In this episode of Fresh Thinking by @SnowdenOptiro , we explore recoverable resource methods and how they help bridge the gap between resource models and what is actually mined.

We discuss key approaches used across the industry, including Uniform Conditioning (UC) and Multiple Indicator Kriging (MIK), outlining how they address grade smoothing and improve predictions at the mining scale. We also cover the strengths and limitations of these methods, particularly their reliance on variograms and their inability to capture uncertainty.

This episode sets the stage for the next discussion on conditional simulation, where uncertainty and variability can be modeled more effectively.

Topics covered:

• What are recoverable resources?
• Why traditional estimation methods fall short
• Uniform Conditioning (UC) explained
• Multiple Indicator Kriging (MIK) explained
• Strengths and limitations of recoverable resource methods Subscribe for more insights on geostatistics, resource estimation, and mining best practices.

Episode 154 of Fresh Thinking by Snowden Optiro kicks off a 7-part series on modern resource estimation.

In this episode, we cover the fundamentals of ordinary kriging, its strengths and limitations, and introduce key concepts like grade smoothing, SMU, and recoverable resources.

Featuring Ian Glacken and Susan Havlin.

Discover the fascinating origins of Australia's nickel industry in this episode of Fresh Thinking by ‪@SnowdenOptiro‬.

Principal Consultant, Jan Graham, sits down with Executive Consultant, Ian Glacken, to explore the pivotal moment that sparked it all—the discovery of nickel at Kambalda in 1966. From early prospecting and geological insight to rapid development and industry-wide impact, this story highlights the role of luck, lateral thinking, and persistence in shaping one of Australia's most significant mining sectors.

Learn how a single drill hole, KD1, transformed Western Mining Corporation and led to decades of nickel production across Australia.
