thereof reticulated or net-like ap-
pearance. Along lines of the least
strength in such a zone seams and
fissures develop as a result of the
folding and crumping of the earth's S
crust, irregular in width, of course,
and more or less variable in direction,
sometimes occurring sngly, sometimes
in groups, sometimes connected, some
times disconnected, sometimes simple,
and sometimes dividing into branches.
Solutions rising through these fissures
and seams and penetrating the ad-
jacent rocks rendered permeable by
the shearing process, deposited the
mineral-and hence the vein. 1t Is
possible, of course, to conceive of Il
very narrow sheared zone, compara-
lively uniform in width, and with lit
tie disturbance of the adjacent coun-
try. And we can also imagine very
wide zone but little sheared, with
narrow zones of more intensive shear
ing running through 1t, where conse-
quently the alteration of the country
rock and the naturalization are more
complete than in the larger, less
broken area. So through a sheared
zone we may have one master fissure
and other fissures of lesser import
ance, and seams, parallel or nearly
parallel, few feet or many feet apart
and from these several fissures ano
seams, each being originally distinct
from the others, the process of min
eralization may have gone on until
there came to be a close approach to
/ if not an actual merger of, one min
eralized zone or band with another
And of course corresponding to the
varying degrees of schistosity, the one
sometimes gradually shading into the
other, 1t Is to be expected that in some
places the naturalization will be
found with well defined limits, and in
others gradually fading into nothing
The principal minerals found in this
particular zone are lead, zinc, silver
siderte Ga form of iron), and quartz
From commercial standpoint, lead
is of first Importance, perhaps zinc
next, and then silver. The siderite
| is without commercial value.
As | understand, neither party con
tends that the ore bodies in contro
versy are physically connected with
the discovery upon which patent was
issued for any one of the claims they
are within a secondary vein. Nor, il
we assume that in the Evening Star
and Evening Star Fraction the plain
tiff has the apex Of one or more veins
| is any direct physical connection
shown between such apex and such
ore bodies. Plaintiffs only vertical
working of any Importance is the raise
| from it's drift on the No. 5 Morning
level up to it's main drift, and this is
considerable distance west of the
point where it contends the vein sep
arates into two branches. If, there
| fore, it has q vein apeXing in part ir
the Evening Star, it has made no at
/ fa1a ,ta, ,lnt,
to the ore bodies in dispute, but seeks
by means of cross cuts from and to-
ward the defendants workings, be-
tween tunnel levels and 6, to iden-
tify the mineral occurrences in the
Evening Star with the vein which il
comedies the defendants workings fol,
low upon it's downward course from
the surface of the Grouse and lroT
Crown claims to such ore bodies
without particularizing, ! am inclined
to the view that in the plaintiff!
workings, more distinctly in the Even
ing Star Fraction, vein or veins arr
disclosed. And we thus come to thu
ultimate question of whether or no
such mineral occurrences as we fint
in the easterly section of plaintiff
main drift and in the various eros
cuts which it has caused to be driven
the defendants working, are so re
lated as to constitute single vein
Enough has been said touching tn
origin and nature of the formation t
suggest the difficulty of satsfactor.
ANSWER. Generally speaking, vein
within the territorial scope of our in
auiry are characterized by the schis
tose condition Of the material AM
naturalization. So too it seems to b
agreed that, with the unimportant eX
ception of what the miner call
"horses' in the vein, an occurrenc
which is neither sheared nor mineral
lied cannot be deemed to constitute
part of the vein. But the question
whether there may be a vein wher
only one of these conditions is pres
ent finds no certain or unqualifie
answer Ore bodies in substantia
alignment upon strike and dip, thoug
separated by stretches of material bar
rem of any metal content may be re
garded as constituting a single weir
Again, in the narrow compass of
stope, admittedly embracing but on
vein, we sometimes find a bande
