Kutcho Copper Corp. provide results from a Greenhouse Gas ("GHG") intensity study completed by Environmental Resource Management (ERM) based on the Company's 2021 Feasibility Study on its high-grade copper -- zinc development project located in north-western British Columbia. The simplest measure for carbon intensity requires estimating the average annual production of GHG emissions from the burning of hydrocarbons such as LNG, diesel, and explosives and dividing that by the produced copper metal (cradle to gate calculation).

On this basis the carbon intensity for the Kutcho Project has an average operational annual GHG of 1.94 kg CO 2 e/kg Cu. Figure 1 shows publicly available information for operating mines in British Columbia in 2018 in comparison to the Kutcho Project. The Kutcho Project average operational annual GHG lies below the median of these other operating mines.

The average operational annual GHG per unit of copper does not give the full picture of carbon intensity. The Kutcho Project also produces significant amounts of zinc, silver and gold and, as such, a GHG intensity measured against copper equivalent production is more appropriate. The average operational annual GHG per pound of copper equivalent metal produced is 1.1 kg CO 2 e/kg Cu eq .

BC based comparative information is not available for this equivalent metal measure.
