After emerging from the resources wilderness thanks to its world-class geology and industry-friendly government policies, South Australia is now a leader in Australian mining and hydrocarbon developments over the last decade. In little more than a decade the State has gone from four operating mines to more than 20 and is rated Australia’s second most popular exploration destination. With a comprehensive review of the Mining Act under way, the State’s attractiveness as a place for resources and energy investment is expected to be strengthened. South Australia is now a leader in the exploration for next generation energy sources with companies such as Santos and BP leading the charge, while initiatives such as the Government’s Copper Strategy – designed to treble annual copper production to 1 mtpa – is set to establish the State as one of the world’s premier producers of the red metal. In the energy space, uranium and nuclear energy is another area of keen interest, with the South Australian Government initiating a Royal Commission into Participation in the Nuclear Fuel Cycle in 2016. The State has become synonymous with innovation, cutting-edge development and a remarkable rate of discovery. From uranium prospects, to geothermal energy and the buoyant hydrocarbons sector, South Australia is now a leader in the exploration for next generation energy sources. With full support from the Department of State Development, the South Australian Resources and Energy Investment Conference will continue to showcase this burgeoning sector in 2017. From copper plays in the Gawler Craton, to iron ore and graphite developments on the Eyre Peninsula and the emergence of the State as a new hydrocarbon frontier, South Australia’s resources potential is at last being fully recognised. The conference will feature the success stories and emerging players in the State from both minerals and oil and gas and will also tackle thorny industry issues such as infrastructure, corporate social responsibility and the future of the Woomera Prohibited Area.

- 1. PACE COLLABORATIVE DRILLING THE STORY SO FAR Stuart Robertson EXIT
- 2. PACE COLLABORATIVE DRILLING SA Government Funding For Exploration Drilling Why? • Increase exploration drilling metreage • Development and testing of exploration concepts • Assist exploration through sediment and regolith cover • Improve exploration relevant information base for SA • Improve perceptions of prospectivity • Accelerate discovery - drilling is the key to discovery
- 3. PACE COLLABORATIVE DRILLING The Program • Total collaborative drilling budget $1.7 m per year for 5 years from 2004–5 to 2008–9 • Funding for up to 50% of total drilling costs but not other project costs • Projects assessed against geological and economic criteria • Projects managed by proponents in consultation with PIRSA. • Early release of results encouraged – maximum 3 months confidentiality after completion subject to ASX requirements • Guidelines and Assessment criteria on PIRSA Minerals Website
- 4. PACE COLLABORATIVE DRILLING Year 1 Program • Call for Year 1 proposals and announcement of approved proposals July – September 2004 • 28 Year 1 Projects approved for completion by June 2005 • Results available for 5 Year 1 Projects • Completion slower than expected due to Land Access and Operational difficulties particularly availability of drilling rigs • In future possible ‘Bundling’ of project metres to attract more drilling rigs to SA
- 5. • Call for Year 2 proposals and announcement of approved proposals February – April 2005 • Total 42 Year 2 Projects approved • 11 Year 2 drill ready Projects approved for ‘fast track’ completion by June 2005 • 31 Year 2 Projects approved for completion by June 2006 PACE COLLABORATIVE DRILLING Year 2 Program
