WEEKLY MINING REVIEW.
PIMA COUNTY.

. Wnlch yleIu Elcn ore m limited quanu-
 ties, will be worked in a legitimate way
 when more IS known about the tune
 when the Tucson smelter will be ready
 to begin operations.
 The Canyon de Gro district may be relied upon for a considerable quantity
 of low grade ore. The district imme-
 diately west of Tucson, only few miles
 distant, contains numerous small ledges
 of free ore and of high grade, which may , be mixed with those Of Canyon de Gro , and worked to good advantage. There
 are a number of good prospects in the . Sierritas which yield free ore in limited , quantities. The same may be said of , the mines in Owl Head district Low P grade ores in considerable quantities
 may be had from the north side of the santa Ritas. The rich ores of the Casa
 Grande mines and the QuijotOas will also be tributary to tho Tucson smelter.
 Copper ores may be had from the
 Santa RItas. Old Hat, Silver Bell, and
 the Sierritas. The prospect for sup plying smelters with both silver and cop per ores are very good, and if mlne own CTS and prospecters in the vicinity of Tucson do their duty there will be no scarcity of ore to run both smelters.
 We shall endeavor to enter into ds- tailed report of mines in this immediate vicinity, at an early date, that may be relied upon for furnishing ore at this point. and from facts already in our pos. session We believe the number and character of the mines will prove far better than are generally believed to ex- ist in this locality.
 CACHIsE COUNTY.
 | Contention. - Permanent work has been totaley suspended in the Conten- tion until the stone work is completed and the pumps are put in place. The late accident at the mill will be repaired in 8 week and the stamps will begin to work
 Grand Central About l00 tons of ore | are being shipped to the mill daily. The stopes in the northern portion of the mize are still being drawn upon to sup ply this quantity, but their exhaustion seems as far of as ever, judging from their Uuvarying yield. The drifts in the | s1Ctherly end of the mine are beng proceeded with. and the results on some Of the levels are encouraging, whilst ID l others they show varying prospects. SIdney.-Work on this mine recom- meuced three days ago, and all hands are busy tlmbering the north shaft, which is now down 56 feet, and is sunk on the ledge. Superintendent A. Mitchell speaks in the most sanguiDe terms of the future of this property, and notwithstanding the many difficult ties he has met with, we are glad to again put his mine on the active list.
 Rsttlesnake and Mammoth.-Worko on these properties proceeds rapidly. On the 1GO-foot level connection has just been made between the working shafts of each mine by drift 400 feet in length, and a stOpe on the 160-fOot level has been started to work on the large ore body there encountered. East of for SD s--oth shaft are two levels, and whims at present are raising a5Caf twelve tons daily, but this will be great Iy increased before long. The width Of the ore body referred to varies from four to seven feet, and the ore is free milling.
 Tombstone M. and M. Co. Tho West Side mine continues to supply the bulk of the ore that keeps the mill going, and from all accounts ia going to prove tine most enduring of this companys properties. The ore is richer in gold than either the Toughnut or Good enough, whilst the horn silver makes the average assay of the ore very high
 Ingersoll Con.-An increased force of men is being employed here, and the hoisting of larger quantities of good ore is thereby augmented. There IS plenty of virgin ground to work upon. The drift on the 4OO-foot level is being pushed ahead.
 LUcksure.-StopIng has again com menced in some of the levels of this mine. Prospecting also goes forward with very satisfactory results. The ore is principally manganese, and the aver age value about SsO per ton. The ledge dips into the hlll, and shows an increased width in bottom of shaft.
 Pronpter Work progressing very satisfactorily. Connection has been made between shafts No. and 3. Now engaged in cutting ont station in No. haft. Will commence Monday taking out ore. West drift going ahead; now in 20 feet. Vein looking we'll
 Eucalyptus The shaft is down no feet, and drifting to the north and south have been started The indications are favorable
 Atlantic, at Bisbee The work in the tunnel at the east end of this mine pro- seeds at the rate of about fifteen feet per week. We arc indebted to the Re- publican for the above summarary of ot mining news from Cachise county.
 TAvAPn COUNTY. Pine Springs.-About 10 tons of se- lected ore have been shipped from the above mines to Pueblo, Col. It IS be- lieyed the owners will realize from s5O,- OlO to sl00OOO from the shipment Do50ris.- Mr. Craig, superintenent of this mine states that he has about eight inches of ore at the end of the 7OO-foot | tunnel, worth from three to S6OOO to the ton. Nineteen men are at work on | the mine.
 FINAL AND CHA COUNTIES.
 Blue Bird.-This property. in the Mar tiuez Canyon, IS developing finely. The vein is capped with quartz, showing | caiena. They have in 9 20-foot cross cut a I2-foot seam of quartz carrying ! grey carbonate and galena- The walls are we'll defined and l2 feet apart. They have drifted in 12 feet in solid ore. The Monarch of the Sea-Fine ore is being raised from the double shaft. Tho | tunnel IS in 275 feet, showing metal all | the way. The owners are full Of enthu- siasrn, and the prospects arc encourag- inr. The company is building a fine road which Is nearly completed to the King mine, which will do away with the ! necessity oi packing timbers to the mine
