The Don Mario mine is located in the heart of the Chiquitano Dry Forest. This rare, globally significant ecosystem supports the headwaters of the Pantanal wetlands and is home to numerous endemic species. The Pantanal is one of the world’s largest freshwater ecosystems, recognized by UNESCO and the Ramsar Convention. The area is also of great cultural, economic and social importance to the Chiquitano indigenous people. In a complaint filed with the World Bank’s Compliance Advisor Ombudsman, an indigenous organization argued that the mine violates the rights of over 7000 indigenous communities. Among other shortcomings, the ombudsman found that indigenous people were not adequately consulted by the project proponents.
