The deposits are copper-free, for the most part, lenticular in outline and conform in a general way with thestrike and dip of the surrounding rocks. Much of the pyrites is rich enough to shipdirectly without concentrating. It is also largely free from impurities which are objec-tionable in the manufacture of sulphuric acid. The mineral ranges from heavy densematerial, containing about 50 per cent, of sulphur, to silicious pyrites containing about35 per cent. After describing the deposits in more detail, the genesi- of the pyrites will be considered. 96 Bureau of Alines No. 4 Shaft \ :nz~ fao^Leve / (A Five 4K—Part of underground workings, Canadian Sulphur Ore Compan> .
