Snapshot	The White Mountain Project is Greenland’s only active anorthosite mine, producing a mineral rich in aluminum with a wide range of industrial applications. The Project is owned by a majority privately held business and involves the shipment of anorthosite from a processing plant in Greenland to customers across three continents. Mine production figures have not been publicly disclosed since 2021. White Mountain anorthosite is marketed under the tradename Greenspar™ and is used as a component in e-glass, mineral wool, paints, and plastics. The anorthosite operation at Qaqortorsuaq recently completed its largest shipment to date, with 30,031 tonnes of anorthosite dispatched to customers worldwide. This shipment confirms the operational scale achieved and reflects continued market demand for anorthosite in applications related to the green transition.

Summary:

Metamorphosed calcic anorthosites form one of the most distinctive rock units in the Archean gneiss complex of West Greenland. These anorthosites are of special interest because of their unusual composition with extremely calcic plagioclase, low-levels of extraneous mineral contaminates, and extensive preservation of primary igneous textures and minerals. These unique mineral-chemical attributes are directly linked to their potential use in various industrial mineral applications, in particular, their use as an alternative source of raw material for the aluminum industry.

Mineralization on the property consists of anorthosite with minor muscovite (2%) and clinozoisite (3%). Rutile, pyrite and biotite are present in extremely small amounts («1%) Thin section petrographic analysis (Le Couteur, 2012) indicates the anorthosite is composed of approximately 95% plagioclase. The rock is hard, massive and has an off-white colour with some vaguely defined patches having a faint brownish cast. The plagioclase varies in grain size up to about 30 mm across. The brownish-tinged patches appear to be large single crystals. The rock is described as coherent but crazed with fine fractures radiating in all directions, indicating the impact of tecto-morphism activity. Pale yellow clinozoisite grains up to 8 mm across, but typically less than 2 mm, account for about 2% of the rock mass. The clinozoisite grains are scattered throughout the rock mass, with some strung along fractures or present a fine veinlets. Pale-yellowish silvery muscovite up to 10 mm across is present at about 2% of the rock mass. Small (<0.1 mm) re-brown biotite plates can be observed in the coarsest transparent plagioclase.
