The Boundary Cone h.
 creasing it's Rich Reserves.

The recent strike on the Boundary Cone, on the 450 level west, is still inn proving in width and value. Assays from the ore as it comes from the pay streak gave results of 1878 gold to the ton, while the whole mass of vein nat ter. aside from the pay will give high milling values. This ore has been entered for distance of sixteen feet, and the pay ore has increased from a few inches to sixteen, and is still in- creasing in width as the drift is beng driven ahead. On the level above the vein matter gave only trace, which is an incouraging condition, indicating the increase of values with depth. On the east level splendid ore was dis covered, a shoot being encountered from winch the virgin gold was talk en. It was on this shoot that an at tempt was made to sink wlnze, but the volume of water encountered made it impossible to go below fifteen feet. Mir. Vassar the superintendent of the property, who was in Kingman yester- day. exhibited to us small box of the ore that came from this level, the greater part of which was pure gold, some of the nuggets being as large as hen egg, while the gangue in other pieces being literally laced and seam- ed with the yellow metal.
 Since the company was organized few years ago shaft has been sunk on the property to depth of 475 feet, 1918 feet of drifting, l26 feet of cross cutting, and thirty feet of winze has been credited to development. This work has all been done with possibly the smallest amount of expenditure of any like work in the county. The shaft has been equipped with a small gasoline holster, capable of going to depth of 600 feet. It is the intention to sink the shaft 100 feet deeper with this equipment and then replace it with electric machinery capable of going to depth of more than 1000 feet.
 The mines of the Boundary Cone Gold Mines company, are situated west of the Tom Reed and in the same gold belt. Since the first strike below the older andesite, on the 25O level east the mine has attracted considerable attention, as having exploded the theory that the ore did not go below the contact. Since that tiue the mine has been striking some of the most phenominal ore ever taken from a mine in Arizona. and it is probable that the ore now showing in the west drift will give up some of the very richest of that rich vein.
 The directors of the company are men capable of financing the property. the president being Fred E. Bies, of the Eagle Rock bank, Thomas c. Job, at one time well known attorney of Prescott, being vice president: I. D. l.. Williams. wealthy cattleman of the Prescott country, now residing in Los Angeles, secretary; Calvin Hartwell coroner of Los Angeles county, Charles Grimes. president of the Tom Reed Gold Mines, w. F. Ball. wholesale tobaccost, and Dr. s. M. Barnes, being the directors. J. M. Vassar, who from the results obtained certainly knows his business, is uperintendent of the property, having acted in that capa- city since the first work was initiated
 o. E. Daue, the Denver mining engineer who has been sampling the Gro Plata mine, was delayed with the work this week by the breaking down of the boiler, necessitating the secur. ing of boiler makers from Needles to repair the damaged boiler. The work will be completed in a few days and it is understood that MT. Daue will re- turn and complete the examination. He was well pleased with the prop erty so far as the examination could be made. Mir. Stanton, who accom- panied him to the mines last Sunday reports that while Mr. Daue is well qualified as mining engineer he has also established a reputation as kill CT of rattlesnakes, having killed five of the reptiles on the trip of sixteen
