The churn drill work which has been
 conducted on the property of the In
 spiration Copper company for the past year, taken in conjunction with the un' derground drifting, indicates in a gen eral way that the low grade ore body is approximately 5000 feet long and | varies in width, a north and south eX- | tent of the ore for 500 feet having been shown by the drill work in the vicinity of the Scorpion shaft, which is located 1 2400 feet northwest of the Joe Bush shaft where sulphide ore in quantity was first encountered on the Inspiration mineral land.
 While the churn drill results are not | taken by the management as data of sufficiently definite and detailed char acter to make any estimate of tonnage based upon them advisable, yet they | do indicate in fairly accurate way | the probable extent of the ore and also the approximate percentage of cop per which it contains The ore as shown extends between the Scorpion and Joe Bush to the Miami line toward which drift on the 400-foot level is now be- ing driven to develop the ore body in that direction and thus check the re- I.sults of the churn drill operations. | The exploratory work of the drifts and the churn drills have not yet indicated any western boundary to the ore and thus it may develop that the great area which the company owns to the west of the proven ore body may also prove productive of chalcOcite ore. The | three churn drills now in operation on | the Inspiration land are constantly set ting the boundary of the proven ore | further west toward the old Taylor tun- Hel, fact which is extremely encour- l aging for the future of the Inspiration Copper company. At present the drills are sinking holes Nos. 504, 606 and sos on top of the hill south of the Scorpion shaft. Holes Nos. 504 and sos are in
 ore and No 606, having just been started. is still in the capping.
 Much of the development work at | present is being done on the tunnel | level. or in other words, at that depth at which the extraction tunnel will in | tersect with the Joe Bush shaft. This portal or intersection IS lZi leeJ dpoNC the fourth level. With the aid of the machine drills put in commission at the | mine about the first of April the driving of the Tunnel from Keystone gulch, which vii have total length of about 2200 feet, is progressing at the rate of eleven feet daily. The drift driven southeast from the Scorpion shaft on | the 275-foot level to intersect with the extraction tunnel near the Joe Bush shaft is 400 feet long and the face is continuing in sulphide concentrating ore. On the 400-foot level of the Joe Bush shaft the blocking out of the ore is being continued by drifts and raises. One drift is being driven westward and has attained length of about 45O feet. A drift driven east toward the Miami line is 300 feet long.
 The old mill which was built on the western part of the Inspiration prop erty by the former owners is being torn down and much of the material from it will be used erecting a test mil in the vicinity of the Joe Bush shaft.
 The Inspiration Copper company is employing 200 men in development work.
