330 GEOLOGY AND GOLD DEPOSITS OF THE CRIPPLE CREEK DISTRICT. 
When the mine was visited on January 12, 1904, the water was about 35 feet 
above level 6, or about 8,988 feet above sea. On April 17 the water was 31 feet 
lower and its recession was being hastened by pumping 360 gallons a minute. 
PEGGY MINE. 
The Pegg}^ is of interest as being one of the most recently developed mines 
in the district, work having begun early in 1903 on the Sunset, a small fractional 
claim surrounded by the properties of the Mary McKinney, Work, Rose Maud, 
and Cripple Creek Consolidated mining companies. While really in Gold Hill, 
the mine is so closely related to the Mary McKinney mine as to be best described 
in this place. The shaft, situated in the town of Anaconda, is about 361 feet deep, 
with two small levels, one 300 feet and the other 361 feet below the collar. The 
workings are all in breccia. The shaft was sunk in the expectation of finding ore 
at the intersection of a nearly north-south fissure with the Howard dike or sill. 
At a depth of 300 feet, however, a flat vein was encountered, striking about N. 
70° E. and dipping 45° N. This can scarcely be the Howard flat vein, but may 
possibly be what is known as the No. 3 flat vein in the Mary McKinney mine. 
The Peggy vein consists of a little veinlet of fluorite, usually only an inch or two 
wide, accompanied by minor parallel fissures. The ore occurs as calaverite or 
sylvanite, chiefly in the fluorite of the main veinlet, but also to some extent in the 
accompanying fractures. The best ore is said to occur near the intersection of the 
Peggy vein with the nearly north-south fissure passing through the shaft. The 
ore is said to carry from 4 to 10 ounces of gold per ton. Stoping had barely begun 
at the time of visit, and the present level 2 had not been opened. Lessees 
working through the Peggy shaft have opened a good body of ore on the south 
end of the Colorado Boss No. 3 claim, just north of the Peggy ground. This ore 
occurs as calaverite in a number of small irregular fissures of various dips, but 
striking generally N. 25° E. These fissures are in the hanging wall of the flal 
Peggy vein, which becomes very indistinct in their vicinity. 
KATINKA MINE. 
The Katinka Gold Mining Company, capitalized at $1,250,000, owns the 
Katinka, August Flower, Chicken Hawk, and Hobo claims on Guyot Hill, immedi¬ 
ately south of the Mary McKinney mine. The mine is operated by lessees. The 
underground workings comprise a crooked incline about 600 feet in depth, with 
seven short and unsystematic levels. There is also a vertical shaft, which, however, 
is not connected with most of the levels and is not used. 
The Katinka lode is a somewhat irregular southerly continuation of the Mary. 
McKinney lode. The country rock is chiefly breccia, which lies between the 
intrusive phonolite mass of the Mary McKinney mine and the granite of the south¬ 
west side of Guyot Hill. The breccia contains many granitic fragments and is 
cut by several phonolite dikes. The only important ore body of the Katinka 
occurs near the Mary McKinney line from 400 to 500 feet below the surface. It 
is the south end of an ore shoot stoped in the Mary McKinney mine above level 3. 
The production of the Katinka mine is not known, but can not have been large.
