| shaft cn the north side which reaches seventy-six feet on a steep incline. At the bottom of this shaft there are cross cuts run towards the hanging and fcot walls and ore is penetrated i eighteen feet on one side and thirteen i feet on the other, but this dOes nOI represent the actual width of the vein as ore appears in the face of these crosscuts. From the Senator Morgan workings the Saginaw people shieped l 800 tons of ore, and the values in cop per derived ran as high as p per cent. ! There is considerable ore On the dump | here which will furnish smelter for 9 long time.
 In the Morgan group there are ihe 1 Senator Morgan, Gladstone, Margaret. i Nellie, Cardinal Gibbons, Kathryn and Imperial. The greatest development is On the Senator Morgan property but there is some work On the ether claims also. The Imperial has : well defined ledge and the cTes here carry gold as well as copper This mine has an old shaft which was sunk in, the early days by Mexicans and there are two ''vassars" there where the ores were smelted. The Cardinal Gibbons has also received some attention.
 
 Mir. Martin will begin active devel- opment of these properties in a few weeks. and the ore will be accumu- lated for smelter. It is the intention of Mir Martin to thoroughly develop his mines before he places a smeltar Cn them, but to. the casual visitor there seems sufficient justification at the present time for the expenditure of a large sum to begin smelling opera 
 secured or the attainment of depth no enc can question. The character of the matriX points to the presence Of sulphide Cres below and more perma- nent veins. The surface ores are car bonated and OxidiZed, and with, the vein of decOmposed lime running wiJh the carbonate ere il is but natural to suppose that the copper values were leached and are contained in suli3d1ide below. This decomposition eliminated the sulphur, the iron which remained in the veins was converted into oxides, the copper went into solution and was carried to the depths below Owing to the presence Of irCn, lime and silica the ores of this camp will probably be wholly self-fuXing, and if this is not true Cf one group the comingling of the ores will supply the required ma terial for fiuXing, sc that coke alone will be the only imported commodity | in the treatment of these ores
 
 The Martinez camp is located in the | foothills of the Sierrita mountains, and | the formation which contains the cop | per deposits is an altered limestone. MT. Martin secured these mines at an | outlay of S100,000, and he will expend | considerably mere than this sum in | the development of his mines and the | building of a camp here. i smelter site is owned by Mr Martin four miles ! from the camp near the Santa Cruz river. Tie water supply at present | comes from 2 well located near the Morgan group.
 In the development cf these mines there is sen the beginning Of 2 great copper camp, and one which will add 10 the prestige of Tucson as a mining center. MT Martin is at present in the east, where he has organized q strong company tc' operate these prop critics Cn an extensive scale. l know of no place in the southwest where one can find 9 richer field. nor camp which promises greater returns than The Azurite mine, which was reported to have been sold this week fer $50G,000, will be visited to- morrow. and readers Of The Republi- can will be given a description of this new copper producer which has sud- denly attracted the attention of min ing men throughout the country
