SILVER KING,
The Outlook as Flstterins for the Future
 As h Has Been in the Past.

oeasingly on and as old ground is work ed out new ground is opened up and the bullion contributions to the coun 'ry still goes on. Under the superentend. ency of Mir. Arthur Macy, brief syuop- sis of whose report for the year ending January l. 1888, we here append. Many improvements have been made looking to better and more economical work ing of the mine, and closer working of the ores at the mills than formerly by the various new processes he has intro
 duced.
 The mining operations for the year ending Jan. l, 1888, have been carried on without a single days interruption and the amount of dead work performed ID driving tunnels and sinking viDzes has been greater than at any tune be- fore in the history of the mine. | During the summer 6 cross-cut tun- nel was run from the old drift on the 1l9 foot level to discover and perfect the ore body which evidently existed st that level and which had been located by surveys. The ore body was encouD- tered about l2 feet from the old drift, the tunnel trsversing the north side of 1t a distance of 50 feet through bsrytO- quartzose material similar in character to that of the level below, and exhibit ing mineral constituency of gslens, zInc blende, fahlore, native silver and cbalcopyrite. The total length of the tunnel is 9S feet, 1t having been run some 26 feet into the country rock to determine the non exist nee of any min eral bearing ground beyond the quartz. Assays of pieces of ore tskon st random from the broken mstersl at various points in the progress of she tunnel, which would be classified ss ordinary sorted ore, gave an average of SS 3S-lOO OF othe ton. A selected sample which contained mostly fshlore, gave sn assay value of AT 40 100 or. 10 the ton. The general showing of the ore body ss eI- posed in the tunnel l. fully as sstistsc- tory as is usually discovered by such workings ID the mine, snd its length is probably ss great ss it's width, Was found to be at the end prospeoted. Tnis ground stands intact and should reach 1 nesrlY to the surface. or to the bottom of the old ''open pit" which is about thirty feet below the collar of the shaft. In the extraction of this ore, the present opening st ll9-foot level will be abandoned, and the sill floor of 6 new level established, which will be known ss the l43-foot level and operst- ed through shaft No. 8 North Kingl.
 Th- 250-foot level hss been actively worked the greater portion of the year, producing the bsrytoqusriEose which was irssted by special roast cblorins- tion and smglgsmstIon. This ore, dur ing the winter and spring months was unusually high in grade, and 50 per cent of 1t contained silver ID its native form. ID July while extending 6 slope, 6 mass of barren material vas encountered, IL pitched toward the hanging wall and crowded the ore into e wedge-shaped | volume This principally barren mass | was composed of porphery and when | first met with somewhat reseDbled 6 | dyke, which character was confirmed at | later period An uprsise through it | developed a new body of ore much of the | same general character as the ore met | with on the lower side of the dyke. As- says from the south end of this new | ground near the foot wall, gave from | 521 to S7lk ounces of silver per ton. and | from 63l to If per cent copper. Fsh- |
  ing minerals of the new ground which | has been sufficiently developed to ex- pose to view 6 body of ore 95 feet in its greatest length and S5 feet in width.
 This ore body winch, when taken to- gether with the ore on the l19 foot level Il discovered in the summer, "offers an ore body spproIimsting l93 feet iu height, which will take come three years or more | to exhaust with our 20 stamp dry crush | ing mill"
 The shaft station of the 300-foot level | has been retImbered and SD SIT winze | sunk through the body to the 250 foot level The ore passed through is of the same general character as that of the | level above, so far as explorations have determined. This level IS now in con dItion to be made producer.
 The $50 foot level believed to have been exhausted some years since is SUD- posed to contain this same bsrytOQusrtz- ose ore as mentioned having been met | with ID the level above, and will be ex- plored during tbe present year.
 On the abandonment of the 400 foot level year ago it was thought to have been exhausted with the exception of body of ore of limited extent lying with out the limits of the original level. The ore ID question IS high grade in its char. scter.
 In the 500 foot level reported as e1- hRusted 6 year ago, 8 number of rIob seams have been found outside the east limit of this level, and will be removed the coming year.
 During the first half of the past year, the 600 foot level was vigorously Operst. ed, but work was temporarily suspended before the extraction had been com pleted.
 The 700 foot level remains ss left two years ago, the ore having been exhaust ed with the exception of 8 small block of ground left intact in the proximity of the shaft and which ss yet is undis- turbed.
 The 800 foot level has furnished the chief supply of ore during the past year, and has been vigorously opersted. The of thIs level are 651ll5 feet. A prospect shaft ran 45 feet in 6 south erly direction, intersected several mar row seams of ore that averaged fifty ounces per ton, and upwards, but which were left for future development.
 By connection of tue main working of the mine with shaft No. 2 (Bilk shaf.). the ventilation of the mine was com pletely changed and IS now highly sstis factory. The drainage of the main work ings was diverted to this shaft and has since been handled through it.
 In order to operate the large body of ore lying above the sIll floor of the 250 foot level, independently of the main shaft, connection is to be made with shaft (Sorth King, over which 8 sub stsntIsl ssllows has been erected and @ new SAP single drum hosting engine placed in position and housed over. 4 finch Cornish lift pump will also be provided.
 "ro summarize, in addition to the 536 73I cubic feet of ground worked out ID the ore body, there have been 403 feet of old tunnelling remodeled, graded and timbered, 260 feet of new tunneling driven and 2l4 feet of vipze sunk with sn incline raise of l4S feet"
 The total amount of ore sent to the mills during the year was 31, ,190 toms.
 The quantity of water raised from the workings through the three shafts, wss 2rZ2O, ,355 gallons in excess of that of the previous year. The total amount raised was 1, 4,575,S ,S75 gallons.
