 KEYSTONE TUNNEL
Two Churn Drills Working to Block Out Immense
 Ore Body

At the Inspiration Copper company $ mine a force of l50 men is engaged in underground construction and general surface work. Drifting to block out ore and explore new ground on the 400 foot level of the Joe Bush shaft is progressing at the rate of about 600 feet 8 month. Most of this work is now being done west and north of the shaft. At present the Joe Bush work ings extend from the shaft about 3T5 feet west, 300 feet north, 200 feet south and l50 feet east. The vertical extent of the ore body, as shown by the shaft work, is approximately 325 feet. The grade of the ore is nearly three per cent copper. A new. S0-horse power boiler is being installed at the Joe Bush shaft.
 The main tunnel being driven north east from the Keystone Gulch to con meet with the Joe Bush shaft 2,500 feet uIstant and thus afford a cheap means of mining the Inspiration ore body, has been driven about forty feet by force of men working with hand drills. Grading for the site of the lS5- horse power air compressor at the portal of the tunnel is practically com pleted and two l00-horse power boilers are now being installed there. This compressor will furnish power for twelve air drills to be used for driving the tunnel on the 40O-foot level of the workings of the Joe Bush shaft. 1t is expected that the compressor will be on the ground within a month. It is prob- able that as soon as ore mining Is be- gun, work will be resumed in some of the old tunnels on the west part of the Inspiration property.
 Two churn dnlls, prospecting the sup posed ore belt between the Joe Bush and Scorpion shafts are now working on the hill a. few hundred feet south of the Scorpion shaft. These drill holes are about 400 feet apart and both have encountered ore at a depth of approximately 200 feet. This depth represents the maximum thickness of the capping overlaying the ore body on the hilltOps of the Inspiration land. as shown by the churn drill work so far. On the site of the Joe Bush shaft, the capping was only ninety feet thick, the location of the shaft being far down the hillside. The drill work in the vicinity of the Scorpion shaft, supple mented by the shaft and level work done at the Scorpion so far, indicates that the ore body at that point IS sew eral hundred feet wide and from 70 to so feet thick. This ore body dips sharply to the southward and away from the shaft. At the point where the Scorpion shaft passed through 1t in sinking, this ore-body lies pretty flat. The crosscut driven south from the 275-foOt level of the Scorpion shaft encountered the ore at 120 feet from the shaft and has continued in it from that point for about l5 feet. The grade of the ore is about the same as that in the Joe Bush workings. It was near the location of the Scorpion shaft that drill hole, put down last summer, yielded samples running as high as 46 per cent copper.
 Since T. R. Drummond assumed management at the Inspiration mine, between fifteen and twenty new bunk. houses, cottages and warehouses have been added to the company s camp.
