A resources precinct will be built at the Tonsley former Mitsubishi site in Adelaide, under a re-elected South Australian government.
Premier Jay Weatherill on Wednesday said the precinct, to include a $32 million State drill core library, was aimed at accelerating investment in exploration and development of SA's resources sector.
Minerals and energy companies operating in the state planned to create an additional 35,000 jobs over the next 15 years, he said.
"Our policies will help companies accelerate the pace of job creation not just at the mine site or well head but also in the service industries that will support our energy sector," he said.
As well as the core library, the plan includes an onshore petroleum centre of excellence.
The Liberals later released a document, said to have been leaked from Cabinet, which opposition spokesman Rob Lucas said undermined Labor's costings for the library.
Opposition Mineral Resources and Energy spokesman Martin Hamilton-Smith said the announced precinct would not repair the damage being inflicted on SA's resources sector by the Minerals Resources Rent Tax and carbon tax.
"Premier Weatherill needs to take his head out (of) the sand and acknowledge that federal Labor's investment killing taxes must be repealed immediately," he said.
South Australians go to the polls on March 15.
