From which it will be seen that though rather asilicious ore, 
it is low in sulphur and phosphorus, and high in metallic iron. 
The vein dips at an angle of about 80° to the south at the 
surface, and flattens to 45° at a depth of 350 feet (as proved by 
the workings of the ‘Torbrook Iron Co.), and the general strike 
throughout the district is about N. 62 E. 
This company in 1896 completed their contracts, and no 
immediate market offering elsewhere, they closed their mine, 
after having shfpped in the five years 135,000 tons of ore to the 
Londonderry and Ferrona furnaces. When closed down, the 
mine showed large quantities of good ore in sight, and a vein 
from 6 ft. to 12 ft. in thickness. 
About 65 feet to the south of this vein lies another deposit of 
red hematite, called from its fossiliferous character the “Shell 
ore vein,” which from several analyses runs about 54/ metallic 
iron. This vein measures about 6 to 9 feet in width. The 
fossil shells occuring in this bed consist of varieties of Spirifer, 
Strophomena, Atrypa, Avicula, Bellerophon, ete., ete. 
North of the vein worked by the above company, and about 
a mile west of their mines, another vein five feet in width has 
been found, which at this point presents in common with most of 
the iron deposits in the district, different characteristics, as it is. 
*These analyses are from a paper on the Iron Ores of Nictaux, by Dr. E. 
Gilpin, Nova Scotian Institute Science—session 1894-95.
