the assessment was to determine if DRX could
improve the conversion efficiency of a volume of
ground from the Indicated to the Measured
category
Of particular interest to the company was
DRX’s capability of producing a number of
drilling plans based on varying budgets. Each of
the drilling plans had to meet all project
constraints while maximizing the indicated to
measured conversion rates.
Creating a number of valid options enabled
the company to select the appropriate plan that
best aligned with its strategic goals and
budgets.
When compared to the manual layout, the
DRX solutions provide a means of drastically
improving conversion rates. This increase in
resource conversion efficiency has the potential
to save money but more importantly it saves
time, both in drilling and setup. The DRX-3
solution not only decreases the total number of
drill holes, but also improves drilling times.
Deployed as a Microsoft Excel add-in,
ThreeDify Excel CoreBlock (XLCoreBlock) is a
Microsoft Excel based drill hole visualiser and
quick resource estimator. The company says
that “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 provides mining professionals
with a quick, easy and cost-effective way to
visualise, validate and analyse drill hole data in
3D directly within Microsoft Excel.”
The CoreViz Module allows its users to
visualise 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
modelling 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 Key Benefits
n Easy-to-use: visualise and analyse your drill
hole data in 3D, and conduct quick resource
estimation within your familiar Microsoft
Excel interface
n Automatic: automated interpolation of block
model grades and attributes for both single
and multi-mineral deposits using 3D
anisotropic RBF interpolators that
