CAREFUL DESCRIPTION OF MINES IN FINAL COUNTY OWNED
 BY GOSHEN BROTHERS.
Property Consists of Six Quartz Claims Carrying Gold, Silver and Lead Development Work Being Continued on Small Scale.

 Dudleyville, on the Gila river. These mines recently attracted much stten- ion because of the fsbulously rich ore taken from 6 shaft, being sunk for development on one of the claims. Mir. Heffern makes an encouraging re- port and it is hoped that the owners of the property who are continuing de- velopment work will find that the re- port which follows IS conservative in it's estimation of value:
 Geological report by Professor Albert Heffern. geologist and mining engi' neer, of Bisbee, Arizona. P. 0. Box 279:
 Bisbee Arizona, Feb. 15, 1904. To the directors of the Fl Dorado Gold & Silver Mining company, at Douglas, Arizona. GentIemen:-In harmony with your instructions I have examined your property situated six miles east of Dudleyville in Pinal county, Arizona, in the Saddle noun. tain mining district and I submit the following report upon it:
 The property consists of a group of six quartz claims carrying values in gold silver and lead.
 TOPOGRAHY
 The topography of the country is rough, through easily accessible by wagon road from the west side to with. in one mile of the works, by the way of Dudleyville.
 abruptly from the San Pedro valley has a northwest and southeast trend and is cut by canyons north and soutf about mile apart and this property is on the north slope of the hills. Thi highest point being about 20OO fee' above the San Pedro valley.
 FORMATION
 The entire country is a great stacs of micscious diorite, granular diorite hornblend audeiste, augite audesite porphyry and porphyretic diabase. The district passed through three per rols of volcanic disturbances. Eacl disturbance has its own vein system.
 The ore deposits are practically co extensive with the great porpbyry stacI and it's dyke systems. The veins occul either in diorit porphyry or along it contacts with the audsit porphyry This intimate connection with the DOT phyry is certainly ID important fact.
 want to emphasize the fact tha this formation is identical to that O the world famous Comstock mine a Virginia City. Nevada. that has beel worked ever since the year 1859 to tn present day and has produced million of dollars worth of bu llion.
 ElN . Em
 Tie principle loaes strike Gc.tEss and southwest, here are five vein within a sort distance of one anothe and their outorops can be seen on tn urface for two and one-half miles Ranging Tn width from the two fee up to fifteen feet. The veins are mar ked at their outcrop by quartz eithe containing free gold, sulphides, silve end lead or the oxides of iron an manganese.
 Free gold can be banned from tn outcrops of these veins and gold ow being washed from the bottom o the guIches in his immediate district which has evidently been removed b erosion from these veins. 1, The gaugue matter of these vein consists of fine grained quartz, irol sulphides. iron and manganese oxide and cslcite. I will emphasize the fac that this gangue is always found il gold, silver and lead mines. It is th gangue at the big mines at Tombstone Arizona. CsIcite and iron oxides ar the principal gsugue matter of th' Copper Queen ores and Calumet d Arizona ores, of Bisbee.
 FUEL
 Wood for fuel eau be had along tn, San Pedro river seven or eight milel from the property.
 WATER
 Water in winter months can be haC anywhere on the property. In the sum mer months can be had at the GIls river, one mile from the claims.
 ROADS
 The roads from supply points srt practically level to within one mile oi the camp, for one mile all freight mus at present be packed to camp. think that a good wagon road can be made
