from the winze that was being sunk from the 200-foot to the 

 250-foot level, which gave $19.75 on assaying, gave tailings as- 

 saying 90 cents. The ore from the 200-foot level, as it was 

 delivered to the mill, asayed $53.20. Tailings from this ore 

 assayed $4,35 on the first run. On the second run, where the 

 ore assayed $54.02, the value of the tailings had been cut down 

 to $2.88. The concentrates from the first run gave values of 

 $133.03, and on the second run, $81.57. This, of course, is 

 accounted for by the fact that the concentrates were not as 

 clean as in the first run. The concentrates were carefully tested 

 by panning, but showed no free gold. This was also true of the 

 tailings, which indicates that there is a very complete amalga- 

 mation of free gold on the plates. The fineness of the Coggins 

 gold, as determined in the Laboratory, was 904.
