MIM decided to develop the Enterprise copper mine deep under its existing operations. Careful planning was vital to minimize disruption to ore production and haulage.

This would be Australia's deepest mine.

We provided engineering, procurement and construction management to access the ore by sinking an internal shaft that connected with an existing shaft, which then reached 1,900 meters into the earth. We called on our worldwide resources and experience to design the backfill plant at Enterprise.

Production began in 2000. Ore production from Enterprise was expected to reach 3.5 million tons per year. The ore was expected to feed the Mount Isa copper smelter for a decade or more.
