Tanzania's National Environment Management Council issued an environmental protection order relating to pollution from the mine's tailings dam.

[15] The International Council of Jurists said, after a September 2017 visit to the North Mara mine, that they were “deeply concerned about the gravity of many of [the] allegations and the difficulties [victims] experienced in accessing any adequate remedy and reparation”.

Afterward, four women who came to sit by the girl's body were injured by teargas canisters as the police sought to disperse the crowd.

[18] In June 2019, Acacia's grievance process at the North Mara mine was found to not comply with the United Nations Guiding Principles on Business and Human Rights, the international standard for corporations.

Jerry Minja, a district land officer who received cash payment, stated that his agreement prevents him from commenting on the details of the arrangement.

[21] The Wall Street Journal reported in 2018 that the British Serious Fraud Office had opened an investigation in Tanzania, despite insistence that the payments were legal.

[24] John L. Thornton told The Globe and Mail that “Acacia never paid a dime of income tax” to the Tanzanian government.

The committee found that the exports included amounts of undeclared sulfur, iron, iridium, titanium and zinc.

[29] Shortly after Thornton's deal with Magufuli was announced, Acacia's top executives – CEO Brad Gordon, CFO Andrew Wray and COO Mark Morcombe – resigned.
