Fresh Thinking by Snowden Optiro

What makes a mineral critical? What makes it strategic? And why are governments around the world racing to secure supplies of certain commodities?
In this episode of Fresh Thinking by Snowden Optiro , Senzeni Mandava Matondi, Julian Aldridge, and Laurie Hassell explore the growing importance of critical and strategic minerals in today's economy. From copper, lithium and rare earth elements to gallium and germanium minerals, the discussion examines how countries define these resources and why those definitions matter.
The team explores:
The difference between critical and strategic minerals
Why supply risk matters
The role of minerals in national security and defence
Food security and fertiliser-related commodities
How critical mineral lists differ between countries
The influence of processing capability and intellectual property
The minerals driving the energy transition

Will AI replace geologists? In this episode of Fresh Thinking by  @SnowdenOptiro , we explore how artificial intelligence is being used across the mining industry, from exploration targeting and core logging to resource estimation and technical reporting.
Our team discusses the opportunities AI presents, its current limitations, and why geological expertise, judgement and accountability remain critical in mining workflows.

What are the key differences between private mining companies and publicly listed mining companies when it comes to project development, risk, and reporting? In this episode of ‪@SnowdenOptiro‬ 's Fresh Thinking podcast, Senior Consultant, Laurie Hassall speaks with Managing Consultant, Julian Aldridge, about how private companies approach mining project economics compared with companies reporting under the CRIRSCO framework. The discussion covers:
CRIRSCO Code compliance and disclosure requirements
Investor protection and technical defensibility
Resource and reserve classification
Mining project economics and financing strategies
Risk appetite in private vs public companies
ESG considerations in modern mining projects
How reporting standards influence mine development decisions
This episode provides valuable insight for mining professionals, investors, geologists, engineers, and anyone involved in mineral resource development and project evaluation.

In this episode of Fresh Thinking by Snowden Optiro, Ian Glacken and Susan Havlin explore localised conditional simulation (LCS) and its role in modern resource estimation workflows.
Building on earlier discussions around estimation methods, recoverable resources, and conditional simulation, this episode brings everything together to explain how LCS converts multiple simulation realisations into a single, practical block model—while preserving realistic grade variability. 
Key topics include: 
What localized conditional simulation is and why it matters
How localization transforms multiple realizations into a single model
The role of the E-type estimate in ranking and distribution
Differences between LCS and traditional ordinary kriging
How LCS supports recoverable resource estimation at the SMU scale
The origins of localization and its relationship to methods like uniform conditioning and MIK

In this episode of Fresh Thinking by ‪@SnowdenOptiro‬, Susan Havlin and Ian Glacken explore the fundamentals of conditional simulation and its role in modelling grade variability and uncertainty in mineral resource estimation.
They discuss how simulation differs from traditional methods like kriging and uniform conditioning, why capturing uncertainty is critical for modern mining decisions, and how multiple realizations can provide valuable insight into upside and downside risk.
 The conversation also touches on practical challenges, including reporting to the market and integrating uncertainty into mine planning workflows.
