Exxaro applies three levels of ‘competency’ to estimating mineral resources and ore reserves:
- Competent person (as defined in the SAMREC and JORC codes) at each operation who officially takes responsibility for estimating and reporting mineral resources and/or ore reserves at operational or project level. These competent persons have been appointed and acknowledged their acceptance of accountabilities. Their names, qualifications, affiliations and relevant experience are included in the independent operational and project reports in the format of a competent person certificate.
- Technical specialists who contribute in any way to estimating mineral resources and/or ore reserves and are named on each operation’s mineral resource and ore reserve statement. Technical specialists could include geologists, mining engineers, geohydrologists, geotechnical engineers, financial experts, economists, etc. Technical specialists who contributed to estimating the operation’s mineral resources and ore reserves are included in the original CPR documentation, where their contributions are specified and their names and signatures appear.
- Person/s designated to take corporate responsibility for the mineral resource and ore reserve estimates presented in the consolidated report. This definition clearly differentiates the competent person on an operational level from the person(s) who takes overall corporate responsibility for the mineral resource and ore reserve estimates presented in this report.
Exxaro’s mineral resources and ore reserves have been estimated or supervised by the competent persons listed in table 22 on an operational basis in accordance with the SAMREC 2016 for South African properties and the JORC Code 2012 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 they have taken responsibility for, 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 the original mineral resource and reserve statements 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 resource and reserve report. Technical specialists who contributed to estimating the operation’s mineral resources and ore reserves are included in the original documentation, where their contributions are specified and their names and signatures appear.
The various appointed competent persons are either full-time employees at the operation they are reporting on (i.e. resident geologist, mineral resource manager) or, in the case of projects, the competent persons have conducted applicable site visits to the mineral property being evaluated. All operations under Exxaro’s control have been visited by the applicable competent persons.
Exxaro lead competent persons are appointed by the Exxaro management team. The Exxaro lead mineral resource competent person is Henk Lingenfelder, a member of the Geological Society of South Africa (GSSA) and registered (400038/11) with the South African Council for Natural Scientific Professions.

The Exxaro lead mineral reserve competent person is Chris Ballot, a mining engineer registered (20060040) with the Engineering Council of South Africa. He has 21 years of experience in iron ore, mineral sands and coal in various technical and management roles.
