The IRON HOLM OAK PILOT is a pioneering industrial mining project focused on the sustainable recovery of critical raw materials. Led by consortium partners Gevora and Leonore, the project aims to unlock the potential of endogenous mineral resources using advanced technologies and innovative circular processes. With a strong commitment to environmental protection, social responsibility, and economic viability, the IRON HOLM OAK PILOT sets a new benchmark for sustainable mining in Europe.
Demonstrating Combined Circular Processing for Rare Earth and Iron Ore
Explore how the IHO pilot project is reshaping the future of raw material supply in Europe. Through innovative processing technologies and a strong commitment to circularity, this pilot demonstrates a practical and scalable solution to recover both iron ore and rare earth elements (REEs) from previously untapped or underutilised resources. At its core, the IHO pilot proves that sustainable mining isn’t just possible — it’s profitable and replicable.
Highlights of the IHO Pilot Achievements
High-Grade Iron Ore Production
Delivered an impressive 71% Fe iron ore concentrate in pellet feed format – essential for the rise of green steel manufacturing across Europe.
Rare Earth Element (REE) Recovery from Waste
Successfully extracted REE concentrates (17,000 PPM TREO) from tailings, showcasing a breakthrough in sustainable resource recovery.
Integrated Technological Solutions
Developed a fully synchronised process plant that enables simultaneous iron ore production and REE separation, minimising waste and maximising efficiency.
Environmental Sustainability and Innovation
One of the most notable achievements of the IHO pilot lies in its comprehensive environmental strategy. A closed-loop water cycle was developed to reduce water consumption drastically, ensuring minimal ecological disruption during operations. This system, combined with the integration of renewable energy, advanced process automation, and improved logistics, significantly lowers the project’s overall carbon footprint — aligning it with Europe’s low-carbon transition goals.
Furthermore, the project applies a circular approach to tailings, reusing waste materials in innovative ways. Not only are additional minerals recovered from these tailings, but they are also being repurposed for use in construction and cement production. This holistic resource efficiency strategy supports a new standard for environmental responsibility in the mining sector.
Socio-Economic Value and Regional Impact
The IHO pilot is as much about people as it is about technology. By reactivating dormant mining operations in economically challenged regions, the project is generating local employment and stimulating regional development. Its collaborative ecosystem — involving technology providers, universities, SMEs, and regional governments — ensures that the value created stays within the communities involved.
A particular emphasis has been placed on social inclusion, with an actionable plan to promote the integration of women in mining, traditionally an underrepresented sector. Additionally, a dedicated social reinvestment fund has been established, channelled directly from mineral sales, to support ongoing community needs in areas affected by mining activity. This social commitment underpins the project’s broader goal: creating long-term, inclusive growth that extends beyond the mine.
Strategic Partnerships and Collaboration
Behind the IHO pilot is a broad and dynamic network of collaborators spanning industry, academia, government, and SMEs. From mining operators and logistics providers to research institutions and regional development agencies, this project has thrived through collective intelligence and shared purpose. Open calls have encouraged SME involvement, allowing innovative solutions to emerge from a diverse range of contributors — many of whom have transitioned into long-term suppliers.
This open and inclusive approach not only strengthens the pilot’s outcomes but also enhances its replicability across Europe, reinforcing the EU’s strategic autonomy in critical raw materials.
The Road Ahead – Scaling Up and Commercialising
Following the success of the pilot phase, the next steps are focused on scaling to full industrial operation. Licensing procedures are being finalised, financing rounds are underway, and plans for the construction of a commercial production facility are in motion. The long-term vision includes not only the production of iron ore and REE concentrates but also the conversion of REE oxides into marketable carbonates and the development of new value chains around pyrite and other critical raw materials such as copper, nickel, and cobalt.
By continuing to innovate and expand, the IHO initiative aims to set a precedent for sustainable, circular mining in Europe — one that delivers economic value while respecting both people and the planet.
