How we report

Competent Persons

Exxaro applies three levels of "competency" to estimating Coal Resources and Coal Reserves:

  • Competent Person (as defined in the SAMREC and JORC codes) who officially takes responsibility for estimating and reporting Coal Resources and/or Coal Reserves at operational or project level. These appointed Competent Persons have acknowledged acceptance of accountabilities. Names, qualifications, affiliations and relevant experience are included in the independent operational and project reports in the form of a Competent Person's certificate
  • Technical specialists, including geologists, mining engineers, geohydrologists, geotechnical engineers, financial experts and economists, among others. The Competent Persons' report or Resource and Reserve report contains the names, signatures and contributions of technical specialists who contributed to estimating the operations' Coal Resources and Coal Reserves
  • Persons designated to take corporate responsibility for the Coal Resource and Coal Reserve estimates presented in the consolidated report are differentiated from the Competent Person at an operational level, who takes overall corporate responsibility.

Exxaro's Coal Resources and Coal Reserves were estimated or supervised by the Competent Persons listed in Table 2 (name, affiliation and relevant experience) on an operational basis in accordance with the SAMREC Code for South African properties and the JORC Code for Australian properties. All Competent Persons have sufficient relevant experience in the style of mineralisation, type of deposit and/or mining method(s) under consideration and/or being mined, and for the activity under their responsibility to qualify as Competent Persons, as defined in the applicable codes at the time of reporting.

The appointed Competent Persons have signed off their respective estimates in their original Competent Persons' reports for the various operations, and consent to the inclusion of the information in this report in the form and context in which it appears in the Consolidated Mineral Resources and Mineral Reserves report. The appointed Competent Persons are employed full time at the operation as the resident geologist or mineral resources manager. In the case of projects, the Competent Persons conducted appropriate site visits to the mineral property being evaluated. All operations under Exxaro's control were visited by the relevant Competent Persons.

Exxaro's lead Competent Persons are appointed by the management team.
