Deposit type is coal with thermal to semi-soft coking metallurgical properties (9.1)Geological setting is Bowen Basin, Rangel coal measures, coalescing of the Leichardt and Vermont seams (Average total thickness of 5.4m) Deposit strike is NNE-SSW (~5 deg) dipping at 5-5.5 deg bounded by regional.

Deposit dimensions are approximately 2.5km along strike and 1kn down dip. Deposit is constrained by a 120m depth cut-off limit, an average of 20m depth of weathering and fault structure/s in the North.

- Assumed mining method is conventional open cut strip mining, utilizing excavators, dozers and mining trucks similar to adjacent mine site/s
- 120m open cut depth limit has been assumed based on existing practicable open cut strip rations for similar marketable coal types in adjacent open cut mines
- No minimum mining thickness is assumed for the Mineral Resources, although no coal plies are less than 0.3m thick, which is commonly considered a thickness cut-off.

- Assumptions on the coal beneficiation process were based on the existing Millennium Coal CPP configurations
- Coal utilization and marketability is based of coal utilisation graphs using coal product results derived from detailed washability and product laboratory quality results
