Geologist ( 1' J" eeson, who is emploded hy ,MiC?m,pany' Ported yesterday that the arm hole now shows twentv-one feet and lthes of ore tho lowor portion of the noie naving entered the hreceiated ma-strlke- '' Bee&on in discussing the We have encountered hiph-pcrade snver-bearincr lead ore in hole. No. 4 at a deupth of sllslitlv over 210 feet nelow the Bay city tunnel level, at a point about 140 feet northeaat of tho Montezuma fault. In three previous holes at a depth of ISO feet we encountered en-countered favorable conditions. In pole No. 2, for instance, a one-half-mcli streak of galena and quartz was cut below a hreceiated zone, and where we have the ore is on a line with this horizon, the additional depth apparently bein- due to the inclination in-clination of the strata. The holes so far put down are arranged ar-ranged radially with No. 4, or the last one as a center. No. 1 is situated sit-uated eighty feet to the southwest. No. 2 is eighty feet to the south, and No. 3 eighty feet to the southeast. I am satisfied in my own mind that the ore encountered is a continuation of the famous Old Emma ore bod v. This la borne out by the fact that in each of the holes at tnis same horizon hori-zon favorable indications have been mot with, and, further, because hole No. 3 showed conditions almost identical iden-tical with those seen in the limestone , exposures just south of the Old Emma Em-ma mope near the surface. 1 In further explanation. It mav be said that at the surrace there are certain distinctive geological characteristics char-acteristics in the way of mineralization minerali-zation and texture of the limestone beds tying adjacent to the ore bodies in the footwal side of the fault that we find duplicated in the faulted portion por-tion of the limestone below the Bay City tunnel level on the hanging wall side of the fault. This increased in-creased our confidence in the successful suc-cessful outcome of the operations which we were carrying out. The ore encountered in the drill hole Is somewhat different in character charac-ter to that which was mined in the Old Emma stope. because, in the upper up-per workings, the ore was almost completely oxidized, while the ore cut in the drill hole shows no oxidization oxidi-zation or alteration whatsoever. Further, Fur-ther, It is much more silicious. The core shows galena and pyrite disseminated through a compact mass of quartz, with here and there small cavities lined with well formed crystals crys-tals of quartz and galena. Argen-tite, Argen-tite, the sulphide of silver, apparently is also present. This is further evidenced evi-denced by tiie high silver values contained con-tained in the first part or the core which was sent to be assayed. Ttie xinoxidized nature of the ore and the apparent absence of secondary minerals min-erals and the large amount of quartz in the gangue, leads to the conclusion conclu-sion that the high-grade ore encountered encoun-tered will persist to depth. The character of the quartz as shown in the core Indicates that the mineralization minerali-zation has been effected by deep-seated deep-seated solutions coming up through fissures in the rocks and replacing the limestone. It could not possibly have come from waters infiltrating' from the surface. Tn hole No. 2, eigthy feet away, the half-inch of galena is evidently connected with the body cut in hole No. 4. as was intimated at the timo hole No. a was put down. The importance of this strike cannot can-not be overestimated. The actual visualizing of this ore is the only remaining proof that was needed in the chain of tarts which have been gathered. It may be stated without exaggeration that the finding of high-grade high-grade ore of this character may be taken as proof that the same continuity con-tinuity of mineralization will be uncovered un-covered by the development work which will be undertaken as soon as possible, as existed In the workings nearer the surface on the foot wall side of the fault. There are a number num-ber of strong fissures that have produced pro-duced considerable quantities of ore in higher beds on the hanging wall side of the fault, proving that the mineralizing agencies were as strong on the hanging wall side as on the footwalt side of the fault, and lead to the ronviction that as development 'proceeds the unworked portion of the deposit will he found to be of greater magnitude than the part already worked. |
