Vokes (1963) states a possible occurence of arsenic as small patches intergrown with gudmundite, pyrrhotite and chalcopyrite. According to Cook et al. (1998), the occurrence of native arsenic was confirmed by Moralev et al. in Open Reports Nor. Geol. Unders. 95.154, 120 pp. (1995) and Nor. Geol. Unders. 96.155, 33 pp. (1997).
