Breithauptite : NiSb

Co-Ni arsenides on copper-colored breithauptite, field of view 6 mm. From the Beaver-Timiskaming Mine near Cobalt, via Fender Natural Resources (2007). The specimen was labeled silver on breithauptite, but it appears to be breithauptite overlain by skutterudite and other arsenides (see also child photo). Thanks to Reiner Milke for help with the correct identification.
