Environmental and social (E&S) factors are increasingly central to the economic viability of mining projects, influencing expenditures, liabilities, timelines, and access to finance. The demand for critical minerals for the energy transition further amplifies these E&S considerations (World Bank, 2019).
Environmental factors impose significant costs. Land disturbance necessitates reclamation bonds and ongoing rehabilitation expenses, which can be substantial (CostMine, 2024).
Waste rock and tailings management is a major cost centre, with safer alternatives like dry stacking having higher initial CAPEX but potential long-term savings and reduced failure risks (AusIMM, 2023). Air emissions and GHG management require investments in pollution control and decarbonization technologies like CCUS, influenced by carbon pricing (Credence Research, 2024).
Biodiversity impacts lead to costs for assessments, mitigation, and offsets, with financial institutions scrutinizing projects affecting sensitive areas (The Northern Miner, 2025).
Community development agreements and benefit-sharing, though direct costs (e.g., 1-2% of life-of-mine revenue), are strategic investments to mitigate conflict. Anglo American, n.d.). Resettlement Action Plans can be very costly (e.g., US$51 million for Ahafo South RAP).
ESG performance increasingly influences access to capital and financing costs, with sustainability-linked loans emerging. Insurers are also integrating ESG into underwriting, affecting premiums and coverage availability (Finario, 2024).
While universal “green premiums” for responsibly sourced minerals are still developing, strong ESG performance enhances market access. Proactive E&S risk management and investment in sustainable technologies are thus crucial for long-term economic resilience in mining (ERM, 2023).
