Greenhouse Gas And Gold Mines Emissions Intensities

2021-8-20  At underground mines, there was a significant decline in the grade of ore processed, from an average of 3.25 grams of gold per tonne in 2019 to 2.64 g/t in 2020. Emissions increased by a modest 2% at those mines, but with less gold produced per tonne of ore processed, emissions intensity on a per ounce basis increased far more.

Greenhouse gas emissions and production cost footprints

2020-9-10  Gold grades in Australian mines have been declining and are forecast to decline a further 44% by 2029. Without taking measures to reduce GHG emissions, such a decline would lead to a 49%, 32% and 34% increase in the GHG emissions footprint per ounce for OP, OP & UG and UG mines, respectively.
