"Due diligence: Our mines conduct human rights assessments on a two-year cycle. In the first year, every operational mine conducts a self-assessment to evaluate the actual, potential and perceived human rights risks and impacts of the operation. In the second year, an independent human rights assessment program is conducted at mines with medium and high exposure to human rights risks. Due to the review of our human rights policy and procedures in early 2019, we did not carry out any external or third party human rights assessments."
