Anglogold Ashanti Ltd

AngloGold Ashanti's Obuasi mine in Ghana has been the site of at least 11 officially reported cyanide spillages between 1989 and 2003, with the frequency increasing to approximately 13 spillages by 2006. Studies documented arsenic concentrations in process effluent averaging 10.0 mg/L — well above safe drinking water standards — along with cyanide at 21.6 mg/L and copper at 3.1 mg/L. More than 52% of the population in the mining area lacks potable water. The company's arsenic contamination at the Sansu tailings dam near Obuasi has been the subject of multiple peer-reviewed studies documenting elevated heavy metal concentrations in surrounding rivers and soils.

Separately, in 2015 AngloGold Ashanti's Guinea subsidiary forcibly displaced communities near its Siguiri gold mine. When residents of "Area One" refused the company's resettlement terms, AngloGold requested the Guinean government make the land available; state security forces including the Berets Rouges carried out evictions with violence, intimidation, and arbitrary arrests. Displaced families were resettled without water, schooling, or healthcare. A six-year mediation through the World Bank's Compliance Advisor Ombudsman concluded in September 2024 with a financial settlement. Norway's Government Pension Fund Global Ethics Council recommended divestment from AngloGold Ashanti in 2013 citing serious environmental damage in Ghana.
