Mines and Mininq

ore has been shipped from this shaft, ] the product being copper, silver and |, gold. The Winkelreid claim has a ten foot shaft, the Tillie twenty feet, and the Pivot ten feet. The Baby has two small shafts ten and twenty feet, the Bessie ten-foot shaft, and the Laura seventy-two feet. This represents the entire development of the claims thus far. About fifteen men are being worked at the camp under the direc- tion of MT. Baumann.
 The claims are located in a great porphyry belt which extends for miles through the Agua Fria mountains from the northeast to the southwest. Gran ite forms the eastern contact and is the footwall of the mineral. On the west side of he porphyry is a porphyritic slate and then pure slate. A great clay gouge goes with the mineral and often is found to contain copper, and in one of the shafts the gouge is highly impregnated with mineral. The ship ping ore is found in quartz which rests upon the gouge and is formed in layers something like slate. The great quartz lodes have been penetrated considerable distance. but no hanging wall has yet been found. The character of the ore is metallic copper sulphurets, carbonate of copper and oxide of copper.
 In the Swiss Girl tunnel the ore is found in porphyry at the beginning of the tunnel. but quartz ,oon takes up the values and this gangue finally yields to and is almost absorbed and lost in mineral. Sulphide ores are en- countered at a slight depth, but the greatest value is in the lowest work ings. The claims are scarcely devel- oped, yet there are immense bodies of ore opened up in several places. The trend of the mineral is clearly defined and revealed by shafts and prospect holes. Shipping ore has been found in the Swiss Girl, the Alice, the Baby and Laura, and each of these claims has provided considerable ore for the smelter. The Arizona claim also has shipping ore. although as yet none has left the dump.
 These claims are located in what is probably one of the richest copepr zones in Yavapai county. The work ings simply indicate what is below. but the promise of opening up great bodies of sulphide ores warrants the expenditure of large sums to gain depth. Mir. Baumann located the Swiss Girl claims fifteen years ago and he has stuck to them without for a day losing confidence in his properties. When the shelter starts up he hopes to become one of the largest shippers. His camp is about two miles from the Val Verde smelter and is reached by a fine mountain read.
 Mir. Baumann has bonded his claims to Col. D. P. Bosworth of New York for three months. and the colonel has already secured subscriptions to the stock sufficient to buy the properties outright. He proposes to operate the claims extensively and has great faith that here is the making of a second United Verde. The Swiss Girls ore was placed upon exhibition at the worlds fair and MT. Baumann was awarded a diploma for his excellent ex- hibition and the rich character of the ore sent. Aside from the copper values the Swiss Girl produces gold and silver and often the latter values run very high. The ores are siIicious and this makes the smelting charges unusually high. But MT. Baumann has shipped ore for years in spite of this and has made considerable money out of his properties. With deeper workings the Swiss Girl is bound to become one Of the great copper mines of Arizona There is mine here above the water level. and when the sulphide base is rached it will be a bonanza.
