Stanmore agrees to acquire Moranbah South

27 January 2026 1 4 September 2026 ASX RELEASE Stanmore agrees to acquire Moranbah South “The acquisition of the Moranbah South tenements will represent a significant milestone for Stanmore’s development portfolio, increasing our resource base and strengthening the platform to deliver on our future growth aspirations. The tenements are strategically complementary to Stanmore’s neighbouring projects, particularly Eagle Downs and the Isaac Downs Extension. The significant resources base of Moranbah South is expected to be of premium hard coking coal quality and may potentially be accessed through mine infrastructure at Eagle Downs, should that project be developed. Furthermore, the acquisition of 100% of Moranbah South extinguishes up to US$60 million of deferred and contingent consideration under the 2024 Designated Area Agreement, which enabled access to the Isaac Downs Extension through the Moranbah South tenements. This further enhances the value of the transaction and the economics of the Isaac Downs Extension. Marcelo Matos, Chief Executive Officer & Executive Director Highlights • Stanmore has agreed to acquire 100% of the Moranbah South tenements from Exxaro for consideration of US$105 million. • The transaction is conditional on Exxaro holding a 100% interest in the Moranbah South tenements through the completion of the acquisition of Anglo American’s 50% interest in those tenements pursuant to the pre-emptive rights exercised by Exxaro under the Moranbah South Joint Venture between Exxaro and Anglo. • The Moranbah South tenements contain 724 Mt Measured and Indicated Coal Resources in the Goonyella Middle Seam and are located immediately adjacent to both Eagle Downs and the Isaac Plains Complex, adding further resources to Stanmore’s portfolio of high quality, metallurgical coal assets. • The acquisition provides significant value uplift at Eagle Downs, while also benefiting the Isaac Downs Extension project through the removal of up to US$60 million in deferred and contingent consideration payments.
