For Touquoy,
"The pit is to be developed in two stages with a cutback to the final pit limits in Year 3. The final pit will be 760 m long x 400 m wide with a maximum depth of 140 m. Waste-to-ore ratio over life-of-mine is 2.6:1"
Significantly better than the "Super pit", Significantly worse than CH.
The Ch strip ratio smells funny.
