SYDNEY, Sept 29 (Reuters) - BHP Billiton BHP.AX BLT.L said a massive blackout in South Australia has forced it to halt production at its Olympic Dam copper, gold and uranium mine to divert back-up power to maintain essential operations at the remote site.
A BHP spokesman did not say when operations would resume.
Severe storms and thousands of lightning strikes knocked out power to the entire state of South Australia on Wednesday.
