Why Bad Data Breaks Predictive Models: Microscale Textures, Hyperspectral Unmixing, and Mine Profitability

Man analyzing 3D geological model on screen.

Predictive models now drive high stakes decisions throughout the mining industry. The promise is clear: Enhanced targeting, improved resource estimates and more consistent mine profitability. Yet, many sites find that their models fail after real world deployment. Discrepancies appear between predicted grades and actual results, unexpected processing challenges surface and anticipated profits slip away. Modern…
