Mark SONTER

Off Earth Resources P/L

Mark Sonter is a physicist, has spent >45 years in the mining industry, in both operational and consulting roles, as ‘the grandfather’ of Radiation Management in the mining and processing of radioactive ores, having been intimately involved in planning and implementation of many uranium and rare earths projects, in Australia and overseas.

Through all this time, he has run a parallel career proselytising on the resources of the Near Earth Asteroids (his 1997 thesis on this still being quoted), and as co-founder of Deep Space Industries (2013-2017).

Mark is an Adjunct Assoc Prof at the University of Adelaide Andy Thomas Centre for Space Resources and earlier this week presented (again) at its annual intensive short course on Space Resources Fundamentals. Mark’s current space resources startup is Off Earth Resources P/L, where he and colleagues have been defining and scoping a minimal-capex commercial space resources project for early implementation.
