Mali has adopted a new mining code that aims to increase the sector's contribution to GDP to between 15 and 20 percent, up from a current 9 percent.
The government announced the review of the mining code in January after it said an internal audit had shown that Mali, one of Africa's biggest gold producers, was not receiving a fair share of profits while granting too many tax breaks.
A draft of the code seen by Reuters before it was passed showed proposed changes that could boost state and private Malian interests in new projects to 35 percent, from up a current 20 percent.
It was not immediately clear whether those proposals had been enacted in the new code.
