As part of our environmental management commitment at PT-FI, external audits of PT-FI’s Grasberg operations have taken place on a routine basis since 1996. The current audit is PT-FI’s ninth triennial audit and was carried out by PT LAPI ITB, a unit under the Bandung Institute of Technology (ITB). While this audit was originally due to be completed in 2020, it was delayed due to the COVID-19 pandemic and was completed in early 2023. This audit included in-person site visits in 2022 to evaluate PT-FI’s compliance with national environmental laws, environmental-related government regulations, environmental standards and a review of tailings management, the Grasberg open pit closure, among other key environmental topics. The field portion of the audit was conducted in May and June of 2022.
