31 Industrial Cuba 



This mine has been leased to a Havana company 

 and is being profitably worked, although on a 

 small scale. The ore yields from twenty-two to 

 twenty-six per cent copper to the ton. 



The greatest activity in copper mining has been 

 manifested in the province of Pinar del Rio and 

 the copper field apparently ceases in the eastern 

 trend of the mountains, to reappear in the peaks 

 near Trinidad, in the province of Santa Clara. 

 Rich finds have been recently made, but are 

 being worked only on a small scale. 



In Oriente there is a great unexplored region 

 that will some day make Cuba famous for her 

 mineral wealth. 



PRESENT COPPER MINING STATUS 



Number of active mines 42 



Gross output of ore 65,000 tons in 191 5 



Average per cent fineness 15% 



Operatives employed About 5,000 



Exports during 191 5 64,532 tons 



This section is extremely rich in copper, nickel, 

 manganese, lead, silver, and occasionally, gold. 



In the Sierra de Cubitas mountains, paralleling 

 for fifty miles the north coast of Camaguey, iron, 

 copper, manganese, chrome and other minerals 

 are found, but with the exception of such develop- 

 ment as has taken place in working the iron 

 holdings, no serious effort is being made to inves- 

 tigate or develop the other mining opportunities 

 of this field. 



The building of the north shore railroad, a 

 spur of which will be sent into the iron deposit 

 section, will have a tendency to develop the metal 

 industry.
