 OATMAN. April 20-The crosscut in the Big Jim from the station at 4S5 feet depth encountered the downward continuation of the big vein opened at 400 feet at a distance of no feet from the shaft The cut has now penc- trated IS feet of ore, and its breast is still in ore. The ore is much more silicified and much more oxidizcd than it was on the upper level, and appears to contain larger values. Official sampling will not be done until the vein is entirely crosscut. It was en- tered from the hanging-wall side. On the 400-foot level above the vein was 46 feet in width showing an average value of S7.44 per ton in gold for the entire 46 feet. Unofficial sampling of the first six feet of ore opened on the new level is said to have given assays returns of Slo24 i1 gold.
 In the Telluride property, which lies between the Lucky Boy and the east ern end of the Tom Reed property, a vein 25 feet in width has been cross cut on the 300-foot level. This is all ore Mine sampling has just been completed, and assay returns arc not as yet available. Indications arc that it is low mill grade ore.
 The Lucky Boy shaft is now down 2S0 feet. As the discovery i1 the Telluride is on the Lucky Boy vein, the development is of considerable importance from the standpoint of Lucky Boy operators and stockhold-
 n-- e.I cf to I -l- the Telluride has orc, and on the other side the Carter has developed splendid pay orc on this same vein system. Adjoining the Lucky Boy on the south and west is the property O! the Tom Reed Junior Mining Com pany. and its shaft at 2 depth of about 260 feet is all in orc. which is said to he averaging around s or SC per ton. This vein system also goes through the Lucky Boy ground. Development in the Carter. Lucky Boy. Telluride and Tom Reed Junior in this section seems to indicate that some big ore deposits will be opened well to the southwest of the Tom Reed and Unit ed Eastern properties within com paratively short space of time.
 The Boundary Cone IS now cross cutting towards its vein on the 75O- foot level. and the downward exten- sion of the ore shoot in which has been developed a large tonnage oi ore in the 550-foot level is expected within few days.
 Adjoining the Boundary Cone, the Gold Dust Mining Company is devel- | oping a considerable tonnage of mill grade ore in the 200-foot level, in which a depth of 400 feet has been at tained at a point where operations are now being conducted. The later | al is being driven into the precipitous ! hill which marks part of this territory. |
 The .crosscut to the northwest In | the Ivanhoe property on the 500-foot level is now out about IFS feet. It Is anticipated that 1t must go to a dis | tance of about 260 feet 10 cut its vein l system.
 In the Fessenden property cross i cutting has been started to the north l and to the south from the station o1 the 500-foot level. This property Is being watched with very mucn in terest.
 The Gold Range shaft is now down about 230 feet with three shifts of men working. Layers of silicihed andcsite from two to three feet in thickness contain goli values ranging between $4 and SS per ton. The shaft is going down some distance from the main vein system on the property.
 The Adams Company, operating property located between the Nellie and the Oatman Crescent in the Black Range section of the Oatman district, has just started development work. This property mas a splendid surface showing. and shallow development work done at various places in the property has exposed mill grade ore in a number of places. The ore IS highly oxidized, and in character is typical of the big orc bodies which have been developed in other parts of the district.
 The Oatma1 Mining & Milling Company is continuing steady prog ress and there Is a general eXpecta- tion throughout the district that big body of ore will soon be opened in its Kokomo vein. The property is well equipped ,and the recommenda- tions of Engineer Edward W. Brooks are being followed in its devclopmen, campaign.
 The Espera1za Exploration Com panv is starting development of its ground in the southern section of the district. the property lying between the Lucky Boy and the Oatman Cres- . cent in part. This company has one of the most spectacular surface show ings in the district. GHi as prominent and experienced mining operators arc back of it, operations in this territory arc being watched with considerable interest. \ splendid plant oi macnin cry Is just being placed in commis- sion.
