OLD DOMINION OPERATIONS
General Resumption of Business in
 Globe.

In its weekly review of the mining industry in Globe and vicinity the Sil- yer Belt says:
 The Old Dominion Copper Mining & Smelting company is gradually increas- its force of employees by the addition of a few men every day. Operations at the mine and smelter are very sat- isfactory. The briquetting machine. to treat the fiue dust, has been repaired and is running successfully. An ap- paratus has been constructed for cool ing the water from the furnace jackets which admits of the water being used over and over again, thus effecting n great saving in the quantity used. and which will be of great utility when two furnaces are running.
 Randolph Van Liew, late with the Anaconda Copper company, arrived from Montana on Monday and has en- tered upon his duties as shelter super intendent. He is a very capable mau in that position.
 John N. Judson, engineer with the American Metal company of New York is inspecting the property. The Ameri- can Metal company are agents for the sale of the Old Dominion company's product.
 F. L. Tombs, who has been in town this week from Summit district, says the principal work being done there at present is on the Little Jim claim own ed by Tom Reynolds. the Little Man. owned by Pasquale Nigro and F. l.. Toombs, and on the claim owned by the Gibsons. On the Little Jim there is about 200 fleet of work, not including a tunnel being run on the vein. three or four feet wide. The ore at this depth is low grade. The development on the Little Man measures about 700 feet, in cluding a stope 50 feet long of chalco- pyrite ore, nearly one foot wide and averaging 30 per cent. copper. There is also an ore shoot showing in the drift and the end of the drift is still in good ore. About 70 tons of this ore has been taken out.
 The Gibsons have opened their claim by shaft, sunk 200 feet, and a level run at 100 feet in depth. A level at 200 feet has been turned. The showing at the bottom of the shaft is good there being about four feet of ten per cent ore. At the first level drifts have been run each way for a distance of 100 feet. Ch llllS leNti lfle OlDSOIlS nave SIODeQ about 150 tons of ore averaging between 9 and 30 per cent. They will have d carload of ore ready for shipment with in few days.
 The vein in all of these claims is a Assure, the course of which is inde- pendent of the strike and pitch of the formation. Development thus far has shown three ore zones. The surface workings revealed rich, reformed ores going as high as SS pr cent copper Gen orally barren zone is found underly- ing the reformed ores; and below that near water level rich sulphides are en- countered-this being known as the zone of the second enrichment, caused by an upward and downward move ment of the mineral solutions; the av- craze of the ore here is from 20 to 30 per cent. After passing through an- other barren zone 30 to 90 feet, the prI- mary zone is found, at which depth no change has been made subsequent to the original depositions of mineral. This later ore zone is now being opened up. On the Columbia Copper com pany's mine the shaft is in this zone at 300 feet. in ore extending on both sides of the shaft. and averaging about ten per cent copper. The Gibson shaft al
