Workshop:  Worldwide Mineral Exploration Challenges and Cost-Effective Geophysical Methods


Peter Holmes (Uppsala University), Michal Malinowski (Institute of Geophysics PAS) & Suvi Heinonen (Geological Survey of Finland)

Room: San João


Workshop Description 

The workshop “Worldwide mineral exploration challenges and cost-effective geophysical methods” aims to bring industry and academia together for knowledge transfer and discussion about novel ideas to solve the global challenges in mineral exploration. Nowadays it is well understood in exploration that one geophysical technique is rarely sufficient to identify new ore deposits especially under cover. Each method applied, let it be potential fields, EM or seismic, progressively adds more information toward making the most important decision to drill-test targets. The workshop will discuss ways to improve the interpretation of geophysical anomalies leading to better defined exploration targets and cost-effective usage and integration of different geophysical methods.

The exploration industry is facing the same challenge all over the world and useful geophysical methods are dependent on commodity type instead of geographical location. A common denominator for different deposit types is that new deposits need to be discovered at increasing depths which creates an immediate need for development of innovative geophysical methods and their novel integration.

We are seeking contributions from both academia and industry addressing the need to develop cost-effective geophysical methods for mineral exploration. We are expecting hands-on contributions discussing openly about resources required for certain exploration workflows to be efficient, both in terms of funding and time as well as availability of service providers and skilled personnel. The workshop welcomes presentations about different geophysical techniques such as electromagnetic and potential field applications, seismic methods and measurement systems utilizing passive or active sources and different platforms such as UAVs or well-logging tools. We welcome contributions on new methods development as well as on exploration problems that the geophysical community needs to solve in order to stir the discussion.
