Stanmore Expands Coal Resources with US$105 Million Moranbah South Deal

Stanmore Secures Major Coal Asset Adjacent to Existing Projects

Stanmore Resources Limited (ASX:SMR) has agreed to acquire 100% of the Moranbah South tenements from Exxaro Resources for US$105 million, marking a strategic expansion of its metallurgical coal footprint in Queensland’s Bowen Basin. The Moranbah South assets boast 724 million tonnes of measured and indicated coal resources in the Goonyella Middle Seam, widely expected to be premium hard coking coal, a highly sought-after commodity in steelmaking.

The Moranbah South tenements sit immediately adjacent to Stanmore’s Eagle Downs and Isaac Downs Extension projects, offering potential operational synergies. Notably, the Moranbah South coal may be accessed via Eagle Downs’ existing or planned mine infrastructure, subject to further technical and regulatory approvals. This proximity enhances the economics and development prospects of Stanmore’s broader portfolio.

Deal Structure Hinges on Exxaro Consolidating Ownership

The transaction is contingent on Exxaro first acquiring the remaining 50% stake in Moranbah South held by Anglo American’s subsidiary, which Exxaro is set to purchase under pre-emptive rights triggered by Anglo’s sale of its Australian coal assets. Once Exxaro holds 100%, the Moranbah South joint venture will terminate, allowing Stanmore to complete its acquisition.

Completion is targeted by the end of the fourth quarter of 2026, pending regulatory approvals including Foreign Investment Review Board and Australian Competition and Consumer Commission clearances, as well as indicative ministerial consent for the tenement transfer. Stanmore plans to fund the acquisition entirely from existing cash and liquidity, with no requirement for shareholder approval.

Financial and Strategic Upside from Deferred Payment Extinguishment

Beyond expanding its resource base, Stanmore will extinguish up to US$60 million in deferred and contingent consideration payments under a prior 2024 agreement related to access rights over the Moranbah South tenements. This removal of future liabilities improves the financial profile of the Isaac Downs Extension project and adds immediate value to the transaction.

CEO Marcelo Matos highlighted the acquisition as a "significant milestone" that strengthens Stanmore’s platform to deliver future growth. The deal aligns with the company’s strategy to consolidate high-quality metallurgical coal assets in the Bowen Basin, a region where Stanmore has recently demonstrated operational resilience and financial discipline through stable production and a corporate refinancing enhancing financial flexibility.

Resource Estimates Await Independent Validation

Resource figures cited derive from Exxaro’s 2025 Mineral Resources and Reserves Report, prepared under the JORC Code by Anglo American’s competent persons. Stanmore has not independently validated these estimates but intends to commission an independent resource report post-acquisition. The current classification includes 505 million tonnes measured and 219 million tonnes indicated, with a volume mean (VM) of approximately 18.2%. Inferred resources are minimal at 19 million tonnes.

The company cautions that resource estimates may materially change following further evaluation, exploration, and feasibility studies. The Moranbah South tenements include two mineral development licences and an exploration permit, with the potential for underground mining targeting the deeper Goonyella Middle Seam, complementing shallower open-cut targets at Isaac Downs Extension.

Integration Prospects and Next Steps

Stanmore’s acquisition of Moranbah South fits neatly with its existing assets, potentially unlocking operational efficiencies and extending mine life across the portfolio. The company’s recent progress on the Isaac Downs Extension Environmental Impact Statement submission and steady production performance suggest a pipeline of development activity that could benefit from the expanded resource base.

Investors will be watching how swiftly regulatory approvals progress and how Stanmore integrates Moranbah South into its development plans. The independent resource validation will also be a crucial milestone, providing clarity on the asset’s quality and economic potential within Stanmore’s broader strategy.
