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

System Requirements:

“… ThreeDify Excel CoreBlock is simple, effective, and best of all everything can be done within Excel. Equally as impressive as the software was the customer support… The support team was always there to quickly resolve any issue we had.”
