    2. Find causes of problems 
    3. Have a clear strategy for improvement


  • Course provides an overview of the sampling characteristics of an existing or unknown ore body. 
  • After completing this course you should be able to quantify in graphics: 
    1. Sampling characteristics using existing data 
    2. Sampling characteristics of an unknown ore or product 
    3. Impact of highly Poisson skewed data
