THE ARIZONA COPPER MINE. 



BY JAMES GILBERT. 



Read before the Canadian Institute, iMh December, 1856. 



Various causes have combined to excite a greatly increasing 

 interest in the mineral wealth of this continent ; and while our own 

 valuable, though still unwrought, Canadian copper region naturally 

 forms the pre-eminent object of such interest, as pertaining to our- 

 selves and constituting a source of future enterprise and wealth, it 

 will not probably prove unacceptable to the Members of the Canadian 

 Institute to learn somewhat of the mineral wealth of the south-wes- 

 tern regions of this continent of North America, as illustrated by 

 the Arizona mine, one of the richest copper mines hitherto noted in 

 the mineral regions of California. At the same time the history of 

 this mine, while it directs our attention to other depositories of un- 

 wrought mineral treasure, abundantly illustrates the obstacles which 

 had to be overcome before such could be turned to profitable account. 



The information contained in the following brief notice was ac- 

 quired during a recent visit to California. The Arizona Copper 

 Mine, is situated in the Gadsden Purchase in latitude 32° north, and 

 longitude 111 Q 45' west ; being about 110 miles S. E., from Fort 

 Tuma, and 35 miles from the river Gila.
