The Colonsay expansion project is a 1.1-million metric tonnes per year (Mtpy) expansion of Mosaic’s potash facilities
located near Colonsay, Saskatchewan, Canada. The Colonsay mine and mill were built in the late 1960s, and have been
operating since 1969.
The expansion project will be conducted in two phases:
- Stage 1 will add 600,000 metric tonnes per year of capacity
- Stage 2 will generate an additional 500,000 metric tonnes per year. Completion of both phases will increase total
production to 3.0 Mtpy
The expansion project is scheduled for completion in 2015.
Hatch has completed prefeasibility and feasibility studies, and is currently undertaking full execution phase EPCM services
to complete the expansion of Mosaic’s Colonsay potash mill. Hatch’s mandate includes the process plant, new main
substation and all other surface supporting facilities.
Hatch has also conducted a logistics dynamic simulation of both surface and underground material handling systems. The
discrete event simulation model was developed to determine underground and surface storage capacity requirements and
skip hoist capacity as well as identify potential ore-handling bottlenecks. The model was used to determine optimal capital
investments required in the material handling and storage systems in the mine.
