EP 135: Fast-Tracking IPCC Feasibility: A Smarter Way to Evaluate In-Pit Crushing and Conveying

In this episode of Fresh Thinking by Snowden Optiro, Dr Tarrant Elkington (General Manager, Snowden Optiro) and Markus Dammers (Director IPCC & Conveyors, Metso) explore their rapid screening tool designed to speed up evaluation of In-Pit Crushing and Conveying (IPCC) options.  They discuss how the model helps mining operations quickly assess economic viability, reduce decision uncertainty, and identify where IPCC truly makes sense - saving valuable study time and capital. If you're in mine planning, haulage optimisation, or exploring electrification and sustainability in mining, this episode is packed with insight. Key Points & Timeline 1:00 – Why the Paper and Model Were Developed The challenge of evaluating IPCC options and the need for a quick, macro-economic decision framework. 3:30 – Complexity of IPCC Decisions Discussing parameters such as pit depth, relocation timing, and haulage versus conveying trade-offs. 4:00 – Origins of the Rapid Screening Tool How a practical spreadsheet model evolved to assess the feasibility of IPCC across multiple projects. 6:00 – Key Inputs and Parameters Understanding capacity, conveyor length and lift, and the dynamic relationship between truck and conveyor economics. 8:00 – Macro-Economic Viewpoint Why early-stage, big-picture modelling matters for major mine investment decisions. 9:00 – How the Model Works Overview of how the Excel-based tool compares IPCC and trucking using NPV, IRR, and payback calculations. 11:00 – Ore vs Waste Applications How the economics differ when applying IPCC to ore versus waste haulage scenarios. 12:00 – Building Reliable Cost Models Markus explains Metso's structured approach to estimating realistic capital and operating costs for crushers and conveyors. 15:00 – Accounting for Excavation and Ramp Design Tarrant explains the importance of considering excavation and pit geometry in cost evaluation. 17:00 – Case Study Results Findings from applying the tool to typical mining scenarios, comparing ex-pit and in-pit setups. 19:00 – Economic Sensitivities and Insights Discussion of throughput, lift, and distance variables — and how they shape viability. 21:00 – Waste IPCC Economics Why higher capacities and longer distances are needed to make waste IPCC feasible. 23:00 – Future Improvements and Next Steps Potential refinements to the tool and how it could support more dynamic project planning. 2 4:30 – Closing Thoughts How to access or apply the model for your own operation and where to contact the speakers.
