Resource Estimation

The Resource Estimation module is used for detailed resource analysis and reporting. It provides a comprehensive range of modelling-related functions; many of its block modelling tools are also used for mine planning and reserve estimation.

 

Prerequisites

Micromine Core is mandatory for all Micromine modules.

Micromine Exploration is required for essential drillhole processing and statistical/geostatistical analysis.

Micromine Wireframing is highly recommended, and becomes a requirement if wireframes are used to define ore/waste or domain boundaries.

Key Features

  • A highly optimised Vizex block model display with a very small memory footprint; on modern computers the block model graphics rendering is passed to the computer’s GPU (graphics processing unit) for increased performance. Legacy draw styles are retained for older computers.
  • Support for rotating block axes to any 3D orientation
  • Models that may comprise any combination of rotation and sub-blocked or regular blocks
  • Tools
    • Creating, indexing, validating and rotating block models
    • Converting imported data into a block model with rotated block axes
    • Re-blocking, combining, optimising and regularising models
    • Flattening or unfolding complex deposits
  • 3D modelling options
    • Inverse distance weighting
    • Ordinary and universal kriging
    • Indicator and multiple indicator kriging
    • Rank kriging
    • Statistical (calculates mean, median and standard deviation of samples falling within each block, without interpolating)
  • Tools for creating polygonal resource models for simple orebodies or where government regulations require polygonal models
  • Support for modelling variations
    • Multiple grade fields and variable input sample lengths
    • Multiple interpolation runs
    • Parent block interpolation
    • Anisotropy
    • Discretisation
    • Block or polygon kriging
  • Kriging options for trend removal and natural log transform
  • Tagging of blocks with number of points, standard deviation or kriging variance, average and minimum distance from the input data, kriging efficiency and slope of regression
  • Accumulation of sample weights back into the input file for assessing the relative contribution of each sample to the estimate
  • An optional verbose weighting report for advanced debugging, which lists every input sample that contributed to every block
  • 2D modelling options
    • Inverse distance weighting
    • Ordinary and universal kriging
    • Nearest neighbour
    • Minimum curvature
  • Numerous block model reporting options
    • Any number of grade ranges and any number of category fields (report is grouped by category)
    • Exact wireframe block factor calculation for regularised models
    • Creation of additional report fields at run-time
  • Automation of all modelling steps through easy-to-use macros or the more advanced Python programming language

Key Benefits

  • Available tools such as form sets (saved dialog box entries) that simplify the process of setting up a resource estimation
  • Form sets also provide a documentation trail (essential for standards-compliant reporting) and a quick and easy way to re-run a resource estimate
  • Advanced resource geologists and engineers benefit from the Python programming language, providing total flexibility to customise and automate the resource estimation process
  • Support for both regular and sub-blocked models
  • Block model tools that make it easy to convert between sub-blocked and regular models. This is essential for sharing data with other applications that do not support sub-blocking
  • Support for rotating block axes to any 3D orientation. Combined with sub-blocking this produces the best fit for the geology without requiring too many blocks
  • Simple tools for changing the rotation of a block model, for example to make it compatible with software that cannot use rotated models
  • Block model tools that make it easy to combine different models for the same project, for example an orebody model (where blocks only exist within the orebody) with a waste model (where blocks exist in surrounding unmineralised areas that may still be extracted by the mine)
  • Validation tools to ensure there are no errors in a block model
  • Import compatibility with Surpac, Datamine and Vulcan, which simplifies the use of third-party block models in a multi-application workplace

Vizex

The Resource Estimation module extends the capabilities of Vizex (Visual Explorer), a visualisation environment for displaying, querying and interactively editing multiple data layers.
