The positionof the new 185-foot level is shown in the cross-section, but thereis no data at hand as to the width or grade of the ore bodj onthis level. A. J.

There has been shipped some ore said to average about6 per cent in copper and a small amount of gold. The Spa and Bonanza claims, in Sees. 3, 4, 9, and 10, T. 26 S.,R. 29 E., show copper ore reported to average from 15 to 20 percent. There are four shafts on these claims.
