Mineral Resource Estimation

  • INDONESIA (Jakarta): 19-23/9/22

Course Brief

This course has been designed for geologists and mining engineers involved with or are interested in becoming involved with mineral resource estimation for prospect evaluation, grade control or long-term planning.  The course requires a knowledge of geology and/or mine planning but does not require prior knowledge of geostatistics.  Participants should have computer skills associated with geology modelling, grade control or mine planning software.

The course requires the use of Microsoft Excel and geostatistical modelling software to complete the practical portion. Participants can bring their own commercial software or use ours, which will be provided for practical exercises.
