This entry covers about 8 different localities within 50 km of Nuuk, the Capital of Greenland. In these localities Nuummite Nuuk A/S is mining a rock (not a mineral) characterizised by iridescent "orthoamphiboles" (Anthophyllite-Gedrite Series), given the unapproved tradename, Nuummite. This rock is found in more than 3 billion years old Precambrian rocks, in the Malene supracrustals.
