0be MINES of ARIZONA

new road leading to the companys camp from the main trail to Jerome has been completed with the exception of few culverts, and the work of erecting the camp buildings is well ad- vanced. As soon as the mine ma chinery is in operation the crew of miners will be augmented with a view ] to opening ore bodies at depth in the 1 shortest time that is compatible with safe and sane mining. In the interim, work will be continued in the various L tunnels for the purpose of making de- terminations which will serve as | guide to operations in the underlying stratas of copper ore"
 loma Prieta Looks Good
 Recent developments in the Loma Prieta workings are very encouraging and lend emphasis to the contention of | 1 local inning men that large and val uable body of copper sulphides under lies the Copper Basin section. The | shaft on the property has a depth Of | l l55 feet and is in ore, heavily impreg- | mated with chalcopyrite, from the six 1 ty-flve foot point to its bottom. In | other words, the shaft is in ore for a | depth of ninety feet. \ considerable | tonnage. mined in sinking his com- mercial value, and there are several tons of sorted ore on the dump that | A few days ago level was established at the 140foot point and crosscuts started east and west in the ore. The face of the east crosscut is completely filled with chalcopyrite. This condi- tion has prevailed from the shaft to the present point of development and shows indications of continuing sev- eral hundred feet further to the east

 bit of attention in mining circles is the
 McNulty & Mcbride, where a churn- urIn plant recently began operations TWO shifts of nine men each are at work, and three holes are being drilled , As yet no determinations have been made public The holdings show very
 favorable copper indications at sur r lace and nominal depth, however, and ? the opinion is general that the churn- drills will disclose commercial values at a depth. The venture is backed by 3 the Crawford syndicate
 < High Gold Values
 | F. A JOnnSOn, the recently appointed
 superintendent of the Gold Blossom s Mining company, whose holdings are 1 located about six miles south of Pres- f cott, has three shifts of miners on the e job and will sink the main shaft to a 3 depth of 300 feet. The present depth V of the shaft is 200 feet On that level . an ore-body three feet wide is being . developed. Gold values are reported to i; run close to s100 per ton. This ore- n body is again to be opened by crosscuts S and drifts run out at the 400 and 50O- r loot levels. hoisting plant, air com = pressor and other mine equipment is S in transit to the property
 n Officials of the Big Ledge Develop = ment company announce the purchase y Of the old Treadwell shelter at Mayer e and that 1t is at once to be overhauled
 and placed in commission. They like t wise announce the purchase of the r Blackberry and Gopher groups and the e intention to thoroughly develop them d The company has for some time oper- le ated the Henrietta and Butternut
 mines in the Big Bug country. The
 announced intention is to reduce the
 ores mined on all four of the properties
 mentioned at the smelter recently
 bought.
 Stringers of ore showing native cop
 per have been encountered in the
 limestone -capping at depth of 400
 feet in the Dundee Arizona shaft. The
 property is located in the Jerome field and is viewed with favor by the min- = ing men there Considerable water is
 seeping into the shaft, but is not ham,
 pering operations as the plant of ma
 chinery recently installed is amply
 capable of handling both water and | waste.
 Midnight Test Sold
 The Midnight Test group of gold
 bearing claims have been sold to R. M
 Merrill of San Francisco. The property
 is one of a number of former producer.
