Mines of Mayer District

(By F. w. Bower)
 MAYER, AriZ.. April 29.-Ten feet of shipping ore has been encountered in the west crosscut at the 500-foot level in the Arizona Copper mine, locally known as the Pentland mine. This sounds like a simple statement but in reality, it is without doubt the most important ore discovery made in the Mayer district for many a day. The Arizona Copper and Min ing corporation was started locally about year ago on group of min ing claims owned by. F. B. Pentland, of this place. The first stock was subscribed for in Mayer. It was later financed in the east to the extent of about s100,00O
 The company has done actual min ing. A two compartment shaft was put down to the 500-foot level which depth it reachel last week. Cross cutting was commenced east and west the expectation being that ore would be found on each side of the shaft. The first vein to be encountered came in about 30 feet west of the shaft The vein so far has been cut through for ten feet showing an excellent grade of smelling ore in copper and silver. There is reason to believe that the vein will be much wider. The ore occurs in the schist, the copper values being in the form of | chalcopyrite which is closely dissemin- ated in the schist. Mining men who have examined the strike are particu- larly well pleased with the fineness of the grain of the ore.
 | A meeting of the directors of the company has been called to consider whether to continue the shaft 50t feet deeper to the 1,000-foot level, o1 to explore the present 500foot leve first.
 No strike of ore in the Mayer dis trict has had such lifting" effec for many months as this PentlanC strike. Considerable of the stocl is held locally and everybody is hold ing onto it at double the price O last week before the strike was made They are expecting to hear something sensational before the width of tht vein is fully determined. Then, th' mine is so close to Mayer, about twt miles northwest, that it means ; payroll that will come directly t( the town. Most of the miners liv, 1 in Mayer and go back and forth tt work each day.
 Outside of the worth of the strike to the stockholders of the compan. and it's effect on the business O Mayer, it means a great deal to thu district for the mine is located in al 1 entirely new camp, off from th' Blue Boil and Binghamton strikes The mine adjoins the old Hackberr! mine on the north and is about on' mile south of the old Boggs mine The ore system runs parallel to tn I Blue Boil belt, about one mile wes and it can be easily traced north ward through the Iron Queen, Boggs Swindler, Lone Pine and the propert, that has just been taken over by tn Humboldt Consolidated Copper com pany. No properties have been de veloped to the south of the Pentlan, mine, to any great extent, althoug the ground is all staked for severa miles in that direction.
 The Pentland strike has agai 1 proven up the Yavapai district. Tin depth of the shaft 800 feet, is suffI cient to find permanent ore bodies a has been proven in the Blue Bel Binghamton and other deep mines 0 the district. Another vein of ore i known to exist east of the shaft, an it is expected to be encountered a any time.
 This mine undoubtedly has a grea future. It is well managed, and re suits have come just about as planne at the beginning of things a yea ago. There need be no experiment either in the mining of the ore Q in the milling for there are now i the Mayer district a number of sue cesses on the same class of or, There is as. yet no talk of the com pany putting it's own mill at the min, The most important thing, in tn . planning by the company is to "fin 1 mine" first which is considere good business.
 !. Mayer is soon to have a custor ore plant. The Mayer Ore Purchasin company has leased the old Ora
 Eagle mill mile below town an |. in few days will be ready to bu custom ore. The capacity will | about 100 tons for the oil flotatio
 process and 60 tons coarse concen
 tration. Later on, the company wi
 be ready to handle oxidized coppe
 ore in the teaching department. Th
 mill is in charge of H. A. Wagne
 who was the original inventor of th
 electrolitic process for which the mi
 was built. The whole plant is no under lease to the Mayer Ore Pur chasing company.
 A custom mill has been great needed in the Mayer district. An
 sized ore shipment will be handle, i from a carload to a sack It wi make it possible for the small min owner to find an outlet for his or
 in small lots.
 The company also acts as purchas
 ing agent for ores which will I : sampled and shipped to the outsid
 reduction works. A complete samp
