Ep 128: Sampling mistakes that could cost millions
Small errors in sampling can lead to big consequences in mining.
In this second episode of our three-part series on sampling, Mark Murphy (Manager Geological Services, IGO) and Ian Glacken (Executive Consultant, Snowden Optiro) explore the different types of sampling errors - and how to recognise, minimise, and prevent them.
From unavoidable "correct" errors to preventable "incorrect" errors, they share real-world insights into why understanding sampling is critical for both technical teams and decision-makers.
Whether you're a geologist, mining engineer, or manager, this episode will make you rethink how you approach sampling in your operations.
