With its certainly bright future this article has no need 10 deal. for the present facts, expressed without the least e1aggera- tion are sufficient to convey good idea of the merits of the properties and are, in truth all that can be said of them, for no one can tell what lies an inch below the deepest exploration of any mine. The accompanying map of a portion of the Casa Grande district will convey an idea of the location of the mining claims mentioned in this article, and to which reference is made in describing them. They are classified in groups according tn the metal found in the ore, the silver iniDes occupying the extreme northwest corner of the map being t, rmed frr con venience. group Nc. 1; the gold and silver mines, group No. 2; tho silver and cad mines, group No. 3; the gold mines, group No. 4, aud the copper mines, group No. 5.
 GROUP NO. l.
 Mineral King. This lies almost due horth of the Orizaba. It has a shaft 100 feet deep with drifts that cut occasiona bodies of orc. An incline connects with the shafts at 80 feet. Ore has bee, 'hipped from this property, but it was found to be unprohtable as 1t is too low grade. The ore bodies are large and should be worked at or near the mine. Several small shafts have been sunk on various parts of the claim. Severa' other adjacent locations have little de- velopment work, but all show evidences Df existence of similar ore bodies. These claims are located northeast and south vest.
 The Rambler. This lies to the south across wash and the ledge runs from the northwest to the southeast. It Is owned by Chas. R. Peterson and John Aron. But little development work las been done and it's value has not been demonstrated.
 Little Alice. .--Thls south extension Of the Rambler has & very larpe body of ow grade ore. IR few places very ich ore was taken out and shipped with satisfactory results. The main shaft on the northern end, is down 60 feet. tn, edge dipping to the east. In one shaft, tt depth of 15 feet, sand carbonates were encountered that were taken out without the necessity of blasting, as they could be easily shoveled up.
 The Orizaba group were discovered and locased by Mir. John Kron Tn the fall If 1880 and since that time he has lived and made his home upon them, staying by them through thick and thin, at one time being the only man in the district. The | formation at the mines while being iden- tical with that of the others in the dis- trict, dips in the opposite direction, l. e. north east, the up lifting and tilting of the strata by subterranean forces is shown by the numerous dykes and beds of igneous porphyry that during the dis turbance have been ejected through the breaks and faults thus formed. At the first glance the veins appear to be in quartzite but an examination shows that the same alternate stratifcation of quart xite and lime resting upon shale con- mon to the district is here, the upper layer of limestone having almost entirely disappeared it being somewhat dolomit- ic, the erosion has taken place much quicker. As the quartzite strata in the district varies in thickness from 90 to 12O feet and the main shaft on the vein has reached to depth of 100, it is plain | that in sinking few feet further it will penetrate the next stratum of lime, as the ore Tn the bottom is \ free milling | chloride and rich, it will be interesting to note the developments attending further work sinking this shaft. In addi- ton to the main vein the quartzite Is cut and threaded by numerous feeders or branches and the phenomenal richness of these has been source of a great DOT tion of the product of the mines. More work has been done upon the group than any other in the district and the hill is | full of holes and cuts which have been done extracting the rich ore from the different branch veins. It is however the main vein which promises so well for the future, all work upon thls show ing more or less good ore in the bottom.
 The following is an approximate of the production of the group to date:

 At the foot of the hill the Olympia, ont of the group, shows in the bottom of thu 20 foot shaft body of galena ore som' seven feet wide, the metal is distributed through quartzose gaugue and whil' the average of the whole is low it con centrates to grade of over 40 OF silve and over 60 per cent lead to the ton This group only needs capital. and tn saying so sold never had better illustra tions than are to be found in this dis trict. MT. Kron has labored incesAantl' since he first located the group, but fo one man single handed to undertake tn exploiting of silver mine is out of th question:; the extraction and shipment o ] the richer surface ores is an easy task but the necessities that arise with deel workings, make the employment of lsrg capital an absolute necessity.
