Europe has built a broad policy framework for critical raw materials, but its mineral project pipeline remains constrained by a shortage of new discoveries. A technical assessment by the European Investment Bank (EIB) and Aurum Exploration estimates that annual EU mineral exploration spending would need to rise from about €200 million to €2 billion for five years, creating a cumulative requirement of approximately €10 billion.
That would put European exploration spending above recent levels in Canada at about €1.5 billion, Australia at €1.3 billion and the United States at €900 million. The assessment links the gap to decades of underinvestment, fragmented regulation and reduced institutional capacity. The funding requirement reflects the long development cycle of mining. Grassroots exploration has an estimated success rate of only one project in 10,000, while about one in 1,000 discoveries progresses towards an operating mine. Even resource-definition projects may have only about a one-in-100 chance of ultimately reaching production.
Exploration timelines limit the impact of current spending
Mineral exploration generally requires three to nine years, followed by another three to eight years for scoping, pre-feasibility and feasibility work. Financing and construction can add a further one to four years, producing an overall exploration-to-production timeline of approximately seven to 20 years. This creates a significant timing issue for the EU’s Critical Raw Materials Act. Its objective is to obtain 10% of strategic raw-material demand from domestic extraction by 2030, but exploration spending made between 2026 and 2030 will largely influence mine supply during the 2030s and early 2040s.
The EIB assessment identifies a need for at least 22 new or reopened mines, particularly for critical raw materials where European extraction remains below the relevant benchmark. Newly discovered grassroots deposits cannot generally be converted into operating mines by 2030, leaving advanced projects, brownfield expansions, dormant mines and historic districts as the principal sources of near-term supply.
Europe’s exploration record reflects the weakness of the pipeline. Sixteen mines based on grassroots discoveries entered production across the EU between 2005 and 2014, compared with only four between 2015 and 2024. Including discoveries, restarts and brownfield developments, the number fell from 23 projects to 13.
Exploration remains concentrated in a few European jurisdictions
The EU has maintained only 2–4% of global exploration spending since the late 1990s. In 2024, Canada accounted for about 20% of global exploration expenditure and Australia 16%, while the EU received approximately 3%, equivalent to about $360 million under the study’s methodology. Per-capita spending shows an even wider disparity. From 1997 to 2024, annual exploration expenditure averaged $45.46 per person in Australia, $35.56 in Canada and only $0.50 in the EU. During 2019–2024, the figures increased to $68.83, $49.51 and $0.68, respectively.
Finland, Sweden and Ireland stand out within Europe. Between 2019 and 2024, Finland recorded about $281 per square kilometre in exploration spending and Sweden $220, compared with $245 in Australia and $226 in Canada. Ireland recorded approximately $173 per square kilometre. These jurisdictions benefit from favourable geology, functioning geological surveys, established licensing systems, accessible historical information and greater community familiarity with mining. Portugal and Bulgaria display some of these characteristics, although investment has been less consistent.
The overall EU exploration base remains small. In 2024, only 31 exploration targets were being drilled across the Union. The EIB estimates that achieving the scale implied by the CRMA could require between 220 and 440 active drilling projects. Sweden, Finland, Spain and Ireland accounted for roughly 88% of EU exploration metres, leaving most other member states with limited advanced exploration.
Tethyan and Balkan mineral belts remain underexplored
The Tethyan metallogenic belt, extending through the Balkans into Central Europe, contains major copper, gold and polymetallic systems. Bulgaria maintains an established exploration and mining sector, while other sections of the belt remain unevenly mapped, inconsistently licensed or reliant on historical datasets. The Western Balkans sit outside the EU institutional framework but share its geological and industrial environment. Serbia’s copper and gold sector, Bosnia and Herzegovina’s base-metal potential, North Macedonia’s polymetallic districts and Montenegro’s historic lead-zinc areas could contribute to European supply chains.
Projects across the region face challenges involving permitting, geological-data integration, community opposition, early-stage financing and the ability to meet European environmental, technical and financial requirements. Grassroots exploration typically requires only €50,000–€150,000 per project annually, rising to €400,000–€600,000 during discovery and reaching €1.1 million–€15 million annually during resource definition. Although these sums are small compared with mine construction, most exploration projects fail and generate no operating cash flow.
