tested through cross-validation experiments
or direct drilling of targets.


The core tools for developing and exploiting mine-, camp-, and regional-scale 3-D common earth models for the
purpose of targeting new ore or specifi c geologic relationships are now here


Sound reasonable to these guys.....



Conclusions
New geotechnologies for the mineral exploration community
are constantly emerging, but the one key technology
that is demonstrating the ability to pull all these developments
together under one roof is 3-D GIS. It is where geological
modelling can be undertaken in a rigorous and quantitative
way. With 3-D GIS, there is an opportunity to make
data-driven or knowledge-driven predictions and interpretations
that can be tested through cross-validation experiments
or direct drilling of targets. It is an environment that, in the
coming years, will see a richer set of tools and workfl ows
for specifi c types of exploration tasks and deposit types. It is
an environment that will likely follow the same trend as 2-D
GIS has in the past, becoming more user friendly, more of an
integration tool, and developing more relevant applications
that are connected to the business case required for modern
exploration.

Mineral exploration is evolving into a more rigorous quantitative science. 3-D GIS provides support for this activity
through an environment in which a rich and diverse set of exploration-related observations can be analyzed and interpreted.
The core tools for developing and exploiting mine-, camp-, and regional-scale 3-D common earth models for the
purpose of targeting new ore or specifi c geologic relationships are now here. It is now incumbent on the industry, with its
wealth of knowledge of specifi c ore forming processes, its rich archive of 3-D data sets, and with a defi nite need to fi nd
the diffi cult and deeper ore, to capitalize on this new technology. Industry, government, and academia are encouraged to
develop partnered 3-D interpretation teams focused on interpreting multi-scale 3-D maps in mineral-endowed belts. It is
essential that these exercises are supported with appropriate human resources in order for 3-D modelling to achieve its
expected goals of enhancing the mineral targeting process and ultimately increasing mineral wealth. New technologies
are emerging for automating the model construction process, leaving the expert free to interpret and test exploration
criteria. Advances in 3-D joint geologic and geophysical inversion are also contributing to a more rigorous interpretation
workfl ow. When applied by focused multi-scale interpretation teams, this approach has great potential to make a signifi -
cant impact on enhancing near-mine to greenfi elds mineral exploration activities.
