Core is the ‘engine’ of Micromine and is always included in every installation. This essential component allows you to import, validate, process, display and interpret a wide variety of surface, drillhole and subsurface data.

Key Features

  • 32-bit and 64-bit architecture
  • Fast and flexible data import, export, entry, editing, processing and validation
  • Direct import and export of Excel workbooks
  • External database linking using ODBC
  • A flexible file format that can contain any combination of text and binary data
  • On-the-fly data filtering, with optional hiding of excluded records
  • Dynamic field expressions for using on-the-fly calculations as inputs to other processes, including a dedicated calculator for arithmetic operations
  • Ability to save the settings on any dialog as a ‘form set’ and instantly recall them for later use
  • Central form set management tools with natural search, locking (make read-only), drag-and-drop movement and copying, and import and export options
  • Creation, validation and management of drillhole and trench databases
  • Coordinate conversion between most common coordinate systems used around the world, including local plane grids
  • Basic gridding and contouring functions
  • A built-in calculator for essential mathematical calculations
  • Statistical summary, charts and reports for basic exploration data analysis, including interactive statistical decomposition on a histogram or probability plot
  • Survey functions for basic exploration field collection
  • Simple grade-tonnage calculations using polygonal outlines
  • Customisable keyboard shortcuts
  • Easy-to-use macros for automating or repeating any Micromine process
  • The Python programming language for more advanced automation or repetition
  • An easy-to-use built-in support request form

Key Benefits

  • Dual architecture (32-bit and 64-bit). We recommend installing both versions your PC and using:
    • 64-bit Micromine to access all available system memory
    • 32-bit Micromine to avoid driver problems that affect all 64-bit applications
  • The tools  to visualise, interpret, design, present, and communicate your project data within Vizex
  • Drillhole functionality for essential exploration data collection and interpretation
  • Compatibility with all currently supported file types including mining, CAD, GIS and image processing applications; ability to export to some of those same types (see Core COMPATIBILITY). These supported file types make it easy to incorporate Micromine in a multi-application workplace
  • Spatial editing tools for essential geological interpretation and basic engineering design tasks
  • A flexible file format that allows you to store numerical information as either binary or text, providing total control over your data:
    • Numbers stored as text may still be used in calculations. Non-numeric codes (“LNR”) and alphanumeric values such as above (“> 1000”) or below detection (“< 0.01”) are treated as valid entries, maintaining compatibility with typical laboratory assay reports
    • Numbers stored as binary data offer advantages in speed, size and accuracy, but cannot handle nonnumeric codes
  • Support for creating basic ‘quick grids’ to model geochemical data
  • Statistical charts and reports for basic exploration data analysis (including statistical decomposition) without requiring additional software

Refer to the system requirements for recommended hardware and operating system specifications.

Vizex Visualisation Environment provides

As a Core user, you view supported data using Vizex (Visual Explorer), a visualisation environment for displaying, querying and interactively editing multiple data layers.


  • Multiple-document, multiple-window interface for displaying any number of graphical or tabular windows, which can be docked, tabbed, or tiled
  • A viewing environment that displays virtually all Micromine-supported data (some advanced types need additional modules)
  • Drag-and-drop supported file types directly into Vizex
  • Inbuilt Project Explorer provides direct access to all project files within Micromine
  • Session management options for saving and reloading a full Micromine session, including all windows and, optionally, data
  • Ability to export 3D views to CAD or virtual reality file formats


  • Highlighting of clipped section limits as ‘corridors’ in other views
  • Seamless 2D/3D transitions with direct access to user-defined views in any orientation
  • Flexible view management tools including user-defined Section Control Files, interactive section browsing tools, single section planes, and zoom-to-selection capabilities
  • Real-time stereoscopic 3D viewing
  • Lighting and background options, including sky/ground colours for semi-realistic displays
  • Intuitive and interactive tools for creating and exporting fly-through animations


  • Numerous 2D and 3D coordinate grid and axis overlay options, including superimposed secondary grids
  • A floating scale-bar within the Vizex window
  • Annotation tools for creating labels, callouts and arrows


  • Comprehensive per-object configuration tools including labelling, symbolisation, draw style, visibility, dynamic data pop-up, snapping and selection
  • Advanced display options like transparency (for images, wireframes and block models), image draping, interactive block model visibility (using a slider to show or hide blocks based on a numerical value), and maximum intensity projection (for point clouds)
  • Colour, hatch (pattern), symbol and line set (symbology) editors with virtually unlimited numbers of entries
  • Pre-defined palettes and colour tables, including the ColorBrewer collection and 256-colour palettes for continuous phenomena like topographic elevation
  • Scalable fonts and markers that can be set in points or real-world units


  • Streamlined and intuitive spatial editing with the Active Layer. Simply click a feature in any editable layer to start modifying it
  • Smart snapping tools including snapping to points, lines, perpendicular to lines, surfaces, coordinate grids and intersections. You can also snap when you’re not editing, for example while measuring length or area, or drawing interactive sections
  • Many editing and manipulation tools including curves, gradients, bearing/distance, splitting, between-point, simplification, replication, mirroring and more
  • Spatial operations including draping and smoothing strings, area calculations, and point-in-polygon assignment
