3-D Geological Modelling Workshop (GSSA)

Recent trends in mining and exploration are set to further accelerate the demand and growth of 3D geological modelling software. These trends include the inevitable increase in cost per ton of resource and global economic slowdowns. These require companies to constantly cost-cut during extraction and to improve resource delineation. Add to this the trend that new discoveries are deeper and in more structurally-complex setting, and it’s apparent that a great deal of attention needs to be focused on getting the geometry of a deposit, as early as possible in the exploration and mining value chain, correct.

About this event

Recent trends  in mining  and  exploration  are set to further accelerate the demand and  growth  of 3D geological  modelling software.

These trends  include  the  inevitable  increase  in cost per ton of resource and  global economic slowdowns.   These  require companies to constantly cost-cut during    extraction  and   to  improve  resource  delineation.   Add   to  this  the  trend  that  new discoveries are  deeper and  in  more  structurally-complex  setting,  and  it's  apparent that a great deal  of attention  needs  to be focused on getting  the geometry of a deposit, as early  as possible in the exploration  and  mining  value  chain, correct.

The  versatile  application  of well-built,  validated  3D  models  is  one   of  the  most  important  tools  for achieving  this  and  forms the  basis  for  all  downstream  processes.    From  the  point of view  of drillhole targeting,  resource  extension,  geotechnical  design,  infrastructure  and  cost simulation,  pre- and   post• blast  surveying,  geohydrological  simulations,  truck  and   bucket  volume   calculations  and   many  other routine  mine  tasks,  3D models  are  a common and  necessary denominator.

The past decade has seen  a tremendous growth in the capabilities of almost all commercial 3D geomodelling packages, to the  point where they run on high-end  PCs.   This growth  has changed the complexion of mineral exploration and  mining;  there is now  a huge  overlap in terms of basic volume    modelling   and    manipulation   between   commercially-available,   general    modelling packages and  those specifically tailored for use in geology and  mining.  Recent trends are  away from  software packages that have  unforgiving data import routines, use explicit, section-based modelling  and  which  incorporate  limited  data  sets  or  types.    The  trend  is  towards software packages that have  flexible import routines;  rapid, dynamic, implicit modelling of surfaces and shells,  integration  of large  numbers  of disparate data sets and  3D querying of spatial  data to determine trends and  patterns.   These typically incorporate  an easy, workflow-driven  approach.

Speakers

Dr Ian Basson
Ian qualified with a Ph.D. in Structural Geology from the University of Natal (now Kwazulu-Natal) in 2000. He completed his Post-Doctoral Studies at the University of Cape Town, with a focus on the structural controls on kimberlite emplacement, in 2002. Ian is a professional structural geologist with over 20 years' experience in mapping, structural analysis and 3D modeling. His skill set includes mapping of complex structural environments, including high-grade metamorphic terranes and those with a significant brittle-ductile or brittle overprints; structural and lithological mapping of open-cast mines; translation of structural features into parameters that are used by geotechnical engineers and mining personnel in pit slope design and mine planning; 3D modeling of complex geology; lithological and structural interpretation of geophysical and Landsat/ASTER data sets; forward structural modelling in greenfields or brownfields exploration projects using stress mapping and modelling. Ian has undertaken over
150 projects for his clients and has published 52 peer-reviewed articles. He is a Senior External Lecturer at the University of Stellenbosch, where he presents the Honours Geology class with a course on general 3D modelling and a practical course in Leapfrog.
