Grade Control and Ore Reserve Estimation

Course objectives

• Apply sampling theory and identify the errors introduced before analysis
• Design grade control drilling and sampling for a deposit
• Operate quality assurance and control with standards, blanks and duplicates
• Apply variography and kriging alongside simpler estimation methods
• Classify resources and reserves against the reporting codes
• Define ore and waste boundaries for mining
• Reconcile the resource model, the grade control model and plant receipts
