‚ÄčRavensworth Surface Operations (RSO) comprises of two open cut mines; Narama and Ravensworth North mines. RSO also manages Cumnock Mine, a former open cut and underground mine, now under care and maintenance.

Narama Mine commenced in 1993 as a continuation of an ongoing thermal coal supply contract to Macquarie Generation (previously known as the Electricity Commission of NSW) since 1972. As an extension of the domestic coal supply, Ravensworth West Mine commenced thermal coal production in parallel with the Narama Mine in early April 2006. Mining in Ravensworth West ceased in 2011.

Ravensworth Surface Operations submitted a development application for the Ravensworth Operations Project in February 2010. This application was approved by the Department of Planning and Infrastructure (DP&I) in February 2011 (PA 09_0176).  The Prjoect Approval comprises of the development of the Ravensworth North mine at Ravensworth Surface Operations and the consolidation of existing approvals for open cut mining and infrastructure, including the Ravensworth Central Coal Processing (RCCP) facility, within the Ravensworth Area. The single project approval has provided for the integration of operational aspects of the mining operations, allowing for a consistent and integrated approach to environmental management and mine planning. Mining in Ravensworth North commenced in April 2012, with first coal extracted in May 2012..

RSO can now produce up to 16 Mt of Run of Mine (ROM) coal per year. Coal currently produced at Ravensworth Surface Operations is utilised for both the domestic and export market.
