The Columbia Company.

Inc COluUlDld L luuHel % Miieo w.
comprising seven claims located in
Lincoln Mining district, have just had
published a fine prospectus which
treats very minutely of the companys
inerests. In developing the property
of the company, which is composed
principally of Central City people, it
will confine itself pretty much to
adt tunnels driven on the veins
which will open UP the ore bodies in
in the shortest possible time, such
system Is directly in line with the
Gre bodies. Several bodies of ore are
already opened. The Ruby's adit tun-
mel, the objective point being the
Mary B. vein, which crosses the line
Of the Ruby Trust tunnel distance
of 800 feet from the portal. The tun-
mel is in 400 feet. At the point OF
intersection with the Mary B.,a depth
of 5000 feet viii have been gained
affording a fine opportunity for prof
liable production at the conjunction
of veins. The vein is from two and
half to four feet wide with well-defin-
ed walls enclosing the quartz carry
ing the mineral.
| The Mary B. has a shaft 60 feet
deep with good ore in a distance of
225 feet. The surface openings show
strong vein with four feet of vein
matter
The Columbia Extension has vein
four feet wide, and the Columbia
Cross has three shallow shafts show
! ing the vein TO be fully three feet
wide. Further development will be by
drift from the level of the Colum-
bia tunnel.
The Bunney has one of the strong
est veins in that section, showing
four feet between well-defined walls.
! The Annie has opened the same
vein as that contained in the Ruby
Trust OF which It is he southern ex-
tension. This vein will be cut by the
Columbia tunnel at considerable depth:
Each of the properties can be read
/ lily developed by tunnels, the contour
of the surface being such as to pre-
sent favorable conditions for indivi-
dual development. The good ore on
the surface and in the openings gives
premise of large quantities of ship
ping ore with depth,
There is an eight-inch pay streak
in the Ruby Trust that assays $50
per ton in gold, silver and copper.
/ Besides the smelling ore there is
from one and one-half to two feet OF
milling ore of good quality. Two hun
dred ana fifty feet further on the line
of this tunnel there is another ore
shoot uncovered for a distance o!
smelling and from three to four feet
of milling ore of a good grade. The
other properties show equally as well
as to ore bodies and their values
Considering the comparatively small
amount of development the company
certainly has a good showing. Empha
sis is laid on the fact as to the econ
omy OF developing the property by
tunnel, as compared with the cost OF
mining by shaft.
1t is part of the plan OF the COM
pany to build mill for the treatment
OF its low-grade ores at the earliest
possible moment. Enough ore being
exposed to warrant such an enter.
