J RON. 



The only now locality where this mineral has been found is on Deer 

 Island, near Lord's Cove. The ore is a nearly pure magnetite of 

 superior quality, and occurs in a vein from two to three feet thick in 

 slates and conglomerates of pre-Cambrian age. It is exjx>sed crossing 

 a narrow promontory, and is only a few feet above tide level. 



Copper. 



The principal deposits of copper have been already described in the 

 reports of 1870-71, and nothing has been done of late towards the 

 development of any of the localities therein mentioned. 



Manganese. 



Deposits of this mineral occur at several places in Albert, Kings and 

 Westmorland. They may thus be described :— 



Shepody Mountain. — Deposits near the contact of pre-Cambrian chlo- 

 ritic slates and Lower Carboniferous conglomerates, worked in former 

 years quite -extensively, but of late nothing has been done. 



East Side of Salisbury Bay. — Deposit near the contact of Triassic 

 sandstone and Lower Carboniferous rocks, worked some years ago by 

 the company owning the Markhamville mine, but shortly abandoned. 



Hopewell Comer. — Deposit near the contact of Millstone Grit and 

 Lower Carboniferous ; about one mile west of Hopewell corner. 

 Soon exhausted. 



Hillsdale. — About five miles south-east from Elgin corner. Deposit 

 yet unexplored but fine surface indications. 



Petitcodiac, about two miles north-west from Petitcodiac station. 

 Near the contact of Lower Carboniferous limestone and gypsum, vein 

 only about one inch exposed thickness. 



Jordan Mountain. — Near the contact of Lower Carboniferous sedi- 

 ments with the pre-Cambrian of the mountain. Good surface indica- 

 tions. Locality not developed. 



Markhamville. — Near the contact of Lower Carboniferous limestones 

 and conglomerates with pre-Cambrian. Location long worked. Most 

 extensive deposit as yet known in the Maritime Provinces. 



Quaco Head. — Deposit in Lower Carboniferous rocks. Not yet dev- 

 eloped, but preparations are now being made for mining at this locality. 



Henry's Lake. — Surface indications reported, but deposit not located.
