178 ECONOMIC GEOLOGY OF SILVERTON QUADRANGLE, [bull. 182. 
level. As is too often tke case in the mines of this region, adequate 
maps, showing the underground workings and the shapes of the ore 
bodies as developed up to date, are lacking. 
The chief product of the mine is in gold and lead, the silver aver- 
aging not much more than 11 ounces per ton. Occasional streaks of 
tetrahedrite may, however, carry as much as 400 ounces. The ore is 
carried on a Finlayson wire-rope tramway down to the mill in Eureka 
Gulch. This mill is equipped witli 1 Blake crusher, 15 stamps of 650 
to 700 pounds weight, dropping 55 to 60 times a minute, 3 Bartlett 
tables, 2 Wilfieys, and 2 canvas tables. The power is water. The 
batteries are provided with one amalgamated copper plate each. The 
capacity of the mill is 30 to 35 tons daily. In 1900 this mill was not 
in use, and all the ore was sent down on a Finlayson tramway to the 
new mill at Eureka, originally designed for a concentrating mill and 
furnished with rolls. The equipment of this mill is at present one 11 
by 15 Blake crusher, 20 stamps, 3 Wilfiey tables, and 5 Bartlett tables. 
Power is supplied by 2 Pelton water wheels. 
La Belle Creole. — This claim is on the main Sunnyside lode, which 
has here turned so as to strike east and west, dipping south 75°. The 
croppings are very prominent and have been worked by open cuts 
and through a small tunnel. Several pockets of good ore have been 
taken out near the surface. 
The Lake claim is on a prominent lode just north of Lake Emma. 
This has also produced some good ore and has been worked hj an 
open cut and small shaft. The strike of the fissure is N. 74° W., and 
the dip practically vertical. The continuation of this lode toward 
the east is lost beneath the talus. On the west it appears to be con- 
nected with the George Washington lode, although the two are not in 
line. 
The George Washington is a strong lode, striking east and west 
and dipping south 70°. It also has been superficially worked by an 
open cut and a shallow shaft. In 1900 a new prospecting shaft had 
been sunk south of the vein and a crosscut driven across the latter, 
here over 100 feet wide. About 20 feet of veiy compact rhodonite 
was cut through about in the middle of the vein, and alongside the 
rhodonite, on the north, is about 5 feet of ore, carrying in places as 
much as 9 ounces of gold. Most of the vein, however, is of low grade. 
The relation of the rhodonite to the ore is similar to that described in 
the Sannyside mine. The George Washington vein shows no gouge 
and no regular walls. The ore resembles thai of the Sunnyside in 
general mineralogical character, but perhaps carries more galena. 
The lode apparently curves and passes through the saddle into Ross 
Basin, down which it is easily followed by its remarkably prominent 
croppings. 
Ben Franklin mine. — This is an enormous lode of low-grade ore, 
in places over 100 feet in width, which crosses Eureka Gulch about
