Proof of Concept under harsh conditions

The Claycrete & Kalfoss Methodology has been put to the test for approx. 15 years primarily inAustralia, Asia and more recently in North Africa.

Kalfoss and Claycrete have been implemented in 1000 of KMs of roads that have been in useconstantly for the last 15 years and still going strong, enduring wear and tear 24/7/365 by Australia’sfamous 110-180 tonne Road Trains.

Past and Present Claycrete customers include:

RioTinto, Murchison Metals, Mittal Steel, BHP Billiton, Newmont Mining…..

The Claycrete product range;CCI, CCII, CCIII and Kalfoss

CCI, CCII and CCIII improves road building materials that contain clay. Many types of gravels availablethroughout the world are high in clay content, which causes problems and structural failures in wetconditions.

Claycrete resolves these problems by altering the Clay particles on a molecular level, permanentlychanging the Clay into a environmental friendly binder of Soil materials, increasing soil pavementstrength/barring ratios between 150% - 525%.

Kalfoss bonds and improves the strength of Limestone/Calcareous/Gypsum materials with similar resultsas the Claycrete product range. Kalfoss binds sub-base and base course materials to be used directly asan All-Weather pavement or as a preparation for a Bitumen or Asphalt seal.

The Claycrete product range allows our offering to be applicable toapprox 80% of the worlds Mining/Oil/Gas sites.

Claycrete benefits summary,Industry independent:

•Due to the ever-increasing Worldwide shortage of good quality gravel materials, Claycrete is able tosupply a superior quality and cost alternative to the use of good quality gravel when constructing roads,by Claycrete´s ability to use lower quality in-situ materials.

•Materials/soils once treated by Claycrete/Kalfoss will no longer attract or hold water thus allowing theClay/Lime particles to act as nature’s natural binder, resulting in a tight well-bound permanentpavement and a first class ‘All Weather road’, however constantly re-workable should damage occur.

•A liquid chemical additive, easily and safely incorporated in pavement construction and does notrequire any specialised machinery.

•The method does not rely on an introduced “Residual Product” therefore leaching cannot occur.

•Is environmentally friendly, neither harmful to Flora, Fauna or water catchments areas.

•Implementation of Claycrete is in most cases the easiest, safest and most cost effective form of roadconstruction.

The Mining Industry challenges

The Mining industry is burdened by high start-up costs, high access & haul road construction costs,heavy equipment costs coupled with high ongoing maintenance costs in large due to ill constructedinfrastructure solutions and poor material availability and/or material selections.

Causes of excessive vehicle maintenance can be attributed to;

•Poor, slippery/muddy road pavements full of potholes andcorrugations.

•Incorrect material selections, design and constructed methods.

•Pavements with loose powder materials causing excessive dust.

•Poor or Non-existent Driving Methods/policies

Poor pavements results in a number of maintenance issues;

•Tyre wear

•Fuel consumption

•Excessive Shock absorber wear Wheel bearings

•Suspension failures Chassis fractures

•Differential failures Gearbox failures

Driver Safety

There is no need to overstate driver stress impact when travelling on a properly constructed pavement versus a poor and illconstructed pavement.

14

The Mining Industry & Claycrete

The Claycrete Methodology and products will result in an infrastructure solution tailored to:

•Increase Tire life 10-35% (very dependable on local pre existing conditions)

•Increased vehicle efficiency; increased haulage tonnes.

•Increased road safety.

•Increased road strength, will carry much heavier traffic!

•Increased Road Dependability resulting in Decreased down time.

•Lower overall vehicle maintenance costs

•Lower road maintenance costs.

•Lowered Fuel costs

•Reduced slipperiness due to Mud, resulting in lessened Environmental impact.

•Reduced dust, resulting in lessened Environmental impact.

15

The Mining Industry and Claycrete,continued

Travelling on an uneven bumpy road full of potholes, will result in unnecessary stress to theentire vehicle causing it to operate inefficiently and expensively.

Tyre WearExcessive tyre wear is caused by lack of good traction andwheel spinning on a mud covered or protruding stone coveredpavement as well as sidewall damage from climbing in andout of potholes. Dry dusty/powder pavements with protrudingstones and rocks cause excessive damage to sidewalls andtread as well.

Fuel ConsumptionExcessive fuel consumption is due to two major problems;wheel spinning due to slippery surface and the effort of thetyre continuously running uphill as it tries to climb out of itsown pavement indentation while pushing a bow-wave of mudor dust.

Driver SafetyThere is no need to overstate driver stress impact whentravelling on a properly constructed pavement versus a poorand ill constructed pavement.

Drive TrainExcessive stress due to the driver having to continually changespeed and direction on a very poor road, as compared to asmooth vehicle movement on a even pavement.

Suspension, Shock Absorbers and Wheel Bearings etcAll these components take a pounding while travelling on a badlycorrugated, potholed pavement, which is exaggerated in wetmuddy conditions.

ChassisAn uneven, badly constructed and badly worn pavement willcause continuous excessive stress resulting in body fractures.

The Oil/Gas Industry and Claycrete

The Oil and Gas Industry is faced with heavy exploration cost and largeupfront investments in processing plants, pipelines and Well-sites, all ofwhich require Good access roads.

The road infrastructure is the lifeline of any Oil and Gas project. It isessential that these access roads are reliable and trafficable in ‘AllWeather’ conditions. Reliable airstrips are also essential in remotelocations.

Process plant roads and airstrip may be required to be sealed/pavedsurfaces (Asphalt, Bitumen or Chip seal etc), the Well-roads or PipelineRoads are most likely unpaved/dirt roads. These Well-Roads need tobe maintained in order to guarantee accessibility for maintenance,surveillance etc.

17

How the Oil & Gas Industry benefits from aClaycrete Solution

Claycrete´s ability to improve the strength of available materials, in both Sand Desertenvironments as well as Wet Clay based environments provides the Oil & Gas industry withreliable All weather trafficable roads.

Claycrete Offers the Oil & Gas industry a road solution that is able to utilise local materials in awide range of environments; easily translated into reduced costs in the initial construction ofprocessing plants and Well-heads coupled with reduced maintenance cost while increasingthe reliability of their supply roads as well as generally increased driver/road safety during plantoperations.

General Road Construction and Claycrete;The Greatest savings

Claycrete has been used in major national asphalt highways, minor sealed and un-sealedroads as well as in local government airstrips.

Claycrete´s standard method of creating a base course 20cm deep allows for direct usage asan unsealed dirt road, perfectly trafficable in heavy rains or in droughts.The base course also serves as a perfect foundation for sealing with Asphalt, Bitumen, Chipseal etc.

Using Claycrete in the construction of sealed roads enables The Greatest Savings of theClaycrete Methods due to the significant savings in sealing costs, which are a direct result ofthe reduced thickness needed when sealing on top of a Claycrete foundation.

When sealing a road (Asphalt, Bitumen, Chip-seal etc) built using Claycrete/Kalfoss, theAustralian Standard of using a 2.5cm seal is possible.

Claycrete sealed roads have an expected lifespan of 15-20years, under harsh conditions.
