Stanmore lifts coal reserves and enhances quality disclosure in 2025 update

Stanmore Resources Ltd ( (AU:SMR) ) has issued an update.

Stanmore Resources has reported total coal resources of 5.1 billion tonnes across its controlled Queensland tenements for the year ended 31 December 2025, alongside run-of-mine coal reserves of 571 million tonnes and marketable coal reserves of 388 million tonnes. The figures, reported under the JORC 2012 Code, reflect updated geological modelling, new exploration data and economic assumptions across multiple sites, while maintaining the underlying technical parameters of prior estimates.

Growth in reserves was driven by the incorporation of the Isaac Downs Extension following a completed pre-feasibility study and maiden reserve in 2025, as well as an expanded reserve base at South Walker Creek after new land access approvals. Stanmore has also enhanced disclosure by adding coal quality data to its resources and reserves summary, offering investors greater transparency on product mix and quality across its coking, PCI and thermal coal portfolio.

The most recent analyst rating on (AU:SMR) stock is a Sell with a A$2.95 price target. To see the full list of analyst forecasts on Stanmore Resources Ltd stock, see the AU:SMR Stock Forecast page.
