Kimmer Estimation
Drillhole QA/QC and implicit geological modeling in one Windows desktop app. Kimmer Estimation imports your collar/survey/assay tables, validates them, then fits an anisotropic implicit model and builds grade shells and contact surfaces. It is in active private beta: the modeling engine is wired end-to-end, but this is a pre-release tool, not a reportable-resource package.
From raw drillholes to a labeled model shell.
Import and validate collar/survey/assay tables, desurvey and composite, then fit an implicit model and build watertight grade shells, with uncertainty, explainability, and clamped tonnage attached.
Import with column mapping
Read collar, survey and assay tables from CSV (delimiter auto-sniffed across comma/semicolon/tab, BOM-stripped) or XLSX/XLS/XLSM via an interactive column-mapping dialog with header-alias auto-detection. Multi-element assays import with per-element unit factors; re-import supports Replace / Append / Upsert with a pre-commit add-update-unchanged diff.
QA/QC catalog and dashboard
A validation catalog across Collar / Survey / AssayGeometry / Values categories with stable mnemonic codes and severity, live per-cell warning highlighting in the editable grid, and a control-sample dashboard: CRM charts at plus/minus 2/3 SD, blank contamination counts against k times detection limit, and duplicate precision pass-rate. Below-detection values follow half-detection / zero / keep-raw rules.
Desurvey and compositing
Minimum-curvature desurvey with a configurable dip-sign convention, then compositing to regular support in fixed-length or honor-lithology modes, length- and recovery-weighted, with source-interval tracking retained for traceability.
Implicit grade modeling
An anisotropic implicit engine that produces a grade estimate together with a per-location uncertainty estimate, plus a fast implicit engine tuned for closed grade shells at a chosen cutoff.
Grade shells and contact surfaces
Watertight grade-shell and contact surfaces. Multi-domain modeling fits per-lithology surfaces; vein modeling offsets thin tabular solids; a single planar fault acts as a hard barrier, modeled independently on each side with no cross-fault smearing.
Uncertainty, explainability, next drillhole
An uncertainty halo, an explainability probe reporting world XYZ, grade, uncertainty and which holes drive a region, a next-best-drillhole recommendation ranked by uncertainty times grade, an in-situ economic value skin with a price parameter, and a scenario diff that refits while dropping a fraction of holes to compare shell volume.
Tonnage estimate with a data clamp
Grade-shell volume times bulk density (constant or per-domain) gives an indicative tonnage. A distance-to-data clamp drops shell cells and triangles beyond a support radius to prevent phantom tonnage far from any drilling. Output is explicitly framed as an indicative model shell, not a reportable resource.
3D viewport and filtering
An orbit/zoom/pan 3D viewport with fit-view, click picking, and color-by-grade using Viridis / Turbo / Magma / Grayscale ramps. Ordered typed filter rules (hole id, lithology, grade element, elevation, recovery, interval length) combine with AND/OR to drive both the 3D view and the data sheet. Runtime English/Turkish switch, no restart.
An indicative model shell, honestly labeled
Kimmer Estimation is a beta implicit-modeling tool, not a resource-estimation suite. Estimation is implicit-modeling-based, not classical geostatistical estimation, and the output is deliberately labeled a model shell rather than a classified resource. Several planned pieces are on the roadmap, not shipping.
- No block-model / voxel grade estimation output
- No classical geostatistical grade estimation or variogram fitting
- No grade-tonnage curves and no JORC / NI 43-101 classification
- No mesh or surface export (OBJ/DXF/VTK/STL) and no CSV/PDF report export, only the .kestima project is saved
- Faster incremental model updates are on the roadmap; today every edit triggers a full rebuild
- Hardware-accelerated 3D rendering for larger scenes is planned
