FINDLEY AND SHURTLOFF MINES. 
PRODUCTION AND DEVELOPMENT. 
The Findley and Shurtloff mines, which are owned by the Findley Gold Mining 
Company, are situated on the southeastern slope of Bull Hill just above the town 
of Independence. On the south the property adjoins the Hull City mine, while the 
Stratton estate holdings lie on the west. The principal production has been during 
the last few years. The output of ore of the Findley mine for the two years previous 
to 1904 was 11,850 tons; during earlier years 5,000 tons were produced. The total 
production of the two mines to April, 1904, approximated $700,000. 
The developments on the Findley consist of a vertical shaft, with collar eleva¬ 
tion of 10,398 feet and depth of 1,387 feet. Fifteen levels are turned, while at station 
16 the vein has not as yet been crosscut. The numbering and elevations of levels 
are shown on fig. 50 (p. 414); the bottom level (15) having attained an elevation of 
9,119 feet. Drifts and crosscuts aggregate about 2 miles in length. The Shurtloff 
shaft is situated 800 feet north-northwest of the Findley, and its collar is 129 feet 
higher; it is 900 feet deep, with ten levels at various intervals down to the 800-foot 
point. Level 10 lies 25 feet above Findley level 9; Findley level 11 extends under¬ 
neath the Shurtloff workings without making connection with them. Drifts and 
crosscuts amount to 4,500 feet. 
GEOLOGICAL FEATURES. 
On the surface in the south end of the property the veins are contained in brec¬ 
cia, though the contact of the Altman area of latite-phonolite is only a few hun¬ 
dred feet distant to the northeast. Near the Shurtloff shaft the veins enter this 
rock and the shaft is said to have passed through over 400 feet of it before entering 
breccia, which continues down to the bottom. The Findley shaft is sunk in breccia. 
A crosscut to the northeast on level 11 reveals a sharp contact with syenite or coarse¬ 
grained latite-phonolite, 130 feet from the shaft; this probably represents the down¬ 
ward continuation of the Altman area. Moreover, though all accessible crosscuts 
from shaft to vein showed breccia, there is certainly latite-phonolite on level 11 for 
several hundred feet south of the shaft and for 600 feet north of the shaft to a point 
just north of the cross vein described below. The same rock is prevalent on level 
14 along the vein, though the crosscut is in breccia, so that it would seem as if there 
existed a dike-like mass of latite-phonolite following the vein, at least on the lower 
levels. Level 15 was not accessible, being covered with water in April, 1904. 
The breccia contains abundant fragments of latite-phonolite, and at the end of 
the east drift on the cross vein 600 feet north of the shaft much granitic material is 
present. Smaller masses of phonolite—dikes and sheets—are found in various parts 
of the mine, but have little practical importance. A small northeasterly trending 
basic dike was cut on level 14, 450 feet south of the shaft. 
A crosscut 1,100 feet long, which extends west-southwest underneath Moun¬ 
tain Beauty ground, reveals only breccia; neither the latite-phonolite nor the two 
basalt dikes seen on the surface were observed here 1,150 feet below the surface.
