GOLD PRODUCERS.
The St. Patrick and Orc Blanco Gold
 Mines,
THE ORC BLANCO MINE.

THE ORC BLANCO MINE. The Gro Blanco is the oldest mine in the district. It is, as may be inferred, | the mine from which the district took its name. It was worked perhaps hun dred years ago, in the old Mexican method of open-cutting along the vein, removing 1t by carrying the ore on the | shoulders to the surface. in rawhide buckets, and then worked in arastras. It paid to work Tn tbIs crude fashion, and ] it still has almost as much ore as it had thirty years back.
 MINE WITH HISTORY. On the flat below the mine were a large number of arrsstras. One of the early corners says there were 23; anoth- CT says 47. At any rate there were a great many, for the stones therefrom contributed largely to the enclosure of little ranch on their site, where today grow the vine and fig tree, cereals and all that makes little ranch handsome veritable Oasis in this forbidden re- zion of rocks, mountains and canyons.
 Then came the clash between the M-xicans and Americans related some issues back. The Mexicans, who would work harder for revenge than money, took all the waste at hand and filled up the cut. Then they departed for Sono- "a, burros, baggage and all.
 Thus the Gro Blsnco lay for years. Eve h ipp 6ociro hla in fbot l;ofr;ot ;r those days was silver, gold lodges being fifteen years ago, since which time it has had various owners.
 The present owners, Messrs. William Perry and A. E. Began, developed it last year. The depth is now 50 feet. They S2050 per ton at the Yellow Jacket mill. erty.
 The ore is porphyry. in diorte con- tact walls, with an average of 515 feet of ore.
 The mine is now under bond to Don Pickett, of Tucson. The prospects are good for the old Gro Blsnco being as hectipg it's share of credit on the dis trict bearing its name.
 THE ST. PATRICK AND BOSTON MINES.
 With almost no development what ever the St. Patrick was sold in the fall of 1892, bringing S5OOO. It is an ore body above ground, and was bought by the purchasers ID preference to the pro- perty now known as the Old Glory. It is another quarryiug proposition, al- though the vein beneath the reef has been found. This vein was F feet thick Samples from the vein ran S30 ton in gold, but this was no criterion of the whole proposition. Good samples were taken from there. From the reef, mill tests, made at the Austerlitz mill, and most practical showings of the entire ore body, resulted in over S9 ton, in gold.
 The intention was to follow the purchase of the property by the erection of a mill,-but about that time the late financial panic came on, and the where withal for the outlay was not forth coming. A big plant be erected there, however, as sOon as one of two arrange ments now under way can be decided on.
 The mine is the property of Messrs. Mitchell & Go.
 Across the canyon from the St. Patrick, their locations coming side by side, IS the Boston mine. The ores of the two run into each others location, but they are not the same lead. The Boston is a property now m the course of development. It has the feature of being, with a single exception, the only mine In Gro Blanco carrying sulphurets in large quantities and this late dis covery. The sulphurets underlying the Boston are supposed to overlie the St. Patrick.
 The sulphurets were struck during the developments, when the tunnel was in 42 feet. They were clearly defined, assRying for average, SIS gold and g OF. silver per ton. The advantage of ledge of sulphurets is that it IS more uniform than free gold proposition, and reduc- tion methods can be more safely figured on. As depth is attained with free- gold proposition usually when down about hundred feet it changes into sulphurets. This requires a new plant. But with eulphurets from the inception concentr8tors can be provided and work go on indefinitely with no change. Sulphurets in the Boston 60 near the surface are accounted for on the ground of lack of lead ID the ore, which metal in certain combinations is an active 6ecomposing agent. Development on the Boston is 90 feet. The sulphurets are now being developed. The owner ship of the Boston is the same as the St. Patrick.
