These analyses show that there are ores in this vicinity 

 valuable enough for shipment as regards quality, and the present 

 owners consider that new explorations now being carried on 

 will show that the ore is present in quantities sufficient to war-

In this connection reference may be made to this division of 

 the Cape Breton Laurentian in which these deposits occur. It
