First Action Plan for the sustainable management of mineral raw materials 2026–2030 (PAMPM), incl. National Mining Exploration Programme
Approved by the Council of Ministers with EUR 414 million in linked public investment and 34 interdepartmental regulatory, sectoral, cross-cutting and R&D measures. Its four axes are autonomy, industry promotion, circularity and sustainable management. It includes Spain's first National Mining Exploration Programme in 50 years (EUR 182 million), with a line for recovering materials from tailings and mine-waste deposits.

Law 7/2021 on Climate Change and Energy Transition, Article 10: no new permits for radioactive minerals
From the law's entry into force, Spain no longer accepts applications for new exploration or research permits or direct mining concessions, or their extensions, for radioactive minerals extracted for their radioactive, fissile or fertile properties. Applications for new nuclear-fuel-cycle facilities to process such minerals are also no longer accepted.

Fiscal regime for mining
| Instrument | Applies to | Rate | Legal basis |
|---|---|---|---|
| Corporate income tax (mining) | All mineralsGeneral corporate tax rate 25% (entities with net turnover below EUR 1 million: 17% on the first EUR 50,000 and 20% above; new entities 15% for two years). No mining-specific rate, but miners operating under the Ley de Minas (Sections C and D resources) may reduce the tax base by a depletion factor (factor de agotamiento) of up to 30% of the mining tax base, or, for minerals declared priority under RD 647/2002, up to 15% of the value of minerals sold, amounts to be reinvested in listed mining activities (Arts. 91-95) | 25%base imponible (taxable income) | Ley 27/2014, de 27 de noviembre, del Impuesto sobre Sociedades · Art. 29.1; Arts. 91-95in force 2025-01-01 |
