The European Union has made major progress in building its critical raw materials strategy, establishing strategic projects, domestic supply targets and new financing mechanisms. Yet a fundamental weakness remains: Europe does not have enough new mineral discoveries capable of becoming future mines.
A technical assessment prepared by the European Investment Bank and Aurum Exploration estimates that EU mineral exploration spending is currently around €200 million a year. Rebuilding a pipeline capable of supporting the bloc’s critical-minerals ambitions could require approximately €2 billion annually for five years, or around €10 billion in total. That would represent a tenfold increase and put European exploration spending above recent levels in Canada, Australia and the United States. The challenge is particularly significant because Europe is rebuilding an exploration industry after years of relatively limited investment.
The problem starts well before mine financing. A deposit must first be discovered, drilled, modelled and tested before it can become a resource, secure permits and attract development capital.
Exploration is also highly speculative. Only a small fraction of grassroots projects progress to discovery, and an even smaller proportion ultimately reaches commercial production. The entire journey from initial exploration to an operating mine can take seven to 20 years. This creates a major timing problem for the EU’s Critical Raw Materials Act. The bloc wants domestic extraction to supply 10% of annual strategic raw-material consumption by 2030, but exploration spending made between 2026 and 2030 will largely influence mine production during the 2030s and 2040s. Near-term supply must therefore come from deposits that have already been discovered, brownfield expansions, mine restarts and advanced projects.
Europe Needs More Active Exploration
The decline in European mineral exploration is already visible. Between 2005 and 2014, 16 mines based on grassroots discoveries entered production in the EU. During 2015-2024, that number dropped to just four. In 2024, only around 31 exploration targets were being drilled across the EU. The EIB assessment suggests that achieving the scale implied by European critical-minerals policy could require roughly 220 to 440 active drilling projects.
Europe’s share of global exploration spending has remained around 2-4% since the late 1990s. In 2024, Canada attracted about 20% of global exploration expenditure and Australia around 16%, while the EU accounted for only about 3%.Several European countries demonstrate that exploration can succeed under strict environmental and regulatory standards.
Finland, Sweden and Ireland have comparatively strong geological databases, mining expertise and established exploration industries. Portugal and Bulgaria also retain significant mineral potential. Finland and Sweden are particularly important for copper, nickel, lithium, gold and battery minerals, while Ireland has a long history of base-metal exploration.
The Balkans Could Become More Important
Southeastern Europe could play a larger role in the continent’s future mineral supply. The Tethyan metallogenic belt extends through the Balkans and Central Europe and contains important copper, gold and polymetallic systems. Serbia, Bulgaria, North Macedonia, Bosnia and Herzegovina and Montenegro all possess geological potential, although exploration intensity varies considerably. The region could contribute to European supply chains for copper, gold, lead, zinc and other critical minerals.
Yet investors face familiar obstacles, including uncertain permitting, incomplete geological databases, limited early-stage financing, land-access issues and community opposition. For the Western Balkans, the challenge is not simply discovering more deposits. Projects must demonstrate that they can satisfy European environmental, technical and financing requirements while delivering visible benefits to local economies.
Exploration Needs Equity, Not Traditional Debt
One of Europe’s biggest problems is the mismatch between exploration risk and conventional financing. Early-stage exploration can require hundreds of thousands of euros annually, with spending increasing substantially once a discovery enters resource-definition drilling. Most projects ultimately fail, meaning there is no predictable cash flow to service traditional bank debt.
Junior exploration companies therefore need risk capital, tax incentives, grants, royalty structures, convertible financing and staged investment. Debt becomes more appropriate once a resource has been established and technical and economic risks have been reduced. The EIB Group has committed to deploying significant capital across critical raw-material extraction, processing and recycling, but upstream exploration remains difficult to finance through conventional development-bank products.
Canada Offers a Possible Model
Canada provides an example of how government policy can stimulate exploration. Its flow-through share system allows qualifying exploration expenditures to be passed through to investors for tax purposes. Certain critical-mineral investments can also qualify for a 30% federal tax credit. This system operates alongside a large listed mining sector, extensive geological databases, exploration incentives and public geoscience programmes.
Australia follows a similar approach, combining exploration incentives with government-funded geophysical surveys and pre-competitive geological information. Europe already possesses many of the institutions required to develop a comparable ecosystem, including national geological surveys, EuroGeoSurveys and European geological-data platforms. The weakness is that geological information and technical capacity remain uneven across member states.
A European Exploration Fund Could Fill the Gap
One proposed solution is a dedicated EU-wide exploration facility capable of providing roughly €300 million to €500 million annually. If public funding could attract three to five times as much private capital, such a mechanism could mobilise a significant portion of the estimated €2 billion annual exploration requirement.
The structure would need to operate more like a specialist natural-resources investment fund than a conventional lending programme.
Capital could be released through exploration milestones covering:
- Target generation
- Geophysical surveys
- Initial drilling
- Discovery confirmation
- Resource definition
- Metallurgical testing
- Preliminary and feasibility studies
Projects that fail would be stopped quickly, while successful discoveries could receive additional funding or be transferred to larger mining companies.
Strategic Exploration Zones Could Accelerate Discovery
The EIB assessment highlights established European mineral belts including the Iberian Pyrite Belt, Fennoscandian Shield, Tethyan Arc, Kupferschiefer Belt, Variscan Belt and Alpine metallogenic belt. Concentrating geological surveys, exploration incentives, infrastructure planning and permitting resources in these regions could improve the probability of finding economically significant deposits. This would not mean reducing environmental standards. Instead, Europe could establish clearer administrative procedures and proportionate requirements for early-stage exploration.
Permitting delays are particularly damaging because exploration companies operate within highly cyclical commodity markets. If obtaining an exploration licence takes several years, a company can lose an entire investment cycle before drilling even begins.
Technology Can Improve Targeting
New technologies could also make European exploration more efficient. Satellite imaging, hyperspectral surveys, artificial intelligence, automated core analysis and 3D geological modelling can process large amounts of information and identify promising targets more efficiently. They cannot eliminate drilling or geological uncertainty, but they can reduce the number of expensive targets that need to be tested.
Europe’s extensive historical mining record also creates opportunities to reassess old districts using modern exploration techniques. Mine waste and historic tailings could provide another source of copper, gold, silver, zinc and critical minerals. Modern sorting and hydrometallurgical technologies may make previously uneconomic material recoverable, while potentially supporting environmental remediation.
Exploration Is the Missing Link in Europe’s Mineral Strategy
Europe has developed much of the policy framework needed to strengthen its critical raw materials supply chain, but policy alone cannot create mines. The estimated €10 billion exploration requirement should be viewed as a long-term pipeline-building programme rather than a quick solution to the EU’s 2030 supply targets. Existing projects and brownfield developments will determine much of Europe’s mineral supply over the remainder of this decade. The exploration decisions made now will shape the continent’s mining industry throughout the 2030s and early 2040s.
The central challenge is therefore not simply finding more money for mining. Europe needs to build a complete financing and technical ecosystem that can take a mineral target from geological discovery to resource definition, permitting, feasibility, construction and processing. Without that upstream pipeline, Europe’s strategic-minerals ambitions risk producing more policy targets than actual mines.
