resource classification

Why your mine plan’s lying to you - and what Rondon and Assibey-Bonsu say to do about it before it costs you millions in misclassified waste and phantom tonnes

At the AusIMM 2025 Mineral Resource Estimation Conference, Dr Oscar Rondon, principal geostatistician at Datamine, tackled a question that has dogged mining professionals for decades: Is estimating recoverable resources still hopeless? The talk revisited a decades-old challenge in resource estimation, combining Rondon’s clear communication with Assibey-Bonsu’s extensive experience in the mining industry.

Kriging is cheating, the best estimate is a myth, and it's time resource modellers embraced uncertainty to do it right—and ethically

In a rousing keynote at AusIMM’s 2025 Mineral Resource Estimation Conference, Dr Clayton Deutsch—director and professor at the School of Mining Engineering, University of Alberta—challenged the audience to confront a fundamental flaw in how mineral resource estimators approach their craft.
