Description

A multi-year project to design, construct and operate/maintain a large-scale slope depressurization program at an open pit mine.

Our Role
Depressurize a clay layer located within the pit wall stratigraphy, thereby allowing the excavation of the overburden slopes to a stable geometry. The project will facilitate a considerable expansion of the mine, and extend the life of the mine by 10 to 15 years. GAIA Contractors, in collaboration with Golder Associates Ltd., provided a phased approach with groundwater extraction wells installed as pit benches are made available.
