Burton is an open-cut coal mine which contains three undeveloped open pit deposits.
Burton complex official reopening was held on 4 May 2023. The immediate focus of the project was to invest in the recommissioning of module 1 of the CHPP as well as the Mallawa train loadout and camp facilities. Work commenced on module 2 of the CHPP later in 2023 year, however, this has been paused as the existing capacity from module 1 has proven to meet the coal production needs in the near-term. Completion of refurbishment work on module 2 will be assessed on a production needs basis during the 2024 financial year. |

On 1 July 2022, the Group acquired a 90% interest in the Lenton Joint Venture, which owns the Burton complex. MPC Lenton Pty Ltd, a wholly owned subsidiary of the Formosa Plastics Group, owns a 10% interest in the Lenton Joint Venture which owns the Burton complex infrastructure and Burton and New Lenton tenements.

Summary:
The Burton and Lenton projects area lie within the Permo-Triassic Bowen Basin. Coal seams occur within the Rangal Coal Measures and underlying Fort Cooper Coal Measures which are Late Permian in age. The seams subcrop in the Mining Lease and generally dips at 15- 25 degrees North West at Lenton and mainly 10 to 20 degrees East at Burton with a section in the Ellensfield south pit up to 30 degrees. The main target seams are the Leichhardt and Vermont seams in the Rangal Coal Measures.
The seams split and coalesce significantly along the strike of the deposit. Cumulative seam thickness range between 5m and 10m for all the seams. The drill hole density (core and chip) allows for a high level of confidence in seam splitting, seam thickness, coal quality and location of subcrop lines. The area is structurally complex and the base of weathering is generally between 15m and 25m.
Burton
The Burton deposit is located 120 km westsouthwest of Mackay, Queensland. The ESPN (Ellensfield South (ES), Plumtree North (PN)) deposits occur immediately south of the Burton open cut pits which were mined by Peabody until early 2017. The Isaac Pit is located north of the Isaac River. Burton Mine produced coking and thermal coal for the export market.
The ESPN deposits are located on the eastern limb of the Nebo Synclinorium and target the Rangal Coal Measures (RCM). These coal measures are laterally continuous across the Bowen basin and were mined at the Burton ........
Summary:
In August 2023, the Company announced that the Ellensfield South Pit within the Burton Mine Complex will become the operation’s cornerstone in the near term.
First ROM coal was mined from the Ellensfield South Pit in August 2023 and processed through the Burton CHPP for coal quality analysis and to target trial cargoes for end use customers. It is the Company’s third, and arguably most important opencut mining area producing a higher-yielding coking coal.
The Ellensfield South Pit will be developed as our cornerstone operation in the short to near term, delivering up to 2.4Mt of ROM production per annum for a period of approximately two years, after which the mining fleets will transition into the larger adjacent Plumtree North Pit with a sequencing that will limit the impost of the higher initial strip ratio associated with opening up the Plumtree North boxcut.
Ellensfield South is the Group’s third open-cut mining area and is within the greater Burton Complex, located immediately south of the Burton CHPP. The box cut is still under development and expected to begin producing a higher yielding coking coal late in 1H 2024.
BUMA, the mining services contractor, has mobilised two truck and excavator fleets to Ellensfield South and a third fleet (including labour) has been relocated from Broadmeadow East, collectively targeting steady-state ROM coal production in the order of 240 Kt per month across the Burton complex, from the second half of FY2024.
