238 BCONOMIC GEOLOGY OF SILVEKTON QUADRANGLE. [bull.IsI 
In L800 the Silver Bell, with other mines, came into the possession 
of the American Belle Mines, Limited, of London, and in L89] thl 
mine was worked through a vertical shaft 706 Peel in depth, with fcei 
levels. At litis depth aboul <'><"> gallons per minute of strongly cor- 
rosive water had t<> be removed by the pumps. According to Supeii 
intendentl [arvey, this water was "st rongly impregnated with sulphura 
acid generated from the pyrites in the ore bodies." 
The rich ore found in the upper Levels changed in depth i<> large 
bodies of low-grade ore consisting chiefly of pyrite and carrying less 
than 20 ounces of silver. Most of the high-grade ore seems to have 
been extracted when the mine Came into the possession of its new 
owners, and after some attempl to work the low-grade ores in the face 
o\' t he falling price of silver the mine was abandoned in 1804. Details 
o\' the character of the ore and its changes are lacking, but the ore 
bodies seem to have been generally similar, in shape and ill their 
relation to the country rock, to those of the Yankee Girl, 
Congress mine. This ore body, situated about a mile south of Ked 
Mountain, was located in the autumn of 1881, and sold the following 
year for $21,000. In L883, according to the Mini reports, the mine 
produced about 2,500 tons of ore, valued at $220,000. It was worked 
through an adit tunnel and a shaft 350 feet in depth sunk from the 
tunnel. In L899, after some years of inactivity, the mine was beinl 
reopened. The shaft was carried to the surface and new buildings 
and hoisting plant were in course i)[' erection. 
'The old workings were not accessible in L800, but the ore bodies 
appeared to constitute a chimney-like stoek deposit of the kind char- 
acteristic of the Ked Mountain mines. The ore occurs in irregulai 
bunches, although there is said t<> be some indical ion of a vein run nine 
nearly north and south. The richest Ore was found in a soft, decom- 
posed streak near the surface and carried from $12 to $20 in gold. 
The ore is chiefly enargite, but there are also bunches o( galena 
which are said to occur on the peripheries i^' the ore bodies. Til 
enargite as seen near the surface had been partly brecciated am 
recemented by a very compact, soft aggregate apparently largeh 
composed o[' kaolin. In 1900 the mine was again idle. 
St. Paul mine. — This property, lying a short distance south of ih • 
Congress, shows certain points of resemblance to the latter. Somu 
ovv was formerly extracted from a shaft 75 feet deep. The prcseu 
workings comprise a vertical shaft 200 feet deep, with some drift 
at the 200-foot level. The ovr is low grade and consists chielly ( 
enargite with some galena, forming a line-grained aggregate. 
occurs in Irregular bunches in much altered andesitic breccia o( tl - 
Silverton series, which, near the on\ is heavily impregnated with lii E 
iron pyrite, associated with small knots and veinlets o( kaolin. >' c 
definite line can be drawn between ore and country rock, the form' 
being largely a replacement o( the latter. The ore bodies are foui
