Overall Teck goal to commit to 100 megawatts (MW) of alternative energy generation by 2030

Quebrada Blanca

In 2013, QB partnered with AES Gener to guarantee a supply of solar power.

Capacity of 21 MW and delivers a total of 55 gigawatt hours (GWh) per year. Equivalent to 30% of the total energy consumed by Quebrada Blanca.

Andes Solar uses approximately 50,000 solar panels covering an area of 800,000 square metres.

Highland Valley Copper

“In past years, our energy reductions came from energy efficiency projects and involved a small number of people,” said James Myers, Energy Coordinator at Highland Valley Copper (HVC),

“This year, most of our energy and GHG reductions came from reducing equipment wear, minimizing costs or increasing throughput without overloading equipment. By supporting efforts to improve our business, we reduced our energy use and GHG emissions.”

Highland Valley Copper Efficiency examples

Increasing the capacity of a crusher that was causing a backup of haul trucks. The trucks had sat idling, waiting for their turn to unload, or were diverted to a different crusher several kilometers away.

The density in six ball mills was increased, resulting in improved grinding, and aiding metal recovery, but with less energy. 15 HVC energy/GHG saving projects in 2017

Innovation and Technology

Innovation and Technology

Today, the pace of change in mining is getting even faster.

New advancements such as automation and digitalization are increasingly being introduced.

Challenges such as declining ore quality, increasing energy requirements, and climate change create the need for new technological solutions.

12

Low Carbon Economy

Short Term Innovation Focus: Target driven reductions of GHG emissions by transitioning from fossil fuel to clean energy sources and introducing transformative mining and processing technologies to reduce the energy intensity of our production.

Medium to Long Term Innovation Focus• Teck will be establishing aggressive GHG targets going forward: all sources of

GHG emissions will be addressed through a combination of strategies including substitution with clean alternatives, replacement with transformative mining and processing technologies and mitigation with emissions capture systems.

Convictions/Beliefs About the Future• The global economy is shifting to cleaner energy and expects industry to do likewise• The mining industry is focusing on initiatives to drive down our carbon footprint• Step change technologies will be required to achieve future GHG reduction targets

Grassroots

15

Haul Truck OpportunitiesSingle largest GHG opportunity – but one of the most challenging

Trolley Assist• Availability of low-cost, clean power in BC enhances project economics• Can known constraints be overcome?

- Electrical infrastructure – capital cost, maintenance, relocation costs- Mine planning to optimize trolley loads- Payload penalty of pantographs on trucks

Battery Electric• Engaging with OEM’s re development of prototype batteries • Modelling performance in mine simulations • Evaluating impact of autonomous haulage on ideal truck size – smaller

trucks may make BE feasible

Alternative Material Handling• Do innovative technologies such as Ore Sorting positively impact the

feasibility of alternative processes such as In Pit Crushing & Conveying?

16

The Electric Vehicle Prize

• Reduce equipment fuel costs• Eliminate GHG emissions• Eliminate DPM, NOx & SOx emissions

Secondary benefits include:• Reduced maintenance costs & downtime • Improved ergonomics (vibration, noise, etc)

Diesel engines ~44% efficient Electric motors ~93% efficient

17

Energy Storage

The biggest hurdles to battery adoption are energy density and storage volume. Tesla Model 3

~ 150 Wh/kg~ 800 Wh/L

Diesel~ >13,000 Wh/kg~ >10,000 Wh/L

Haul Trucks

A battery electric Haul Truck would require 15MWh per shift.

At current leading energy densities, the battery required would:

• Weight: ~95 tonnes

• Volume: >18M3

• Cost: $3M

Underground Mining

Canadian UG miners such as Kirkland Lake, Glencore, Goldcorp and Barrick are leading the charge towards battery electric equipment.Reduced ventilation demands are a key driver of the UG value proposition.Smaller equipment also makes UG electrification viable today.

Electric Vehicles

Vehicle electrification is growing rapidly across the globe – in many different sectors, from personal vehicles to transit buses to commercial trucking. Battery Electric is widely regarded as the preferred technology – however, Plug-In Hybrid and Fuel Cell Electric technologies also fulfil the market need for extended range beyond the current capacity of battery.

Pick your Power

The EV market is made up of several categories:PHEV – Plug In Hybrid Vehicles are battery-powered, with a fossil fuel-powered generator to extend rangeBEV – Battery Electric Vehicle. FCEV – Fuel Cell Electric Vehicles have a Proton Exchange Membrane (PEM) Cell that utilizes H2 to generate electricity.

18

Build knowledge

Early adoption of electric vehicles is a key element of understanding operation & maintenance processes and design requirements. Engaging with suppliers and operators is another avenue to building knowledge and creating demand awareness with OEM’s.

Collaboration through groups such as the ICMM will be a crucial element of both knowledge acquisition and driving industry development.

Catalyzed by Funding

Government funding is available through a number of sources for projects aimed at reducing Greenhouse gas emissions.

Mining Fleet Electrification

Major challenges need to be overcome to enable mining equipment to be electrified.

Batteries & charging

Significant advancements in battery technology will be required to deliver the power necessary for large, loaded haul trucks to climb out of pits.

With the desire for continuous operation, innovative charging technology would allow trucks to recharge “on the fly” – e.g. trolley or inductive charging.

Industry commitment

Given the relatively low volume of mining equipment sold globally, the cost of the R&D required to design and manufacture equipment specifically for electric power trains will be very high.

Consortia such as ICMM are working to align the interests and efforts of mining companies, OEM’s and technology providers.
