Altair and BHP Enter Mediation Over Olympic Domain Project Rights

Background of the Dispute

Altair Minerals Limited (ASX – ALR) has updated shareholders on its ongoing legal dispute with BHP Olympic Dam Corporation (ASX – BHP) concerning the Olympic Domain Project in South Australia. The project area adjoins BHP’s Oak Dam Deposit, a significant copper and gold resource. BHP has sought to use part of Altair’s tenements for infrastructure development related to Oak Dam, prompting Altair to file a formal legal response opposing this application.

The dispute is currently before the South Australian Wardens Court, where Altair contends that BHP has not met the legal burden of proving that Altair’s exploration rights and interests will remain unaffected by BHP’s proposed use. Altair highlights potential material diminishment to its rights, including impacts on exploration activities, increased expenses, access difficulties, and native title obligations.

Court Proceedings and Mediation

Following Altair’s comprehensive response filed on October 29, 2025, the scheduled court hearing for November 12 was vacated by consent of both parties. This move allows the companies to engage in private mediation aimed at resolving aspects of the dispute without further court intervention. The mediation is set to occur on or before December 12, 2025, with the matter re-listed for a hearing on December 22 if no agreement is reached.

Altair has committed to approaching the mediation in good faith, signalling a willingness to negotiate while maintaining a firm stance on protecting its exploration rights. The company emphasises the broader importance of safeguarding junior mining companies’ rights in Australia’s resource sector, noting that entrepreneurial exploration efforts underpin the industry’s future growth.

Strategic Implications for Altair and the Industry

While the legal process unfolds, Altair continues to focus on advancing its Greater Oko Project, demonstrating a dual approach of defending existing rights while pursuing new opportunities. The outcome of this dispute could set important precedents for how junior miners negotiate infrastructure access and development alongside major resource players like BHP.

For investors and industry watchers, the case highlights the delicate balance between large-scale mining operations and the rights of smaller explorers. The resolution may influence future negotiations and regulatory frameworks governing resource development in Australia.
