Project Scope

In the first newsletter for the 'Moolarben Coal Complex Open Cut Extension Project' published in June 2021, Moolarben advised it was investigating opportunities to extend open cut operations to the south of OC3 and east of OC4. Following further consideration, Moolarben has decided to focus on the OC3 extension area.

Potential extensions to OC4 are still being investigated and more information on that project will be shared in future newsletters and on this webpage.

Proposed OC3 Extension Project

The Project proposes to extend open cut operations to the south and east of its existing OC3 mining area. This will allow Moolarben to recover additional resources (approximately 40 million tonnes (Mt) of run-of-mine (ROM) coal) over a ten year period (from approximately 2025 to 2034). The Project would be integrated with the existing Moolarben Coal Complex and will not change the approved duration or intensity of mining at the Complex.

Current Status: EIS Public Exhibition

Moolarben has prepared an Environmental Impact Statement (EIS) for the OC3 Extension Project which comprehensively assesses the environmental, social and economic impacts of the Project in line the Secretary’s Environmental Assessment Requirements (SEARs) issued by the NSW Dept. of Planning and stakeholder feedback. The Project EIS was lodged with the NSW Dept. of Planning on 10 November 2022.

The NSW Dept. of Planning is now publicly exhibiting the EIS until 14 December 2022. You can view the EIS and make a submission using the following link Alternatively, you can also find the Project by searching for “Moolarben OC3 Extension Project” or “SSD-33083358” on the Planning Portal homepage.
