THE VEINS AND THEIR ORE. 
v 
The vein system in this mine is somewhat complicated. The present descrip¬ 
tion follows the views of Mr. F. G. Willis, who some time ago undertook a careful 
geological examination; figs. 49 and 50 illustrate these relations. Near the surface 
a principal vein, pretty well defined and nearly vertical, called the “C” vein, 
seems to pass from the Findley shaft close by the Minnie Bell and Tompkins shaft 
to the main shaft, and thence down to the Vaughn or Glorieta shaft across bv the 
Vindicator No. 2 shaft, a 
total distance of 1,300 feet, 
with a strike of N. 40° W. 
Three or four hundred feet 
below the surface two other 
veins appear on the north¬ 
east side of the shaft, while 
the “C” vein, with more 
decided southwesterly dip, 
crosses the big dike. Another 
vein, called the “D,” fol¬ 
lows the northeastern side 
of this dike. On level 10 
three veins are exposed— 
the Winze vein, the “ D” 
vein, and the “B v vein. 
The “ A” vein is known only 
on levels 3, 4, and 5 (fig. 54). 
The veins show the usual 
structure and consist of sev¬ 
eral tight seams, in places 
separating brecciated mate¬ 
rial, or of a central seam, 
with small vug holes coated 
with quartz and fluorite, 
surrounded by several less 
distinct cracks. Dolomitic 
carbonates and pyrite are 
disseminated through the rock in the vein at many places, also outside of it, and 
crystallized carbonates may often be seen coating the seams. 
The stopes on the “D” vein along the dike on level 4, north of the shaft, 
showed a very much crushed, nonoxidized dark-green breccia, in which much 
replacement by fluorite and pyrite, apparently also by calaverite, has taken place. 
The vein was stoped 2 feet wide and all of the material sacked. The “A” vein 
on this level is 3 feet wide in the pay shoot, with about six parallel and oxidized 
seams. On level 7 veins “C” and “D” lie close together, and “C” appears to 
cross the dike, which contains small streaks of stibnite and galena. The veins are 
partly oxidized on this level.
