throughout the Mizpah workings
g72 feet Of development was record
ed while the Silver Top is credited
with 1851 feet. The workings Of
the Red Plume were extended forty
four and one-half feet, making a
total for the three properties of 47S
feet. The shaft in the Red Plume
was sunk twenty feet and is now
down 572 feet below the collar.
Very little change is reported in
the workings of any of the properties
and the work is being continued in
the usual places. The $40 and $40
foot levels of the Silver Top remain
the same with no change OF note.
44O-foot level-A drift has beer
started on this level that will parable
