MINES AT HEAD OF SQUAW GULCH. 
The vertical shaft begins in breccia about 250 feet south of the granite contact. 
Nothing but breccia is disclosed in the mine workings, and the granite-breccia con¬ 
tact must therefore be steep. The breccia is in general rather fine grained and 
contains much pyrite. 
Three veins are encountered in the mine. On the Discovery, or Hoosier, vein 
the incline shaft was sunk. The vein has a northwesterly strike and dips 65° to 
80° NE. The second vein, called the Ore vein, strikes about 15° more to the north, 
and is nearly vertical. The third is a flat vein, dipping slightly to the south, and 
crosses both the others at a depth of about 250 feet. 
Good ore occurred along the Ore vein, but near the intersection with the 
Hoosier vein the grade was lower; rich ore was, however, found below this inter¬ 
section. The Ore vein is a sheeted zone in breccia, much oxidized toward the top, 
and carries streaks of quartz and kaolin. The upper part of the vein contained 
oxidized ore with free gold. The values are said to have been largely in the kaolin. 
Below the 200-foot level oxidation was slight and fluorite with tellurides made 
their appearance. A 1-inch seam of manganese oxide, probably psilomelane, is 
seen in the vein on level 5 of the vertical shaft. The values of the ore mined 
averaged about S60. 
A shoot pitching to the southeast and averaging 70 feet in horizontal length 
extended from near the surface down to about 350 feet on the Ore vein. Two 
hundred and fifty feet below the surface, at the intersection with the flat vein, the 
width of the pay shoot was reduced from 14 feet above it to 6 inches below it, and 
though the vein was stoped for another hundred feet down, the values were not 
good. It is estimated that 6,000 tons of ore were taken from this stope. A small 
pocket of ore was mined on level 6, 100 feet southeast of the vertical shaft. 
A short distance northwest of the Hoosier is the Friday shaft, sunk 150 feet 
deep between the two veins mentioned above. From a lower shaft on the Friday, 
200 feet deep, some ore is said to have been extracted along a dike. 
HEAD OF SQUAW GULCH. 
Squaw Gulch heads in an amphitheater surrounded by Raven, Bull. Ironclad, 
Globe, and Gold hills. There is here a large area of breccia which has thus far 
proved notably unproductive, though surrounded by mines of demonstrated value. 
No work is being done in this area at present, but the surface bears evidence of 
having been prospected pretty thoroughly. 
The Humboldt, at the end of the southwestern spur from Ironclad Hill, found 
no ore of consequence in its 500-foot shaft. A little of the surface slide rock, how¬ 
ever, was shipped. A vein containing much celestite is reported to course in a 
northeasterly direction from the Humboldt toward the Josie S. shaft, and to con¬ 
tinue over to the Bull Hill side. 
Some ore was taken from a shaft on the east end of the Colorado Boss claim 
on Gold Hill, across the gulch from the Humboldt, but the character of the vein 
could not be determined from examining the dump. 
A dump on the Last Chance claim, just north of the Colorado Boss, shows 
fissures in oxidized breccia with drusy quartz. It is said that no ore was found.
