During our search for PGE minerals, in a basalt sample from the drillhole Rm 135, 543.6 m cobaltite (CoAsS) was found by ore microscopic and microprobe analyses. Until now, this mineral has not been mentioned in this area. The cobaltite forms tiny, 5-10 µm large, angular crystals in another ore mineral, the chalcopyrite (CuFeS2). At the moment, the cobaltite is still a curiosity, significant cobalt enrichment is not known.
