Copper, PGMs, iron ore, and other commodities are converted to GEOs by dividing associated revenue for such commodity by the gold price. 4 Calculated as the aggregate Scope 1 and Scope 2 GHG emissions from the Top Mining Asset divided by the total production volume of the primary production (excluding by-products) of such asset. 5 Given the balanced gold and silver production at Guadalupe-Palmarejo, we have converted silver to GEOs, which are included with gold ounces in both emission intensity calculations. 6 GHG emission intensity averages apply to primary production from mining. Such averages exclude mid-stream processing, other than iron ore which includes pelletizing if integrated with a mine.
