CHAPTER VI— MINES BETWEEN ALTMAN AND GOLDFIELD. 
ISABELLA EODE SYSTEM. 
The first important lode system encountered when the Altman-Goldfield dis¬ 
trict is approached from the northeast is situated on the slope of Bull Cliff. The 
prevailing country rock is the usual fine-grained pyritic breccia, which, however, 
farther down on the north slope shows only a very slight degree of alteration. An 
intrusive area of latite-phonolite surrounds the veins in part. From the sections 
and descriptions given below its dike-like form, spreading near the surface to wider 
proportions, is clearly apparent. A very persistent dike of trachjnlolerite cuts across 
the lode system with a northeast strike (fig. 44). 
The two mines described below, the Isabella and the Victor, were among the 
large earlier producers, and still continue to show a small output. Their north¬ 
westerly trending system of lodes is shown on fig. 44 and, like so many others, is 
characterized by a slightly divergent direction of individual veins. A depth of 
1,200 feet has been attained in the Isabella and somewhat less in the Victor. The 
Buena Vista vein of the Isabella mine is especially persistent. 
VICTOR MINE. 
PRODUCTION AND DEVELOPMENT. 
The Victor Gold Mining Company owns the Victor and Little Joe claims, on 
the northeastern slope of Bull Cliff. The total production is given as $2,216,671 
to January 1, 1900, and the dividends paid to the same date $1,155,000. The last 
dividend was paid in December, 1898, and during the last few years the mine has 
been idle, except for a little leasing work in the upper levels. Shipping was resumed 
in July, 1904, and ore is reported to have been found on levels 5, 6, 8, 9, and 10. 
The developments comprise the Victor vertical shaft, 1,800 feet southeast of 
the Lee shaft of the Isabella. The elevation of the collar is 10,547 feet, and the 
total length of drifts, shafts, and crosscuts between 2 and 3 miles. Fourteen levels 
are turned. Level 8 is only 429 feet below the collar. The lowest level is said to 
be about 1,000 feet below the collar. 
GEOLOGICAL FEATURES. 
The prevailing country rock on the surface and in the workings is a normal 
volcanic breccia, usually of fine grain. The trachydolerite which covers Bull Cliff 
does not appear in the workings. It is reported that a flat mass of phonolite was 
encountered on the lower levels. 
VEIN SYSTEM. 
The Victor veins trend northwest and show a tendency to diverge northward. 
The dip is 70° or steeper southwest. On level 5 the main vein is traced 550 feet
