GeoModeler is a geological and resource modeler:
- Drillhole Sub-module : Imports each drillhole as a separate object from CSV or Microsoft Access database format (*. mdb ). Imports a large number (>10000) of blast holes as a single drillhole collection object.
- Imports assays, attributes (categorical or continuous); Imports optional geological structures including faults as structural composites; Desurveys drillholes with choices of 5 Desurvey algorithms; Composites and color-codes drillholes by lithology, attributes or assays; Creates custom composite attributes as input to subsequent block model interpolations; Creates planned drillholes for drilling campaigns.
- Performs decile analysis on drillholes to determine assay caps.
- Option to filter or merge composites with a user defined formula.
- 3D Block Modeling with Sub-Blocking : Models vein or seam type deposits with non-axis aligned Mine North and non-axis aligned block models; M odel s large deposits with a huge block model universe (2^40 x 2^40 x 2^40); Models disseminated multi-orebody deposits with multiple block models in a single GeoModeler session; Creates block model masks for open-pit deposits; Creates and assigns user-defined attributes to block models with a visual formula/scripting editor; Manually assigns rock code to parts of a block model using a solid mesh; Includes integrated Block Model Reconciliation.
- 2D Gridded Seam Modeling (requires a GSM Modeler license): Creates Gridded Seam Models (GSMs) from drillholes; Resource estimation for GSMs; Performs Margin Ranking on GSMs; Converts GSMs to Block Models for Lerchs- Grossmann pit optimization for deeply inclined multi-seam GSMs.
- Implicit Modeling : Automatically creates rock type wireframes using Dynamic Anisotropic RBF; Creates grade shells using Dynamic Anisotropic RBF to evaluate what-if scenarios quickly .
Support for point, lines, surface, drillhole constraints and fault networks ; Supports faulted implicit wireframing ; Explicit editing of implicit grade or domain shells.
- Explicit Modeling : Manual Orebody Wireframing: Creates orebody outlines on parallel cross sections and then join them together to form orebody wireframes.
- Interpolates wireframes using Dynamic Anisotropic Inverse Distance Power, Kriging or SGS interpolation methods.
- 3D Variogram Modeling : Models anisotropy with 3D per-mesh variograms and non-axis aligned ellipsoidal search radii.
- Automatic batch mode experimental variogram generation using CPU or GPU to find the best variograms to use among thousands of possible choices.
- Option to auto-fit theoretical variograms to experimental variograms.
- Fault Network Modeling : Creates normal faults, reverse faults, strike-slip faults or combinations of the above fault types; Creates and manages fault networks with finite or infinite faults; Uses fault networks for unfaulted interpolation of faulted deposits.
- Constructs faulted orebody wireframes using fault networks and dynamic anisotropic RBF.
- Interpolation Submodule : Interpolates block model grades with high-performance Inverse Distance Power, Anisotropic RBF (Radial Basis Functions), Nearest Neighbor and multi-threaded Kriging methods (simple, ordinary, indicator and SGS, i.e., Sequential Gaussian Simulation) with or without geological domains and/or automatic normalization; Includes options to use unfaulting and dynamic anisotropy or unfolding for more accurate resource estimates.
- Options to perform stochastic orebody simulations using Multiple Indicator Kriging and SGS.
- Ability to recall interpolation settings for all interpolation runs.
- Data Analysis & Block Model Validations : Automatic assay capping using decile analysis; Creates distribution bar charts and curves for drillhole lengths, assays, composites and block models; Validates block models using Histogram Comparison Plot, Q-Q & P-P plots and Swath plots.
- Resource Classification and Resource Reporting : Classifies and exports estimated blocks into measured, indicated and inferred categories for public reporting;
- Advanced classification and custom report generation with ThreeDify’s formula-based Block Model Report Generator. Classification criteria include any combination of Kriging Variance, DNC (Distance to Nearest Composite), MDC (Mean Distance to Closest Composites), # of nearby samples and # of nearby drillholes, etc.
- DA or Unfolding Surface Creation : Creates Dynamic Anisotropy (DA) surfaces from composite points or orebody wireframe) for use in DA or Unfolded Interpolations.
- Topography/Geo-Surface Submodule : Creates gridded topographical or geological surfaces from drillhole collars, categorical attributes, structural composites, block models or an imported 2.5D mesh.
- GIS Integration : Plots drillholes and property lines on the Google or Bing map.
