WEEKLY REVIEW OF
 THE GLOBE MINES
Resume Of Conditions as Shown by Recent Issue of the Globe Silver Belt.

Although there is no authentic in- ] formation at hand concerning the fu- ture plans of the old Dominion com pany as to the resumption of opera tions in the two idle furnaces at the smelter and the No. 6 furnace. which will be ready for blowing in within thirty days. it is believed that the company intends to have it's full bat tery in operation before the beginning of summer To operate all six fur | naces. il will be necessary to have a quantity of sulphide ore shipped in from outside districts.
 While the resumption of outside shipments of sulphde ore for the old Dominion smelter is a possibility. it will not occur except as a last resort. Every possible effort is being made by the management to open up the lower levels sO that sufficient ore of the re- quired quality for smelling can be hoisted, but 1t is doubtful if the de- sired results can be accomplished by the time the management plans to blow in the furnaces which are now idle. The three furnaces which are now active are being operated wholly
 
 sulphides are concerned. as there is not quite enough sulphur in the chal- copyrite ore from the Gibson for it's own smelting and little or none in that from the Black Hawk mine of the Arizona Commercial. These are at present the only two outside mines which are shipping ore to the shelter and the old Dominion is furnishing the sulphur to flux these ores.
 There is no letup in the develop ment of the lower working of the Old Dominion, nor in the stoping in the sulphide veins. although the quarters. especially on the sixteenth level, are cramped Strenuous work is being &C., complished to open up the west end and better the ventilation and a num- Der of raises are in progress to con meet with the upper levels for this purpose The crosscut from the winze on the sixteenth level to the point where the main shaft will be sunk is progressing slowly and has yet about 500 feet to go. The sinking of the main shaft to the sixteenth will be started in about a week.
 The crosscut from the winze on the fifteenth level has penetrated the No l sulphide vein. which was twenty five feet wide as against fourteen feet on the sixteenth. but the ore is of lower grade and must all go to the concentrator The vein Is being drift ed upon in both directions and an up raise to the fourteenth has been com menced.
 The footwall drift west on the six o1, ni4 ha first crosscut. and when it is extended twenty feet further a second crosscut will be driven through the vein. The quality of the ore holds about the same.
 Maggie Vein Is Rich.
 The Maggie vein which was struck on the United Globe ground in the north crosscut on the tenth level of B shaft did not prove to be as wide as was expected. but, nevertheless. is a good working vein. although it will be some time before its contents can be hoisted The vein is about four feet wide and contains q splendid grade of pyrite. Assays have yielded as high as per cent copper and most of the ore carries sulphur to the extent of 40 per cent and over. No progress has yet been made in exploring the Buffalo vein which was struck on the twelfth level. also on United Globe ground
 Black Hawk and Great Eastern.
 The Black Hawk shaft of the Ari- zona Commercial and the Great East ern shaft of the Superior X Boston are now connected on the fifth level. the east drift on the Black Hawk vein driven by the Arizona Commercial and the west drift of the Great Eastern be- ing connected The result of the con- nectiOn will be to greatly better the air in the lower workings of both mines and will also facilitate further development work and mining by both companies.
 In the Great Eastern the vein will now ba explored to the east and a drift will be started along the footwall in that direction from the point where the first crosscut intersected the Black Hawk vein. This work is being done for the purpose of ascertaining a suit able site for the sinking of a main working shaft for the Superior X Bos- ton. As soon as the vein has been sufficiently explored. stoping will be- gin in the Great Eastern and ship ments made to the shelter
 Ore Runs High. I
 General samples taken ct various points in the 220 feet opened up in the Black Hawk vein run all the way from S9 Der cent to, 12.5 per cent. The vein 1 throughout on the fifth level in both the Black Hawk and Great Eastern l shafts is thoroughly oxidized. and en- gineers and geologists who have exam-e ined it are unanimous in the opinion | that sulphide ore will be obtained with | depth. but it will be some time before.I the re-enrichment zone can be delved l into and explored. Recent develop ments show the Black Hawk vein to be one of the richest in the district.
 The Arizona Commercial is contlnu- | ing to ship daily about thirty-five tons of ore from the Black Hawk mine The new Shaft on the Eureka claim is now about 260 feet deep and sinking is | progressing slowly.
 There have been no new develop | ments at the Globe Consolidated. al- 1 though development work continues as usual in the Gem and Globe Boston | shafts of the company. The Future Copper vein on the twelfth level of the ] Gem should be cut in week or ten days