EIB and EBRD programmes target the early financing gap
The EIB says its conventional lending products are poorly suited to speculative exploration. Junior explorers instead require risk equity, tax incentives, grants, royalties, convertible instruments and milestone-based funding, with debt becoming more appropriate after resources and technical studies reduce project uncertainty. In March 2025, the EIB Group committed to deploying €2 billion annually across critical-mineral extraction, processing and recycling. Upstream exploration has not received comparable financing because its risk profile does not fit standard lending structures.
The EBRD Junior Mining Programme (JUMP) provides one existing model. Its €150 million framework supports equity and quasi-equity investment in early-stage mining companies but covers only 12 EU member states, representing about 27% of EU territory. Another 15 members remain outside the programme. The proposed EU-wide facility would require approximately €300 million–€500 million annually. Assuming public capital could mobilise private funding at ratios between one-to-three and one-to-five, the mechanism could contribute significantly toward the estimated €2 billion annual exploration requirement. Funding would be released through stages covering target generation, geophysics, initial drilling, discovery confirmation, resource definition and technical studies. Portfolio diversification across commodities, geological regions and jurisdictions would be required because individual-project failure is normal in exploration.
Canada and Australia provide established exploration models
Canada’s exploration financing system provides a contrasting model. Its flow-through share mechanism allows qualifying exploration costs to be transferred to investors for tax deduction, while specified critical minerals can qualify for a 30% federal tax credit. Flow-through financing represents approximately 65–70% of capital raised on Canadian exchanges by exploration companies. The system operates alongside more than 1,200 mining companies listed on the Toronto Stock Exchange and TSX Venture Exchange, provincial exploration incentives, digital claim-staking systems, open geological databases and government-funded geophysical programmes.
Australia combines junior exploration incentives with public support for greenfield drilling and pre-competitive geoscience. Government-funded magnetic, gravity, seismic and hyperspectral surveys provide information that multiple exploration companies can use before committing private drilling capital.
Europe already possesses parts of this institutional infrastructure through national geological surveys, EuroGeoSurveys and the European Geological Data Infrastructure. However, national survey capacity varies, with some organisations absorbed into broader government departments and facing declining budgets and specialist staffing. Geological maps can be outdated, while historical drilling data is not consistently digitised. Under Article 19 of the Critical Raw Materials Act, EU member states were required to prepare national general-exploration programmes by 24 May 2025. These programmes cover mineral mapping, geochemical campaigns, geoscientific surveys, predictive modelling and the reprocessing of historical information.
Strategic exploration zones and historical mine waste
The EIB recommends concentrating early exploration efforts on established mineral systems such as the Iberian Pyrite Belt, Fennoscandian Shield, Tethyan Arc, Kupferschiefer Belt, Variscan Belt and Alpine metallogenic belt. Strategic exploration zones could combine public geoscience, permitting resources, infrastructure planning and financial incentives around areas with established mineral potential. Environmental assessment would remain necessary, while early community engagement would be important because exploration can become a visible source of local opposition before technical or economic viability has been established.
The assessment indicates that permitting remains a major constraint. Exploration licences can require two to seven years in parts of Europe, compared with approximately one to two years in leading jurisdictions. Long approval periods can consume much of a commodity-price cycle before drilling begins. Technology can improve exploration efficiency without eliminating geological uncertainty. Satellite remote sensing, hyperspectral imaging, artificial intelligence and 3D or 4D subsurface modelling can process larger datasets and improve target selection.
Historic mine waste provides another potential source of critical minerals. Old tailings and waste-rock deposits may contain materials that were not recovered during original operations. Modern mineral processing, sensor sorting, hydrometallurgy and recovery technologies could convert some of these materials into secondary resources while contributing to remediation. Such projects still require resource classification, metallurgical testing and economic evaluation, particularly where grades are low, mineralogy is complex or historical environmental liabilities remain unclear. The EIB assessment puts the immediate exploration requirement at approximately €10 billion over five years, while the broader challenge extends across the entire mining development chain, from geological data and speculative drilling to resource definition, feasibility studies, permitting, construction and processing.
