Abstract
SummaryA significant stage in mineral reconnaissance exploration can be performed on the Internet, using publicly available geophysical images overlaid with known occurrences of the commodity being sought.Using the Mineral Occurrences Database of the Northern Territory on various images available on the NTGS' Geophysical Image Web Server allows useful patterns to emerge. Similarly, patterns predicted by the user's previous stage of reconnaissance are tested against these public domain images. Lessons arising from this exercise improve the quality of the user's predictions for the next stage of exploration.Patterns emerge when occurrences are compared with the images of the radiometrics soil map, vertical derivative, surface relief and so on. Associations are demonstrated with examples from the Kombolgie, Kalkarindji and Bitter Springs formations.
