To quickly assess the difficulty of the text, read a short excerpt:
In the district of Chuquicamata, which is in the volcanic Cordilleras, 160 miles from Antofagasta by the railway and 9,000 feet above sea-level, are half a dozen copper mines producing 18,000 to 20,000 tons of ore which averages 1 8 per cent. The area is 8 square miles of country rock of pure granite with true fissure lodes, and it is estimated that there are 15,000,000 tons of decomposed rock averaging one- half of I per cent of copper. In the Capopo district are a group of copper mines which ...have a monthly output of 2,500 or 2,600 tons of ore, the sulphides predominating in most of them.
The copper industry of Chile has been a reason- ably profitable and steady one, and without doubt it is capable of a considerable expansion by the application of modern methods and the more general adoption of improved machinery. The bulk of the shipments is in the form of fine bar copper, though both regulus and copper ores are exported.
Digitized by VjOOQIC NITRATES AN ALADDIN'S LAMP 229 The coal mines are located in the Provinces of Con- cepcion and Arauco, the most productive veins being at Lota and Coronel.
