254 SOME ANALYSES OF NOVA SCOTIA COALS, ETC.—GILPIN. 
of excellent quality, and dolomites, suitable, as at New Camp- 
bellton, for furnace linings. Iron ores occur in them at numerous 
points both hematite and magnetite. Graphite is also found 
In all probability, phosphates, similar to those found in Quebec 
will be proved on search being made. Where these measures 
are cut by dykes, copper and lead ores carrying gold and 
silver occur, and may in some cases prove valuable. As yet so 
far as my information goes free gold has not been found in 
quartz in the limestone division. The gold of Middle River and 
Cheticamp appears to be associated with soft taicose and felsitic 
schists of the other division. This gold oceurs at Middle River 
free in quartz, and in the river gravel, derived presumably both 
from the quartz and augmented by gold flakes from the schists, 
At the Cheticamp River, so far as can be judged from the work 
done, it would appear to have a similar source, and to be con- 
nected only with the felsite series. In the latter case part of 
the gold may be derived from mineralized zones adjoining the 
dykes cutting the various rocks. However, the explorations of 
the coming season will probably give us more exact information. 
It is interesting to note in connection with the oecurrence of 
gold at Cheticamp that native silver occurs in the Mackenzie 
River a short distance north, and it is possible that explorations 
in that section may result in the discovery of important amounts 
of this metal and associated gold.
