The Pre-Feasibility Study (PFS) for the North Surat Project consisting of Elimatta, Taroom, Collingwood and Woori was completed during the 2020 financial year. On ground exploration and coal quality and washability program at Taroom was completed, new geological models were developed internally for both the Taroom and Woori projects. |

Summary:
Taroom
The Taroom project is located 9km south-southeast of the township of Taroom and approximately 450km by road north-west of Brisbane. The topography shows minor relief across the project area with intersections from the Juandah Creek tributaries. The coal measures gently dip to the south-west.
Located within the northern Surat Basin on the eastern flank of the Mimosa Syncline, coal within the Taroom project is contained within the Taroom Coal Measures from the Walloon subgroup. The Taroom Coal Measures are overlain by the Tangalooma Sandstone. These coal measures have been re-correlated to regional naming convention to the Auburn, Bulwer and Condamine seam sequences.
The coal seams intersected at Taroom are characterised as multiple thin plies, which coalesce in their respective parent seam units. With the marine sedimentary influx into the depositional system, some reworking and lensing of minor plies are evident. Core interburden analysis plays a key role in depositional environment definition. Sixty individual coal plies have been correlated and modelled as elements (daughters), with five compounds (parents). The individual seams have been assigned to seven seam groups. In decreasing stratigraphic order, the seam groups are the A (Auburn), B (Bulwer) and C (Condamine) seams.
Coal quality laboratory results are consistent with a thermal coal product suitable for both export and domestic markets.

Summary:
After a comparative evaluation of several mining alternatives, a preferred mine plan incorporates the following features:
- Use of conventional strike line stripping operation with nominal 60m strip widths
- Use of large carry dozers
- Relocation of Back creek to the north-east in the early years of mine operation
- Relocation of the Leichardt Highway to the east of the tenement.
The Taroom Project is planned to be mined using an open cut mining method. The open cut mining method will be a combination of truck and excavator stripping and bulk dozer push of waste overburden and interburden. As the coal seams in the Taroom deposit are relatively thin, a coal mining method of dozer assist rip and stack will be utilised to rip and push up the coal to be mined into stockpiles on the mining bench. Front end loaders will then mine and load the coal into haul trucks to haul the coal to the Coal Handling and Preparation Plant for processing. Some thin interburden split out from the coal working sections will be handled the same way as the coal utilising the dozer assist rip and stack method.
A conservative 45-degree overall batter angle has been utilised as the geotechnical highwall and end wall batter angle for the Taroom project.
The Woori Project may be amenable to an open-cut, thin seam mining operation within the Surat Basin.
