MTS considers database integrity to be of paramount importance. Location data (collar and downhole surveys) should be error-free. Error rates in geochemical, density, and geological tables must be <1% to satisfy industry standards. Geochemical and geological data must be properly flagged for use/do not use. And, the right data must be stored in the database and accessible for geological modeling and Mineral Resource estimation.
In the attached article, Dr. Ted Eggleston of MTS sets out considerations when undertaking quality assurance (QA) and quality control (QC) evaluations (collectively QA/QC) on upload and storage of information in a project database.
