Directory

Roper Creek is a Bowen Basin coal project/JV interest in the Middlemount district of central Queensland. Roper Creek is a mineral development licence associated with earlier Roper Creek exploration permits, while Middlemount Coal documentation places MDL 3028 and Roper Creek within the broader Middlemount mining locality. The asset is a project rather than as a producing stand-alone mine. Anglo American’s current Australian steelmaking coal sale package includes an 86.36% interest in the Roper Creek joint venture, with Dhilmar announced as buyer subject to approvals and completion.

Theodore South is a Queensland Bowen Basin coal project/JV interest associated with the Dawson-Moura coalfield south of Theodore. Older Queensland coal references describe Dawson, formerly Theodore South, as a coal deposit about 25 kilometres south of Theodore and 170 kilometres southwest of Gladstone, with Baralaba Coal Measures geology and both open-cut and underground development potential. The asset is not a stand-alone producing mine record in current public material. It is best entered as a non-producing joint venture / coal project interest within Anglo American’s Australian steelmaking coal portfolio, with Dhilmar announced as buyer subject to transaction completion. Mitsui-related interests are historically associated with the Theodore/Dawson South tenements, but confirm current JV party before final database lock. Queensland Government data for EPC 793 lists Anglo Coal (Dawson South) Pty Ltd at 51% and Mitsui Moura Investment Pty Limited at 49%

Non-producing project / JV interest as a stand-alone record. Anglo’s current sale package lists Theodore South as a joint venture interest rather than a producing mine.

The Winchester South Project is an open pit coal mine in Queensland, Australia, currently in the permitting stage. The Queensland Government's Coordinator-General recommended the project proceed in November 2023, and the Draft Environmental Authority was approved in February 2024, though it faces a legal challenge. Construction is expected to start in 2026.

The mine will produce up to 17 million tonnes per annum (Mtpa) of run-of-mine (ROM) coal. This will result in approximately 11 Mtpa of product coal. The product mix over the mine life is expected to be 20% hard coking coal, 37% semi-soft coking coal and 44% thermal coal.

The project will involve the construction of a coal handling and preparation plant (CHPP), a train load-out facility and a rail loop to connect with the existing Bowen Basin coal rail network.

The mine currently has a workforce of approximately 865 people. The proposed Maules Creek Continuation Project would support an increase in the operational workforce to an average of 940 people, with a peak of approximately 1,030.

Production overview - 2023: coal 4355000 t; 2022: coal 3616000 t.
