This is the ultimate pit shell design for the portage pit which will mine the portage orebody. Mining takes place on 7-m-high benches with a final bench height of 21 m between catch benches, which vary between 8 m and 14 m wide depending on the sector. The geotechnical sectors and pit slope properties are summarized in for the three deposits at Meadowbank.

Double-lane ramps are 28 m wide to accommodate 150-ton-class mining trucks (CAT 785), and single-lane ramps are only to 18.8 m wide. Ramp gradients are at 10%. The long, narrow Portage pit will have final dimensions of 2,237 m long by approximately 345 m wide and 134 m deep.
