564 ultimately concentrated in the feeding, pumping, and screening infrastructure that defines the sustainable capacity limit. Figure 3. Simulation Block Flow Diagram illustrating the interaction between process areas and buffer nodes (B.01-B.09) within the roadmap. 4.5 Quick Wins Phase: Stabilizing the Revised Operating Baseline The Quick Wins phase focused on stabilizing the revised operating baseline with minimal capital intervention. The model identified two practical actions: VFD tuning of the concentrate conveyor (TR-2030) and improved control of cyclone feed sump variability. These measures reduce local instability and support short-term throughput improvement, but they are insufficient to overcome the structural bottlenecks that define the sustainable capacity limit of the plant. 4.6 Optimal Point Selection (Sweet Spot) To determine the effective investment limit, the Unitary Value at Cost (VAC) was used as the deciding metric. The analysis revealed three critical economic zones: • Efficiency Zone (Alt. 1-4): The unitary VAC remains competitive, ranging between 0.87 and 1.07 USD/t. • The Optimal Alternative (Alt. 4): This configuration reaches 4.96 Mtpa (2,718 t/h of wet feed) by synchronizing capacity across the feeding conveyors, primary cyclone feed pumps, and screening circuits, while maintaining an Overall Equipment Effectiveness (OEE) above 88%. • Saturation Zone (Alt. 5+): Attempting to exceed 5.0 Mtpa causes the unitary VAC to jump to ~1.8 USD/t, as the required expansion moves beyond coordinated debottlenecking and into major
