Antamina Mine
l Copper mine in Perul Key features include:
– Open Pit– Tailings Dam and Pond– Fresh water reservoir– Concentrator– Complex diversion system with multiple
routing options– Mine waters discharge to a river with
extensive human use (fishing, irrigation, etc.)

GoldSim Model Overview
l Contains component models for the following:– Water Balance Model
• Climate model– Historical precipitation record (for benchmarking)– Stochastic precipitation record– Custom User-Defined precipitation events
• Runoff and Surface Evaporation (expressed as monthly coefficients)
– Simple Mass Balance Model• Includes Cu, Zn, Pb, Mo, So4, NH4, NO3
• Comparison with various criteria at selected locations
– Tailings Production Model (based on ore campaign)

Next Steps
l Update mass loading model to reflect results of an ongoing geochemistry study
l Update model to reflect changes at the sitel Examine uncertainty in model parameters
(e.g., runoff coefficients) l Add submodel for the open pit and adjacent
basin
