WILL FIND OUT F ESPERANzA
 IS STILL GOOD
0d Property Near Tucson Was Taken Over By Men Who Will Subject It to Test for Ore.

TUCSON. April 7.--The old Esper- anza patented miae. located about 50 miles southerly from Tucson, ana adjoining the Chesterfield mines on the south, in the Sierrita mountains in the Pima mining district is to be rSopened, and tested as to its merits. The Esperanza mine and mill site was located more than 90 years ago and patented about 25 years ago.
 In 1881 and 1882 it was purchased from Samuel Hughes and others by the Esperanza Mining company, com posed mostly of people living in Indi- ana and Ohio. Some local parties were interested, among whom was E. B. Gage. It was then worked and de veloped as silver mine, the ore ex- tracted being shipped to cusuom smclters. The ore was rich grade, carrying from 50 to 150 ounces in silver. also some gold, lead ana cup per. As depth was reached sulphide of copper came in, and below the 100 foot level the ore became so heavily impregnated with sulphur that il was difficult for the men to carry on oper- ations. In the lower workings a shot was put in which developed such rapid inflow of water that the min CTS had to leave their tools and every thing to escape drowning. It rose some 20 Feet in the shaft.
 In those days sulphide of copper was looked upon as refractory ore and there was heavy penalty at the smelters for it's treatment. This talk en in connection with water, discour- aged further operations of the mine and for several years it was aban- doned so far as work was concerned. When some parties took a lease on the property they extracted several car loads of ore which brought svou returns in silver Later a couple Of car loads were taken from the upper workings which also brought good returns; but the timbering in the cross cuts and drifts commenced rot ting and caused caving, which rel- dered the further working of the mines improbable without the ex- penditure of a large sum of money. bout year ago local parties secured an option from the eastern owners, and last November Captain c. T. Roberts, @ mining man, was taken out to examine the property. He was much pleased and pronounced it ont of the most promising in the entire district. A few days later he had Mir. Kemp, the mining expert of the c. & 4. people, join him in an examination of the property, and he agreed with Mr. Roberts as to the probable value of the property; conditions all being favorable for a1 unusually promising rich silver and copper property.
 They informed Hon. Frank Here ford, one of our leading mining law yers, who represented the eastern owners, of its probable value, and he proceeded to do some preliminary work, waich resulted in several gen tlemen joining MT. Hereford in the purchase and development of the old patented Esperanza. Among these are L.. w Powell, general manager of the c. & A; W. E. Kemp, mining ex per; Capt. c. T. Roberts, general manager of the l.. Zeckendo-f mining properties; Herbert Tenny. Dr. H. W. Fenner, John Talbot, Epes Randolph and L. Zeckendorf, who represent some of our best practical mining and business men.
 Capt Roberts is the superintendent of the development work and Wilt probably leave for the mine today and put on a good force CT men,
 A new shaft will be sunk directly west of the old one, with view of getting under the old workings. It will cost less than retimbering the old shaft, drifts, etc. Supt. Pike Of the Total Wreck, visited the proper ty a few days ago with Capt Rob erts, and expressed a like favorable opinion as those who formerly re ported on the value of the property.
