Vision: Completing the Australian Lithospheric Architecture Magnetotelluric Project by 2026 Background: The primary mission of the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP), commencing in 2013, has been to generate a 3D electrical resistivity model of the continental lithosphere from 3000 long-period MT sites spaced approximately 50 km. Progress: Since 2013 about 1400 sites have been funded and collected by multiple agencies including AuScope, Geoscience Australia and all State and Territory Geological Surveys. To date, South Australia, New South Wales, Victoria and Tasmania have been completed, most of the Northern Territory and smaller parts of Queensland and Western Australia. However, in recent years the program has slowed through a combination of covid restrictions on travel, increased costs and issues of access. The influence of the UNCOVER agenda has also softened in the last few years with the new demand for critical minerals. Proposal: A pragmatic approach to complete the AusLAMP array in a reasonable time and cost is to reduce the site spacing from about 50 km to 100 km, as shown in the figure for remaining sites. The reduction in density loses some fidelity but completes national continental coverage and provides context for higher spatial density infill grids.
