From logged contacts to geometry

Turn a geologist's reading into a model you can measure

Desurvey logged drillholes, model contacts implicitly as a scalar field, and contour that field into watertight geological and grade shells — reviewed in one 3D scene alongside the holes they came from.

GeoMine Studio 3D view of an interpolated ground surface above drillholes and a vein shell. — The ground surface interpolated from 113 collar elevations, with the drillholes and vein shell beneath it.

Target audience

Exploration and resource geologists, geological modellers, mine geology teams, and technical services groups.

Platform capabilities

Drillhole desurveying from collars, surveys, and logged intervals

Contact extraction with the dropped-station accounting shown, not buried

Implicit scalar-field modelling of a declared stratigraphic column

Isosurface extraction with recorded volume, area, and Euler characteristic

Nested shells rendered as layers of one model, ordered by isovalue

3D review with sections, vertical exaggeration, measurement, and A/B comparison

Open surfaces declared as open rather than reported with a meaningless volume

Business benefits

Make a geological interpretation geometric and reproducible

Keep the holes visible beside the model they produced

Give downstream estimation a boundary it can be constrained by

Record whose interpretation it is, on the artifact itself

Implicit Geological Modelling in the product

The screens that support this workflow, shown in the working application.

GeoMine Studio 3D view of the Groundrush drillholes with the vein shell. — Groundrush, a public open-file gold project: 113 drillholes in 3D around the vein shell solved from their logged contacts.

GeoMine Studio 3D block model coloured by gold grade beneath the ground surface. — Ordinary kriging on a 20 × 20 × 10 m lattice inside the vein shell, coloured by grade (g/t Au).

DataHub import job with validated staged rows ready to commit. — Collars staged and validated row by row — nothing touches the domain until the file is committed.

GeoMine Studio 3D view of drillholes, a ground surface and kriged blocks on a dark background. — Groundrush, a public NTGS open-file gold project: drillholes, the interpolated ground surface and an ordinary-kriged block model in the vein shell.
