1.2.4 Catalogue of potential resource developments


Summary

There are currently 20 thermal coal deposits defined in the geological Galilee subregion with a combined identified resource tonnage (based on publicly released coal resource data) totalling about 36 billion tonnes. Most of these resources are hosted in Permian rocks that are close to surface along the eastern basin margin, extending in an arcuate zone from the central to the northern part of the subregion (Figure 12 in Section 1.2.3). However, there are also several identified coal resources south of Blackall which are hosted in Cretaceous rocks of the Eromanga Basin, younger than most other coal resources in the Galilee subregion.

There are three coal seam gas (CSG) prospects in the basin for which contingent resources (2C and 3C) have been defined. The coal and CSG projects listed in this catalogue are considered to be those which could potentially be developed into commercially producing mines or production fields at some time in the future, for example, within the next 10 to 20 years. Further analysis of each resource project listed in this catalogue will be used to determine the most likely coal resource development pathway in the Galilee subregion. The coal resource development pathway will then be reported in the product 2.3 for the Galilee subregion (conceptual modelling).

Potential coal resource developments in the Galilee subregion are listed alphabetically in Table 13 and shown in Figure 12 of Section 1.2.3. Most of these 20 coal deposits have an identified coal resource, as defined using the terminology of the Australian national classification system for mineral resources. This means that, as a minimum requirement, there is at least an inferred resource publically available, as reported in accordance with the JORC Code (refer to Appendix 1 in GA and BREE (2013) for further information on the resource classification schemes mentioned here). In some cases, the more advanced development projects also have measured and/or indicated resource estimates, indicating that there is an increased level of geological understanding about these resources.

The deposits listed in Table 13 are considered to be those within the Galilee subregion that could potentially be developed into commercially operating mines at some stage in the future. Two of the deposits mentioned previously in this report – Carmichael East and Degulla – are included in this catalogue even though it is currently unclear if a coal resource (as reported in accordance with the JORC Code) has been estimated. An assessment of the likelihood for each of the listed resource projects to be developed into a mining operation will be undertaken during the model-data analysis stage of the Galilee bioregional assessment (component 2). This analysis work will help to determine the coal resource development pathway in the subregion, which will be reported in product 2.3 for the Galilee subregion.

The potential coal seam gas (CSG) resource developments in the Galilee subregion are listed in Table 14. These three CSG plays all have current estimates for contingent resources (2C and 3C). Thus, there are currently no CSG commercial reserves (proved, probable or possible) identified within the subregion. Similar to the coal resources, further analysis of these CSG plays in the Galilee Basin will be undertaken to determine the CSG projects to be included in the Galilee coal resource development pathway.
