Abstract
EIGHTY years ago William Skey1,2 analysed and described a mineral from Richmond Hill in northwest Nelson, New Zealand, naming it richmondite . His analysis of this material, after deducting 15.4 per cent for siliceous gangue and antimony oxychloride, is as follows : PbS 36.12, Sb2S3 22.20, Cu2S 19.31, FeS 13.59, ZnS 5.87, Ag2S 2.39, MnS 0.52, Bi2S3 traces: total 100. From this analysis Skey calculated the formula Sb2S3.6RS (where R = Pb, Cu, Fe, Ag, Zn), and it was his belief that the mineral, though quite distinct from tetrahedrite, was related thereto.
