(Adds details from Barrick statement)
BUENOS AIRES, May 29 (Reuters) - One of several labor unions at Barrick Gold Corp's Veladero mine in Argentina have gone on strike, the company said in a statement on Monday, adding that it is meeting with union leaders to reach a "timely" resolution to the situation.
A source from the union, who asked not to be named, told Reuters that talks were ongoing. The source declined to say what the complaint was that led to the work stoppage on Sunday.
The government of Argentina's San Juan province, where Veladero is located, said earlier this month that it had approved a plan for improving safety following the facility's third spill of cyanide solution in 18 months.
Leaching activities at Veladero have been restricted since March 29, the Canadian company said in its statement. There was no change to the expected timeline for resumption of normal leaching activities in the second half of June, it said.
