Baowu’s Simandou Mine Restarts After Guinea Pay Deal

national collective agreement for the mining sector, signed in February 2025, and to keep current worker job classifications in place for now. The deal also sets fixed pay increases by job grade and says any future reclassification can’t cut existing pay entitlements. Remaining questions over job grading are due to be worked through under Guinea’s labor inspectorate, with a target date of May 20.

Why should I care?

For markets: Execution risk isn’t only engineering.

Simandou is split between BWCS (blocks 1 and 2) and Simfer – a Rio Tinto-led joint venture – on blocks 3 and 4. With Baowu, the world’s largest steelmaker, taking control of BWCS this year, commodity and mining investors will be watching whether both operators can keep construction timelines steady. This episode shows how labor rules, pay tables, and job grading can quickly turn into schedule and cost risks on massive, multi-party projects.

Zooming out: Guinea is standardizing how mines are run.

By explicitly tying BWCS to a national mining-sector agreement and routing unresolved issues through the labor inspectorate, Guinea is signaling it wants more consistent labor practices across operators. For long-life mines, that kind of policy alignment can reduce uncertainty over time, but it can also tighten oversight and raise costs upfront – especially during the build-out phase when delays are most expensive.
