I attended a presentation by DET CRC at the Australian Society of Exploration Geophysicists concerning the principles of the project and a current status. The talk outlined the guiding principles of the program: The need to drill more boreholes in areas covered by near surface deposits which result in little or no evidence of mineralisation […]
Borehole Imaging
Borehole imaging probes are now a common service provided in boreholes drilled for mineral exploration, geotechnical investigations and groundwater programs. The major mineral borehole imaging methods are: Acoustic imaging: requires a fluid filled borehole Optical imaging: need to be able to see the borehole wall (air or clear fluid) Both methods are commonly requested on […]
