GOVERNANCE AND INTERNAL CONTROLS Mineral Resources and Ore Reserves are estimated either by suitably qualified consultants or internal personnel in accordance with the applicable JORC Code and using industry standard techniques and internal guidelines for the estimation and reporting of Mineral Resources and Ore Reserves. All data is collected in accordance with applicable JORC Code requirements. Ore Reserve estimates are based on pre-feasibility or feasibility studies which consider all material factors. The estimates and supporting data and documentation are reviewed by qualified Competent Persons (including estimation methodology, sampling, analytical and test data).
