Bisbee daily review., 1905-05-21


 that property:
 President John Daniell of the Noa verine & Arizona Mining company has recently returned from a visit to the property. He states that work at present is confined to the extension of drifts at the 300-foot level and 800 foot level. The 3OO-foot level drift is an undertaking but recently started and the work has progressed about 100 feet. The 500-foot drift has been in progress for long time and about 1,5OO feet of lateral openings have been extended at that level. The breast of the drift itself is almost 800 feet from the shaft.
 The general course of both drifts are the same. the direction being somewhat west of north. As the shaft is sunk in the center of the Bro ken Promise claim toward the south eastern part of the property, the urlrts as they are now being extended, will be capable of exploring the entire eastern end of the Wolverine & Arf zona holdings.
 The objective point toward which the drifts are extending is a serles oI faults which strike across the proper ty in the central and eastern central portions maintaining a general north and south course and varying some. what from parallel. These faults branch out like fingers. from a Dor. phyry intrusive dike with an east and west direction near the northern boundary or the property.
 EgTEn0ino infn fhfc dike from the north is a prominent fault which is a leading feature in the geology around Bisbee This fault is clearly identified on the United States geological survey map as cx. tending for a long distance in a north and south direction. It is crossed at two points by prominent purpnyry intrusive dikes. One of these dikes is the one meItioned on the Wolver. inc & Arizona property, 5000 feet northward.
 It is close 10 the junction of the porphyry dike and this fault that the Sagniaw people have sunk their shaft, and they have recently come into . body of good pay ore. Apparently the several faults to the south of tie other porphyry dike, which strike sOuthward across the Wolverine & Arizona property. represent a split ting Of the prominent fault leading in. to this Wolverine & Arizona dike from the northward.
 The geological theory concerning these formations is that the porphyry forced it's way upward while in a mol ten state through a fracture in the limestone. The intense heat from this source burned out the volatile DOT. tions of the limestone and left it in a fragile state, easily susceptible to dis. tntegrarion, for a considerable dis tance on each side of the porphyry intrusion.
 The faults in the limestone are frac- lures which are filled with a second ary deposit and which have been the courses for underground waters, bear. ing minerals in solution. When these acid waters, flowing through the fault channels, came into contact with the fragile limestone burned out by the porphyry intrusion, the lime gave way very readily to the action of the water, and becoming permeated with it, formed a natural medium for the pre- cipitation and deposition of the min. erals contained in the water.
 As a result there is a tendency to look for ore deposits in the angles of an intersection between a fault and a dike. It is toward such a geological formation that the Wolverine & Ari. zona drifts are pointe4 At the 400 foot level the drift has approached to point from which it is expected that the first of the series of faults will be reached within two or three months. The work has been progressing through hard and unaltered limestone, but during the last four or five weeks it has opened a slightly softer forma- tion.
 There has been more or less talk from time to time concerning the ad. visibility Of the Wolverine 6 arizona attaining greater depth, the argument being that the Bisbee mines have al most invariably found it necessary to put their shaft down 900 feet or so before coming into good ore bodies.
 The policy of the Wolverine & Ari. zOna management will be to hold this matter in abeyance for the present however. The water question enters into the subject in an important and unusual way at this property. It was found that the water could be kept at the 500-fOOt level. or a few feet below that point at practically no expense for pumping. But to keep it at the 665-fOOt level. which is the bottom, would cost at the rate of S5O,000 a year, for maintaining and operating the pumps alone.
 For this reason the work at the 500-foot level was commenced and the drift at that point so directed that it entered rapidly under higher ground, giving it a constantly increasing yer. tical distance from surface.
 Then came a very pleasing and promising turn of affairs in the water question. As the properties in the Calumet & Arizona sisterhood, partic- ularly the Calumet & Pittsburg. which had an exceedingly heavy inflow Of water, got their pumps into good working order, there was Q sudden re- cessiOn of the water in the Wolverine & Arizona shaft.
