also visited many of the Amigo workings
on the two Cargonas. The workings
under way visited entirely, inspecting
them thoroughly and samplng the ore
bodies exposed. To thoroughly explore
the entire property would be- the work
of six month, instead of two weeks.
The workings undertaken by the
Cieneguita Copper Go. and now W. IL ad
vanced, consists of tunnels run on these
Lodges at different points, thirteen of
which have cut through the veins thus
proving the continuity of the ore bodies
along their entire length. The main
working tunnels have been run on the
north end of the Chipiona mountain,
tunnel No. being five hundred feet
from the top of the mountain and No. 2
one thousand feet below the top. Th- SO
tunnels run parallel with the lodges and
cross cuts run from these tunnels at
various distances from the entrance will
cut the ore bodies at depth of 500 feet
in tunnel No. and 1000 feet in tunnel
No. 2. Tunnel No. is the main work.

the creek bed which flows at the base of
Chipiona mountain, and will be over two
miles In length before emerging on the
other end of the group, passing through
Chiplona, Realito and Cieneguita noun
tains at depth of 1000 feet in the Chip
iona mountain and over 1000 feet in the
Realito and Cieneguita mountains. This
tunnel is sufficiently wide to permit

penetrated the mountain a distance of
$50 feet and is driving steadily forward

1000 feet beyond it's entrance At dis

another cross cut has been run to the

this point is 80 feet wide of solid sui

the Colorado. When tunnel No. 2
reaches point under the apex of Reali-
to mountain it will be 240O feet below
the surface workings. Just think of
24OO feet of "backs,' as stopping ground

60 feet in width with the ore bodies now
cut in tunnels | and 2, % and 80 feet in
width respe ,tively, with the possibilities
yet untouched in these other great
lodges the mind is staggered in an en-
deavor to calculate the Immense ore
tonnage which can be developed and ex-
tracted. Mr.. T. E. Parish, well-known
mining engineer who reported upon these
properties three years ago, when there
was little to show besides the Amigo
workings, wrote:
with plant capable of reducing 1900
tons daily [ believe the Chip
iona and Ostimuris would last fifty years
and the Tayapa will supply ore for large
lead furnaces for years to come" Be-
sides Mr.. Parish other notable mining
engineers have made reports upon these
properties, including Prof. Ell. F. Van
Furman, formerly of the Denver School
of Mines, and Mr.. Arthur Hendy, gen.
eral manager of the Copper Chief Mining
Co. of jerome, Arizona and many others.

days the ores from these two
lodges were doubtless reduced in

there are Stag dumps; and those from

likewise treated in furnaces below the
entrance to tun mel No. 2, where there
are also extensive Stag dumps and the
ruins of an old furnace. Upon the ores
now developed and ready for stopiug, in
Chipiona mountain, the Cieneguita
Copper Go. are about to commence the
work of reduction, which when once in
operation will continue without cessa-
ton, the ore reserves at the same time
being further developed as fast as men
and the latest improved machinery can
do the work. Contracts have been let
