The Mineral Systems Drilling Program was a collaborative drill program managed by the Geological Survey of South Australia in partnership with the Deep Exploration Technologies Cooperative Research Centre, Minotaur Exploration, Kingston Resources and several service providers. From July 2015 to April 2016, 14 diamond drillholes were completed for a total of 7,868 m. The objective was to further the understanding of mineral systems developed during c. 1590 Ma magmatism, with particular emphasis along the southern Gawler Ranges. This articles summarises the contributions to scientific objectives which have been made through improvements to geological knowledge of the regional stratigraphy and lithological variation, deposit models, alteration styles, regional controls on fluid flow and mineralisation, and in providing new constraints on the depth to base of the Gawler Range Volcanics.
