the latter mine. These southern and less important systems are opened by long 
crosscuts on levels 8, 12, and 14. Their trend is northwest or north-northwest and 
their dip very steeply southwest. They have proved productive for only a distance 
of 200 feet from the southern boundary of the Vindicator. 
The absence of cross veins is noteworthy. The two basic dikes in the northern 
part of the property carr} r no values and have no enriching influence. One of 
them, on the other hand, cuts off the ore shoot on No. 1 vein. 
The veins are generally sheeted zones of an average width of 3 to 6 feet, but 
in places swell to 20 feet. Well-defined walls are rarely seen. The country 
rock has an irregular roughly blocky structure, and the tight seams of which the 
veins usually consist seem scarcely better defined than the joints in the surround¬ 
ing latite-phonolite. On some veins a central seam with vugs is characteristic, but 
the cavities are very small. In the vicinity of the veins the latite-phonolite con¬ 
tains a little more disseminated dolomitic carbonates and pyrite than elsewhere, 
but even in the vein itself the percentage of these replacing minerals is small and 
does not greatly affect the appearance of the rock. Fluorite is sparingly present. 
As usual, the values are in the seams and, below the oxidized zone, consist of finely 
divided calaverite, often scarcely visible by the naked eye, loosely coating the thin 
quartz seams of the joints. Few other metallic minerals occur. Blende and galena 
are found in places, especially in the Sigel vein; molybdenite is likewise pretty gen¬ 
erally distributed and was specially noted from the stopes on No. 3 vein. Tetra- 
hedrite occurred in an unnamed vein on the deepest (1,200-foot) level, 200 feet 
northwest of the shaft. 
The ore, which is sometimes shipped as taken out, but more frequently screened 
and hand picked, is of high grade and for the years 1901 and 1902 averaged a little 
over $40 per ton. 
The smelting ore, which constitutes the larger part of an average daily output 
of 43 tons, contains about $58 per ton, while the milling ore, amounting to about 
two-thirds of the total ore production, averages $16 per ton. Very little silver is 
present. 
ORE SHOOTS. 
The most valuable ore body in the mine is that on No. 1 vein, which enters 
Vindicator ground from the Lillie between levels 5 and 11, and with a northwesterly 
pitch of 50° ceases somewhat below level 14. 
Another shoot continues from the Lillie No. 2 vein into Vindicator ground, 
but the richest part of it occurred on a spur from this vein called the Vindicator 
from levels 12 to 14. Excellent shoots have been found 400 to 500 feet north- 
northwest of the shaft and in the deepest levels, on No. 2 and No. 3 veins, which 
here lie on the northwest side of No. 1 vein. 
The Wallace vein or spurs close to it have carried a large stope practically from 
the surface down to level 13, the deepest from which it has yet heen opened. It 
connects with the Glorieta shoot of the Hull City mine and pitches steeply north¬ 
ward. Shoots of smaller size have been opened on the La Bella, Sigel, and New 
veins.
