To measure the impact of community engagement efforts, the Company uses the Social Return on Investment (SROI) framework, evaluating 12 community development programs across 4 mine sites in Indonesia. In addition, a “Maturity Measurement” approach is applied to assess the sustainability of these programs across 6 dimensions: change, inclusion, organization, cooperation, influence, and sustainability. As of 2024, this comprehensive assessment has been implemented at 80% of the mines in Indonesia.
