Data Assimilation for Resource Model Updating

One of the two core constituents of Closed-Loop Management for Mineral Resources is data assimilation for resource and grade control model updating. Similar to weather forecast models, the aim is to update the knowledge and forecast ability of the ROM ore as soon as new data from production monitoring become available. This chapter provides a formal description of the geostatistical foundations, a practical workflow and outlines one particular solution for updating. The theory is underpinned by three industrial-scale case studies and a discussion about practical aspects for operational implementation in Chap. 4.
