approximately 260 feet. Four levels have been developed from 

 the shaft: one known as the "50-foot Level," which is approxi- 

 mately 57 feet from the collar of the shaft. Another level known 

 as the "100-foot Level," a third known as the "200-foot Level," 

 and a fourth known as "250-foot Level." 



50-foot Level. — On the 50-foot level development work has 

 been extended for a distance of 142 feet to the southwest of the 

 shaft and 172 feet to the northeast of the shaft. At a point 

 60 feet southwest of the shaft, a diabase dike was encountered ; 

 and 130 feet northwest of the shaft another diabase dike was 

 encountered. (Fig. 1, p. 168.) Most of the work on the 50-foot 

 level has been stoping of ore that existed between these two 

 dikes ; and the ore has been taken out very largely from this 

 level to the 100-foot level, also to a considerable extent from 

 this level toward the surface. (Fig. 2, p. 171.) Blocks and pillars 

 of ore have been left, some of which carry good values, but have 

 not been reckoned as a part of the ore in sight. There seem to 

 be two veins of ore, separated by a block of slate that carries 

 considerably less value than the veins ; but, as tested in certain 

 places, carry pay values. At the extreme northeast of the drift 

 of this 50-foot level the slates were tested, which show no free 

 gold; and this indicates that beyond the diabase dike on the 

 northeast there is but little ore, unless it should be found that 

 the ore-bearing portion of this slate has been faulted. To the 

 southwest of the southwest dike ore was encountered and stoped 

 for a distance of about 30 to 40 feet. The extreme southwest 

 end of the drift was tested, which showed a certain amount of 

 free gold; indication that the ore body was continuous in this 

 direction. The 50-foot level is connected with the surface by 

 an upraise of 50 feet to the southwest of the shaft, and with 

 another of 60 feet to the northeast. It is also connected with the 

 100-foot level by a winze from the stope to the southwest and a 

 stope to the northeast of the shaft. (See plan of level. Fig. 2, 

 p. 171.) 



100-foot Level. — On the 100-foot level development work has 

 been extended for a distance of 60 feet to the southwest of the 

 shaft and 102 feet to the northeast. Besides the stoping that
