The use of open-source codes has become pervasive over the past 20 years but such codes are uncommon in minerals exploration. The P223 series of programs researching forward and inverse modelling of electromagnetic data was supported by CSIRO and six

AEM Geophysical surveys are excellent tools for mapping conductivity variation over large areas. Common workflows involve inverting data using 1D models on a per-station basis, then gridding those results over lines to produce maps. In the absence of

The Capricorn Orogen is located in central Western Australia and includes several Proterozoic sedimentary basins. The Yerrida and Earaheedy basins are located in the south-east of the orogen and were formed, and deformed, over multiple orogenic event
