Snapshot	Byerwen Project has moved through to completion of the first stages of construction and mining operations for the South Phase in 2017. The North Phase have progressed through the statutory approvals and landholder compensation processes and are awaiting grant. In the interim, Byerwen has commenced initial planning for the North Phase expansion. Once fully operational, the Byerwen Mine will produce up to 10 million tonnes of hard coking coal per year with some thermal coal.

Deposit type

• Sedimentary

Summary:

The project is located within the Northern Bowen Basin which is characterised by typical basin fill fluvial (and some marine) sediments, comprising mudstones, siltstones, sandstones and coal seams.

The Bowen Basin contains Early Permian rocks of the marginal marine Back Creek Group, Late Permian coal-bearing (non-marine) strata of the Blackwater Group, fluviatile sedimentary rocks of Triassic Rewan Group, and overlying Tertiary basalt and sediments of the Suttor Formation and Quaternary alluvium deposits.

Coal Measures
The Blackwater Group contains Permian age (i.e. 248-290 million years) coal measures. The Rangal Coal Measures represent the uppermost unit of the Blackwater Group, and although attaining a maximumthickness in the order of 220 m, are generally less than 100 m thick in the project area. Coal from the Rangal Coal Measures may be mined during the latter half of the mine life. The main seam of interest in the Rangal Coal Measures is the Leichhardt seam, a correlation of the Upper Newlands seam which is between 4.5 and 6.5 m thick in the surrounding vicinity.

The Fort Cooper Coal Measures, the central unit of the Blackwater Group, do not contain target coal seams in the project area (based on resource drilling undertaken). However, current coal extraction from the FCCM may be undertaken should suitable seams be identified during operations.

The Moranbah Coal Measures (MCM) are the lowermost formation of the Blackwater Group and represent the main stratigraphic unit of interest in the project area. This unit is approximately 290 mthick in the project area and contains up to seven persistent coal seams. The principal seams of economic interest are the Goonyella Lower (6 to 8 m thick) and Goonyella Middle (6 to 10 m thick). This unit conformably overlies the marginal marine Exmoor Formation.

Geological Structure
The project area is located southwest of the Burton Range Fault Zone, a major northwest trending reverse fault. Thrust faults with a similar trend are indicated to be present in the broader area surrounding the project, and include the Suttor Creek Fault which passes through the project area. The main strike direction of the thrust faults is north-west. Evidence of smaller-scale faulting within the project area has also been identified during exploration works, in the form of seam repetitions and in- seam shear zones. The Permian formations in the project area strike north-north west, dipping to the east at between 4o and 12o .
