A WA company, Loupe Geophysics, has developed a new instrument to map electrical conductivity in the near-surface to a depth of around 25 metres. The instrument, called ‘Loupe’, is a backpack-mounted two-man portable system that measures conductivity over a range of depths while the operators are walking. Data collection rates of around 5-6km per hour are possible. Loupe Geophysics is a project founded by Greg Street and Andrew Duncan, two Perth-based veterans of the geophysical instrument business. Mr Street has been working with geophysical systems in mining, groundwater and environmental applications for 40 years and Mr Duncan is the owner of Electromagnetic Imaging Technology (EMIT), the developer of equipment that has been responsible for a considerable amount of the recent…

AS Australia’s greenfield outcropping and sub-cropping deposits become increasingly scarce, miners are digging deeper than ever before, exploring new options on green and brownfields tenements. To do this, they must be able to look further underground to map the subterranean deposits before expensive exploratory drilling programs can take place. Geophysical technology allows explorers to do just that – giving explorers high resolution 3D models of up to 3km below the surface. According to Independence Group (IGO) chief geophysicist, Andrew Fitzpatrick, “the new frontier is exploring undercover”. Mr Fitzpatrick spoke with the Australian Mining Review about the way IGO has been using geophysical methods and technologies on the company’s Nova deposit, and its satellite Albany Fraser copper-nickel project in WA.
