THE SILVER KING MINE.
The Financial and Mining J our1sal's Opin-
 ion of its Condition.
(New York F. & NJ. Journal.) )

l6dSb very unllkeIy, lIldl d HllllC SnOtlu become suddenly barren below the depthsof 500 feet from which above that depth, has been won so large an amount of almost every description of silver ore known toZne mineralogist, and which, between the third levels has given up such exceptionally large bodies of rich as well as fair grade ores, and especially one that has yieled in its upper stopes so much native sil- ver-facts which certainly indicate a genesis from igneous elections from below rather than one resulting from aqueous dispositions from above. Such a genesis is further indicated by the very nature of the outcrop that was so rich in nuggets of argentite. Accord ing to Professor Blake, as much as one-third of the product of the mine ap to the 1st of January, 1883, was native silver while the stopes of the seventh level had been rich in masses of native silver associated with stro- meyerite (sulphuret of silver and cop perl and blende < equal to any seen in the upper levels.
 l somewhat of the history of this mine. It being known that soldier of the Regular Army had. found somewhere on the surface in that quarter nuggets of silver-in 1875, a party of prospec tors from Phoenix set out to hunt for the locality, and one of the number | Copeland by name) happened to find it. That is, he found spot strewn with small black nuggets of silver sulphide and the exposed rocks show ing green and blue mineral stains. This was on the 22nd of March, 1875, and a claim of 1,500 feet east and west by 600 feet north and south was at once duly located and recorded in 1 the name of the four men constitut- ing the party, under the erroneous idea that the course of the vein was an eastern and western one. The follow ing year two of the owners, Messrs. Mason and Began purchased the interests of the other two. Some
 months later MT. J. M. Barney acquired half interest, and some what later the present company was organized to acquire and operate
 the property.
 The first exploitation of the Silver
 King was by an open pit to the depth
 of 120 feet and about 115 feet by 92
 feet, out of which were excavated a
 so-called porphyritic gangue matter
 filled with masses and punches of ore
 interlacing veinlets of native silver
 carbonates of copper, horn silver
 malachite, native copper azurite
 bromides of silver and argentite in
 black Jumps of pure silver. The
 mouth of this cut is so feet above the
 mouth of the shaft by which the mine
 was subsequently, developed and work
 ed about 200 feet westward of the
 western limit of the pit. Out of thi:
 ore to the money value of at least one
 million of ciolltsrs was extracted -bN which time 1t had become too lean tt
 work, therefore, shaft just mentioned was located and sunk to cut the veil on its dip to the westward which wa virtually effected at the depth of 30; feet between which and 354 feet, by 1882, as much as 9,792 tons of ore haC , been extracted ore of high grade, yer! l rich in igneous silver, without having } reached Gas late as 1S82) any defnit' limits of the ore though the floor o the third level was 64 by 43 feet il area The western limits of this foo l was to the east of the shaft, as was al Q so that of the 4th or 40S-foot level g from which were extracted 13,37S ton of ore largely very rich. The shaf
 entered the mineralized rock belo'
 the fourth level-while the sixth leve
 at the depth of 570 feet and stopes ar 9 to the west of the shaft. The sevent a level run at depth of TIA feet wa a the lowest level opened anterior t 3 1883, by which time 16,623 tons of or @ had been extracted from 1t.
 . A glance at Prof. Blake's sketch ( . the vertical line of the vein from tn Ii open cut or pit to the floor of tn e seventh level at the depth of TIA fee ,. would seem to show-coupled wit e the excavations made above the dept }, of 300 feet since 18S2-that contil r uous unbrollen body of mineralize ,s rock has extended from the surfac d with westward dip and greatly wider es ing as it descended-or rather sharpl is narrowing as it ascended to the SUI lee face-at an angle that ought to carr 'a q its western limit across into the Bil v ground at the depth of 1000 feet, a. not sooner. And in support of tn ct supposition, we may cite the fact tn; In Aaron Mason, for long time one III the largest owners in the Silver Kin ,o Eo as well as its superintendent for year ~ 1o and than whom no one knew more oe the underground character of the Si
 yer King property, became the prime
 pal owner of the Blk, and under h
 superintendency a large sum of mont
 was expended by him and his frienC .,, in sinking the shaft on that proper III III now owned by the Silver King Cor ne ne pany, with the avowed purpose h reaching the Silver King~ vein on i li- dip into the Bilk. .~this, having bee he done under the erroneous idea tn Id the western limit of the Silver Xii iq e1 as located was an lend line," where itS tS it really or in effect is "side lin in and hence, according to well settl to decisions of the Supreme Court of u
 United States, the Silver King Col
 pany own the veins or chimney of o
 on its dip to the centre of the cart ia The present ownership of the Blk
 the Silver King Company will enat
 them to work the Silver King vein
 any depth below 500 feet, much bett 1g than from its own shaft. Subseque1 ln ly, the continuity and dip of the c
 body between the bottom of the sl
 face pit and that found below 300 fe or- would seem to have been essential
 demonstrated by the stopes operat sk at the depth of 119 feet and 250 fe le. raSnectivelv
