The term "critical metal" typically brings to mind elements like lithium, used in batteries, or rare earths, vital for high-tech applications. However, the essence of a "critical" substance is its foundational role in an economy, and by that measure, iron ore is indeed critical. Its importance is entrenched in every steel beam, car, bridge, and countless other products and structures.

In narrow orebodies the use of ordinary kriging (OK) may pose certain limitations when used for grade control modelling. The smoothing effect of kriging, by its very nature, cannot retain or accurately characterise the dispersion (variability) that is inherent in gold deposits. This dispersion is a critical component of determining the desired level of ore loss and dilution.Fixed block …
