📐 Key Calculations
Decision Latency
Time from scan to boundary update
Result: 92 sec
Enables shift-level stope optimization
Dilution Avoidance
Dilution rate × waste density × volume
Result: −3.6 kt/stope
Direct recovery uplift
📊 Results
Dilution reduced from 14% to 5.8%, gold recovery increased by 9.3%, 22% reduction in development rework💡 Lessons Learned
