MINING IN PIMA COUNTY.
General and Specific References to
 Actual Work.


 activity in mining operations. Thus far our people have done no mining on paper but upon tunnels, shafts and surveys. No attempts worthy of mention, if any at all, have been made to lure others here to ex- pend their cash upon our mines, but our own merchants, professional men, office holders, mechanics and common laborers have been expending of their time and money in seeking out and developing lodes of gold, silver and copper. Enough has been done and is continuing to be done by actual and longtime residents of this county to show that those best fitted to judge aright, are now more than ever be- fore convinced that the mines of Pima county are of great value. We do not expect to give history of all that is being done at this time, but will refer to enough to convince candid men that what is said above is truth.
 Early in 1875, c. O. Brown and others made frequent prospecting tours into the mountains some forty miles west of Tue son, and discovered many abandoned mines of silver and copper-notably the latter. Subsequently, Fully, Ochoa 6l Go. and E. NJ. Pearce became interested with him, and from time to time die some labor until early in November when they put force of men, well provided with min ta fl, Mammoth lode. A shaft in size 5x6 feet IS now down sixty feet and will be con- tinued right on to at least 100 in depth. They have well-defned wall on one side of the shaft, and have not made a cross cut of the vein to determine its thickness, but it is probably entyfive feet. Assays in San Francisco show the lowest per centage of copper to be fl and the highest S9 per cent, and the silver runs 24. 3S. They have procured 800 sacks for shipping ore and sixty tons will soon be on the way to San Francisco. During this year they intend to ship at least 800 tons probably all to San Francisco. As soon
 
 down on the Mammoth, they mean to open the young America which is about p feet in thickness on the top and there tue ore is from 20 to 60 per cent. metal, and thousands of tons of such ore lies on the surface
 For some months past E. N. Fish and D. A. Bennett have had men employed in sinking shalt 100 feet deep on lead and silver vein in the Patagonia mountains, about 75 miles south and east of Tucson. The shaft was recently completed as per contract. A vein was disclosed all the way down of 2119 to feet in width The ore contains 75 per cent. of lead and con- siderable silver. They hope to make an arrangement to build a smelling furnace to the rear of the Tucson Touring mill and by the economy in power thus obtain ed and cheap labor easily secured here, to justify them in shipping ore here for re- duction. They intend to go ahead with the work and have unbounded faith in making the mine nice paying one.
 Gov. Stafford, Dr. J. c. Handy, J. w. Hopkins, R. N. Leatherwood, J. D. Fry and Thomas Gardner commenced devel- oping, in 1873, the Trench mine which is situated about sixty miles southeast of Tucson and on the north slope of the Pa tagonia mountains. They have expended over $500 in cash for work and materials for reduction of ores. They now have two furnaces and other appliances for smelling. Within week, they have con- tracted with A. G. Elliott to take out ore and smelt enough to make ten tons of bullion, at S60 per ton of metal, with the privilege of increasing the mount to 100 tons-the proprietors to receive the bull lion at the mine. Heretofore small work ing tests have been made, MT. Gardner having recently smelted 1000 pounds and obtained B per cent. of lead and 115 pounds of silver. Another 1000 pounds is out which he believes will give much larger return in silver and no less of lead. The bullion will be shipped to San Fran cisco for parting and refining. Aside from the general prospecting on the lode, there is shaft down twenty-five feet which shows about tweDtytwo inches in
