PEDRAZZINI MINES

Brown. mine captain; Matthew van Slelen, chief engineer and sgperin- tendent of Carmen mine; H. W. Aus tin superintendent. The production at this time is not up to the standard Tn quantity. due to the installment CT machinery and to the political troubles: but as the former are now about completed and the latter not so serious for the mines because of the necessity of the people for em- Il9ymeDt. the general OutJut win considerably increase very soon. The veins in the Chispas ground are Assures in rhyolite and rhyOlite and andesite breccia. the ore cutting the formation at right angles. The ore is silver, with a small percentage Oi geld, and oftentimes native silver ia found. It is not uncommon to find a pocket of ore that will run 50 to so percent silver. The ore is usually a ulphide-argentte, proustite, ste phanite, pOlybasIte, and 1t runs high grade always, sometimes so rich that it is sent direct to the Selby smelt- tug works at San Francisco (the concentrates from the mill are sent to the Fl Paso smelter) Some of the sulphide ores run above 1500 ounces to the ton. The walls of the Assure are clean and clear always and there is little variation as tC size. The beds of rhyolitc and and csite lie atop each other horizontally, and movement is noted by the ande- site lie above cath other, horizon tally. The movement which per nitted the Assuring is noted often
 times in tho vein as on one side the bedding plane will be on the other. The vein has been found as productive of good ore at 7JO feet as at less depths, and at this time one is coming from 600 and 750 feet, and a few days before my arrival in the camp they had just worked through a very good stope of b0- manga on the 600. All mining is done by contract, and it is all hand work. There is regular inspection of miners and clothing, as otherwise much "highgrading" might be done.
 The ore is sorted in the patio as it comes from the mine, and the high grade is taken immediately into warehouse where it is sacked for shipment direct, while the millina ere is sent to the plant as ordinary. medium and lowgrade. During the past month they have run mostly on ore from the William Tell vein, this bringing up the gold production materially. as this vein carries more gold than silver. The ore from the mine is taken to the mill in trains of three cars each holding 2 1-s tons, and all hauled by a gasoline locomotive over narrow guage tracks about one mile in length. A notable feature in the mine Is that the
 mileage" is in ladders instead of rails. as in most mines. There are ladders everywhere, and the way the
 Mexican miners shin up and down
 them is an interesting exposition. There is here, as always, great ex- citement when petanne tor excep- ti1nally high gradey is found, for th- men seem to take the same interest in this as do the stockholders.
 The Carmen Mine.
 This property is owned by the same people in the Pedrazzini com name Minas Mercedes. Matthew van Siclen is superintendent. The prop erty is named for a silver-lead mine called the Mercedes, but the Car
 men is the principal operation at this time. The Carmen has a shaft down 600 feet, and there are mum erous tunnels and shaliower shafts winzes, etc The production here has been considerable in the past, and there is. at this time considerable good milling ore in sight, but no
