Reserves & Resources

Porgera mineral reserves and mineral resources are reported on a 24.5% interest basis, reflecting Barrick’s expected ownership interest following the implementation of the binding February 3, 2022 Commencement Agreement. The Commencement Agreement provides, among other things, for ownership of Porgera to be held in a new joint venture owned 51% by Papua New Guinea (“PNG”) stakeholders and 49% by Barrick Niugini Limited (“BNL”) or an affiliate. BNL is jointly owned on a 50/50 basis by Barrick and Zijin Mining Group and will retain operatorship of the mine under the terms of the Commencement Agreement. Efforts are ongoing to execute the remaining definitive agreements to implement the Commencement Agreement and finalize a timeline for the reopening of the Porgera mine and resumption of full mine operations. For additional information, see page 48 of Barrick’s Fourth Quarter and Year End Report 2022.
