MINES BETWEEN ALTMAN AND GOLDFIELD. 395 
several levels fissures branching from the main one. Intersections with the Buena 
Vista vein at its extreme northwest end, where it is not very well defined, have 
been exposed on Isabella levels 5, 9, 10, and 11. The vein is a narrow sheeted 
zone, whether in breccia, phonolite, or granite. In the breccia near the Buena Vista 
vein it widens in places to 40 feet, but is ordinarily only 2 to 4 feet in width. In 
the fresh phonolite on level 11 it consists only of one central and three lateral 
seams filled with a little crushed quartz and tetrahedrite. Partial oxidation 
continues to level 11, though tellurides prevail in the ore on both 10 and 11. Tetra¬ 
hedrite occurs in places either alone, as mentioned, or associated with calaverite; 
for instance, at the small stope on level 10 below Saunders shaft. 
ORE SHOOTS. 
The vein contains two shoots near the surface and at least two on levels 10 
and 11. The Murphy shoot, 100 feet long and pitching steeply west, reached a 
point 350 feet below the surface. The Saunders shoot had about the same hori¬ 
zontal length and pitch, but pinched 200 feet below .the surface; it yielded $40,000. 
On levels 9 and 10 a very rich shoot was found at or just east of the intersection 
with the Buena Vista vein; its length is 100 feet, and the greatest width 40 feet; 
on level 11 it had pinched in a mass of phonolite. A small body of payable ore 
was reached on level 10 below the projection of the Saunders shaft; still another 
kidney of ore was taken out on level 11 and just below it, in granite, 500 feet west 
of the Saunders shaft. 
To sum up, the shoots on this vein pitch steeply west and have an elongated 
form. The big shoot on levels 9 and 10 is clearly dependent on the intersection 
with the Buena Vista, itself locally unproductive, at a point above a mass of dense 
phonolite. The Saunders shoot lies directly east of the Pinto basalt dike. No 
law was recognized governing the position of the other shoots. 
PHARMACIST VEIN. 
The Pharmacist vein was one of those worked in early times, and a description 
of it may be found on page 194 of Penrose’s report. The vein is continuous for 
1,000 feet from the Buena Vista vein, which it intersects in its lower levels, to the 
faulted crossing of the Zenobia, a short distance west of which it seems to die out. 
On the surface the country rock is chiefly breccia, but in depth the vein at many 
places enters the Altman area of latite-phonolite. The strike is northeasterly; the 
dip averages 60° NW. Ordinarily the vein is a normal sheeted zone containing 
tellurides and quartz. There is much fluorite in the eastern part, while on the 
western side this mineral is nearly absent. Instead, open spaces filled with smoky 
comb quartz prevail. Several shoots occur, chiefly pitching steeply eastward, 
while on the Empire No. 2 westward pitch is the rule. Most of them seem to be 
connected with intersections of other veins, and one occurs at the intersection 
with the Pinto basalt dike. 
EMPIRE STATE MINE. 
The Empire State Gold Mining Company controls the eastern part of the 
Pharmacist and Empire No. 2 veins near their intersection with the Buena Vista. 
The production is at least $600,000, of which $300,000 is stated to have been taken 
out from the big stopes at the intersection just mentioned.
