Item Description
Information Requested
1
Off lease disturbance
Provide advice on this off-lease discrepancy identified and detail how this will be rectified via this amendment.
The proposed revision of figure 1 (Mine Area Location) of environmental authority (EA) EPML00433013 is depicted in figure 9 of the application material (Wulguru, 2025) 1 . It appears disturbance footprints extend outside of tenure boundaries. Specifically, the Red Oxide Tails, Q Dump and a section of haul road northeast of the mining/contractor yard. Mining related disturbance subject of the EA is not authorised outside of tenure boundaries.
Clarify if there is an intention to include a mine equipment park up and workshop area to the EA. If so, provide all necessary information for its inclusion. For example, description of the infrastructure, location, footprint size, identification of environmental values and the associated risks, impacts and management measures, and rehabilitation information for this feature.
2
Regional interest development approval
It is identified that regional interest development approval RPI17/001 is approved for the project. Upon review of the documents publicly available related to RPI17/001, it is acknowledged that a ‘mine equipment park up and workshop’ is proposed downstream of the proposed Upper Mundic Gully Tailings Storage Facility (UGM TSF), however, this is not reflected in this application.
3
Ancillary infrastructure
Provide revised application material which describes all ancillary infrastructure required for the construction and operation of the UGM TSF. If ancillary infrastructure is proposed provide: a) A description of each feature proposed including an assessment against the environmental values, impacts and risks to environmental values and the management and monitoring measures, and rehabilitation information. b) A description of the location, including maps, GPS co-ordinates and total disturbance area in hectares (ha) for each feature. Information
Limited information is presented regarding if ancillary infrastructure is required to support the construction and operation of the UGM TSF. For example, this may include laydown areas potentially for pump systems, haul roads, access tracks, tailings pipeline and topsoil stockpiles. Further, as indicated in information request item 2 , this may also involve a mine equipment park up and workshop area.
