History
Stanmore grew from a 2009 coal explorer into a major Queensland metallurgical coal producer, backed by majority holder Golden Investments after a 2022 purchase of BHP's mines.
2009-2012: Listing and the hunt for coal
Stanmore Coal listed in November 2009, raising $6 million at $0.20 a share and buying the Comet Coal & Coke assets. Drilling at The Range, a thermal coal (power station coal) project in the Surat Basin, quickly found thick seams. Its first resource of 117 million tonnes in April 2010 beat the 40-50 million tonne target, and it reached 219 million tonnes by July. Mackenzie River, a coking coal (steelmaking) prospect, followed with a 99 million tonne resource.
The company paid for this with new shares: $25.7 million in October 2010 and $24.1 million between December 2011 and January 2012 at $0.74. In June 2012 Sprint Capital of Hong Kong agreed to put in $36.04 million at $0.675, and the company signed a $25 million Credit Suisse facility. Mackenzie disappointed, with coking coal yield averaging only 26%, and in 2013 a Belview concept study was withdrawn because no resource supported it.
2013-2015: Slow years for the explorer
The Range feasibility study, delivered in April 2013, showed a 5 million tonne a year mine, but it depended on rail that had not been built. The Credit Suisse facility collapsed in July 2013. Japanese partners funded much of the drilling: JOGMEC at Clifford and Taiheiyo at Belview. Belview's resource rose to 322 million tonnes and then settled at 330 million tonnes, while Clifford's maiden resource was 370 million tonnes. The Sprint notes converted in June 2015, leaving 13,373,377 shares on issue.
2015-2018: Becoming a producer
In July 2015 Stanmore agreed to buy the Isaac Plains coking coal mine from Vale and Sumitomo for $1, taking on a $32 million rehabilitation obligation. The purchase completed in November 2015. First coal came in April 2016 and the first shipment in May. A December 2016 placement of 27.3 million shares raised $15 million at $0.55.
FY2016 brought a loss of $19.7 million, but FY2017 delivered a $12.0 million profit. Isaac Plains East was approved in March 2018. Stanmore also bought Wotonga South, renamed Isaac Downs, for $30 million. FY2018 profit was $5.966 million, the company was debt free, and it declared its first dividend, 2 cents.
2018-2020: The Golden Investments takeover
In November 2018 Golden Investments bid $0.95 a share. The board rejected it, and an independent expert valued a controlling interest at $1.48-$1.90. The offer closed in January 2019 with Golden holding 25.47%. FY2019 was a record year, with profit of $91.6 million and no debt. Golden then pushed to remove the chair and managing director before withdrawing its requisition in September 2019. A separate Winfield Energy proposal at A$1.50-1.70 lapsed in October 2019.
In April 2020 Golden made a $1.00 on-market bid. After coking coal prices fell, the independent directors recommended acceptance. Golden's holding passed 60%, and in May 2020 the independent directors resigned and Golden's nominees took the board. A 1-for-33 bonus issue was made, and the share count stood at 270,406,341 by the end of 2020. M Resources became exclusive marketing agent, and Marcelo Matos became CEO in November 2020.
2021-2023: The BHP Mitsui Coal purchase
In November 2021 Stanmore agreed to buy BHP's 80% of BHP Mitsui Coal for US$1.2 billion plus a possible US$150 million earnout. It funded the deal with a US$625 million loan and a 7-for-3 entitlement offer at A$1.10 raising A$694.1 million. Golden took up US$300 million of it. The purchase completed on 3 May 2022, and in October Stanmore bought Mitsui's remaining 20% of South Walker Creek and Poitrel for US$270 million.
2022 revenue was US$2,696 million and profit US$727 million. Queensland raised royalty tiers in June 2022. In 2023 the Commonwealth declared The Range's approval lapsed, and the company said it would keep the asset for optionality. Stanmore sold southern Wards Well to Peabody for about US$136 million, completed in April 2024, and paid a special dividend in December 2023.
2024-2026: Prices fall and new projects
Stanmore bought Eagle Downs, completed in August 2024, and rights next to Isaac South. It ceased Mavis Underground operations, paid the full US$150 million earnout in August 2024, and refinanced with a US$350 million term loan. Profit fell to US$191.5 million in 2024, and 2025 produced a loss of US$47.2 million on lower prices, though a final dividend of US 8.9 cents was declared. Isaac Downs Extension reserves of 52 million tonnes were declared and its environmental impact statement was submitted in June 2026.
At 30 June 2026 net debt was US$72 million and liquidity US$408 million. After the quarter, the term loan was upsized to US$250 million with a bullet repayment. On 4 September 2026 Stanmore agreed to buy the Moranbah South tenements from Exxaro for US$105 million from cash. Completion depends on Exxaro acquiring Anglo's 50% and on approvals, and is expected by the end of 2026.
