All of

.~
claim. These consist of one tunnel (fig.3) and two shafts
(figs. 4-7)which, judging from the volume of dump material,
contain
the
majority
of
development.
The tunnelis 54 ft. in,length and was apparently driven
prior to 1914 to test a narrow vein structure.
It was abandoned
when the vein proved to
be uneconomic. The two shafts are open,
but
dueto
their
condition
were
not
entered.
Shaft no. 7 (fig.6), also known as the "tunnel" shaft, was
the center of most of the early (19.10-1916) development. This
shaft was164 ft~. deep, nearly vertical, with levels
65 at
ft.
(the 60 ft. level) andat or near the bottom (the 150 ft. level).
The shaft is presently open
to 104 ft. below the collar;
it is
0
caved at this point and has been, apparently, for some time.
This
cavingis probably
indicative
in
part
of stoping
above
the
150 ft. level. Heavy ground, however, is known to have been
encountered in this shaft."
Shaft no. 1 (fig. 7), also known as the "lower" shaft;.was,
in 1914, 80 ft. deep with short drifts
at the bottom driven to
the east and west. This shaft, inclined 265" to the southeast,
was the center of activity during the later (1920-37) period.
During this time,it was extended below the 100 ft. level where,
at 103 ft., a drift was driven to the west a distance
of 208 ft.
and another to the east 25 ft.

presently amount to $150.00/ton). To be made economic,

will be foundon the Battleship group to finance construction
of a suitable mill. Thus the Battleship group by itself
appears to have little present value. The economic picture could
