BATTLE MOUNTAIN MINES, WEST GROUP, AND OUTLYING PROSPECTS. 475 
major and minor veinlets, which carry sylvanite or calaverite, associated with 
pyrite and a little sphalerite. The tellurides are not always visible. They occur 
most abundantly in the two main fissures. M«re or less p} 7 rite occurs disseminated 
through the rock of the lode and as small stringers and bunches. It is said to contain 
no gold. This ore bod} 7 was of comparatively recent discovery at the time of visit, 
and had been stoped for a length of only 25 or 30 feet. 
The west lode on levels 6 and 7 is a barren sheeted zone in granite. On level 
8, however, a good body of ore has been stoped from this lode for a length of about 
150 feet. The best ore occurred in the northern part of the pay shoot, where some 
phonolite occurs in the line of Assuring. At the north end of the shoot several 
minor fissures intersect the main lode and are accompanied by a local widening of 
the ore. Similar ore bunches occur on levels 9 and 10, where the West and Cross 
lodes intersect. 
The Cross vein contained a body of ore lying chiefly on the southeast side of 
the junction of this lode with the granite lode and extending from level 6 to a point 
about 40 feet above level 5. The maximum length of this pay shoot was about 
150 feet. A small body of ore has also been stoped on level 10 from the Cross lode 
for a short distance on each side of its intersection with the West lode. 
UNDERGROUND WATER. 
While the original water level in the Granite was probably, as in the Portland, 
at about 9,452 feet above sea, or 688 feet below the collar of the shaft, the mine has 
been drained by the deeper workings in the vicinity and is now dry. 
MONUMENT MINE. 
INTRODUCTION. 
The Monument mine, owned by the Monument Gold Mining Company, of Colo¬ 
rado Springs, capital, $300,000, adjoins the Dillon on the north. It, too, is a small 
mine, the underground workings being confined to the narrow and very irregular 
area in the Monument claim that is not covered by older locations. It is almost 
completely inclosed by the Granite claim on the west, the Portland property on the 
north and east, and the Dillon claim on the south. The company was incorpo¬ 
rated in 1898 and has operated the mine under the leasing system. 
UNDERGROUND DEVELOPMENT. 
Access to the mine is through a vertical shaft about 550 feet in depth. There 
are six levels at various distances apart. 
LODE SYSTEMS. 
As in the Dillon, there are a number of narrow sheeted zones of no great width 
or persistency. The Monument lode lies west of the shaft and runs nearly due 
north and south. It dips about 80° E. About 150 feet north of the shaft it is 
joined on the east side by the Kurtz vein, which strikes northwest and dips about
