it produces the long term effects that are desired

EarthZyme Soil Stabilization

Driven By Innovation – Partners in Performance

EarthZyme reacts permanently with the clay in the soil to produce long-term stabilization. Other products often glue the clay particles together Once the glue is gone….so are the results of the stabilization process

A study conducted on an EarthZyme haul road application at an open-pit coal mine in Xilinhot, China, by Shenhua Beidan Shengli Energy Co. Ltd. showed a substantial decrease in operational and maintenance costs. After a successful demo road in 2013 Shenhua has used the technology on all new haul road builds ever since.

17.4% Reduction in Diesel Fuel Consumption

  • Over 1 million gallons of fuel saved
  • ver the duration of 1 year. Results

indicated that the fuel consumption dropped from 5.9 million to 4.9 million gallons in that timeframe, on a 10 km stretch of stabilized road.

3.6 Million USD Cost Reduction in Fuel Expenses

  • In 2014, the cost of diesel fuel in

China was $3.60 USD per gallon, meaning that approximately $3.6 million in USD was saved in fuel costs in that timeframe.

CO2 Emissions Reduced by Over 10,000 Tons/Year

  • According to the EPA, diesel fuel

emits 10.1kg of CO2 per gallon. By saving 1 million gallons of diesel fuel, emissions were reduced by 10,100 metric tons.

Reduces maintenance costs ✓ Reduced need to grade treated roads ✓ Reduction in watering requirements Non-corrosive and environmentally friendly ✓ Will not cause rust on vehicles or application equipment ✓ No adverse impact on roadside vegetation

Dust Stop Liquid Concentrate (DSLC)

Driven By Innovation – Partners in Performance

Increased water resistance resulting in better performance in all weather conditions ✓ Reduction in maintenance requirements as a result of wet weather ✓ Does not get slippery when wet – can be applied to ramps! Long lasting results Cost Competitive with chlorides BOEING D6-17487 Revision T Certified ✓ Safe for use on airfields ✓ Won’t affect sensitive aircraft materials

Cost Benefit Analysis

Water versus Dust Stop Municipal Blend

slide-23
SLIDE 23

How it works DSMB is not Hygroscopic! Unlike Chlorides, DSMB does not rely on ambient moisture in the environment

  • Unique blend of materials utilizes the

functional properties of sugars, starches and minerals.

  • Bind and harden any loose particulate

matter decreasing dust in road surfaces.

  • Reduce road surface issues both during and

after rain.

  • Incorporated sugars compete for water

making it less available to bind with other soil molecules.

slide-24
SLIDE 24

How it works

  • Provide structural support and added

road stability.

  • Will re-set once road surfaces dry, re-

binding any loose materials.

  • Not adversely affected by heavy rain,

yet very effective and long lasting in dry weather.

  • No adverse effects on the environment
  • r vehicles using the road due to its

non-corrosive properties.

Easy Adoption by Any New Customer!

Dust Stop Municipal Blend (DSMB) is applied with standard equipment used to build and maintain roads.

Emulsion – The Delivery System

  • An emulsion consists of tiny droplets of polymer suspended in water
  • Polymer emulsions contain 40-60% polymer solids (DSLC = 56%)
slide-32
SLIDE 32

Driven By Innovation – Partners in Performance

After application of the emulsion to the roadway, the water evaporates and the polymer particles pack closely together to form a continuous film.

slide-33
SLIDE 33

Driven By Innovation – Partners in Performance

As more water evaporates, the particles undergo deformation to form a void- free solid structure, which is still mechanically weak.

The ability of Dust Stop to coalesce into a durable, strong, water resistant film allows it to encapsulate all of the dust generating material to prevent it from becoming airborne particulates

Vale Wind Tunnel Test

  • Wind tunnel testing to simulate and monitor particulate emissions in train

wagons (open rail car transportation of ore).

  • Testing carried out by the Federal University of Espírito Santo, Vitória, Brasil,

in accordance with procedures developed by Vale.

  • Testing procedure simulated a 12 hour transportation route under open

conditions, with UV simulation added.

  • Moisture content, as well as weight of the ore before and after the test were

measured.

  • Applied DSLC onto tailings

stockpiles to control erosion from wind and rainfall.

  • The dust created from these piles

raised the risk of health complications in nearby communities, DSLC remediated this issue and is still in use today.
