Stanmore Resources Limited (ASX: SMR) released this news to the market on 4 Sep 2026, and there was, truth be told, a fair bit packed into it. The Company has agreed to acquire the Moranbah South tenements from Exxaro Resources Limited for US$105 million in cash. The tenements sit in Queensland’s Bowen Basin, right next to Stanmore’s own Eagle Downs and Isaac Downs Extension projects.

This ASX Stanmore Resources Moranbah South Acquisition matters for anyone following the metallurgical coal sector. The deal is still conditional, but it points toward a meaningfully larger resource base for Stanmore, sitting almost on the doorstep of assets it already controls.
ASX Stanmore Resources Resource Upside: The Headline Numbers
The scale of Moranbah South is the part worth sitting with. It adds 724 million tonnes of Measured and Indicated coal resources, all in the Goonyella Middle Seam, a seam which is known to produce premium hard coking coal.
Moranbah South Coal Resources, 2025
| Category | Tonnes (Mt) | Volatile Matter (%) |
| Measured | 505 | 18.5 |
| Indicated | 219 | 17.6 |
| Inferred | 19 | 16.9 |
| Total | 743 | 18.2 |
These numbers are based on Exxaro’s Consolidated Mineral Resources and Mineral Reserves Report 2025, 29 Apr 2026. Stanmore has indicated that neither Exxaro nor Anglo American has verified or endorsed the figures in this regard. Once the deal closes, the Company intends to commission its own independent resource report.
Driving the ASX Stanmore Moranbah South Deal: Transaction Mechanics
Getting to this point required a few moving parts. Exxaro currently holds only half of Moranbah South, through a joint venture with Anglo Coal (Grosvenor) Pty Ltd, a subsidiary of Anglo American. Anglo agreed to sell its Australian coal assets to Dhilmar QLD Pty Ltd, and that sale triggered pre-emptive rights under the joint venture agreement.
Exxaro has exercised those rights to buy out Anglo’s remaining half. Once that step is done, Exxaro will hold full ownership of the Moranbah South tenements, and the joint venture will formally close. Only then can Stanmore’s own purchase from Exxaro proceed.

Transaction Snapshot
| Item | Detail |
| Buyer | Stanmore Resources Limited (ASX: SMR) |
| Seller | Exxaro Resources Limited (JSE: EXX) |
| Interest acquired | 100 per cent of Moranbah South tenements |
| Consideration | US$105 million cash |
| Funding source | Existing cash and liquidity |
| Shareholder approval required | No |
| Expected completion | Before the end of Q4 2026 |
Stanmore plans to fund the Consideration from its own cash balances and liquidity. That means no shareholder vote, which ought to keep the timeline pretty tidy once the regulatory conditions are out of the way.
Why the Tenements Fit: Synergies With Eagle Downs
Moranbah South is an underground project, made up of two mineral development licences, MDL 277 and MDL 377, plus an exploration permit for coal, EPC 548. Location is really the story here. The tenements border both Eagle Downs and the Isaac Downs Extension.
Moranbah South Tenement Overview
| Tenement | Type |
| MDL 277 | Mineral Development Licence |
| MDL 377 | Mineral Development Licence |
| EPC 548 | Exploration Permit for Coal |
Subject to further technical studies and regulatory sign-off, Stanmore expects the resource could eventually be accessed through existing drift infrastructure already built at Eagle Downs. That would avoid the cost of standalone infrastructure for Moranbah South, assuming Eagle Downs itself gets the green light for development.
There is a second, quieter benefit buried in the announcement. Stanmore had earlier secured rights, under a 2024 Designated Area Agreement, to apply for a mining lease over part of this same ground.
Owning the tenements outright now removes up to US$60 million in deferred and contingent payments tied to that earlier deal, which directly improves the economics of the Isaac Downs Extension.
Balancing Resource Upside With Deal Conditionality
I keep coming back to one detail in this release: Stanmore is buying an asset it does not yet fully control from the seller. Exxaro still needs to complete its own purchase from Anglo before Stanmore’s transaction can close. That is not unusual in resources deals, but it does mean the timeline runs on someone else’s schedule as much as Stanmore’s own.
Regulatory approvals add a further layer. Foreign Investment Review Board clearance, ACCC consideration, and ministerial approval for the tenement transfer all sit as conditions precedent. None of these looks unusual for a transaction of this size, but together they explain why completion is only guided to before the end of Q4 2026, rather than a firmer date.

Future Direction and Impact on Stanmore’s Growth Strategy
Impact on the development pipeline is really where this deal earns its significance. If Eagle Downs eventually moves into development, Moranbah South’s resource could be accessed through the same infrastructure, without Stanmore needing to fund a separate access route from scratch.
There is also a funding impact worth noting. Removing up to US$60 million in deferred and contingent payments reduces future cash obligations tied to the Isaac Downs Extension, freeing up capacity elsewhere in the portfolio. See more ASX mining updates on Colitco.
Investors tracking the ASX Stanmore Resources Resource Upside should watch two things from here. First, whether Exxaro completes its purchase from Anglo on schedule. Second, the outcome of Stanmore’s own independent resource report, expected once the Transaction closes.
