Phase-1 data, that is, contractor quality-controlled and quality-assessed data for Kombolgie, were released during 2009. New EMFlow data, that is data generated using a new EMFlow version are included in this data release. The data and products described in this report are contained on the accompanying DVD.

The main products included in this data package include: sections, conductance grids and an AEM Depth of Investigation grid. The data is provided in formats which can be viewed on most computer systems. They include, JPEG (.jpg) with associated world files for easy use in geographic information system (GIS) packages, ER Mapper grids (.ers), ESRI shape files (.shp) of the flight path, and point-located ASCII data with relevant metadata for derived products.

The outcomes of the Pine Creek AEM Kombolgie survey include mapping of subsurface geological features that are associated with unconformity-related, sandstone-hosted Westmoreland-type and Vein-type uranium mineralisation. The data are also capable of interpretation for other commodities including metals and potable water as well as for landscape evolution studies. The improved understanding of the regional geology to greater than 1500m resulting from the enhanced EMFlow survey results will be of considerable benefit to mining and mineral exploration companies.

Data quality

Lineage:

The AEM survey data were acquired and processed by the airborne geophysical survey contractors Geotech Airborne Pty Ltd. Details on the acquisition and processing are available in Carter et al. (2009), which is included in the dataset. The data was reprocessed to 2 km with EMFlow software details included in the dataset.

Positional accuracy:

Positioning was via post-processed differential GPS methods. Horizontal positional accuracy of the data is approximately 1 metre (standard deviation).

Attribute accuracy:

The data have been acquired and processed to a standard of best practice as of the year 2009. More sophisticated processing algorithms may be applied to these data should they become available.

Logical Consistency:

Not applicable.

Completeness:

The dataset includes all final data and products created by Geoscience Australia using survey contractor Geotech data.
