MINES BETWEEN ALTMAN AND GOLDFIELD.

a northeast-southwest vertical fissure came in and increased the value and size of 
the ore body. 
A second ore shoot on the Zenobia vein occurs on level 2 from the main shaft, 
where a stope has been made from a point west of the shaft 60 feet to the Zenobia 
line, both above and below the level. Both rusty gold and tellurides were found 
here, and some pockets were very rich. 
A body of ore of good grade was encountered about 80 feet southeast of the 
vertical shaft on level 1. A poorly defined vein of the northeast-southwest system 
is here cut by a north-south series of vertical fractures. The rock is unoxidized, 
and silicified along the openings. Carbonates are common in the seams and are 
as ociated with tellurides. A chamber 20 by 20 feet, 30 feet high, was stoped at 
this intersection, and the screenings were shipped. 
ZENOBIA MINE. 
The Zenobia mine belongs to Stratton’s estate and occupies the northeasterly 
projection of the large area on Bull Hill, owned by this company. It was one of 
the earliest producers of the camp; its output is stated to have been $140,863. 
A few years ago W. S. Stratton reopened the mine, sinking a vertical shaft 500 
feet deep. The explorations were not very successful, and in 1904 the mine was 
worked only on a small scale by lessee. 
The developments comprise an incline, now abandoned, with seven levels, 
and located 225 feet southwest of the Pharmacist incline; also a new veritcal 
shaft 527 feet deep, with four levels, 215, 315, 415, and 515 feet below the collar, 
which has an approximate elevation of 10,675 feet. Level 4 is about 100 feet below 
level 7 of the old incline. The total length of drifts and crosscuts is 4,000 feet. 
The few exposures visible on the surface indicate breccia, but in the upper 
levels latite-phonolite is the dominant rock. In levels 1 and 2 of the vertical 
shaft only latite-phonolite is exposed, while level 4 shows much breccia, chiefly 
consi ting of fragments of latite-phonolite. Abundant granitic material is also 
contained in the rock in the northwest crosscut. 
The veins worked are the Pharmacist, opened chiefly on the northeast side 
of the incline close to the Pharmacist claim, and the Zenobia, which is developed 
chiefly on the southwestern side of the incline. The Pharmacist vein here strikes 
N. 50° to 65° E. and dips 60 NW., while the Zenobia strikes from N. 20° E. to 
almost north-south, the dip varying from 60° to 80°. These two veins intersect 
along a line with northerly dip and are exposed down to level 5 of the incline. A 
fault takes place at the intersection, the eastern part of the Pharmacist vein being 
thrown from 10 to 20 feet to the south. West of the intersection the Pharmacist 
vein is not well defined. Development on the 515-foot level has disclosed three 
veins within 175 feet, which strike approximately like the Zenobia and which may 
be branches of that vein. 
Both veins show unusually large amounts of smoky quartz, much of it well 
crystallized, occurring in fissures and in cavities formed by solution. Little fluorite 
is present, and the ore is oxidized to the deepest level. Large amounts of yellow 
opaline silica are present as the latest vein mineral, and at many points cover druses
