A Data Mining Approach to Validating Drill Hole Logging Data in Pilbara Iron Ore Exploration

摘要

Logging of exploration drill holes is a routine practice, and its accuracy is essential for resource evaluation and planning in the minerals industry. Logged compositions record a set of material types with standardized mineralogy and texture characteristics. The material types logged may vary due to diversity in mineralization and geology, but also due to subjective biases and human error, leading to significant challenges for the industry. Thus, there is a need to validate the field logging whereby the material types and their percentages are adjusted to reconcile with laboratory assay values while retaining the physical characteristics and geologic context.
