New online GIS highlights nickel potential

4 June 2003

Location of Harris Greenstone Belt in South Australia

A new interactive GIS, released by Geoscience Australia in association with Primary Industries and Resources South Australia, highlights significant potential for nickel, copper and cobalt in the Harris Greenstone Belt, central Gawler Craton of South Australia.

The GIS highlights the extensive distribution (300 km strike extent) of poorly exposed Archaean komatiites (about 2 500 million years old) and associated rocks with potential for nickel, copper, platinum group elements and lode-gold mineralising systems.

Layers included in the new GIS are: interpreted Precambrian basement geology, which is based on aeromagnetic, gravity, and diamond drilling data; mines and mineral prospects, with information extracted from the MINLOC database; drill holes; cultural features; and various high-resolution total magnetic intensity, bouguer gravity, Landsat Thematic Mapper, airborne electromagnetic, and digital elevation model images.

You can download a map of the Harris Greenstone Belt and the digital data for the new online GIS from the Gawler Mineral Promotion: Maps and Online GIS page. This page also contains links to other Gawler Craton maps and online GIS's.
