most m circle, put tne leuBe WAS not followed.
 The Leopard is the eastern and the Reflector the western extension of the Commodore.
 The Searle mlne, not far off, has a broad cut run in, showing the ledge to be l6 feet wide, and there are two other openings at the south center Cf the claim, showing carbonate ore giy- ing assays as high as $50
 Pilot, close by the above, IS only prospect SO far, but shows black sul- phuIet ore The ledge measures three feet and a halt between the walls.
 Herman, adjacent. shows large croppings of ore similar to that Of the Pilot.
 Ella runs east and west, and shows large ledge. l. is the extension Of the Silver Wing. and shows the same character of ore.
 Silver Wing has a cut of about 10 feet, showing the ledge al the bottom 26 inches wide. Twenty eight hun dred pounds of ore from this mine milied in Tucson returned about SlOO per ion. The ore contains malleable sulphurets and sulphurets, also silver glance. It has 8 well-detned foot wall and a talcose casing.
 The San Jose mine is situated about a quarter of a mile oyer the Sonora border, four miles southwest of the Warsaw mill. It was discovered about 15 months ago, and great deal of very rich ore has been extracted which was worked at Derre's mill al Arivaca. The ore seems to exist as a stockwork or network of veins. The formation is porphyretic slate and granite. Five of the veins have been somewhat developed. There Is shaft 2S feet deep which shows rich ore on both sides. A tunnel has been run in one vein 32 feet, and there are several cuts and Mexican workings. At present no work is being done. There are about five tons of ore on the dun packed in bags which IS high grade and will mill upwards of S2OO per ton, as well as a very much larger quantity of low grade ore going S25 10 $50. Most of the ore is free-mlll- ing, consisting of horn silver and de- composed gray copper and black sui- phuTets. The main vein is traceable about one mile oyer the hill, showing the same kind of ore. Assays made from the ore run from $50 as high as S10, 900 per ton, picked specimens, and altogether l am informed this is the richest ore yet discovered Tn the district.
 One assay made Of 12 pounds of ore gave SlS2 per ton. The ore was talk GU haphazard from one of the bags.
 Excelsior is one mile and a half from the Warsaw mill. This prospect has a ledge over 50 feet wide on the surface, and although much develop ment has not been done, will no doubt prove a valuable property.
 l must not omit 10 mention the Orc Blanco mine, from which the district takes it's name. There is an open cut for 70 feet along the vein and from 30 40 feet in depth, from which the ore has been extracted when worked by Mexicans years ago and the ruins of g. arrss,ras testify the great amount of work that was accomplished. The proved length of this ore body Is as EIbtA a huAAS Gr aL JOA9 "oAN7.
 The extension of the old Orc Blanco mine IS, l hear, valuable property. II belongs to Parson Mills and Broth CT, and has 30 foot shaft, showing 6 good body of ore.
 On the Western or Yellowstone mineral belt 1 visited the Old Ostrich and Yellow Jacket mines. The old Ostrich mine is about two miles from Gro Blanco. It has main shaft 60 feet deep, but which has now caved in, the mine has ret been regularly worked for two years. A good deal of ore has been worked and some av- eraged as high as $60 per ton in gold.
 Messrs. Cook & Co. report their re- turns after paying for milling al Sl950 per ton on what ore they had had worked at the old Ostrich mill. The quartz contains good deal of free gold. The vein runs northwest and southeast and the mine is the property of Bartlett, Hewitt & Co.
 Yellow Jacket gold mine has shaft of about 130 feet, with two levels at 40 and 100 feet. The first level is cut along the ledge and cross cut, showing the ledge 10 be 2o feet broad. A large chamber has been stopped out about 50 feet high, but cave taking place most of it Is now filled up. Many assays have been taken of this mine, and the ore on the dump goes S24 in gold, whilst a fair average of the ledge taken with view 10 purchase, gave somewhat over S22. Even at this, this is val uable property, and if the mine is taken hold of and worked as it is sup posed it will be by San Francisco parties, a good return may without doubt be looked for.
 The Spanish Galleen mine IS close to the old Commodore. l hear it may not be long before work is commenced on #.
 The Katie group, consisting of the Katie, Queen Emma and Princess Sarah, are not far from the San Jose. They are promising prospects, and have had some preliminary work done on them. A. LANG
