Should the U.S. prioritize building domestic supply chains for critical industrial minerals and materials?
Greenland Mines has exercised an option to acquire an additional 9.9% stake in AnorTech, bringing its total ownership to 19.9%. The acquisition, valued at approximately US$5.298 million, was completed through a share exchange.
Why it matters
This move consolidates a partnership aimed at establishing a North Atlantic Critical Metals Corridor connecting raw materials in Greenland to U.S. manufacturing. The company is positioning itself to supply both industrial alumina and specialized materials for lunar simulants.
The transaction involved 25,168,669 common shares priced against a 10-day volume-weighted average of Greenland Mines stock. AnorTech currently holds over C$3 million in working capital as it advances pilot-plant testing of anorthosite, a rock composed predominantly of plagioclase feldspar.
The players
Greenland Mines
An investment firm focused on building a North Atlantic supply chain for critical industrial and technological metals.
AnorTech
A resources company controlling the Gronne Bjerg anorthosite project in Greenland and developing zero-tailings alumina extraction.
The details
AnorTech manages the 100% owned Gronne Bjerg anorthosite project, which reports an average aluminum oxide content of 32%. The company's production process aims to extract alumina—the oxide of aluminum used in industrial smelting—without generating bauxite-residue tailings, which are the alkaline waste products typically left over from traditional alumina refining. To validate this method, AnorTech shipped 15 tons of material to Ontario for pilot-plant testing.
Timeline
June 15, 2026: Parties signed the share exchange agreement.
June 16, 2026: Initial strategic relationship was announced.
June 22, 2026: Initial acquisition of 19,958,503 shares was completed.
October 5, 2026: Greenland Mines announced the exercise of the option.
The Tech Race
This investment reflects an ongoing industry effort to secure alternative sources of alumina outside of traditional bauxite-rich regions. It places the companies in competition with established aluminum suppliers while targeting niche high-purity applications, including research into materials for lunar construction.
The development directly affects the project timeline for producing smelter-grade and high-purity alumina samples. The success of these pilot programs will determine if the material can be scaled to meet demand for both U.S. manufacturing and emerging space-sector lunar simulant requirements.
The takeaway
The firm is scaling its interest in anorthosite as a potential dual-use asset for Earth-based manufacturing and future space-based construction. Investors should track the upcoming results of the Ontario pilot plant to confirm if the alumina production process maintains its zero-tailings claim.
