dike of latite-phonolite 150 feet from the shaft. At the end of this crosscut is 
another dike, said to be syenite. The main vein west of the shaft is in latite- 
phonolite. On the 515-foot level brecciated latite-phonolite appears at the station, 
but changes to massive rock of the same kind 75 feet northeast, at the first vein. 
Four hundred feet east of the shaft in the long drift and crosscut the latite-phonolite 
changes to denser phonolitic rock, 
and a dike of syenite is met at 
the Lillie line, possibly the same 
as that in the crosscut on the 
239-foot level. On the west side 
from the main shaft breccia con¬ 
tinues to the La Bella vein. 
The principal vein is the La 
Bella, which is also worked on both 
adjacent properties. Its strike is 
N. 45° W. near the surface, but it 
swings to N. 34° W. on the lowest 
level. The dip is nearly vertical in 
the upper levels, but turns 70° SW. 
in the four lower levels. Two or 
three lesser veins diverge toward the 
southeast; one of them, the Talbot, 
crops near the small Wilkinson shaft 
and is cut on several lower levels 
dipping very steeply northeast ; a 
second vein is opened at No. 3 shaft, 
400 feet east-southeast of the main 
shaft, and is also cut on the 514- 
foot level. 
The La Bella vein consists of 
several closely contiguous branches 
converging toward the northwest. 
In the vein the rock is often re¬ 
markably fresh, locally with well- 
preserved augites; in one place a 
transition to syenite was noted. 
There are usually several narrow and 
tight seams and many minor cracks, 
all coated with carbonates, quartz, 
and tellurides. 
Two shoots have been mined. One, beginning just north of the shaft and 
up to 10 feet wide on the 239-foot level, continues to the 605-foot level and thence 
pitches northward into Vindicator ground, 200 feet northwest of the shaft, where 
it has been mined on level 12, about 150 feet below the deepest Christmas level. 
A second shoot lies near the Golden Cycle line, which is only 50 feet southeast of

veins; looking northwest. (After V. G. Hills.)
