frequent occurrence in mining and
when the miner thinks two veins are
running together he follows in order to
get the benefit of the greater enrichment
which ne invariably finds at the point
of intersection. In this mine there are
almost countless instances of the inter-
sections and the consequent enrich
ment. The assures have been followed
with more care since the beginning Of
this litigation than they were preyl-
ously"
At this point the afternoon recess
was taken.
MIR. Heinze was still under direct ex-
animation at the opening of the after
noon session. He showed raise which
was started from the 134-foot level
which runs from the Michael Dewitt
raise easterly through the east fault.
This raise was started by the plaintiffs,
but abandoned. The defendants then
took hold Of the upraise and followed
the streak until it reached between the
vertical lines of the Rarus, and then
stopped The plaintiffs then once more
continued the work, reaching the hang
ing wall The effect is two raises, both
practically made by the plaintiffs.
which diyerge. One was raised or
streak dipping to the north and the
other on a streak dipping to the souun.
Mr. Heinze described in detail the
workings done by the plaintiffs and by
the defendants for the purposes OF the
suit. and described the raises and
streaks, etc, and their relation as
showing the apex 10 be on RaruS
ground The Michael Dewitt shaft has
slight angle. Almost as soon as the
workings are left a south dipper is fol-
lowed going west until north dipper
is met At the bend the country is
more broken up and the plaintiffs con-
tinued work to the north, reaching an
other south dipper. They followed this
until they met another bend, and fol-
lowed the north dipper until they
reached - A raise. The witness
claimed that instead of being a drift
on one streak the workings of the
plaintiffs are in reality croSS-cut
passing through and for some space
with several different streaks. The
witness exhibited some rock specimens
from the mine showing the copper
bearing Streaks running in various d.
rections. These streaks are not COM
mercially valuable at present, but prob
ably will become so as costs of reduc-
ton are lowered. In the Atlantic mine
of Michigan ore giving 75-100 of / per
cent of copper is reduced, and the wit
ness believed that in time all this
rock In the lode could be reduced with
profit On descending upon the Vari-
Gus pay streaks it is found that the
middle streak has so far approached
the southern streak as To make them
one ore body without any intervening
rock such as separates them on the up
per levels.
Have you investigated the ore bod
les sufficiently to ascertain where Is the
apex of these ore bodies?"
L have examined the Rarus and the
Johnston both below and on the sur
face and am of the opinion that the
apex enters the Johnston end line at
shaft No. and proceeds in an easter
