Exploration and mining companies require their resources to be defined based on strong data integrity, estimated using the most appropriate technical techniques and adhering to relevant guidelines (JORC 2012, SAMREC, NI43-101). Recent developments in estimation methods are being used to better define grade distribution at the local (SMU) scale, often with substantial positive financial impacts.
