240 ECONOMIC GEOLOGY OF SILVERTON QUADR ANGLE, [bull. 182. 
(and probably enargite) carried from 20 to 26 ounces of silver per ton 
and 6 to 40 per cent of copper. The mine was closed in 1891. In 
L895, 2() tons of enargite ore, carrying about 20 per cent of copper, 
were collected from the dump and realized $18.77 per ton. In its 
general character the ore of this mine seems to have been very simi- 
lar to the low-grade ore of the National Belle, carrying enargite and 
copper and iron pyrite. 
Other mines and prospects, showing more or less ore occurring in 
typical Red Mountain form, occur at the heads of Prospect and Dry 
gulches on the eastern slope of Red Mountain. The Mineral King, in 
Prospect Gulch, has a shaft 150 feet deep, sunk to develop a "chim- 
ney 11 of ore which outcropped in the bed of the creek. This ore 
shoot was cylindrical in form and nearly vertical, with a diameter of 
about 6 feet. The ore was a highly argentiferous copper ore, which 
is said to have contained as much as 1,300 ounces of silver per ton. 
It was surrounded by the usual envelope of silicified andesitic breccia, 
which graded outward into less altered forms of the same rock. This 
ore body pitched slightly to the south, and was followed down for 110 
feet, when it pinched out. Forty feet deeper, drifts have been run in 
all directions in an endeavor to find a continuation of the pay shoot, 
but without avail. The rock at this level is traversed by numerous 
fissures, usually carrying some kaolin and accompanied by kaoliniza- 
tion of the wall rock. They sometimes widen into "pockets" filled 
with soft, unctuous yellow clay. One prominent fissure has a course 
of N. 80° W., another of S. 5° W., and still others run in various 
directions. It is probable that the original ore channel was formed 
by the intersection of two or more of these fissures. All of the ande- 
sitic breccia exposed in the artificial openings of this vicinity show 
some mineralization, with frequent small bunches of galena and other 
ore, but it was apparently only under exceptionally favorable con- 
ditions of Assuring that this diffuse mineralization was concentrated 
into ore bodies of workable size. 
Near the head of Prospect Gulch the Galena Queen, with a shaft 
about 300 feet deep, shows a dump of similar character to that of the 
St. Paul. It is no longer worked. 
Active prospecting was in progress in 1900 in the neighborhood of 
the Galena Queen, many of the shallow openings showing some ore. 
The Henrietta mine, in the lower part of the same gulch, is described 
with the Cement Creek mines, on page 257. 
The Webster, at the head of Dry Gulch, is worked through an 
inclined shaft 320 feet deep. The shaft is sunk on a fissure carrying 
a little gouge, in Silverton breccia. This fracture strikes about S. 10° 
W. The dip at first is about 75° to the south, but at 200 feet it flat- 
tens to about 45°. A little argentiferous copper ore has been found 
in bunches.
