Should the U.S. prioritize building domestic supply chains for critical industrial minerals and materials?
Greenland Mines has exercised its option to acquire an additional 9.9% stake in AnorTech for approximately US$5.298 million. The move brings the company's total ownership to 19.9% as it seeks to connect Greenlandic resources with North American manufacturing.
Why it matters
This investment supports the development of a North Atlantic Critical Metals Corridor and provides exposure to emerging applications for anorthosite, including sustainable alumina production and lunar construction research.
Greenland Mines acquired 25,168,669 common shares in this transaction, resulting in a total holding of 45,127,172 AnorTech shares. The firm previously shipped 15 tons of anorthosite to Ontario for pilot-plant testing.
The players
Greenland Mines
This resource investment firm is focused on establishing a critical metals supply corridor between Greenland and the United States.
AnorTech
This company owns the Gronne Bjerg anorthosite project and is developing processes for clean alumina production and lunar construction materials.
The details
Greenland Mines satisfied the purchase price by issuing its own common stock to AnorTech, calculated using a 10-day volume-weighted average trading price. AnorTech, which operates the 100% owned Gronne Bjerg anorthosite project, reports that its alumina extraction process avoids the use of bauxite-residue tailings.
Timeline

Roadmap
This transaction follows the pattern set by the development of the North Atlantic Critical Metals Corridor by securing domestic supply chains for high-purity minerals. It reflects a broader industry shift toward internalizing the production of specialized materials essential for modern manufacturing and aerospace applications.
This deal may accelerate the commercial availability of sustainable alumina and advanced lunar simulants for construction and research. Investors and industry participants should monitor pilot-plant results from Ontario for indications of future production scalability.
The takeaway
The increased stake highlights a strategic focus on aligning rare-earth and mineral resource development with long-term technological needs like space-based construction. Companies continue to prioritize sustainable material sourcing as a hedge against traditional supply chain volatility.
