Rovina has measured and indicated resources of 7.2 million ounces of gold and 1.4 billion pounds of copper and the company describes it as the second-largest gold deposit in Europe.
Euro Sun was granted a mining licence for Rovina three years ago which allowed the company to begin the permitting process. Under Romanian law, the licence does not come into effect until it has been officially gazetted, the company said.
"The Secretary General of government assured management of their intention to ratify our mining licence and will submit the fundamental note to the government meeting at the earliest opportunity following the signature of the Ministry of Justice," president and CEO G. Scott Moore said yesterday.
Rovina has been the company's main focus until it made an unsolicited C$1.5 billion (US$1.2 billion) bid with Lundin Mining three weeks ago for Nevsun Resources, which Nevsun told shareholders to ignore.
Euro Sun's shares eased to close up almost 9%, or C10c to $1.22. They were trading around the 70c mark a year ago and peaked just over $2 in August.
Meanwhile, the gold price has moved a little higher as markets consider the US Federal Reserve's indications it is not going to accelerate rate hikes and fresh doubts are cast on the US-North Korea meeting going ahead next month.
