Ep 124: Stochastic Mine Planning - Evolving approaches to manage uncertainty

Stochastic Mine Planning – Evolving the Way We Manage Uncertainty

In this episode, Tarrant Elkington (General Manager, Snowden Optiro) is joined by Matheus Faria (Director of Technical Services, KPI Mining) to explore the evolving role of stochastic mine planning.

Stochastic approaches move beyond conventional "single-input" mine plans by explicitly considering uncertainty in key parameters such as block models, recoveries, and prices. Tarrant and Matheus discuss how this approach can transform decision-making and create more resilient mine plans.

Key moments in the episode:

[00:02] – What stochastic mine planning is and why it's gaining traction.
[07:45] – Limitations of conventional deterministic planning.
[16:20] – Applying stochastic methods to sequencing, cut-off grades, stockpiling, and blending. [27:50] – Practical insights from Matheus on integrating stochastic planning into operations. [39:10] – Looking ahead: the future of stochastic planning in the mining industry.
[43:30] – Discussion on the real-world challenges of adoption, including computational demands and the need for organisational buy-in.
[50:05] – Reflections on how stochastic planning supports better communication between technical teams and decision-makers.
[55:40] – Final thoughts from both Tarrant and Matheus on where the industry is heading and advice for companies considering stochastic approaches. This episode offers valuable insights for mining professionals interested in risk management, decision-making, and the future of strategic mine planning.
