MINES BETWEEN ALTMAN AND GOLDFIELD.

1,600 feet north and 500 feet south of the Lee shaft. The farthest point to which 
it has been traced is 1,550 feet northwest of the Lee shaft on level 11, but it is not 
known on the surface above this point. There is, however, in this vicinity a small 
vein dipping 30° N. on which the Comet incline, 100 feet long, has been sunk and 
a little ore obtained. The dip, as shown in fig. 46, is fairly regular, averaging 65°. 
Southeast of the Lee shaft, and on the lower levels, the Cheyenne veins join the 
Buena Vista, but farther to the southeast swings away from it, assuming a strike 
of N. 40° W. The Cheyenne is followed on many levels 1,200 to 1,400 feet south¬ 
east of the Lee shaft; in the lower levels it is steep, but flattens out above level 7. 
The three branches of the Victor vein in the southern part of Isabella ground 
strike about N. 60° W. and the westerly branch practically intersects the Cheyenne 
on level 10, but they do not persist farther than a point 600 feet southeast of Lee 
shaft. The East vein lies 100 feet northeast of the Buena Vista and is opened near 
the Lee shaft on levels 9 to 13. A third parallel vein has been cut on levels 13 
and 14, 100 feet nearer the shaft (fig. 46). 
Among the northeasterly trending cross veins the Empire No. 2 intersects the 
Buena Vista on levels 9, 10, and 11 about 500 feet north of Buena Vista incline, 
but has not been followed far on the foot-wall side. The Pharmacist intersects 
on levels 9, 10, and 11, 250 feet north of the projection of the same incline. Its 
apex should cross the Buena Vista near the incline, but is not known here. A 
smaller cross vein was noted at the incline on level 5. The Klondike vein, striking 
N. 10° E. and nearly vertical, is known only on the seven upper levels, 400 feet 
southeast of the Lee shaft. On levels 10, 11, and 12 this is replaced about the 
same distance from the shaft by the vertical Campbell vein, which strikes N. 35° E. 
With one exception no faulting is noted at intersections in the cross veins. At 
the Klondike crossing, however, south of the Lee shaft, the Buena A r ista vein has 
been faulted from 20 to 50 feet, the southeastern part being thrown to the west. 
OXIDATION. 
The original water level was unusually low in the Isabella, 900 feet below the 
collar being the figure given. As a consequence oxidation has followed the veins 
down to the bottom level, 1,100 feet below the collar, though, in the lower levels, 
much calaverite was mined with the free gold. In the massive rock on both sides of 
the Buena Vista incline tellurides were found on level 2, and in places on lower levels 
of that incline the vein is almost free from oxidation. 
ORE AND VEIN STRUCTURE. 
The oxidized ores are of normal character—a soft mixture of ferruginous clay, 
pure kaolin, and quartz, with occasional seams of manganese, all carrying rusty gold. 
Fluorite is rarely abundant, the calaverite generally being contained in quartz-lined 
seams with occasional vugs. Tetraliedrite occurred in most of the levels of the 
incline from 2 down. It has also been found on the same Buena Vista vein at the 
junction with the Cheyenne on level 11, a short distance north of the crosscut from 
the Lee shaft.
