Final Recommendation
Based on the metallurgical, economic, and environmental evidence presented across this report, the **Flotation + Concentrate Leach** route is the superior processing option for a 3.0 g/t historical tailings resource.
Direct CIP is structurally disadvantaged due to:
• Preg-robbing losses
• High cyanide and lime consumption
• Large tankage requirements
• High detoxification costs
• Elevated environmental liabilities
Flotation, by contrast, isolates the gold-bearing sulfides into a small mass fraction, enabling:
• Higher recoveries (80–85%+)
• Lower reagent consumption
• Lower capital intensity
• Lower environmental footprint
• Better long-term ESG positioning
For investors, this translates into:
• Higher NPV
• Lower risk
• Faster payback
• Greater operational resilience
**DMMP’s recommendation is clear:** A flotation-based flowsheet should be the foundation of any feasibility study for this resource.
