It occurs as microscopic inclusions within massive chalcopyrite at Temagami in assotiation with other rare tellurides: merenskyite, stützite, hessite and an unnamed Pd-Hg-Ag telluride.^[4] In addition to the discovery locality, it has been reported from the Stillwater igneous complex in Montana and the New Rambler Cu–Ni mine in the Medicine Bow Mountains of Wyoming.^[2]
