In 2020 the GSSA ran ExploreSA: The Gawler Challenge, a cutting-edge, crowd-sourced competition where participants delved into the GSSA's open-source treasure trove of geoscience data. Their mission — to dissect, analyse, and unveil hidden mineral exploration gems using a mix of traditional techniques, artificial intelligence and machine learning.

This competition shed light on the power and untapped potential of our data, but we also realised we needed to enrich our data landscape.

Enter Gawler Phase 2 (GP2): Next Generation Mineral Systems Mapping Project. GP2 wasn't just a project, it was a quest to acquire new geoscience data and breathe digital life into the legacy data of the Gawler Craton region. The goal — to de-risk exploration and support industry investment in South Australia.

Fast forward to today and the GP2 journey is complete. We've put together a treasure trove of new data and valuable information, as well as the entire post-project workshop. You can access all the outcomes below via one link to the SARIG Catalogue.
