| Last FeDruary the company began milling the ore mined during the ordinary course Of development and to date has shipped about S25,000 worth of bullion. Shipments of the latter in bars valued at $4,OO0 each, are made from time to time to the Bank of Arizona of Prescott. Work at present is confined to proving up new ore bodies that have been found in the Harqua Hala Bonanza mine. Geological conditions on the lower levels indicate that the Harqua Hala will come back as a copper mine carrying high values in gold. It will ! be remembered that the famous Unit ed Verde copper mine was a gold silver producer, solely. when pur- chased by former United States Sen ator W. A. Clark in 1888. What has . been accomplished in the United Verde mine may be repeated in the Harqua Hala mine. That such may [ be the case is well within the range of probability.
 Strike Fay Grade Ore
 When the present operators took over the property ork was immediate | ly resumed at the old fourth level 1 and a crosscut-drift driven around the caved portion of the Bonanza" stope : to the footwall for the purpose Of drawing the large tonnage of vari grade ore. By utilizing supplement-. ary milling appliances-soon to be in stalled-the greater portion of this tonnage can be reduced at a profit
 In driving across the strike of the old ore bodies to reach the footwall of the "cave" 37 feet of ore was en- countered. Fifteen feet of it as saved S17 gold per ton. The remain | ing 22 feet, while low grade, has com n'ercial value. The ore stopped from this deposit milled s9SS gold per ton. ! The same ore body has been opened on the sixth level $50. feet below). 1 by a cI5sscut S5 feet long. Two veins one pitching to the east and the other i to the west, were tapped at that point. Subsequent development demonstrate cd that the ore body Of the fourth level was formed by the juncture of !. these veins just below the floor of the level. The west vein. where un- dergoing developmnt on the sixth level gives assay returns of from S6 to S22 gold per ton. This vein proves to be ! the downward extension of the old Bonanza" vein Of which the "Castel Garden" and Bonanza" ore shoots ! were a part. Connection has been made with the deposit opened on the fourth level by a winze and an up- 1 raise in ore.
 Strike Copper suluhides
 An airhoist was set up on the sixth level and a winze sun 80 feet in
 ore to the seventh level. There. drifts were run on the vein, north. 40 feet. and south, so feet. The pitch of this ore body is 10 the south. It was in the south drift on this level that copper sulphides first made their appearance in the mine. Check assays demonstrate the ore carries about 5 per cent copper and SS5 gold per ton. As the copper-sulphide sec tion lies against the footwall of the
 vein, directly beneath the oNidized ore opened above. and pitches rather flat to the southwest, the winze was
 sunk an additional so feet and tLe eighth level established.
 On the Sth level drifts were run north and south in the oxidized ore.
 One hundred feet from the station , copper sulphides were again en
 countered in the south drift. The crosscut at that point shows an ore
 breadth of 16 feet, with the copper.
 sulphide section along the footwall
 carrying ore of the same grade as that opened above The oxidized ore on the Sth level samples S13.90 gold per ton and for a length of 90 feet
 carries gold values as high as S3S per. ton. Later the drift on the 7th level
 was continued in the exidized portion
 Of the vein and 90 feet from the station entered the same ore body that is opened on the Sth level. The [ crosscut there shows 10 feet of ore that gave SIP gold at the millheads.
 At that point winze was sunk in ore about 40 feet, an upraise was made from the Sth level to connect there
 with. and an intermediate level es- tablished. The ore in the latter has a width of r feet That this ore body will prove of considerable size is ap- parent as it has been opened a length of 45 feet and a width of 10 feet on ] the 7th level. a width of F feet at the intermediate level, and a width of 16 feet on the Sth level
 Ore Widens Out.
 The drift on the Eth level has been ! extended beyond the winze a length of 2l0 feet. giving it a total length of 300 feet. For the last 25 feet the orc has gradually widened until il extends beyond the sides of the drift crosscut will be run to determine its breadth. Recent essays gave re- turns of S2140 quicksilver per ton. | This is the latest development of i'm portance in the Harqua Hala Bonanza mine. in-as much as the drift is now | being driven under the old Castle
