Operation | Rehabilitation

Mining in Carnic and Orlea pits continues, while Cetate pit is reopened. The 4th pit, Jig, is also opened. Year 9 is the last year of mining in Carnic pit. The pit operations will take place alternatively, in order to optimize the closure plan and reduce the surface impacted by the mining activities.

Rehabilitation

Rehabilitation and re-vegetation are completed for the Orlea pit and the tailings dam. Rehabilitation and re-vegetation of the depleted ore stockpile begins, while flooding of the Cetate pit continues. The land related to Jig pit, which has been rehabilitated, re-enters the agricultural circuit this year.

Rehabilitation

Rehabilitation of the tailings dam continues, as well as water treatment in the Cetate pit, until it complies with the quality requirements for surface waters. The tailings management facility re-enters the agricultural circuit. Starting with year 25, for a period estimated at between 30 and 50 years, post-closure monitoring continues.

Note: This planning is only indicative, as the actual duration and sequence of events will be further improved and detailed during the operation phase, being completed before the implementation of the closure program. All the rehabilitation activities included in this plan are to be carried out by RMGC.
