Output of Arizona Commer- cial for January Given
 at 100000 Pounds

Since the Arizona Commercial smell ter resumed running after the temper ary shutdown necessitated by leaking water jackets on the furnace, from 200 to 220 tons of ore has been treated daily, in which has been included, for the past few days, fiftY-ton daily ship ments of ore from the mine of the Su- perior X Boston Copper company. The Arizona Commercial ore making up the present smelter supply averages about per cent copper The shelter at pres ent is running smoothly, and although the repairs made on the old water jack cts will probably not prove permanent, the new jackets already ordered will, of course, not be put on until clrcum- stances make it necessary. The trouble on the water jackets is admitted by the manufacturers to be due to defective workmanship, and not to any circum- stance in connection with the running of the shelter.
 When treatment of ore was resumed by the shelter, the usual force of about $50 men was again employed by the Arizona Commercial Copper company. A great deal of ore is being broken down from the stopes along the drifts on the sixth level; smaller quantities of commercial ore are being mined on the fifth level and little ore is being taken from the fourth level, also. The drift west from the winze put down from the sixth level at point about $50 feet east of the Eureka shaft IS l25 feet long and the eight-inch vein of copper glance which was encoun- tered there last week still continues to run parallel with the main lode. From the point where the strike was made to the present breast of the drift the width of the commercial ore opened by the drlft has varied from three to five feet. Much of the ore in this drift runs as high as 10 per cent copper, while the copper glance from the rich streak, of course, assays much higher,
 The drift driven east from the winze nearest the Eureka shaft has advanced per cent. From the seventyfive foot winze put down from the sixth level drift, at a point about 100 feet west of the Black Hawk shaft, a drift has | been driven westward for about fifty feet through ground carrying conner eial quantities of copper. As yet no | drift has been driven eastward
 On the 700-foot level, the crosscut driven northeast from the Eureka shaft is forty feet long and is expected to open the Black Hawk vein with about | fifteen feet more of driving. On the seventh level the Black Hawk lode is about twenty feet distant from the Flu reka shaft in straight line, but the northeast crosseut is not being driven directly toward the vein, owing to the necessity of providing a straight run way for the ore cars from the shaft. The three pumps working on the sew enth level are keeping the water situa- ton under control Two of these pumps have capacity of 750 gallons each. The capacity of the third pump, which is of the Prescott make, is 1000 gallons per minute. The Arizona Commercial pumping plant is raising over 3,000,000 gallons of water from the mine daily. During the past few days the flow of water has lessened slightly.
 The management of the Arizona Com mercial Copper company states that the output of fine copper from the shelter for January was slightly over 100000 pounds and that the average monthly output, in the near future, is expected to be between 100000 and 500,000 pounds.
