permission to do exploratory drilling for iron, copper and gold under the lake, intending to work with traditional owners to “preserve and protect” important sites. The area was drilled in 2007 to 2008 without obtaining permission of the Kokatha people, who then held native title (see History, above). In February 2018, the South Australian Environment, Resources and Development (ERD) Court granted authority to enter and undertake mining operations (exploration) within those parts of the western area of the lake defined in an application by Argonaut. Some drilling was done in 2019, but was paused pending a technical review relating to the

In January 2021, the state government under Steven Marshall granted permission to Kelaray to conduct drilling on the lake, over an area including Murdie Island, part of Andamooka Island, and part of Carrapateena Arm, after they had made an application under Section 23 of the ''

Mitigation strategies to protect the environment include purpose-built mats which would be used on the lake's surface to "protect the salt crust" from vehicles travelling over it, and the company intends to consult regularly with Aboriginal representatives. However Kuyani woman Regina McKenzie expressed concerns that her people were not consulted and no cultural assessments were made. The work, scheduled to begin in 2021, would "target iron oxide copper-gold ( IOCG) copper mineralisation", similar to mines at Olympic Dam and
