GeoX Prospect Assessment Fundamentals

This three-days course is focused on providing attendees with an overview of the methods required for assessment of the risks and uncertainties within a contemporary prospect evaluation. Participants will learn the principles and concepts that should be applied when assessing both simple and complex prospects.

Delivered in a workshop style, the course combines lectures on the principles of stochastic volume calculation, pre-assessment data collection and analysis; manual volume calculations exercises and exercises using the GeoX software suite to illustrate the analytical methods used to assess the risks and uncertainties of an exploration prospect. In the last session of the course the participants will use a case study to run their own GeoX prospect assessment.
