PART II.-DETAILED DESCRIPTIONS OF MINES. 
CHAPTER I.—MINES NORTH AND EAST OF THE TOWN OF 
CRIPPLE CREEK. 
MINERAL IIILL. 
The southern slope of Mineral Hill contains a great number of prospects, on 
some of which much work has been done, though all operations were suspended in 
1903. These prospects are almost wholly confined to the area covered by breccia. 
The rock shows strong evidence of mineralization in places, being bleached and 
impregnated by carbonates and pyrite. The Roanoke shaft is located pn the 
reservoir ridge immediately north of the town, and sunk to a depth of 375 feet, 
water now standing 308 feet below the collar. It is reported that a well-defined 
north-south vein was encountered, containing some ore. A little higher up are 
the Sunflower shafts, each 100 feet deep, with about 800 feet of drifts.® Still 
farther north and about 200 feet vertically below the summit are the Laura Lee 
and Addie C. shafts, the former 100 feet, the latter considerably deeper—458 feet, 
according to report. Some quartz containing native gold is said to have been 
found in the Laura Lee. 
CARBONATE HILL. 
Carbonate Hill rises a short distance east of Mineral Hill. Its summit is made 
up of granite, while volcanic breccia covers its southwestern slopes. Like Mineral 
Hill, its slopes are dotted with prospect holes, but thus far little of permanent value 
has resulted. Near the summit is a phonolite dike, in and near which some oxi¬ 
dized ore has been found. On the southwestern slope the Elkhorn mine is located, 
in breccia. High-grade ore has been shipped from this property at intervals. The 
shaft is 450 feet deep. Toward the east the breccia extends across the gulch and 
covers the western and southern parts of Tenderfoot Hill, but the productive area 
is not encountered until the slopes of Poverty Gulch are reached. 
POVERTY GULCH. 
Poverty Gulch, heading at Hoosier Pass, separates Tenderfoot and Globe hills 
and extends down into the town of Cripple Creek. Its upper course lies over 
breccia containing some dikes of phonolite, latite-phonolite, and basalt, but a short 
distance below the C. O. D. mine it enters the schist and gneiss areas. Dikes and 
principal veins trend north-northeast or northwest, the former system being the 
most productive. The Gold King basic dike is of remarkable length and evidently
