The Idaho-Maryland Mine Project includes many design features to minimize emissions, reduce greenhouse gases and protect air quality.

Robust modelling by independent air quality experts shows no impact to public health from project.

The project is designed to produce gold with 90% less CO2 than the industry average.1

Shaft Access

The Idaho-Maryland Mine is accessed by vertical shafts. The mine elevators and hoisting of broken rock is powered entirely by electricity. This access method is much more energy efficient than hauling by trucks via ramps (a method commonly used in other underground mines).

The shaft access and underground tunnels provide the ability to incorporate engineering controls to ensure dust is not exhausted by from the underground mine ventilation system.
