June Production of Calumet G Arizona Was 2,e24,00o Por.--.. of Blister copper-ccpper Queen Production Estimated at 3,4oo, 900 Pounds.

A correspondent from Bisbee wr.t- ing to the Marquette Mining Journal says:
 The work of drifting at the Pitts burg & Duluth company here is pro- ducing results; in two of the drifts the ground is very encouraging; in one CT them cnalcopyrite is showing up to IF per cent copper, and in the The other they have met soft and cav ing ground with seams of mud etc, all Of which presage ore later. It Is quite possible that the company will abandon some of its options, how ever and reduce its acreage. 1t has been reported that it's August pay ments are to be postponed and the re- organization made later. but nothing has been settled yet.
 In the Oliver shaft of the Calumet and Arizona mine. they are now no feet in the ore. most of which is in sulphides, and continuing from 710 feet in the shaft downward to the bot tom. The shaft is bottomed in the same ore, though of leaner grade than some above. This shaft is not yet within 200 feet of the depth at which the adjoining Lowell shaft of the Copper Queen found it's beginning of ore, which was at 1905, feet, and 1.005 feet in the Lowell cores ponds with 1,0S5 feet in the Oliver; so the ore that was cut at 710 feet in the later is very much higher than what was cut at 1905 in Lowell.
 Drifts in the Lake Superior & Pitts burg are again cutting ore, this time carbonates that run well in the cop per. This is in the southwestern parts of the workings.
 Drifting begins in the bottom level of Calumet & Pittsburg this week, after a year of preparation. Two pumps of combined capacity of 3.G00 gallons a minute against static head of 1.500 feet have been installed and connected up, and very heavy hoist is now under erection. The strata of rock cutting into the shaft at about the 900-foot level, and below, seem to be satuarted with water, and this has been in such volume that the company has lost more than twelve months time in its development It is now in shape to take care of an immense volume of water, with the best and most powerful pumping plant in the Southwest. Less than 200 feet ad- ditional depth viii make this an inn mense producer of copper and start it for place as one of the great mines of the world. This much is absolutely known to the management.
 June production of Calumet & Ari- zcna was 2,624.00O pounds of blister coprer. Copper Queens June pro- duction was curtailed somewhat by the changes incident to the removal to the Douglas smelter, and was about 3,400, ,000 pounds. The smeluer should make when running at regular capa- city, from $500, ,000 to 1000 GOO pounds a month.
 The new shaft of the Saginaw De velopment company, holding an option on the Worlds Fair and Muheim claims is now down 160 feet. and is going down at the rate of about if teen feet a week. This depth has been reached with remarkable speed. The shaft has been in conglomerate since seventy feet from the surface, but judging from the dip of the overlyine IlHe tbG management CApNNNS tO SC' into the lime within the next few feet But on the Junction, the property next east. the conglomerate has been found to have a very steep dip, so much so, that if it holds continuous ii may require great depth on Worlds Fair to get through it; but it probably does not maintain a continuous diI there In the old workings on this property the shaft cut a narrow lime stone belt that dipped sharply to the southeast, and it was on the contact of this seam, twenty to twenty-five feet wide, that ore was concentrated. !r the new workings they hope to reacf this same line about 300 feet down.
