Broken Hill Exploration Initiative Conference 2003

Broken Hill Entertainment Centre

July 7-9, 2003


I wish to draw to your attention the upcoming BHEI2003 conference to be held in Broken Hill next month.

This will be the sixth BHEI conference and promises to be a key event in furthering the understanding of the mineral systems of the Curnamona Province.

The Broken Hill Exploration Initiative is a collaborative venture between NSW Department of Mineral Resources, Primary Industry and Resources South Australia and Geoscience Australia. Also associated with the BHEI are the Cooperative Research Centres for Landscape, Environment and Mineral Exploration and Predictive Mineral Discovery.

The conference program will cover several themes, including wide-ranging studies of the Curnamona Province, copper-gold mineralisation, new airborne technologies, regolith studies, opportunities around the Curnamona margins, lead-zinc mineralisation in the Broken Hill Block and tectonic evolution of the Willyama Supergroup. Highlights include the latest information on geochronology, lead isotopes, first images from the Falcon airborne gravity survey, interpretation of hyperspectral data, and an account of operations by Perilya and Consolidated Broken Hill since their takeover of the Broken Hill mining leases.

A four-day pre-conference excursion will be held, covering the Olary district in South Australia and the Broken Hill Block, New South Wales. The excursion will focus on mineralisation, especially gold and copper prospects plus associated hard rock and regolith geology. On Sunday 6th July drill core from the province will be laid out for inspection and Ian Plimer will lead two short tours of the Consolidated Broken Hill leases. Following the conference there will be a three-day excursion to see the Proterozol-Palaeozoic and regolith geology of the Koonenberry region, north of Broken Hill.

For registration and general enquiries for the conference please contact Kevin Capnerhurst by phone on (02) 6392 6331, or via E-mail:
