LOCAL MINES AND MINING.
IMPROVEMENTS AT THE HUMBOLDT.

. IMPROVEMENT AT THE HUMBOLDT.
 The Arizona Copper company are
 DOw arranging to equip the Hum 0oldt. one Of their best developed and
 largest producing properties, with
 electric haulage and electric lights.
 and with this eBd ia yeiE Chief Elec-
 ,rician Cox, with & corps of Assistants.
 is nOw at work putting ia the wires
 aud making the connections. The
 power will be supplied from the Long,
 fellow concentrating plant. aud ca Jled . to the mine at NOrcuCl. distance Of one mile. 4 3O-h ?. electric lOcOmO-
 tive will be used for hauling the cars, which will have a capacity of tons each, banliiuy srJgt @6 tons to the
 trip. There will Da aDOLt ;"O miles
 Of track in the mlue= equipped for
 electric haulagc, and She mines will
 also Oe lit with IucaaQe-c-ut lamps.
 The lower levels will not be equipped
 for electric haulage for some time get.
 a- the great bulk of the ore i- now
 coming from the upper levels. The
 mine is now producing about 500 tons
 Of ore per day, which requires x
 DIles and l6 men 10 bring II tD the
 surface and dump it into the ore bins. . -NtdIlN d-f tI tIlo t' if-ll-f " III b- dOne away with bv electrical hau,age.
 and bes de7 that the ore vii be hauled
 in one shift.
 A tunnel has been driven through Copper mountain on the Humboldt
 workings, after which the track
 crosses the gulch and connects with
 tunnel on the Clay mine, which has
 been driveu in several hundred feet.
 \ plant for air drills is now being put
 in at the lace of the Clay tunnel.
 which will be used in driving this sun nel through the mountain. when il will come out on the other side at about the head Of the Queen incline.
 When this tunnel Is completed the ores from the Queen mine will be brought out ever the trcllv line and through these tunnels tO the mouth Of the Humboldt tunnel al Morenci. and conveyed from there to thc Longfeilow cOucentratOr by the railroad. The tunnel through the Clay mine will also ba used for operating thc Cd"a-cp and other mines on the same mUun- tain on which the Clay mi ue is s.tu- ;.tcd.
 Arrangements are also being made in tue guIch between the two tunnels 10 desulphuriie thc heavy sulphide ores which are now coming from the Carasco mine.
 4 new and large hoistinr plant is also being erected oh the Humboldt for operating is lower levels. which have now reached d depth Of +1O feet from the mouth Of the tJnnsi. through which the great bulk o7 the ores are uOw handled.
 Work ls progressing rapidly on a system of dam, for -tC.,ug the tail ing5 from the \. C. %concentratOr. which will b, in opera on ta 3 short time The taiiiug, will E. dried, then hauled by cars back tp fln mines and used for filling the | workings This will do away with F. annoyance of the tailings cominga down Chase creek.
 A new hoi-ting rig is tl-o being ar ranged for the YayapaS which will soon be in commission.
 The work of opening slp the new LongfelIow' at greater tep,l is pro- 9ressing fa"OrabIv, uaw{evels having been run much lower q svn the noun tain. which are being connected by the older workings abovcf A nsw tun- mel i, also beinT driven (I from Chase creek, which in time, rssrhaps year or moro will b. coAncc:eI with the LOngIellOw workings, at2DrGing u new outlet for the ores. duiNg away with the hoi,tiug plant and also opening the mine al great depth.'
 Arrangements arc being: made every where to handle an incr,Ei-ed tonnage, l and at less expense Tut managcme i- using every effort t0 .cheap.n the 1 cost Of mining and bal: Hing Ot the ores, and ere many mOtths what l. known as the Longfellow group. which . included q number of prt)mjnent pro- iIccrs, will be producing and hand . ling their ores for less expense than . any other company in the west.
 From A. Lpfave, who has number 1 of claims in the new district near 1 Granville, the ERA learn, that the ! miners held meeting there last week { md organized a noT district, tO be ! known aS Gold Hill. The district . starts from the mouth of Silver creek { and run, west to the toll road on Chase . creek. thcn'e ten miles north, fen . miles east, ten miles t1 the san Fran . cisco river aud down the river tO the mouth of Silver creek. the place of beginning. The new district takes d part oi the old Granville district and also part of the Greeu!ac district. raw ford and Await. who have bond DO the Frye and kiu7ev claims have had the property surveyed and monu- ucnted and have conmeucoo dcvciop- :. men, work. S1 far a- work has been lone the property i~ making a tile ,tOwiug Mir. Crawford estimates that from varjOu- samples, the leads { will average about one ounce gold, and . cad and si.vc" sufficient to bring the general average up to about S26 per ton. The veins are usually found in the contact between lime and ouartzitc. md are very promising. There are also u number of faults which have formed blanket veins, which can be 'augh. by going down through the nalpai~. There are number Df inc blow-out9 through tpe mliuBis which indicate that the country j. 'Overed ny an overflow, and 1t may )e that many good properties will b, truck by sinking through the nal lais, as was the case at Tonopah.
 Dick Lakenau ot Clifton and his brother k | Lakcrau of New York, who have been partners in valuable group of Ciain, iu the Copper m1Gl- ain district near Eagle river, have made a division of the property. Dick gets d. his part the Campbell and stevens mines, ani the water right which consists 0f a large spring which 'iseS at the base of .argc malpais mountain west ot Eagle river. and . 'au be conveyed by gravity tO the hines for milling purposes. Dick is LOW negotiating with the owners of -Iiffou H.iphr- fo pif,ss inc ,ya or. IA,
