In mining, success depends not just on what we extract but on how well we do that. And to optimize the mining process, we need to understand the orebody. A.k.a Orebody knowledge. Orebody knowledge is not just a buzzword. It encompasses a wide range of fields (geological, geotechnical, geochemical, and metallurgical) that described the characteristics of a deposit. It’s the backbone of informed decision making across the mine life cycle. Exploration to closure. ✅ Why it matters: - Accurate resource estimation - Safer and more efficient mine designs - Optimized extraction and scheduling - Reduced operational risk - Improved processing and recovery - Safer waste rock and tailings disposal Geotechnical characterization and domaining is just one part aspect of "Orebody Knowledge" but it is a key contributor to optimize the mine design/extraction sequence and execute it safely. The image (Sala & Santos 2022, modified from Read & Stacey, 2009) below is a great illustration of the typical inputs to a geotechnical domain model. Deposits and mining methods differ, and the geotechnical characterization is adjusted accordingly. As it should be. But here’s the question I’d love to hear your thoughts on: Which aspect of geotechnical characterization and orebody knowledge do you think is most overlooked? As an example: microdefects/veining is not explicitly shown in the figure while it has a material impact on porphyry deposits. Which aspects should we pay more attention too?
