398 GEOLOGY AND GOLD DEPOSITS OF THE CRIPPLE CREEK DISTRICT. 
basalt gave shipments of 2 to 3 ounce ore. A stope, 75 feet above and 60 feet below 
the level, lias been made along the dike for 70 feet. At the south end the dike is 
cut off by a fault whose direction and displacement are not shown by the develop¬ 
ments. On level 5 are two small stopes on the Pinto dike which gave $20 to $30 
ore. A stereogram of the ore bodies of the Pinto mine is shown in fig. 18 (p. 211). 
BURNS MINE. 
The Burns mine, on the Burns claim, is situated in the western part of the town 
of Altman, between the Pinto and the Pharmacist mines. It is the property of the 
Acacia Gold Mining Company. The total production probably exceeds $200,000. 
Dividends were paid in 1903. The workings consist of a vertical shaft 350 feet 
deep and a 400-foot incline winze from level 4, 350 feet below the surface. Drifts 
and crosscuts at seven levels make the total development about 3,500 feet. The 
elevation of the shaft collar is about 10,625 feet. 
So far as could be determined, latite-phonolite is the only rock encountered 
in the underground workings, though breccia appears on the surface. The Burns 
basalt dike has a course of N. 35° W. and dips steeply to the northeast. It is cut 
on all levels. 
The Pharmacist vein outcrops about 120 feet southeast of the shaft,.which it 
crosses at about level 3. The vein faults the Burns dike, the northern part of the 
dike being displaced 5 to 12 feet to the east wherever examined. 
The Pharmacist vein is a brecciated, partially oxidized zone from a few inches 
to 8 feet wide. On levels 1 and 2 it shows narrow strips of white kaolin and bands 
of manganese. On level 4 the vein is much brecciated and holds a little fluorite, 
quartz, and opal. On level 6 vug holes with crystallized smoky quartz and fluorite 
and seams of kaolin are numerous, while for some distance southwest of the winze 
a 7-inch band of fluorite and quartz occupies the center of the vein. 
The values occur chiefly in the joints and crevices between the brecciated 
fragments. In general, the tellurides have been oxidized to rusty gold, but in 
places they remain fresh. The values vary considerably. Where work is now 
being done, between levels 1 and 3, about one-half of the rock broken is saved and 
averages about $60 per ton. 
An ore shoot began at the surface southeast of the shaft and went down to 
level 2, branching at level 1. Near the surface it is 150 feet long. At level 2 each 
branch is about 50 feet long. Work is now being done below level 2, on the north¬ 
east branch. A little stoping has been done on level 4, just north of the shaft. At 
the east side of the claim a stope averaging 70 feet long and varying from 3 to 10 
feet wide reaches from 125 feet above level 4 down to level 7. It connects with 
the Pinto stope on the same vein. A large, irregular stope, 200 feet long and aver¬ 
aging 150 feet along the dip of the vein, runs from just below level 4 down nearly 
to level 6. It connects on the west with a stope in Pharmacist ground. A smaller 
stope from level 6 goes down below level 7 along the winze. 
A little ore has been taken from the Burns dike on levels 5 and 6 south of the 
Pharmacist vein. The dike seems to have no special effect on values.
