SIZING THE CHALLENGE
9
HAULING ACCOUNTS FOR UP TO 50% OF MINE ENERGY
28,000 large mine hauling trucks
x
900,000 liters of diesel per truck
per year
= 68 million tons of CO2e per
year

TRUCKING DEMAND ON TRACK TO INCREASE 125% BY 2050
• Commodity Demand + 50-100%
• Ore Quality - 50-100%
• Trucking Need +25%

TRUCKING NEEDS TO BE 108% MORE EFFICIENT BY 2050
DECARBONIZATION OPTIONS
13
THREE GENERAL SOLUTION SETS
14
BIO-DIESEL
+Considered Carbon-Neutral
+B20 can run in diesel engines without
modification
+Reduces CO, SOx and Particulates
- Higher concentration blends may
damage engines
- Supply Chain Concerns in consistency
and environmental impact
SUPPLY UNCERTAIN BUT FUEL IS FUNGIBLE WITH DIESEL AT LOW % BLENDS
15
NATURAL GAS
+Demonstrated applications in medium &
heavy duty trucks
+Reduces CO2 emissions by 20-25%*
+Dual-Fuel blending has been proven to
work
- Emissions reduction potential depends
on upstream supply chain
- Retrofitting required to run trucks
entirely off LNG
- On-site cryogenic storage tanks
required
READILY AVAILABLE AND PROVEN FOR TRUCKS BUT NOT HAULERS
16
TROLLEY-ASSIST
+With grid power, can reduce CO2 emissions by up to
30% from reduced diesel
+Trucks move faster up-hill
+System becomes cleaner as power supply becomes
cleaner
- High capital cost
- Fixed asset*
- System downtime will impact mine operations
VALIDATED RETROFIT TECHNOLOGY FOR SPECIFIC APPLICATIONS
17
IN-PIT CRUSHING & CONVEYING
+Continuous operation
+Low OPEX
+Fully electric allows operations to become
cleaner with supply
+Multiple designs available
- High capital cost
- Fixed asset*
- System downtime will impact mine
operations
- Best for new mine design, not retrofit
- Ramp slope less than 10 degree
WELL-ESTABLISHED METHOD FOR BULK MATERIAL TRANSPORT AT LOW COST
18
ELECTRIC TRUCKS
+No on-site emissions
+Supply of energy storage can enable more
renewables & load-shifting
+Potentially much lower OPEX
+Integration with Trolley-Assist
- Requires more down-time for charging
- Not commercially available at scale
- Higher CAPEX than diesel haulers
EXCITING BUT NOT AVAILABLE AT SCALE
19
HYDROGEN FUEL
+No on-site emissions
+Supply of energy storage can enable more
renewables & load-shifting
+Higher energy density than batteries
+Provides all the flexibility that traditional fuels provide
- Not commercially available
- Higher CAPEX than diesel haulers
ALSO EXCITING BUT NOT AVAILABLE YET
STRATEGIES FOR MEETING EMISSIONS TARGET
21
IMMEDIATE SHALLOW CUTS ONLY BUY A FEW YEARS
DEEP CUT NEEDS TO HAPPEN BY 2028 - 2033
22
THREE BROAD STRATEGIES
1.Expand the Problem
2.Over-Deliver on Select
Assets
3.Accelerate Technology
Readiness
