BLACK HAWK MAKES
 IMPORTANT STRIKE.

 made good progress during the past two weeks and is now in better shape than at any time since the unfortu- nate fire in the Inteiloper shaft last February. The flow of water in the mine has decreased from a maximum of 5000. .000 gallons to 3,500.000 gallons daily. This is easily handled by the pumps, although one baler is stall run at intervals, says the Globe Silver Belt.
 The water end for the new Prescott pump was received by express last week and the pump is now in place at the new station on the 10th level. There is still about g weeks work on the pump and water column before 1t will be ready to gn into commission. With the addition of this new pump the capacity of the pumping plant will be ralsed fo 6,000. GOO gallons in "A hours.
 The force of miners has been in- creased and after the new pump goes into commission full shifts will be re- stored and work resumed on all the levels of the mine.
 Good progress is being made in sink ing C. shaft, which has reached a depth of 1S0 feet. Little water has .ct been encountered.
 The important incident of the week was the blowing in of the new furnace at the smelter on Wednesday. This was accomplished without a hitch and the new furnace is running as well as the old ones. With four furnaces in blast there should soon be a consider able increase in the output of copper. Supplies have been arriving very | freely and the stock of coke on hand is very large.
 The most important strike of ore | in Globe district announced for some time was made this week on the 400 l foot level of the Black Hawk mine of the Arizona Commercial Copper com pany. The crosscnt encountered the ore body 7S feet from the shaft. al l though at 46 feet carbonate ore was uncovered in the floor of the crosscut, which Is apparently the apex of an ore body, and the crosscut Is in ledge matter carrying some copper from that point till 1t cuts the ore body, | which last Friday had been penetrated eight feet. The ore is hematite, carry ing copper and silver. of the same character as that opened on the sur face and in the upper workings, but or nlSner grade.
 The fact that this great ore body has been found to be as large and to i carry as high. if not higher, percent age of copper at 400 feet in depth as it did above, proves the Black Hawk to be one of the most valuable mines in Globe district.
 Supt. w. s. Sultan says that no as- say of the ore from the 400 foot level hoo rnf hxor, Ia hut hA SeS | fled that 1t carries more copper than the ore in the levels above, the cop per values in which average about 5 per cent.
 Sinking continues and the shaft has now reached a depth of 460 feet It will be sunk below water level, where it is expected the ore will change to sulphide.
 Pollard Pearson, who was in Globe l from the Miami property reported that crosscut had been started from the bottom of the shaft-200 feet down land that they expected to cut the ledge in 40 or 60 feet.
 | Several prospecting outfits are
 searching for gold srreaks at the base
 of the Pinal range near Globe and one
 of them who had several assays made last Friday states that he secured over
 an ounce of the yellow stuff to the
 ton Tt Is only a small streak yet
 he said. but gradually widening | Sam Gibson. who is spending most
 of the time now at the Gibson mine
 Experimenting development work, was
 in Globe. He states that they in,
 stalled a Cameron steam pump in the
 incline shaft ana are now about ready
 to resume sinking from the 300-fooi
 level. The new shaft will not be
 started before the first of July. Ort
 shipments to the Old Dominion smelt
 CT have been reduced to an average o
 about 200 tons a month, and will no
 be materially increased until the 40t
 foot level is reached.
