NORTHERN SONORA.
Rich Mines now in Course of De- velopment by American
 Capital.
Rem arkable Results of the Rusenta at cne Time Looked Upon as the Bonanza Mine of that Por-
 ton of the County.

sho siihSo Ol ILi iOuO "uiCu BlhcF promise of shortly becoming one of the richest gold producing sections of the Altar mining district of Sonora, Mexico. Like many others 1t has long lain dorm ant for want of capital and enterprise to push it ahead and until the spring of this year it was almost deserted. s nee then however a marked change has taken plsce entirely due to American money and energy as displayed by Gen. eral Naming of Tucson. Where but a few months back not team was to be seen for days at time on the roads. now a considerable numbers of wagons hauling wood for the stamp mills and supplies for the mines are to be met in every direction.
 Leaving Sassbe, where the Mexican custom house is situsted, the first evid- ence of this change is n1ticed iD the neighborhood of the Fl Groupo mill, twenty miles from the line. This is 8 ten stamp mill in course of erection for the treatment of the ores from the Groupo mines which have been opened up under the supervision of Mir. Blake.
 Fifteen miles further on the village of Fl Plomo Is reached and the sound of falling stamps IS heard. This comes from the ten stamp mill owned by Mr. Jackson and several Chicago friends who recently purchased the RusenIs mine which many years ago was looked upon as the bonanza mine of northern Sonora. In the short time that this mine and mill have been running, barely three months, the owners have taken out sufficient bullion to recoup them from for all the money spent in the purchase of the property and have in consequence become so favOrably impressed with the surrounding county tnat they have taken hold of several other mines.
 Their main mine the Rusenia is locat- ed in the mountain of that name and was worked down to de pth of between seventy-five and hundred feet by the Mexicans prior to the California gold rush of '49. It produced great deal of nigh hrade free milling ore which was packed ten mIlee over to the Zoni on burros and there worked m srast a. leaving behind many thousand tens of rich tailipgs. Thess tailings will short ly be re-worked by the cyanide process, the Mexic.p branch of the McArthur Forest Co.,, having commenced to erect 8 plant CD them Capable of breaking thirty tons day. At this rate it ie expected two years will be spent in dis posing of them.
 As was invariably the case with the mines the quartz from which could onl ' be worked in 8rastras. as soon as tn. ore became base, work had to be sue pended. In the change which too place however from free milling qua tz to pyritic ore the value in tbis instance did not lessen as 1t often does, but on the contrary, became higher aud at the present time the ore has an average oi S45 per ton. The velns are we'll defined, there are two on the mine which can bt aced twenty feet apart from the foot of one side of the mountain over the cone down to the base on the other sid, distance cf about & mile. On the eastern slope of the Rusenia mountain the ground belongs to the Chicago com pany and On the western slope to Don Ricardo Johnson, of Hermosill1, who |. now interesting capital to work hi. ground.
 The development work on the Ruseni, consists of two parallel tunr els one oi each vein respectively SIX hundred anC five hundred aud ten feet joined by | crosscut twenty feet iD length. On boIt veips the ore IS the same. A bluisi white quartz carrying argentiferous galeua and iron pyrites. The walls ar, granite. The veins vary from eigh inches to three feet ID width, contract ing to the former width and expanding tn the latter at regular intervals. |, the 600 foot tunnel there is body of ore twenty inches wide averaging Sl0U per ton. Ores running up to hundred dollars per ton are remitted at Ell Plomo the greater portion of their value ha being caught in the concentrates. Tn first class ore running from one hundred dollars upwards Is shipped 10 Denver, and smelter returns on the last carloso show a net profit, after charges for treat ment, freight on railroad and hauling have been deducted, slightly over | hundred dollars per ton. At the pres ent time fifteen men are employed ip the mine, but Tn a short while it is the intention of the owners to increase thai number and -nlsree their plant.
 About three miles distant is the Sar Manuel mine and numerous extensions of the same. This is strong we'll de lned vein five feet wide with cropping ten and fifteen feet high. Down to q depth of fifty or sixty feet considerable work has been done at different time by the Zepedas and the Serranos Ci Altar. As in the case of the Rusenif they suspended work ss soon as the or, changed from free milling to concentrat ing, but this mine is too god one t, long remain idle and will Tn all probabl Iity be worked by American capital be fore many months have elapsed. In the same district the Csmpans upon which ten stamp mill is being erected vii soon enter ths list of bullion producing properties, and near by Mir. O. E.. Guver of San Francisco, has erected & plant tC treat ten tons of gold ore per day ou [ vein of free milling quartz.
 Taken all together these enterprise made a vast difference in the appeRrsnc, of the surrounding county and Fl Plomc may certainly be looked forward t. producing ip the near future a consid erable addition to the output of tht precious metals in the Altar district Being nearer to Tucson than to sny other point of importance El Piomo ought to be good 6eld for the mer chants of this town and dnubtless will be if Nogales is not flowed to capture the market. At present Tucson bsf hae the advantage for it is within hun dred and twenty miles over a good wagon road. while Noesles is a hundred and eighty miles away; hnudred miles by wagon road from Fl Plomo to Ssnt Ana. and eighty miles by railroad thence to Nogales.
