The company didn’t give a starting price for the auction.
Cupru Min is Romania’s largest copper producer and owns around 60% of the country’s estimated copper reserves.
The Economy Ministry is hoping to float a stake of 15% in Cupru Min in Bucharest next year.
The government has been trying to privatize the company for several years, but with no results. In 2012, Canadian-based Roman Copper Corp. won an auction to purchase Cupru Min, but the government cancelled the auction, citing contractual disagreements.
Last year, the authorities changed tactic and tried to sell over 331,000 tons of copper concentrate mined by Cupru Min, but the auction fell through, as the two qualified investors did not submit binding bids.
