BEGINS ACTUAL SHIPMENT TO
 SHELTER
Railroad to Denn Mine Finally
 Completed and Property = Takes Its Place As Shipper
 of Ore to Douglas,

The chief feature of the past week in mining circles in the Warren dis trict has been the actual shipment of ore from the Denn-Arizona to the smelters at Douglas, marking the en- trance of this property to the class of producers. The management of the Denn intends prosecuting development work with all speed at the various points where ore has been eIcoun- tered, but more especially in the stopes on the HOO level. as it is be- lieved that a body of considerable pro- portions has been found there.
 At the Copper Queen and Calumet & Arizona properties there has been little of interest, the only operations out of the ordinary being the prose cution of improvements which have been under way for some time past. At the Shattuck-Arizona the same con dition prevails.
 The general outlook, no small feat ure of which is the proposed enlarge ment of the output of the Superior & Pittsburg, tends to indicate material increase in the production of copper within a short time.
 At the various small properties throughout the district operations are being carried forward as rapidly as possible and favorable results in sev- eral instances have been obtained.
 The following is an extract from the report of s. J. Beahan, special representative of Hayden, Stone & Co. of New York, who recently made an exhaustive investigation of the devel- opment work which has been prescott. ed in the Warren district:
 Superior & Pittsburg.
 August fl, 1907.
 The Superior & Pittsburg is about to profit from its enormous outlay for development and construction work for the past two years while in the fact that all of it's shafts are now commanding the ore bodies. is assur. ance that immediate returns in the shape of broadened reserves will at tend future underground expenditures, The fifth furnace of the Calumet & Arizona is complete in every re- spect and will go into commission September 1st, in the treatment of Superior & Pittsburg ores, when the monthly output of the latter will be increased from 100000 to 100000 pounds. which will probably reflect a nUT1lldl SCdlG Ol OpeIdllOuS uuLll bIlS sixth furnace is in readiness
 The great bulk of the Superior & Pittsburg output has thus far come ffom the Cole shaft, opened to the 1450 foot level, at which depth the greatest thus attained in the BisDee district, drifting has just been com menced.
 The biggest developments are On 7nnn I1nnn fOpf Iavp1S while at the 1900 the deposit has only re gently been disclosed. Ore is being extracted at the various levels from the 800 to the HOO, inclusive. The Sunnyside claim, tributary to .thi! shaft, contains one of the biggest de veloped ore bodies in the camp. Tht 300 foot level is disclosing gooC average grade of ore while at tho 800 foot level a big stope is beini drawn upon.
 With the starting of the fifth fur mace the daily output from this sourc' will be increased from 400 to 800 tons though a much larger tonnage coult be provided, were 1t necessary.
 In common with number of others the Superior & Pittsburg has wisel taken advantage of the high price o of the metal to the extent of extract ing such grades of ore as would 1T sure creditable returns. This has pai ticular reference to the operations the Cole shaft from which the laN grade sufphides have also been use extensively for fluxing purposes. | consequence of this policy the ric ore bodies still remain practically 1T tact with the result that the compan is in position to materially offset tn loss of earnings following the declin in the metal market.
 The Junction shaft is opened to tn 1900 foot level. with development work on a broad scale under way a the 900 and 1000, while at the no the ore body has only recently bee Intercepted The bulk of the pre-; ent monthly output of about 1900 ton is being secured from the 900 foo level. where extensive reserves ar blocked out. With the blowing in the new furnace the output this shaft will be increased 100 tons daily. A new and pow erful pump has just been receive at this shaft for installation at tn 1000 foot level, the purpose being make the Junction, in addition to il regular service. the drain shaft fC the openings commanded by the Hoa son and Briggs. With this end view a drift is now being extende from the 120o foot level of the Jun ton to the Briggs shaft. now opene to a depth corresponding with th HOO foot level of the former. Wit the completion of this drift, raisin from the 1900 to the HOO foot lev of the Briggs shaft will be cor menced.
 Crosscutting at the B.lSss shaft hi commenced at the HOO foot lev which is under the big leached o bodies developed sn the i0c0 Il which reason the -iadi cations poil to the opening of good stop'ng eroun
 A feature of the recent operauOi is to be found in the Ia yorable dew opments at the Hoasso1 shaft, which sinking has been conducted a depth of about 1850 feet, equal the 1900 foot level depth of the Jur
