Exxaro applies three levels of "competency" to estimating Coal Resources and Coal Reserves:
Exxaro's Coal Resources and Coal Reserves have been estimated or supervised by the competent persons listed in Table 82 (name, affiliation and relevant experience) on an operational basis in accordance with the SAMREC Code 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 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 the original Mineral Resource and Mineral 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 Mineral Reserve report. Technical specialists who contributed to estimating the operation's Mineral Resources and Mineral 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.
