Deep-dives on estimation, modelling, pit optimisation and reporting — written by the practising geologists and engineers who ship SMIN.
A pragmatic tour of Ordinary Kriging — variograms, weights, negative kriging, and why it's still the workhorse estimator in 2026. No sigma notation, no proofs, just the intuition every practising geologist should have.
Picking the wrong iso-value collapses your ore shell into either an implausible blob or a shattered sliver. Here's the field-statistics approach we use inside SMIN to keep grade shells honest.
From ignoring rock-domain slope zones to over-fitting revenue factors, the five sins we see most often on customer LG runs — and the fixes that unlock a defensible optimal pit.
Same estimate, two very different disclosure regimes. What every geologist needs to know when the same block model has to satisfy both an ASX-listed junior and a TSX-listed producer.
InstancedMesh, frustum culling, custom shaders and a handful of hard-won GPU-profiling lessons. A tour of SMIN's 3D viewer architecture for readers who care about frames per second.
Distance-to-composite is the industry default, but slope-of-regression is a materially better proxy for local kriging variance. Our real-world data on why we made the switch.
