in the Salt Lafe Mining Review.
During the past year, one most inn
portant factor in the permanent de
velopment of Manhattan has been
proven.
refer to the fact that for the
! length of the low ridge, crowned al
its northern point by the Big Four
property, that for over $500 feet in
4 length an area of enriched schist
! has been developed. The greatest
depth reached on the ore zone is in
the Big Four property, where a verti \
cal depth of over 500 feet has been
made.
The surface work done by the
present Commercial Mines & Milling /
company, on the Reilly Fraction es
tate, first demonstrated the great
possibilities of this section. The en-
tire top of the hill, for a width of
at least $50 feet, and probably
great deal wider, has been proven to
be susceptible to open cut mining

gold content, and is so friable, free
from shines, etc, that II can be
crushed and treated in straight

rate of Is tons to the stamp, per "a

is to these facts proven in 1913 that
