as p PRODUCER
This well-known and Promising Property to
be operated in a Systematic Manner


maintaining expensive hosting
machinery. One continuous tun-
mel run on the vein would gain q
depth of 800 feet on the Hoosier-
boy and 1900 feet on the Scout, |
giving an average depth of about
1000 feet through the entire length
of 5000 feet. Owing to the peculiar
contour of the ground, this method
of operating and developing the
mine by tunnels driven continu-
ously on the vein has been adopted
and is being pursued by the COM
pany. The ore is a friable quartz
porphyry, carrying the gold either
free or in combination with iron
sulphurets, is easily and cheaply
mined, readily crushed, amalga-
mated, concentrated and cyanided.
So far as the ore body has been
opened, it is largly free milling;
about 80 per cent OF the values can
be saved on copper silver plates by
amalgamation, the balance or
about 40 per cent on concentrating
tables used in connection with the
copper plates at the mill thus in
surfing a high extraction of the
values in the ore at the mill. These
concentrates can either be cyan
ided at the mine or shipped to a
smclter at a small cost for trans
portation. Tests of the ore with a
view OF cyaniding at the mine have
already been made and show that
satisfactory results can be OBJ
tanned by this method of treat
ment.
Development
The work of development on the
group at present time consists as
| follows:
Hoosierboy- There are three
tunnels run on the vein, No. is
in 20 feet, all in ore, average width
over two feet; tunnel No. 2 and
lower down the mountain is in
209 feet on the vein. all in ore from
two to eight feet wide; tunnel No.
3, further down the mountain from
No. 2, is run in 400 feet, while the
full width of the assure has not
been explored in this tunnel, vet
enough of it is exposed to show
that it is over eight feet wide
Four assays made of the ore taAen
out Of this tunnel at a point where
it cut the ore were as follows: No.
| 1, 1854; No. 2, $10.l9; No. 3, S16.64
| No. !, 1913 per ton. This proves
conclusively that ore is richer in
depth than near the surface; the
point where the rich ore was found
is at a depth of about 200 feet
from the surface, following the dip
of the vein. This tunnel will be
extended until it intersects the
south end line of the Buckhorn
! ground, a distance of 800 feet
} where it will have a vertical depth
, of over 400 feet under the most
/ favorable out crop of the Hoosier-
) boy claim where it shows to be II
feet wide. There can be no ques
5 ton but that this shoot continues
! through this ground as it has al
t ready been proven that it goes ever
: deeper than the bottom of tn,
l lower tunnel, where the fissure i
= wider than it is in the upper tun
e nels and more regular. When thi
! tunnel is extended, as hcretofor,
d, indicated, it will open up a larg
z ore reserve, sufficient to keep a mil
l. in operation at a profit for severa
C years, during such time deeper tun
nels can be driven and more ex
= tensive ore bodies blocked on
,. ready for future extraction. On
;, of the good features of this min
,, is that by driving tunnels on tn
z vein and blocking outthe ore read
It for mining, nearly enough valu
:. will be received from the ore take
Il out of such tunnels to pay for dc
4 vclopment work.
r. Bucs horn-There is a cross Gu
r tn mel, cutting the vein at a dept
: OF 208 feet, and 275 feet on its dil
n From this cross cut there is a dri
Y of 70 feet on the vein towards til
ic Hoosierboy ground, thus provin
n that the ore extends through III
n Hoosierboy from the portal of tui
re mel No. to this crosscut, a di
5, lance of nearly 1000 feet; continl
al ing on south nearly 800 feet frol
h this cross cut there is an open CT
it where the vein shows both GOO
it width and good values.
)r Kcystone-There are two tut
ne nels, No. is run on the vein Il
Id feet; No. 2 is on the vein 1870 fee
es In No. 2 the ore body is from thr'
ne to eight feet wide with values
ly upwards of $40 per ton. The o
ne in tunnel No 1 is not so wide, bl
n. exceedingly rich, samples havir
