Stavely Project

The Stavely Project, a collaboration between Geoscience Australia and the Geological Survey of Victoria, is a contribution to the broader UNCOVER initiative, which is being led by the Australian Academy of Science. The initiative seeks to address the challenges of 'greenfield' exploration in under-cover areas in Australia through the provision of pre-competitive fundamental geoscience data and concepts.

In partnership with the Deep Exploration Technologies Cooperative Research Centre (DET CRC) fourteen drill holes were completed for 2708.5 metres to test regional geological interpretations, determine the depth and nature of cover and to recover material for subsequent detailed analysis. A combination of sonic drilling to penetrate unconsolidated cover and diamond drilling in more competent rock was undertaken. DET-CRC Lab-at-Rig™ technology was deployed during drilling.

Project data will be released during 2015-2016 and will include geology, geochemistry, geochronology, hyperspectral scanning (HyLogger™) and rock property measurements acquired using the AuScope Australian Geophysical Observing System facility at the University of Melbourne.

Regional Geology of the Stavely Project

The Stavely Project is located within the known southern extent of the Stavely Arc, which comprises several belts of Cambrian volcanic rocks and related intrusives. Rocks of the Stavely Arc are exposed at the surface in several locations in the southeast of the project area. However, the majority of the arc is concealed by a veneer of younger sedimentary and volcanic rocks.

A number of known historical mineral prospects are associated with the volcanic belts exposed at surface, several of which are currently being actively explored for copper and associated metals. The rocks of the Stavely Arc have been studied where these occur at the surface. However, the potential of many of the covered belts remains untested in a new search space identified under cover. Opportunity exists for new discoveries of economic mineralisation underneath cover, given the geological setting of the Stavely region and the known mineral potential.
