266 MINERALS FOR THE PARIS EXHIBITION. GILPIN. 



In Cape Breton as yet there has been little iron ore 

 development. An extensive and valuable deposit at Gillis Lake, 

 is known as the Moseley mine. 



The following set of analyses will tend to show its quality : 

 1. 2. 3. 4. 



Iron C3.45 63.20 58.90 64.10 



Silica 6.96 6.42 13.38 4.71 



Phosphorus 0212 .014 .0257 nil. 



Sulphur 0631 .0604 .0041 .0027 



The bed, which has been traced for several miles, averages 

 about seven feet in thickness, and is associated with a crystalline 

 limestone, presumably of laurentian age. It is within about 

 four miles of deep water, and about eight miles from the 

 Intercolonial Railway. 



In the devonian strata in the neighborhood of St. Peter's, 

 Richmond County, there are a number of deposits of specular 

 ore, similar to those found in strata of the same age in Guysboro 

 County. 



The following analysis from the Micmac mine, about six 

 miles from St. Peter's, will serve to show the class of this ore: 



Iron 68.18 Sulphur 15 



Silica 2.48 | Phosphorus 05 



Prospecting work at Whycocomagh, Cape Breton, has shown 

 the presence of a number of beds of magnetite and red hematite 

 up to twelve feet in thickness. Judging from surface indications, 

 there is an extensive iron field in this locality. Analyses show 

 metallic iron, from 49.13 to 63.20 ; Silica, up to 21.90 ; Sulphur, 

 trace to .55 ; Phosphorus, trace to .49. 



Very extensive deposits of a similar character occur at 

 Nictaux, Annapolis Co., and are represented by a number of 

 samples. A deposit of red hematite, at Torbrook, in this 

 district, about six feet thick, was worked for some years, until 

 the Londonderry Furnaces were closed. A description of the 

 ores and analyses will be found in a paper on the Iron Ores of 

 Nictaux read by me before this Institute a few years ago.
