Bisbee daily review., 1910-10-09

company lies the Giroux Consolidated
 Mining Company, upon which pres lent developments indicate some fiji.
 cen million tons of similar ore, but I f slightly higher copper tenor. and
 ct she greater portion of its probable roduetiye area is practically unpros-
 lected. In fact the possessions of
 his company cover the mineralized
 porphyry from the CumberlandEly
 on the west 10 the Nevada Consoli-
 'ated on the east, distance of con I fderably more than mile, being equal in extent to double the mineral ized area owned by the latter named nJmpany. The workings of these
 .djoining properties are each in ore
 of more than average grade imme- diately at the extreme east and west
 boundaries of the Giroux mines, all
 f which indicates the probable exis-
 ence within the boundaries of the Giroux properties of more than six
 million tons of porphyry ore of
 equal commercial value to that of
 he Cumberland-Ely and Nevada con
 olidated mines, and which must be
 taken into account in any plan which
 seeks to protect the metal trade from
 oyer-supply of cheaply or reckiessly produced copper metal
 In addition to its porphyry ores, the Giroux company is now rushing ito complete the equipment of its
 new fiye-compartmen shaft. through which the high-grade direct smelling
 ores developed in the Alpha shaft svill soon begin to move 10 the Inter
 national smelter. These cres occur
 in vein of the ''old-fashioned" type
 which has been developed rom the TOO down to the l,200-foot level. and
 has an exposed width of more than seventy feet of ore averaging at the 1000 and 1,200 foot levels well above 12 per cent copper, in addition to important gold values. The purchase of the Rickard-Ely and other large blocks of ground on the west by the Giroux company. together with the
 boring of numerous diamond drilR
 holes therein. indicates the discovery of continuation of this great lode for a distance of at least $500 feet in a westerly direction from the Alpha shaft In addition the old Giroux shaft which is situated some 600 feet to the north of the Alpha vein has been sunk to depth of several hun dred feet upon a parallel Assure vein in limestone, exposing an ore body Of about sixty feet in width of excellent ores. containing from 3 to s per cent copper and also important gold values. And then there is an- other oid-fashioned Assure vein on the Giroux property on what is locally known as Pilot Knob, which thus far is practically undeveloped, but which 1 out crops several feet above the sur rounding surface and has width of more than 100 feet of ideal fiuxing ore, in which the goIi values alone 1 1t is said. are suffi cen to afford good mining profi: These old | fashioned veins will produce copper at lower cost than the most favored porphyry mines and they have length and breadth, and will continue to the deep and will suIyIva and thrive long after the porDlyrv mines shal; have expired, ard must therefore als be taken into accounL in the distribu ton of fayors among the cheap ITO dacers"
 Now it is quite possible that i'm portant errors of judgment, miscon- ceptiou of premises or even sinister motive may have entered into the es- innate of net profit derivable from the enormous volume of these new found porphyry ores which it is claim ed are to control the worlds copper metal trade. Possibly in time the fact may be discovered that drill holes sunk even at intervals of 200 feet distant do not afford bankable assur- ance that all intervening space is oc- cupied by merchantabie ores. and that even tunnels and shafts, which may be driven in valuable ores at much shorter intervals of space may have been luckily or wisely directed along enriched channels. bordered by prac- tically barren. or worthless ground |
 We have seen the metal trade and the share market paralyzed with stor- ies of the fabulous wealth of prodigi- 1 ous ore bodies claimed to have been i developed in this manner in the great est of these wonderful" mines in the short space Of three or four years | time. and then we nave seen t,Iis same great mine, within a much short CT time, practically stripped of all | commercially valuable ore so that more than hundred million tons nf !! the supposedly precious stuff dissp- peared like thief in the night and | all because the existence of this stu pendous ore body had only been in ferred from openings which were con- fined to enriched channels wnic.i sub sequent developments proved to 5e enclosed within narrow limits by worthless rock. And so in like mar ner may disappear muc1 Of the vast 1 fonnaQa claimed .o ox;Sf ia xthor
