252 SOME ANALYSES OF NOVA SCOTIA COALS 



In the upper part of George's River in Cape Breton County 

 there is a large deposit of iron pyrites in rocks which are, I 

 think, laid down as Laurentian by the Geological Survey. The 

 deposit has as yet been examined only superficially, but so far 

 appears somewhat low in sulphur. The following analysis of 

 samples from the most promising exposure gives : 



Sulphur 25-00 



Copper 1-10 



Gold Trace. 



Silver Trace. 



Silica 52-00 



Iron, etc 25'00 



For a number of years the presence of iron ore at Whycog- 

 omah in Cape Breton has been well known. The ores which are 

 magnetites and red hematites are so very favourably situated, 

 being close to the waters of the Bras d'Or Lake, that a good 

 deal of work was done on them a number of years ago. A 

 number of beds were opened and traced. They varied up to 

 nine feet in thickness, and occurred in the Limestone division of 

 the Laurentian, as described by Mr. Fletcher in his numerous 

 reports on the Geology of Cape Breton, issued by the Survey. 



The analyses of the ores were contradictory in character, 

 some being high in phosphorus, while others were very pure and 

 ran high in iron. Last fall fresh discoveries were made in this 

 district some distance from the old openings, of beds of magnetite 

 some upwards of 100 feet in width. Indications are not want- 

 ing that these ores extend over a large tract of country. 



The following analyses will serve to show the quality of 

 the ores : 



Silica 14-41 



Alumina 7'33 



Manganese Oxide '61 



Lime 3'00 



Sulphur -22 



Metallic Iron ,.... 54'50 



Phosphorus Trace. 



Magnesia Trace.
