摘要: In orebodies with very high-nugget gold it is not possible to reliably interpolate grades between drill holes. such cases geologists may resort using proxies for mineralisation help define the orebody. We present a method automating use of mineralised zones. Proxies be derived from categorical data logged by or continuous numerical values measured instruments, as multi-element geochemistry hyperspectral analysis. conditional probability finding high grade combine and evaluate proxies. The value can interpolated isosurfaced generate 3D model regions favourable mineralisation.
