White Mountain Anorthosite Project

An operating mine producing green products

The White Mountain (Qaqortorsuaq) anorthosite (calcium feldspar) mine in Greenland brings green products to the world. The refined products, GreenSpar and Anocrete, bring significant green benefits and cost savings to our customers. The White Mountain mine will have multiple revenue streams as the products have applications in the fiberglass, alumina, filler, paint and white cement markets.

The mine adheres to the strictest environmental standards and does not use any chemicals or water for processing.  The mine is permitted for 50 years and has a current mine life of over 100 years with the deposit being open in all directions. Hudson has a 10 year supply agreement with one of the world leaders in E-Glass fiberglass production.

What is Anorthosite?


Hudson’s anorthosite is a calcium feldspar rock which is primarily comprised of aluminum (31%), silicon  (50%) and calcium (15%).  The White Mountain anorthsoite is unique in its size and purity.

Typically, calcium-rich anorthosite deposits are small, irregular and contain too many impurities for commercial applications.  The White Mountain ore body is geologically massive and homogeneous with no competitors. The only larger anorthosite occurance is on the moon, which is 384,000 km away.

Project Highlights


  • Hudson has a 33% interest in the project.
  • Fully permitted mining project for 50 years.
  • Over 100 years mine life based on current drilling.
  • Unique deposit with no significant competitors.
  • 10 year supply agreement with world’s premier fibergalss producer.
  • Four potential revenue streams from one mine.
  • Low capial cost to build mine ($40M, plus $10M in indirects, reclamation, working capital).
  • Simple mine processing translates to low operating costs and attractive margins.
  • Excellent infrastructure with fully operational deep water port.
  • International airport 80km from the project.
  • Production expected in the second half of 2018.

Multiple Revenue Streams


A replacement for kaolin in the production of E-glass fiberglass. A 10 year off-take agreement has been signed with a leading fiberglass producer.

Paint & Polymer Fillers

A replacement for kaolin and nepheline syenite in paints, coatings and polymers.

Source of Alumina

A replacement for bauxite as a primary source of alumina without producing any waste or tailings.


A replacement for Portland cement to produce Anocrete, a CO2 free white cement.
