Things to Overcome – BEV Mine Design
7
• Regulations – Ontario Air Quality
• Requires 96 cfm/hp – based on diesel equipment underground.
• Uncertainty of Supply, Performance and Cost of BEV fleet
• Supply
– Stay in regular contact with OEM’s on their technology roadmaps
– Create a network of Mining Companies and organizations to share experiences.
• Performance
– Buy units and get first hand experience- we started with a personnel carrier in 2015
– Get OEM’s to perform duty cycle simulations of proposed equipment.
– Run tests at sites to validate performance claims.
– Create a network of Mining Companies and organizations to share experiences.
• Cost
– Have appropriate premium allowance in the project budget based on vehicle class and size.
• Mine Design
• Must design the mine around the BEVs capabilities and needs.
Things to Consider – BEV Mine design
• Take advantage of re-generation
• Limitation – method for releasing energy when fully charged.
• On board vs off board chargers
• Battery swapping vs batteries stay in vehicles
• Battery chemistries
• Safety considerations
• How to maximise life
• Opportunity charging capacity
• How many different chemistries can your mine handle
• Parking and charging locations
• Charging management systems – individual vehicles and for fleet
• Rent or buy batteries
• Battery disposal
• Power quality

Battery Electric Vehicles
Improved Vehicle Characteristics
• No emissions
• Improved performance
• Less heat from vehicles (5x)
• Less noise
• Simpler machinery
• Less wear and tear
• Less maintenance
Benefit to Mining
• Health benefits
• Less particulates – DPM elimination
• Quieter
• Less vibration
• Less heat from equipment
• Less ventilation
• Reduce size & number of ventilation openings
• Less auxiliary fans
• Reduce size of refrigeration plant
• Less heating of mine air in winter (if required)
• Overall lower energy usage and cost
• Improved productivity
• Subjective at present – but mostly due to air quality, vibration, noise and heat benefits

The Raglan Mine – Mining in the Arctic
14
• Aerial or maritime access only
• No connexion to the electric grid or natural gas network
Largest diesel consumer in the Arctic : 100 % diesel
Largest GHG emitter in the Arctic : >100 000 tonnes of GHG
Diesel is the 2nd most significant cost center at Raglan Mine
• Mine Raglan Life of Mine : over 25 yrs as of today
15
3 MW Wind Turbine with cold weather package and fit-for-purpose foundation design
Coupled technologies has further increased fuel displacement
Additional diesel fuel displacement opportunities
• Replace diesel with natural gas
• Hydrogen can be used in other applications e.g. zero-emission transport fuel
• Electric vehicles for surface and underground mining trucks, further reducing ventilation needs
Renewable Energy in Action

The Next Journey : Energy Storage
17
Hatch William’s flywheel GTR 200:
• 200 kW of storage for up to 27 sec
Hydrogenic’s HySTAT 60 electrolyser and
HyPM R200 fuel cells :
• 200 kW of storage capacity for up to 20 hrs
Electrovaya’s Li-Ion battery solution:
• 200 kW of storage for up to 74 mins
Controlled by Hatch’s HµGrid
• Reduce power fluctuations on the grid and
increase penetration level of wind energy
