Rann is leading a business delegation to China visiting Beijing, Shandong and Jinan and will meet local mining bosses on Wednesday.
He will tell them South Australia has 50 per cent of the world's known uranium resources and major deposits of copper, gold, iron ore, zircon and other minerals.
With China's decision to massively expand its nuclear power program, SA was well placed to benefit, Rann said.
"In addition to the giant Olympic Dam uranium resource, we have a range of new uranium mines being developed and proposed, plus 81 uranium exploration licences now issued in South Australia," Rann said.
"Overturning the Australian Labor Party's national no new mines uranium policy means the brakes are off and South Australia is way ahead of other states.
"But we are also talking to the Chinese mining industry about joint ventures with Australian companies in developing South Australian mines.
"China is the key to South Australia's mining exports growth which will generate tens of thousands of jobs."
Rann said over the next 18 months, South Australia expected to roll out more than $1.7 billion in extra mining production.
"All of this work will boost jobs, exports and economic growth," he said.
