New information about rock depth in Gawler Craton a boost for mining exploration

07 August 2018

SA Government: New information released today about the depths of prospective source rocks in the Gawler Craton will pave the way for more accurate and less cost prohibitive exploration.

Officially opening the South Australian Resources and Energy Investment Conference (SAREIC) in Adelaide, Minister for Energy and Mining Dan van Holst Pellekaan said this is the first data release of rock depth from the Gawler Craton Airborne Survey.

“This free package of enriched analytical data aligns with historical drilling results captured from one of the Survey’s first focus zones in the North Western Gawler Craton,” said Minister van Holst Pellekaan.

“This information, from the Geological Survey of South Australia (GSSA) and the CSIRO, will give explorers a head start on their exploration programs and save precious time and money.

“When it comes to exploring undercover, knowing the depth of prospective rocks is critical, given the cost and expense involved in drilling.

“This project is an international standout bringing an amazing clarity and precision in seeing through earth’s cover.

“We expect this will help stretch exploration dollars further and boost the chances of exploration success.”

Today’s release is the first of 16 packages the Geological Survey will roll out in the next 12 months covering the remaining Gawler Craton survey, and builds on previous releases of magnetic, radiometric and digital elevation data across a vast region of South Australia.

The GSSA has worked closely with survey contractors to ensure the highest possible levels of quality and integrity from the raw survey data.

The information is available on two open platforms, the Gawler Craton Airborne Survey Community Information website and SARIG
