Fresh Thinking by Snowden Optiro

In this episode of Fresh Thinking by Snowden Optiro, Tarrant Elkington (General Manager, Snowden Optiro) is joined by Joseph A. Dos Santos (Joe) (Dos Santos International, Marietta, Georgia) to explore high-angle conveying and the sandwich conveyor. They break down how sandwich conveyors "hug" the material between two belts to move bulk solids up steep inclines, where conventional conveying or trucking can become impractical. The discussion covers how this technology is applied in mining, what it can handle, and what to consider when comparing high-angle conveying against other haulage and lifting options. Key moments 00:01:05 – What is a sandwich conveyor? 00:02:27 – How sandwich conveyors handle extreme angles (including the "hugging" mechanism). 00:09:09 – Where high-angle conveying fits compared with truck haulage and other systems. 00:21:17 – Real-world scale example: vertical lift, capacity, and what that looks like in practice. 00:40:24 – "Mining on Mars" and why high-angle conveying comes up in off-world concepts.

Mineable Shape Optimisation (MSO) sits at the intersection of geology, mining engineering, and economics. Used well, it helps teams move beyond theoretical resources and towards designs that reflect what will actually be mined. In this episode of Fresh Thinking, Dr Gregory Zhang (Senior Resource Geologist) and Hamish Guthrie (Managing Consultant - Mining) discuss how MSO works, why it matters, and where it can add real value. They discuss the economic logic behind MSO, the importance of geological understanding, and how assumptions around cost, dilution, and mining method influence the outcomes. Key moments 00:02 – What MSO is and why it's used in underground mining 01:53 – The economic logic behind MSO and cut-off decisions 02:48 – Geological inputs that matter most for MSO outcomes 04:49 – How MSO actually works under the hood 06:13 – Comparing underground MSO with open pit optimisation 08:09 – Using MSO to manage dilution in narrow vein deposits 10:30 – Sensitivities, parameters, and study-level considerations 11:17 – Common pitfalls and how to avoid them 14:49 – A practical MSO workflow: inputs, outputs, and communication If you enjoyed this episode, please Subscribe for more mining-focused technical discussions across the mine value chain.

In this episode of Fresh Thinking by Snowden Optiro, Tarrant Elkington (General Manager, Snowden Optiro) is joined by Markus Dammers (Director, IPCC & Conveyors, Metso) to talk about what IPCC really means in practice, and whether "strategic conveying" is a more useful way to frame the conversation. They explore the spectrum of IPCC options (fixed, semi-mobile and fully mobile), where value is actually created (and lost) in mine planning, what people often miss when they consider in-pit systems, and how lead times, standardisation and decarbonisation assumptions influence decisions. Key timestamps: 1:24 What does "IPCC" actually cover (and why it's often used as an umbrella term)? 3:37 IPCC's real purpose: reducing trucks, not always eliminating them 5:39 Is "strategic conveying" a better term than IPCC? 7:25 Fully mobile (truckless) IPCC: where it works, and why hard rock is challenging 12:30 In-pit crushers: the planning and operational complications people underestimate 18:53 Lead times, standardisation and improving study-to-delivery pathways 24:41 Decarbonisation: diesel, carbon assumptions, and balancing ESG with economics 29:57 Wrap-up and how to learn more If you enjoyed this episode, please subscribe for more mining-focused technical discussions across the mine value chain.
