MINING IN ARIZONA.
Cochise County.

The first shipment of structural i steel for the Calumet & Arizona Go. s new $2,0OO,00O smelter has been start ed on it's way to Arizona, and within two weeks several hundred highly skilled workers will be on the joD .. This information is furnished by Gen. eral Manager John c. Greenway The first shipment of steel is expect ed to arrive at the plant within the next few days, to be followed quickly by others. Preliminary work, Sucn as leveling, pouring concrete founda- tlonS, etc., has been proceeding rapid ly since the latter part of last year The Commonwealth is preparing to do excessive development work along lines mapped out by the directors with the expert assistance of MT. Humphreys. This will include sink ing and additional development of the ore bodies of the property already un- covered by previous work. MT. Hum- phreyS will retire shortly from his of ficial position with the company ir- tending to return to his home in San Francisco, and later to devote himself to his private mining interests, it is stated. He will be succeeded by Ed gar Collins, until recently connected with large properties in South Africa.

 Churn drill hole No. 2 of the South western Miami Development Co.,, IS 1,070 feet deep and still in the chal- cocite ore it encountered at 945 feet Hole No. is 520 feet deep in the schist formation. The two new drill in tyx-n new holes will soon be started.- Churn drill hole No. ? on the Barney group is APO feet deep. A road is being built to the location of hole No. 3 which will be drilled at the apex of the Live Oak, Southwestern Miami, the Barney properties, the expense to be shared equally by the three con- panies, as they will all benefit by the information gained. At the Inspira- tion mine, the experimental mill has been started again and J. M. Callow is conducting another set of tests. The trestle connecting the portal of the main tunnel with the site of the new steel warehouse is nearly cOni- pleted. Engineers are working on plans for the mill and development nf the ore body. At the Superior and Boston mine, development work con tinues on the 18th level. Drifting is
 
 east and west from the crosscut nort:,, and the driving of the crosscut to the southeast of the shaft continues. Al. the Gibson mine, Is miles west Of Globe, drifting is in progress on the fourth and fifth levels of the PaSquale vein and it is reported that consider able ore is exposed in the back of the stope above the fourth level.

 The Ora Plata mine has just sent to the Smelter a 30 ton car of concen- trates that are. understood to have a value approXimating close to $1O0 per ton in gold and silver. The ore from which these concentrates were male was taken from the old stopes. Lyon Kay is reported to have discovered a vein carrying copper, gold and silver in the spur of mountain between the Keystone and the George Washington mines, at Mineral Park. The outcrop of the vein shows for 300 feet in length MOyle brothers, owners of the George Washington mine, at Mineral Park which property is under bond to George Peck and others, have just shipped to the shelter two large car loads of ore that are said to have a value of over $500 in gold and silver to the ton. H. E. Bierce, of Denver, who has a bond on the McNeely prop critics at Mineral Park, has also locat- ed large acreage and it is under stood will soon begin the work of bor- ing through Ithica mountain. This is the main turquoise bearing section or the great porphyry uplift, although through it appears that veins of gold and silver bearing ore also occur i'll the belt Mining Science.
