The copper region commences at Choc.

the Southern shore Of that Lake some 350
miles 10 the British line, pursuing North

ore appears in veins on the surface Of the
earth and in rocks on the hill sides. These
veins vary in width from 6 to l6fee,.-
Some of them descend into the earth per-

inclination, and some Of them, after per-

The cost of getting ore to the surface

Operations were commenced b, two
companies in lS44. In IS45 Twelve
more companies have begun working.
The location Of the companies are gen.

The two companies which commenced
