Exxaro Resources limited
Consolidated Mineral Resources and Mineral Reserves report 2021


The Exxaro annual estimation and reporting process is managed through Exxaro geosciences as well as LoM policies and associated Coal Resource and Coal Reserve reporting and estimation procedures. These policies and procedures are aligned with the guidelines of the JSE Listings Requirements (section 12:13) and the SAMREC Code 2016.

The policies and procedures dictate technical requirements for estimation and reporting, and include guidelines on methodologies, processes and deliverables. Procedures are also implemented for the geophysical, rock engineering, geotechnical, structural geology, hydrogeological, exploration and mine planning disciplines that prescribe methodologies and minimum standards for compliance.
