The mining engineering design team will design and evaluate the economics of a leach pad expansion. The design will include location selection for the leach pad and collection pond, liner design, and the sequence and stacking for the pad. The design will include a stability assessment and incorporate environmental and permitting considerations. The metal recovery design will include a process flow sheet, tons, mass balance, time rate, and recovery estimates. A trade-off study for trace mineral recovery, including Au, Ag, and Mo, should be completed.
