Tenzing has a proven track record in staff training in the pragmatic use of geostatistical concepts, in particular in the form of hands-on one on one co-piloting session using the specialised geostatistical toolbox Isatis.

Tenzing also has experience in teaching introductory and advanced geostatistical training courses to the coal and metalliferous mining industry (~25 courses since 1999) as course leaders and/or course co-presenters.

Tenzing offers two types of training:

• Short courses covering introductory geostatistics to advanced geostatistical methodologies;
• Hands-on one on one training covering both geostatistical theory and practical examples (client or site based) using the specialised geostatistical toolbox Isatis.

The outline of a typical course would be as follows:

Day 1

• Isatis software installation;
  
• General introduction;
  
• Importing comma delimited files with and without header files;
  
• Exporting comma delimited files with and without header files; and,
  
• Data Selection – covering in detail interval selections, alphanumeric selections, logical operation selections (AND, OR, NOT, EX OR), sampling selection and macro selections;
  
• Copy statistics operations covering the points grid and grid operations; and,
  
• Calculation operations.
  

Day 2

• Grid creation for two dimensional estimation and for statistical homogeneity analysis;
  
• Quick statistics operations reviewing univariate, bivariate and multivariate operations;
  
• Exploratory Data Analysis (EDA) covering base maps, scatter plots, histograms, grade tonnage curves, q-q plots, h-scatter plots, variograms and variogram maps. In addition, the editing, saving and printing of the statistical figures was reviewed;
  
• Generation of experimental variogram maps; and,
  
• Generation of experimental omni-directional variograms and directional variograms.
  

Day 3

• Review of the Isatis processes learnt over Days 1 to 3 by performing statistical homogeneity analysis, exploratory data analysis and variographic analysis based on a seam from deposit datasets;
  
• This process follows the typical geostatistical workflows used by Tenzing in coal projects;
  
• Review of the drillhole spacing analysis procedure (DHSA);
  
• Review and interpretation of the DHSA Excel spreadsheet; and,
  
• Review of the (co)kriging ope
