Open file Company Mineral Drillhole Database containing historic drillholes. The database is an aid to mineral exploration in Western Australia. Under the Mining Act 1978 companies submit annual mineral exploration reports some of which contain drillhole data. This information is made available when the reports are released to the public usually after a confidentiality period of five years. As a minimum, available drilling data comprises a collar file validated against the tenement outline. Additional files such as assays, geology and surveys may also be available depending on the company's submission

The 1:500 000 State interpreted bedrock geology (DMIRS-016) is one of three digital data layers that make up the 1:500 000 geological map of Western Australia. The other two are the 1:500 000 State Cenozoic geology and the 1:500 000 State linear structures layer (DMIRS-015). Compilation is based on published 1:100 000 and 1:250 000 Geological Series maps of Western Australia, together with GSWA and GA (AGSO, BMR) regional geological maps at scales from 1:250 000 to 1:1 000 000. Information from these maps has been modified locally using geophysical datasets (magnetics, radiometrics and gravity), remote sensing imagery (ASTER and LANDSAT), seismic and magnetotelluric profiles, drilling, and unpublished geological mapping. The nomenclature and hierarchy for the lithostratigraphic units are based on the GSWA Explanatory Notes System (extracted April 2016). Data are held in GDA94 decimal degrees. This dataset was formally known as 1:500 000 State interpreted bedrock geology (DMP-013)

The 1:2 500 000 State interpreted bedrock geology structural lines (DMIRS-013) is one of four digital data layers that make up the 1:2 500 000 geological map of Western Australia. The other three are the primary 1:2 500 000 State interpreted bedrock geology, the 1:2 500 000 State Cenozoic geology, and the 1:2 500 000 State interpreted dyke suites. The attribution of linear structures and dykes as concealed or exposed takes into account both the interpreted bedrock and the Cenozoic geology layers and does not reflect regolith cover. Detailed fault attribution has been simplified from the 1:500 000 scale, except in the case of major fault systems or tectonic boundaries. The data are held in GDA decimal degrees. © State of Western Australia 2018 Department of Mines, Industry Regulation and Safety (DMIRS).

The primary 1:2 500 000 State interpreted bedrock geology (DMIRS-014) is one of four digital data layers that make up the 1:2 500 000 geological map of Western Australia. The other three are the 1:2 500 000 State Cenozoic geology, the 1:2 500 000 State interpreted dyke suites, and the 1:2 500 000 State interpreted bedrock geology structural lines (DMIRS-013). The 1:2 500 000 interpreted geology contains geoscience data covering themes such as geology and tectonic boundaries that have been digitally rolled up from 1:500 000 data sources for optimal display at 1:2 500 000 scale. The Cenozoic geology layer can be superimposed over the bedrock layer to allow the interpreted extension of older bedrock geology under Cenozoic cover, where geological and geophysical information permits, and to depict Cenozoic paleovalleys and additional significant Cenozoic cover. The nomenclature and hierarchy of lithostratigraphic units is based on the GSWA Explanatory Notes System (extracted September 2015). Stratigraphic units are mostly displayed at greater than or equal to Group or Suite level; Subgroups and Formations are only displayed where areal extent warrants it and the unit does not have a higher order parent. The data are held in GDA94 decimal degrees. This dataset was formally known as 1:2 500 000 State interpreted bedrock geology (DMP-011)

The 1:500 000 State linear structures layer (DMIRS-015) is one of three digital data layers that make up the 1:500 000 geological map of Western Australia. The other two are the 1:500 000 State interpreted bedrock geology (DMIRS-016) and the 1:500 000 State Cenozoic geology. The linear structures layer refers primarily to pre-Cenozoic structures, and attribution of concealed structures refers to those that are older than the pre-Cenozoic unit in question. Compilation is based on published 1:100 000 and 1:250 000 Geological Series maps of Western Australia, together with GSWA and GA (AGSO, BMR) regional geological maps at scales from 1:250 000 to 1:1 000 000. Information from these maps has been modified locally using geophysical datasets (magnetics, radiometrics and gravity), remote sensing imagery (ASTER and LANDSAT), seismic and magnetotelluric profiles, drilling, and unpublished geological mapping. Data are held in GDA decimal degrees. This dataset was formally known as 1:500 000 State linear structures layer (DMP-012)

Geoscience Australia’s Exploring for the Future (EFTF) program aims to enhance decision-making on Australia's mineral, energy, and groundwater resources by providing comprehensive geoscience data. Launched in 2016 with a $225m investment, the program has spawned various national projects, including the Australia's Resources Framework (ARF). The ARF focuses on a national perspective of Australia's surface and subsurface geology, supporting economic and social benefits, including transition to net-zero emissions. One key sub-project within EFTF is the Geochemistry for Basin Prospectivity (G4BP) module. It explores Australian basins for basin-hosted base metal systems. The current focus (2020-2024) is on the Stuart Shelf region in South Australia, in collaboration with the Geological Survey of South Australia (GSSA) and CSIRO. The efforts aim to refine our understanding of sediment-hosted copper-cobalt-silver (Cu-Co-Ag) potential in this area. This work has two primary objectives: Geochemical fingerprinting and baseline data collection: Comprehensive data collection and reanalysis of existing samples aim to establish baseline geochemistry for stratigraphic units. Mineral system components: Identification of potential metal sources, fluid sources, and trap rocks using a mineral systems approach. This data release forms the second stage release of new geochemical data for the Stuart Shelf region; the first stage release was detailed in Champion et al. (2023b). There is also an earlier data release (Champion et al., 2023a) featuring reanalysis, by modern analytical methods, of legacy mineralised and/or altered Stuart Shelf and underlying basement samples held at Geoscience Australia.
