Resource audits

Mining professionals have to plan very carefully, for future resource and reserve audits, right from the commencement of exploration. Resource audits are similar to financial audits. They follow a sequence of paperwork set out in a logical path, to validate that best practice has been followed from geological sample to the database and into the mineral resource model. A sample audit trail, as an example, will establish that a specific set of assay results used for a mineral resource or a production efficiency calculation can be traced back to a specific sampler, a specific sample and a specific analysis.
