Energy and Greenhouse Gas Emissions

In 2019, we developed an enterprise-level energy management framework for our business, based on the Mining Association Canada’s (MAC) Energy and GHG Emissions Management Protocol. It sets energy reduction targets to help us reduce our emissions intensity over time.

We employ extensive environmental monitoring to track emissions and ensure compliance with applicable laws and regulations.

Energy Intensity

Business unit GJ/oz gold produced GJ/kt material mined
Marigold Mine 6.77 0.02
Seabee Gold Operations 3.04 0.99
Puna Operations2 61.74 0.04
Total3 5.51 0.03

2) Puna Operations produces primarily silver; as such, this metric is reported in thousands of ounces of silver produced.

3) Consolidated energy intensity totals per oz of gold produced exclude Puna Operations.

4) DEFRA emissions factors were used to calculate Scope 1 emissions. All calculations include CO2, CH4, and N2O.

4) DEFRA emissions factors were used to calculate Scope 1 emissions. All calculations include CO2, CH4, and N2O.

5) The Climate Registry Default Emissions Factors (2019) were used to calculate Scope 2 emissions.Calculations include CO2, CH4, and N2O.

6) Scope 1 + Scope 2 emissions. We do not currently report Scope 3 emissions.
