Mining Fiscal Regimes Under Pressure: Royalties, Windfall Taxes, and the New Government Take

Sustained commodity price strength since 2023 has prompted at least a dozen jurisdictions to restructure their fiscal take from mining, through sliding-scale royalties, margin-based windfall taxes, and expanded state-equity demands. Chile's 2024 mining royalty act lifted the effective burden on major copper operations toward the mid-40s percent, with a statutory cap above that. Ghana moved on a sliding-scale gold royalty in late 2025 with spot prices already through multi-year highs, and the Philippines enacted a tiered windfall tax on metallic mining. The report quantifies the project-level economics of these measures, maps the spread of free-carry and state-equity provisions, and assesses how the OECD global minimum tax interacts with the exploration incentives many jurisdictions still maintain.
