Executive Summary

Fuel Ox® with Combustion Catalyst reduces Carbon and Noxious Gas Emissions while reducing Energy
Consumption in Diesel fueled Equipment.
In September 2019, the Essakane mine successfully tested Fuel Ox® in a Water pump achieving a fuel
consumption saving of 9.75%.
The purpose of this trial on large heavy haul equipment, was to confirm savings are achievable across a
full range of mining equipment.
Testing on two Caterpillar 785C Large Haul Trucks and a Caterpillar D-9 Bulldozer successfully
confirmed this, achieving 8.12%, 10.1% for the Heavy Haul Trucks and 32.1% for the Bulldozer.
The mine currently consumes 123,205,882 litres of LFO and HFO annually at an approximate cost of
US$104,982,059.
Whilst demonstrated fuel savings have exceeded 8% it is likely the savings on the HFO power plant, to
be ascertained during the forthcoming trial in July, are likely to be less.
Even so, Fuel Ox® has demonstrated that approximately 16,500 tons in CO2 and 6,151,294 litres of fuel
and more than $4 million annually could be saved with only a 5% average reduction in fuel
consumption across the mine.

Trial and Results
Testing was overseen by Mohammed Barakate of Iamgold and Abraham Collins of ISG/Fuel Ox®.
Equipment tested on:

 • Caterpillar 785c 150-ton Haul Trucks (2)
  o CM 284
  o CM 811
 • Caterpillar D-9 Bulldozer
  o TC 744

Results:

 • CM 284
  o Base (without Fuel Ox® with Combustion Catalyst): 9863.4 liters of fuel used in 83 hours
= 118.84 l/hr.
  o Total with Fuel Ox® additive: 11197.9 liters, 100 hours = 111.98 for an increase of 5.77%
  o Because of the great amount of cleaning of the system that takes place it is best to
concentrate on the end of the period that has utilized Fuel Ox®. Therefore, it is customary
to take the last 5 fill-ups and calculate the difference. In this case it results in 6442 liters,
59 hours = 109.19 or an improvement of 8.12%

 • CM 811
  o Base: 14156 liters, 109.29 hours = 129.53 l/hr.
  o Total: 13621.7 liters. 109.93 hours = 123.91l/hr. which resulted in an improvement of
4.34%
  o Last 5 fill-ups: 6519.8 liters, 116.43 hours = 116.43 or an improvement of 10.1%

 • TC 744 (Cat Dozer)
  o Without Fuel Ox® additive: 2853 liters, 64 hours = 44.58 l/hr.
  o Total with Fuel Ox®: 2390 liters, 79 hours = 30.25 l/hr. for an improvement of 32.14%
  o There is no need to break down to the last five fill-ups in this case as this is indicative of
Fuel Ox with Combustion Catalyst not only improving combustion but also cleaning the
fouled portions of the engines- in this case it is a likely injector or two that was keeping
the machine from achieving peak efficiency. This will commonly happen when heavy
equipment is not using optimum fuel and there is no additive to keep deposits from
forming.

Conclusion:
The test on these three pieces of equipment is indicative that using Fuel Ox® with Combustion Catalyst
on a regular basis will help IAMGOLD achieve their aim of reducing their Global Carbon Footprint
whilst saving the company money.
Not only is a monetary saving achieved but as demonstrated through many other trials across the globe
there would be savings in
 • SO3
 • Soot

 • PM’s
 • CO
 • CO2
 • NOx
 • SOx
Which will result in a reduction of damaged parts, smoother, cleaner running engines and increased
asset life resulting in lower Capital Expenditure.
If used mine-wide, annual fuel savings, with only a 5% reduction in consumption could exceed
US$4,000,000. This, before any consideration of less maintenance issues with bad fuel, failed injectors,
cleaner filters, etc., all of which equate to further savings. Taking into effect all these things the real total
benefits are likely $6-8 million annually.
The Fuel Ox® with Combustion Catalyst – based on the sole fact it increases the combustion – literally is
burning more of the fuel which directly results in less emissions. In fact, soot is decreased by 50-70%,
CO2 by 15-20%, NOx by about 10% and SOx by about 10%. All these lead to a cleaner environment and
the potential procurement of carbon credits as well.
In conclusion, if IAMGOLD were to use Fuel Ox® in all its Diesel, both HFO and LFO, fuel across all
mines, there would not only be a financial benefit, but it would also enable the company to achieve its
motto of Zero Harm, leading to a cleaner and healthier environment.

Footnote: There is an ongoing test with Infinity Lubes™ which will be covered in a subsequent report, but
which has already shown significant improvement in the operation of the drill rigs.
