Surface sample geochemistry that has been reported by title holders to the department as part of the mineral exploration reporting requirements. The data is provided annually in the form of exploration data files and stored with the relevant report in DIGS. Data mining of digital exploration data files stored in DIGS is largely complete for the period 2001 to present. Data mining continues for DIGS reports earlier than 2001 using OCR (optical character recognition) software to convert raster data into digital files for loading. Validation of data is an ongoing process. Data available to the public and industry is restricted to DIGS open file reports.
