STRIKE EXPECTED IN THE UNITED
 WESTERN
(From Los Angeles Mining Bureau)

Principal interest in the camp at this time centers in developments in the United Western property which, in the opinion of mining men, is on the verge of a discovery of commercial ore. In the crosscut to the south west on the sos foot level at a dis tance of 200 feet from the shaft, stringers of ore are being encoun- tered and a very radical change of formation is accompanied by a flow of water. The stri1eers contain quartz veins running from 6 to To inches in width, the quartz highly stained with huorine. The first strin- ger encountered showed an average of value of Sl6.6S for width of , inches. The crosscut Is now into al ternate stringers of highly mineral ized a1desite for a distance of about feet, with the entire formation showing heavy pan values. Mining men who are familiar with develop ments on the Big Jim and United Eastern state that the character of the zone now being cut by the Unit ed Western is identical with the zone lying just outside of the main ore bodies in these other properties. The inflow of water is also regarded as 2 very favorable sign, as in the devel oped mines in the district the veins which hold important ore deposits usually carry some water.
 The shaft of the Boundary Cone is now down 700 feet, and the con tact zone between the younger and older andesite has been passed. The bottom of the shaft is now in tle green chloritic andesite in which the largest ore bodies in the district have been found up to this time. The Boundary Cone is making about 4 fee: per day in sinking operations. The shaft will be sent down 750 feet, and possibly 800 feet, before lateral work is resumed. On the sos foot level in this property quite large amount oi commercial ore has been opened.
 The Gold Dust Company has taken over about 40 acres of tte old O'Ryan property adjoining the Boundary Cone, and has started extensive de- velopment. There are three shafts on this property ranging from 300 to 800 feet in depth. witt more than 5000 feet of lateral workings. Some years ago the operators of this prop erty constructed a mill, but it was not able to recover the values he'll in the ore, and the company was forced out of existence. The Gold Dust Company takes over the old main workings of the O'Ryan and all of the equipment excepting the mill. There is quite a tonnage of commercial orc still exposed in some of the old workings. The new oper- ators intend to go to greater depth, and at the same time to do develop ment work at and above the 800 foot level in order to solve the fault zone which was encountered by the for mer operators, and which they made practically no attempt to solve.
 Splendid progress is being made in sinking the shaft of the Oatman Gold Mining and Milling Company from the 315 to the 800 foot point. The bore is now down 475 feet, and has cut number of strirgcrs and spurs showing intense naturalization with very flattering values in gold. When the 800 foot point is reached exten- sive exploratory work will be done at that level, and it is the belief of Engineer Edward w. Brooks that i'm portant ore bodies should be found on this level
 The Oatman United Company IS building road to its property and is making preparations to conduct a very extensive development cam paign. A splendid machinery plant is being ordered, and this will be sui ficient to work to depth of 1000 feet. President Charles s. Sprague of this company states that the ma chinery men wno are supplying the equipment are taking great interest ill this plant, and that every efforl will be made to set a new record, not only in the installation of the plant. but in driving the big working shaft down to the 800 or 600 foot point. This property lies alongside the great Tom Reed. United Eastern and Big Jim mines, and number oi engineers believe that within this ground lies the key to some of the geological and petrolos;cal agencies which have worked for the dcpOsi- ton of ore in the central part of the
