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

• Competent person (as defined in the SAMREC and JORC codes) at each operation who officially takes responsibility for estimating and reporting Coal Resources and/or Coal Reserves at operational or project level. These competent persons have been appointed and 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 persons' certificate.
• Technical specialists could include geologists, mining engineers, geohydrologists, geotechnical engineers, financial experts and economists, among others. Technical specialists who contributed to estimating the operation's Coal Resources and Coal Reserves are included in the original competent persons' report documentation with their contributions specified, as well as their names and signatures.
• Person(s) designated to take corporate responsibility for the Coal Resource and Coal Reserve estimates presented in the consolidated report are clearly differentiated from the competent person at an operational level who takes overall corporate responsibility.

Exxaro's Coal Resources and Coal Reserves have been estimated or supervised by the competent persons listed in Table 77 (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' report 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 (CMRR) report. Technical specialists who contributed to estimating the operation's Coal Resources and Coal Reserves are included in the original documentation where their contributions are specified, as well as their names and signatures.

The various appointed competent persons are either full-time employees at the operation (resident geologist or mineral resource manager) or, in the case of projects, the competent persons have conducted appropriate site visits to the mineral property being evaluated. All operations under Exxaro's control have been visited by the applicable competent persons.

Exxaro's lead competent persons are appointed by the management team. The Exxaro lead Coal Resource competent person is Henk Lingenfelder, a member of the Geological Society of South Africa and registered (400038/11) with the South African Council for Natural Scientific Professions. He has a BSc (Hons) in geology and 25 years of experience as a geologist in coal, iron ore and industrial minerals.

The Exxaro lead Coal Reserve competent person is Chris Ballot, a mining engineer registered (20060040) with the Engineering Council of South Africa. He has 24 years of experience in iron ore, mineral sands, and coal in various technical and management roles.
