WROCKLOFF MINE. 
The Wrockloff mine, situated on the north end of the Burns claim, is also the 
property of the Acacia Gold Mining Company. The production could not be learned, 
but it has been considerable. A shaft about 750 feet deep and 2,500 feet of levels 
comprise the underground development. But little work is being done at present. 
The elevation of the shaft collar is about 10,550 feet. 
The workings are mostly in breccia made up largely of latite-phonolite frag¬ 
ments. Fifty feet southeast of the shaft on level 2 the poorly defined contact with 
latite-phonolite is seen. Both the Pinto and Burns dikes are opened in the mine. 
The former splits and branches and breaks up between levels 1 and 6. On it occur 
the principal workings of the mine. On levels 1 and 2 it is 4 to 6 feet wide, nearly 
vertical, and considerably decomposed. A cross vein which strikes S. 25° W. and 
dips 50° NW. is seen on level 2 about 100 feet north of the shaft. It is a narrow 
fissure partially filled with quartz, and carries a little fluorite and patches of kaolin. 
Three levels are opened on it from the Lyons shaft, situated 150 feet north-northeast 
from the Wrockloff shaft. 
At the intersection of this vein and the Pinto dike an ore shoot begins 25 feet 
above level 1, at a point 30 feet north of the shaft, and continues to 20 feet below 
level 4. The values are in general confined to the seams in and at the edges of the 
basalt, but above level 2 the surrounding latite-phonolite is traversed by minute 
seams parallel to the dike, which silicify the country rock and make it ore for several 
feet on each side of the dike in the neighborhood of the cross vein. The values 
decreased below level 4, and the ore soon gave out. This ore shoot was on the east 
branch of the Pinto dike. 
From level 4 to level 6 a body of ore GO feet long was taken out along the Pinto 
dike, which he^e pitches very steeply to the west. This stope is 200 feet northwest 
of the shaft, and it is said that there is no cross vein. 
On level 6 a considerable body of ore was taken out along the Pharmacist vein 
(below the Burns workings) at the point where it crosses the Burns dike. On level S 
(the bottom level) a crosscut was extended to the dike and to the Pharmacist vein 
below the deepest workings from the Burns shaft.

PHARMACIST MINE. 
INTRODUCTION. 
The Pharmacist mine, on the claim of that name, is situated at the west end 
of the town of Altman and is owned by the Pharmacist Consolidated Mining Com¬ 
pany. One of the earliest mines to be opened on Bull Hill, it attracted much 
attention by being the first to declare a dividend. The production up to January 
1, 1900, was $650,000, and of that amount $84,000 has been paid in dividends. 
Only small amounts have been produced since that date. 
The underground workings consist of an incline shaft 650 feet long, with eleven 
levels about 50 feet apart, and a vertical shaft about 600 feet deep, with six levels, 
the collar elevation being about 10,625 feet. Level 5 of the vertical shaft corre¬ 
sponds to level 10 of the incline. Connection with the Zenobia mine is established
