Back to the Future: Geologic mapping provides the framework to validate and integrate data from new exploration tools

The development of new techniques in mineral exploration seems to reduce the need of geological field work and mapping: Data collection can now be done remotely by satellites, drones, and tablet-equipped field assistants, while the geologist assembles data sets with 3D software. The interpretation of complex data sets can be assisted by machine learning and artificial intelligence (ML, AI). Instead of loosing relevance, geological mapping and logging are now even more essential to provide the interpretive framework essential for the correlation, validation, and integration of huge amounts of data, but will not be replaced by new technologies. Geological truthing lies in the field, with experienced geologists conducting this work while training and mentoring young professionals.
