YUMA COUNTIES BONANZA.
S22. 900 Per Ton in Silver.

S22.OOO Per Ton in Silver.
 Nearly two months ago it was reported on the streets of Yuma that new find had been made, in Silver District, forty miles nearly due north from here, and four or five miles east of the Colorado river, of immense lodges of ore rich in silver. The new find was too near home, and our people have had mining experi- ence enough to make them very cold nosed on new discoveries. Gradually, however, specimens of rock began to come in. which rivalled in appearance those found in Globe District. Assays made of them gave the extraordinary yields of from $500 to S22,000 in silver per ton. These attracted attention of our veterans, who went up to Silver District and whose reports have received a credence here that was denied to those of strangers. The descriptions they give are simply marvellous. MT. Julius Sebeck, a graduate of Freiberg and miner Ill Arizona since 1S64 says that in Silver District is now opened new page in the history of mine- ralogy. He has made numerous assays of it's ores, with results ranging from hun- The largest and richest veins found ap- pear to lie in basin few miles long and a couple of miles wide, and bounded by mountains of secondary granite. The form atlon in which the ores occur has been so differently described that it is probably ] of a composite character. MT. Warren | Hammond was the discoverer of this group of mines, and is associated with Messrs Burnham, Rohwer, and Ringwald in a number of locations. He has four | teen tons of the ore at Norton's lanGing; waiting for the steamboat Repeated assays have led him to expect to sell this lot at San Francisco for money enough to open and develop his property. It was taken from drift six feet in depth.
 But the mine now recognized as the most remarkable in the District is that of Mir. Thomas Hughes, comprising the Pacific and Black Rock, adjoining claims, covering 5000 feet of ground. This is described as contact vein with granite foot-wall, and hanging g-wall of talcose and schistose slates. Its width is im- mense, but not yet determined. It runs N. W. and s. E., pitching to the East; at an angle of about 45 degrees. The hang ing wall has worn away, and the ledge is left lying against the hill, exposed to view for long distances, and to heights varying from a few to hundred feet. Nature has thus exposed for extraction more ere than could have been brought to light at an expenditure of S1O0,OOO. Immense bould- CTS of rich ore have rolled down from the ledge, and lie along the base Of the hill,- ready to be broken up, sacked and ship ped to San Francisco for sale. It is said that several hundred tons of ore can be selected from these boulders that will go over $500 per ton. Mr. Hughes offers to bet 5000 that he will ship S200,000 worth of ore to San Francisco by the first of next July. Fine assays and big prospects are reported from many other claimsj any of which would attract attention any where.
 It IS matter of surprise that these mines were not located and worked years and years ago. The explanation is easy. Early prospectors here knew nothing about silver and searched chiefly for gold Since prcspectors learned to recognize such croppings as were trotted over for years, but lately located in the Globe, Peck and Silver King mines, Yuma County has scarcely been prOspected at all by anybody. Some of the croppings of Silver District are covered with thin cruSts Of iron ore, assaying but trifie in silver, and atfording no indication of their value below. Col. SniYely was there tif- teen years ago and made some locations3 ] but he had no idea of their value. Even now old prOspectOrs pass by great bould- CTS in Silver District, not recognizing them as rich ore under their oxidized sur- faces until some older resident breaks one open for him.
 These new bonanzas lie within five miles of a steamboat landing. and within easy connection by water with the rail road here at Yuma. Their development will be cores pondingly rapid.
