The mineral exploration expenditures have risen since new millennium, but the discovery rates have not significantly improved. The discovery costs have been rising and have doubled in the last decade. Mineral industry have to progressively explore under deeper cover. The grim situation of mineral exploration promoted the development of geophysical technology, and has made great advances in the aspects of instrument equipment, data interpretation and inversion, potential application and improved success rate in discovery:higher sensitivity and accuracy, seamless collection of multiple data types, more accurate interpretation, greater the detection depth, a wider range of applications and improve the success rate of discovery. At the same time, the geophysical exploration methods have fully been using the latest achievements of information technology, and integrating with geology and other exploration methods in order to enhance the detectability and effectiveness of mineral exploration.
