2nd Conference on Geophysics for Mineral Exploration and Mining

The signature of a mineral deposit can vary to different geophysical methods, depending on its mineral concentration, size and depth. For this reason, a single geophysical method in several cases could be insufficient, if the expected geophysical response is weak or the interpretation is not unique.
