 Other Properties.

Wickenburg. Ariz., Nov. 2.-(Special correspondence to The Republican)-As is usual at this time of the year on ac- count of the assessment work being done on the numerous prospects, quite a number of important discoveries of mineral are being reported by mining men coming in from the hills around Wickenburg In addition 10 this. sev- eral of the large properties are either again being developed or preparations are being made for the beginning of active development work so that the coming winter promises to be the live Hest one in the history of the camp.
 About the most important strike lately was the cutting of the big ledge on the 300 foot level in the well known O'Brien mine. northeast of town. in the Black Rock district. For several months past Mir. O'Brien has been working a force of from twenty to- thirty men and the crosscutting of the ledge at this depth is likely to have an important bearing on the future of the camp. The ledge is over 25 feet in thickness and rich in iron sulphides, carrying exceptionally good values in gold. As is usual in a ledge of this
 
 very rich in gold, some as high as several hundred dollars. while the en- tire body carries sufficient gold values to make it profitable milling. The ledge has already been opened up on the 100 and 20O-foot levels and a ten stamp mill on the property has been used to prove that the mine will un- doubtedly prove a big money-maker for its owners. It is not proba ble that the cres will be worked, however. until the stamp capacity has been increased. probably to 40 or more stamps. Mean time the opening up of the ore body will be continued with a full force of three shifts.
 The five stamp test mill recently in- stalled at the Orc Grande. has been completed and a short run made to get everything in smooth running order preparatory to the final test. About thirty-hour run was made and the mill worked entirely satisfactory. Ore was taken prOmiseuously from all over the dump ard the rlates saved over s20 a ton. making almost a complete saving of all the contained values. At present the company is working three shifts in the bottom of the shaft, sink ing to obtain a greater reserve supply bA water HUI AA4E SElAEl al ACSl OA lilE mine. which will be made upon the arrival of eastern members of the company. expected this month It is understood on good authority that the company will at once proceed with the erection of the contemplated 1OO-stamp mill If the test proves the ore to av- craze & a ton, a fact which is gener- ally more than conceded by all who have worked in or are acquainted with the property General Manager George B. Upton is in charge of the property.
 4 number of cars of machinery have lately been received by the Black Rock Mining Co. operating what is generally known as the Jim Murphy property. Several engines and hoists are among the outfit and have been taken to the mine. preparatory to deep sinking. Commodious buildings have been erected during the summer and active work will proceed during the winter. Samples of the ore now being brought to town show it to be rich in sulphides and salena, said to carry high gold values. and they undoubted- ly do. as the oxidized surface ores were rich in free gold and were arras- tired for slime time. West Superior. Wis. people are promoting the com pany and J. K. Murphy is ably con- ducting things at this end.
 The Orc Grande Exploration & De- velOpment O.. operating the Powell group. are now down about 160 feet below the surface and continuing sink ing in the winze from the end of the crosscut tunnel run this summer. Since getting below water level the ore has largely changed to sulphides and galena. carrying good gold and silver values. A little more than. six feet of pay ore satisfies the owners that they have one of the best proper ties in this section. George Sanders. superintendent of the Vulture, visited the mine last week in company with other mining men and sampled the ledge. After making a cyanide test, he reports the ore to average S1I a ten in Ngold and almost a complete saving by the cyanide method. This will be good news to the many Phoenix people who are interested in the company.
