BHP restarted negotiations with unions representing approximately 450 workers at its Port Hedland operations.
The talks aim to finalize a new four-year enterprise agreement.
Discussions have continued for more than seven months.
Recent industrial action included an eight-hour work stoppage at the Western Australian site.
Negotiations will resume next week to reach a final deal.
Port Hedland serves as the world's largest iron ore export hub.
A resolution is vital to protect global supply and company revenue.
