Cu31S16
Monoclinic
Djurleite, a copper sulfide mineral, was first reported from Franklin by Cook (1973). It was found associated with dolomite and hematite in a vein in franklinite-willemite ore. No other data were given. Djurleite was reported from Sterling Hill by Jenkins and Misiur (1994).
The writer has found djurleite on specimens labeled chalcocite; these two grayish-black, opaque, sectile minerals are visually identical and require X-ray techniques for identification. Like chalcocite, djurleite may have a sooty surface coating. Djurleite is far less abundant locally than chalcocite.
