 Commercial exploitation of the Sadiola gold mine began in 1996, with the nearby Yatéla mine opening in 2001.The two mines are collectively owned under the consortium (38% and 40% shares, respectively, to each of IAMGOLD and AngloAmerican Ashanti), with smaller shares held by the Government of Mali (18% and 20% respectively) and the World Bank's International Finance Corporation (6% for Sadiola only).The terms of IAMGOLD's and AngloGold Ashanti's joint venture stipulate that the day-to-day operations are the administrative responsibility of AngloGold Ashanti, and AngloGold Ashanti collects an additional 1% of Sadiola's revenue for this service.
