 New Find on the 9th Level
 On the 6OO-foot level the drive south has exposed II feet of 4.16 per cent copper ore similar in character to No. 91 deposit. The latter shows pay ore in tonnage from the 9th level to approximately 40 feet above the 100-foot level, but is not being drawn upon for mill tonnage at this time Such ore extracted from it as has been milled gave return at the head of 3 percent copper. It is the plan of the management to hold No. 91 ore body in reserve until such time as the company's mill has been increased to 300 tons capacity. and to supply its present milling demand from No. 102 ore body. The latter is opened on the various levels to a depth Of 600 feet.
 The steps on the 200-foot level in No. 101 ore body shows 10 feet of pay rock with neither wall in sight At present the stope has a perpendicular length of p feet Superintendent Tulloch reports the ore to carry from to percent copper per ton. All of the ore now going to mill, save that being broken in the stope in No. 101 deposit, is mined during the ordinary course of each days work. Which means that while the mine is being prospected and opened it is supplying the company's mill with 100 tons of ore per day.
 Murphy O. Ks Property
 James s. Murphy, of Cripple Creek, Colorado. who superintended the sink ing of the shaft to its present depth of 500 feet, and the development work on the various levels prior to installa- tion of the company's fotation mill and who inspected the mine in late April. states that the result of recent development work proves the mine and assures its future. He pronounc- es the showing to be one of the most promising he has viewed during his many years experience as mine sup erintendent and mine operator
 During the month of April the com pany shipped 800 tons of concentrates to the Humboldt shelter. These con centrates had an average copper con tent of g per cent and a copper con tent range from 20 to 24 per cent.
 Big Reef Developments
 At the property of the Big Reef Copper company, located on the same mineralized belt as the Copper Lode and Arizona Binghampton estates. two shifts of miners are employed in the main shaft. As depth is gained copper indications are becom- ing more pronounced and are in gen eral of character which confirms the favorable report submitted to the di- rectOrate by MT. J. II. ShOckley, an engineer of acknowledged standing. The shaft is being equipped with 40-acre power gas hoist, 500 feet of cable, buckets, etc; 10X10 compress sor and three air-drills. The mine and gallows-frame are prac tically in place and within a few days will aid materially in the work of gaining depth in the shaft. A black smith shop equipped with complete line of tools has been erected, and the work of erecting the necessary build ings for housing the miners is well 
 The property carries a continuous outorip of copper-bearing schists for a distance of more than 2500 feet which in places shows breadth of 150 feet. The oXidized copper ores azurite, malachite. chryscolla and cu- the schists in vein lets and disseminations accompanied with considerable calcite and iron OK ide. The ore is not continuous vein on the surface, but for the distance of 2500 feet before mentioned, a series of twenty or more pits. cuts and shafts have exposed a most encourag- ing copper showing. The manage ment is therefore of the belief that commercial copper ore in large ton mage will be found at the underlying water levels This conclusion is sub stantiated by similar surface show ings on neighboring mines where de- at depth has disclosed bod ies of pay copper ore
