ne iNln Peaks Mining com pany's properties lie on the border of New Mexico-Arizona. g miles rom Duncan. Arizona. and the properties are so named because of two very prominent peaks uplifted above their fellows, and which may seen for many miles in any di-
 ection. The property was discover cd several years ago by James Fra ser, and little later he interested his brothers, Daniel, Alexander and Joseph. and their brother-in-law, 4 W. NeYhouse. These five carried the burden of development for more than a year, when a company was formed anl friends and business as sociates assisted in the work until today they have a well-developed property, having real worth.
 There are 10 claims, or 15.O00 feet. on the vein traversing the country in a southwest-northwes direction. this vein being an average of , feet in width. Throughout it's length it carries free gold, in value over s5 and the average in the working is above s15. Much excep- tionally high grade ore has been en- countered. and it is yet coming in at the 100 and 200 levels in the main working shafts; and in the two oth- CT deep shafts there is considerable high grade-but of course the worth of the mine is based on the larger quantities of medium grade. There
 S now much stoping ground in the
 hree deep shafts Of better than s15 material.
 The country rock is andeslte and yhyolite. apparently overlaying
 ,ranite. the latter at great depth to 'udge by exposures found two miles below the mine. The vein is a true essure. Paraneling the vein is a very large porphyry dyke. mineralized to some extent. This trends downward toward the vein. and if the dip con tinues as in the past there will be a conjuntion at something like 400 feet. As values and ore increase with depth. demonstrating that on the surface the matrix has leached con siderably. it is expected that the better ore bodies, both as to quanti- tv and values, will come in when he contact is reached at considera- ble depth. The surface ores are free. and this continues down to below the 100 level. where, to the east of the shaft, sulphides have come in; and here the values are better than at less depth. The sulphide is a eeavy black material. carrying some silver values, as well as gold, hut there is DO refractory content, thus making an ideal cyaniding product The formation here is very deep, rroyen by the exposures in Apache Canyon and also at the point where hydro-eIectric plant will probably Ne installed. There are 3 deep -hafts-one 20 feet, one 160 feet, l nd one 200 feet. On the 100 level in toe latter drifts have been run east md west, the former 70 and the alter 90 feet The shaft seems to | ~ut the ores, as to the east 1t is | sulnhide and to the west 1t is stin 9xidized, gold being free. There Is | q full face of the latter, and the

 As the vein Is not exactly perpendie

 shaft from the 100 down, but at th' 200 level there is aho"t feet O l sulphide material carrying valne'

 There is a 70-foot tunnel near tH

 The money secured for this pro' srtv has certainly been put into it and the result is quite satisfactor, There has heen deveIoued here business justifying whatever outls necessary to the making of a min' The owners were fortunate in secu ing a 100-ton r'ill from a refun' company for s2.s00 th=t originall l cost s5s.0o0.
