BUENOS AIRES - A judge in Argentina ruled to keep Barrick Gold Corp's operations at Veladero mine suspended, saying repairs were not sufficient to reopen it after a leak of processing solution containing cyanide earlier this month.

Judge Pablo Oritja's decision was based on a report from mining police in San Juan province that found the Toronto-based company had not installed security cameras and sensors as required, state news agency Telam said on Friday.

A spokesman for the province said Oritja had extended the temporary suspension of operations on Thursday until Barrick completes additional work.

A Barrick representative in Argentina said the company had not been notified of the decision.

Telam said Oritja would go on vacation on Friday, meaning another judge could handle the case.

Barrick, the world's largest gold producer, announced the spill at Veladero, one of its five main mines, on Sept. 15. The province had fined the company nearly $10 million for a September 2015 leak.

Barrick President Kelvin Dushnisky told Reuters on Sept. 19 that he thought the mine could start operating again in two weeks.

The repairs would include lifting a berm, or raised bank, over which the processing solution flowed, he said at the time.

Barrick has not said how much processing solution was spilled. Tests by United Nations investigators in October showed the year-earlier spill had not contaminated local water supplies.
