 Different Districts.

l pocG mas been brought CO llSnU
 by Messrs. Ismond, Mccall and Stafford. Surface exposures show good silver values and the indications are that these gen. tlemen have located an excellent silver property.
 One very interesting and pc culiar feature is that the gangue or vein filling is largely barite (barium sulphate) which appar- ently "carries" the silver values. This means that it will pay any one who has barite. deposit upon their property to investi- gate it for silver possibilities.
 A number of prominent min ing companies were represented in this district this week, among famous Tigre Mining Company of Sonora, Mexico.
 | At this time there is a demand for silver properties or good silver prospects. The silver content of ores in this district | has been largely overlooked: lead and copper has been sought after, and when these lead or copper ores had silver content it was not appreciated. Now, with the price of silver high and lead and copper low every one should seriously prospect for silver not only for new ore bodies, but old stopes and workings should be explored for their silver pos abilities.
 A. F. Gross, one of the large northern iron mining operators, recently in the district wires that he is now ready to develop two of the properties examined by his engineer. He will soon start work upon the American Boy property. owned by Messrs. Clarke, Petersen and Scheler, and the Deep Down property, owned by John Costello.
 Gray Brothers have given a lease to Ricardo Zazueta and Aurena Rivera on the Roanoke and Papago claims of the Col licello gro6p. On the former claim a vein was recently un covered which is reported to assay 1.6 ounces in gold, 53 ounces silver and 65.12 per cent lead. The Papago is a copper, gold'and silver proposition. The leasers are now sinking winze in the tunnel on the Roanoke and expect soon to be shipping O1e regularly.
 The Collicello group adjoins the Arizona European property on the south, and is only mile from the Three R mine. w. D. Gray, one of the owners of this property, is enthusiastic over recent discoveries and is sure it will soon develop into a real mine.
 Frank Reichert, in from the Alto district Monday, makes the statement that Mckinley and Smith of the Mckinley Mining Company are busy with develop ment work, at present being engaged in driving the lower tunnel on the Trudy and expect to strike the main vein within the next 10 feet. This company has just completed 100 feet of tunnel and shortly expect to contract for a 2OO-foot extension on the same work. The Trudy is a silver property. Develop ment work is also going forward on the Bland, owned by the same company. "Black Jack" Garden is manager of the Mckinley in tereStS.
 MT. Reichert also states the amp is anxiously awaiting news from the Grund Brothers of St. | Louis, who are expected to take over all of the Baca Float in terests. If this deal is consum- mated it will mean big things for the Alto district.
 Bracey Curtis, president of the First National Bank of Nogales, who is interested with B. E. Bethel in the Chief property. adjoining the famous Worlds Fair, in company with MT. Be thel visited the property Sunday last. A decision was reached to at once employ a force of men and begin development work on the Chief on quite an extensive scale. It is the inJen tiOn of those interested in this property to sink a deep shaft. A. H. Glidewell will be in charge of tho work
