A SONORA BONANZA.
Description of the Nina Maria Eins. Rerrao-
 s.lio District

Friday we were shown a report b, a competent mining expert upon wha promises to be one of the richest minei in Sonora-the Nina Maria mine. Thi property is located in the La Poso mount aims, 90 miles east of Guaymas and 10; miles southwest of HermosilIo, and & miles fIom the railroad and in the Her nosillo Mining District. It is easy o access and can be driven to with a wag on. The mine IS 2,i00 feet long by CO feet wide and the ieige rans east ana west. The eastern cad is crossed by an arroyo from which s cut has been run in on the ledge fifteen feet, exposing the face of the ledge ten feet in width to 3 depth of thiry feet. From this point i. has been cut out around on the foot wall exposing enc side Oi the ore body for twenty-five feet. At the bottom of this cut, which Is thirty feet deep, a shaft has been sunk twenty feet in depsh, thus exposing the vein to depth of fifty feet.
 Samples of ore were taken from the face of the ledge across the ten feet and one sample yielded at the mint in Hermosillo S22S in silver and another sample assayed in this city showed s12S.S3. In the bottom of the shaft, after cutting through morse" which carried between 80 and $40 to the ton, a body of ore was struck which carried notive silver, but as that was not sui ficlently exposed none of the ore was used in sampling. Clear across the whole ten-foot face of the ledge and along the twenty-ive-fOot cut on the foot-wall the ore is full of horn silver. The walls at this point are perfect and clearly defined.
 The ledge dips to the north about ten degrees and crops out all along the claim.
 Two hundred yards from the cut and shaft above described there is a blow out of pay ore forty feet in width. This body of ore shows considerable galena.
 About fifty yards further along the ledge is another blowout sixty feet wide.
 Prospect work has been done all along the ledge, showing good ore
 At the west end Is a siI-fOOt shaft, SllONlue tilt NdllS tl tue NClu dl lildl point twelve feet apart.
 The ore Is in quartzite and is mostly free milling, though the galena in the forty-foot blowout indicates the pres enoe of large body of smelting ore.
 There is plenty of wood and water within 200 yards of the mine. The Santa Maria river furnishes an abundant sup ply of water large portion of the year, and there IS, besides, large perennial spring at which 300 head of cattle are watered daily, and there is an old well by some arrastras which were formerly used by the Mexicans in working the rich ore they had gophered out of this mine. There are traditions of ore taken from this mine worth dollar pound.
 From the description given of the property 1t must he valuable, and cer- tainly its location contiguous to wood and water, and within fifty-five miles of the railroad, makes It well situated for paying operation.
 After carSful inspection of this prop erty, Major J. W. Olds, of this city has bonded. 1t and has gone to Chicago, where he formerly resided, to place the property. There ought to be ready market for such property as the Nina Maria mine.
 We know the Major to be perfectly reliable gentleman. and he understands the value of mining properties.
