The royalty increase is meant to increase state budget revenue, the ministry said.
Authorities will also increase to 6% the royalty for mineral resources included in the Mining Law.
The royalty for natural mineral waters is set at the source, in the equivalent of EUR6 per thousand liters, calculated at the central bank exchange rates on the date of payment.
The ministry expects these increases to bring an additional 117 million lei (EUR27.46 million) to the state budget this year and RON1.1 billion over the next four years. (EUR1=RON4.2611)
