Learning Outcomes
- identify traditional approaches of the mineral resource estimation using manual designing of cross-sections and summarizing by spreadsheets.
- recognize the concept of block model and geostatistical methods of reserve estimation.
- interpret characteristics of the drill hole data and apply statistics and probability science to evaluate their distribution function, outliers and geological domains.
- apply mining software, Surpac, to create a comprehensive block model and wireframe modeling of the geological features and apply estimation methodologies of reserve estimation such as nearest neighbor, inverse distance, Kriging and conditional simulation.
- evaluate the quality of the estimations and standard codes of the mineral reserve estimation reports.
- determine a mineral resource estimate for a given set of drillhole/sample/geology information using both a conventional and geostatistical method by working on individual projects.
