Australian mining firm BHP has completed 75pc of its 4.15mn t/yr Jansen stage 1 MOP project in Canada's Saskatchewan, but costs for the project's stage 1 have increased by $1bn-1.4bn, the firm said today.
The Jansen stage 1 costs have reached $8.4bn, a 14pc increase from the latest estimate provided in July 2025, partly because of inflation and scope changes. The project's first phase is set to reach first production in mid-2027.
The total investment for Jansen stage 1 was $5.7bn in August 2021, when the project was approved, before increasing to $7bn-7.4bn in July 2025. The most recent cost increase is because of construction hours and material quantities that were not included in previous cost estimates, BHP said.
Jansen stage 2 is 14pc complete. The company expects first production from that stage before 30 June 2031. Production from the second stage will be around 4.36mn t/yr, sending the project's total capacity to 8.51mn t/yr. The project has the potential to reach a capacity of 16-17mn t/yr through two further expansions, BHP said.
BHP expects to provide an updated investment estimate for Jansen stage 2 before the end of BHP's financial year on 30 June 2026.
