Red Hematite.—This occurs in a similar manner as a micaceous 
ore at many points on Digby Neck and at Cape D’Or, frequently 
as brilliant crystalline plates in a quartzose matrix. At some 
points in Hants County it is found in erystals, apparently show- 
ing its derivation from Magnetite. 
Titaniferous Iron Ore—This occurs as a sand on the north 
shore of St. Mary’s Bay, apparently concentrated from the trap 
hills. 
The above ores of iron, although of excellent quality, have 
nowhere been found to exist in quantities which will permit of 
systematic mining. 
Copper.—As already mentioned, this metal is found native at 
Cape D’Or, Parrsboro’, Five Islands and Margaretville, in irregu- 
lar masses up to 50 Ibs. in weight. It presents itself imbedded 
in the trap, or associated with jasper, zeolites, red copper oxide 
and carbonate. Operations have been frequently undertaken in 
the hope of finding deposits suitable for working, but hitherto 
without success. The occurrence of large and valuable deposits 
of copper in the Lake Superior trap has naturally raised expec- 
tations of similar treasures in this Province. The copper which 
appears to be derived from the strata with which the trap is as- 
sociated is not soabundant in the containing measures here as on 
Lake Superior, and both trap and associated strata are of different 
age. 
So long, however, as the copper continues to be found in plates, 
masses, ete., attempts will be renewed to prove their value, 
and it is quite within the possibilities that valuable amounts 
may be found. Any development in this district will pro- 
bably be based on a discovery of large masses or layers of the 
rock containing the copper disseminated in minute grains. At
