Greenland Mines increases its AnorTech stake to strengthen industrial and lunar supply ties.

Greenland Mines has exercised its option to acquire an additional 9.9% of AnorTech, bringing its stake to about 19.9% and completing the second tranche of a strategic relationship announced in June. The transaction is to be paid for with newly issued Greenland Mines shares, with completion subject to required exchange acceptance. The companies say the investment strengthens their ties around AnorTech’s Gronne Bjerg anorthosite project in Greenland, which they see as a potential source of material for alumina and other industrial products. They also point to anorthosite’s potential in lunar research: the rock resembles material found in the Moon’s highlands and can be used in lunar soil simulants and research on construction materials, including 3D-printed structures.
Greenland Mines says the Gronne Bjerg project is about 80 kilometers from Nuuk and has open-tidewater access, which it presents as an advantage for supplying industrial materials.
Greenland Mines cited U.S. Geological Survey data that net imports met an estimated 71% of U.S. alumina consumption in 2025, framing Gronne Bjerg as a potential feedstock source for U.S. smelter-grade and high-purity alumina production.
AnorTech says it has already supplied its anorthosite to space-sector researchers for use as a lunar simulant, rather than the lunar-research application being only a prospective use.
In the share exchange, AnorTech is also due to receive Greenland Mines shares, giving it a position in a Nasdaq-listed company; the number of shares will be calculated using Greenland Mines’ 10-day volume-weighted average price immediately before closing.
