Stanmore Resources Ltd reported a strong operational performance in the third quarter of 2026, with South Walker Creek achieving new quarterly records for both ROM and saleable production. The company's deliberate prioritization of stripping and pit preparation earlier in the year contributed to these outcomes. Importantly, the quarter was completed without any serious accidents. Market conditions were supported by supply tightness, particularly from key Russian and Chinese production basins, which drove coal prices higher. The average sales price reached US$163/t, up 6% quarter-on-quarter and 18% year-to-date. This, combined with the company's strong operational performance, supported positive cash flow during the quarter. The company also announced an agreement to acquire 100% of the Moranbah South tenements for US$105 million, adding 724Mt of Measured and Indicated Coal Resources adjacent to Eagle Downs and the Isaac Plains Complex. The company's liquidity stood at US$501 million as of September 30, 2026, providing a strong platform to fund the remaining US$100 million completion payment for Moranbah South.
