Reserves and resources are the only significant asset that a mining company owns. All other plant and equipment is worthless if the resource is absent or lacking. For this reason it is vital that resource estimates be as precise as possible and that the individuals responsible for defining the resource be highly trained. To quickly train individuals new to resource estimation and to reinforce an expand the training of experienced personnel CRM provides three one-week training courses: Statistics and Variograms, Kriging and Uncertainty, and Conditional Simulation.
The first course, Statistics and Variography, will demonstrate the steps necessary to define and separate geological populations for estimation. This is the critical step in resource estimation. One these populations have been defined, the methods of measuring and modeling correlation using the variogram will be demonstrated.
Statistical and geostatistical concepts are not difficult, but it is usually not possible to fully appreciate and later apply these concepts by simply listening to lectures. Practice is required to reinfoce the lectures and ensure that the material has been absorbed. For this reason, nearly half of the time in the course is spent solving and discussing real problems based on actual data. Course participants are encourages to bring their own data set as at the end of the course each attendee will apply the techniques presented and discuss the results.
