Geological data and information
The Stavely Project, a collaboration between the Geological Survey of Victoria and Geoscience Australia, 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' minerals 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 rock samples for subsequent detailed analysis and research.
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 one of several techniques deployed during drilling.
Regional Geology of the Stavely Arc
The Stavely Project area is located within the known southern extent of the Stavely Arc, which comprises several belts of Cambrian volcanic rocks and related intrusions. Rocks of the Stavely Arc are poorly exposed in just a few locations in the southeast and west of the project area. The majority of the Stavely Arc is concealed by a veneer of younger sedimentary and volcanic rocks.
A number of known mineral prospects are associated with exposed portions of the volcanic belts, 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 untested and the new pre-competitive data and knowledge has resulted in a new search space under cover.
Opportunity exists for new discoveries of mineralisation under cover, given the geological setting of the Stavely Arc and the demonstrated mineral potential.
