CAIRO - Egypt will offer firms royalties of up to 20% under new mining regulations issued on Wednesday, the cabinet said in a statement.

The government hopes the new law will unlock investment in Egypt's vast mineral wealth, which has been stalled by what miners describe as some of the world's most discouraging terms.

Under the regulations a committee will decide on royalties for different raw minerals ranging from 5% to 20% based on annual production, the statement said.
