Excel Drillhole Visualizer/Resource Estimator

Deployed as a Microsoft Excel add-in, ThreeDify Excel CoreBlock (XLCoreBlock) is a Microsoft Excel based drill hole visualizer and quick resource estimator. By leveraging the popularity and ease-of-use of Microsoft Excel, XLCoreBlock has significantly lowered the learning curve and total cost of ownership for mining knowledge workers. It has become the go-to tool for field geologists, mining executives, investment banks and property owners.. XLCoreBlock consists of two modules that can be licensed separately.

The CoreViz Module allows its users to visualize and validate assays, lithology and attributes (both continuous and categorical), making XLCoreBlock a potent Excel-based QA/QC DDH validation tool.

The BlockModel Module features implicit modeling based on a very fast implementation of anisotropic Radial Basis Function (RBF) interpolation. It allows the user to quickly create and export 3D block models and iso-grade surfaces or solids. The RBF interpolator is a global, automatic resource estimator with no need for tedious variogram modelling.

XLCoreBlock provides mining professionals with a quick, easy and cost-effective way to visualize, validate and analyse drillhole data in 3D directly within Microsoft Excel.

XLCoreBlock Key Benefits

  • Easy-to-use: visualize and analyze your drillhole data in 3D, and conduct quick resource estimation within your familiar Microsoft Excel interface.
  • Automatic: automated interpolation of block model grades and attributes for both single and multi-mineral deposits using 3D anisotropic RBF interpolators that support a user-defined search ellipsoid. No complex variogram modelling is needed. Ideal for investors, fund managers and field geologists who need quick estimates for their deposits.
  • Flexible: you specify where data are in your worksheet(s). Supported data types include lithology, assay grades, continuous and categorical attributes,
  • Efficient: there are no additional files or file formats to manage as generated 3D drill hole plots and block models are directly saved as part of the Excel file from which the plots and models are created.
  • Convenient: you can also easily create AVI video animations for your 3D drillhole data and block models.
