The Tramp, one mile from the Knott
is q narrow ledge. not well defined at
the surface. but increasing TO from four
TO twelve inches in width at the bottom
OF the 60 foot shaft. An excellent ar
rastra is situated three miles from the
mine, at which the ore is delivered by
pack-traip at an expense of s. per ton.
The average yield is from $50 to SG5;
the production of ore is. how ever, small.
The Charity, two miles south of War
rens, is owned and operated by g.
Riebold. 1t has been prospected by
tunnels to depth of 200 feet, the lowest
tunnel being 800 feet in length. The
present workings are confined to the
upper levels. The reduction works CON
sist of five-stamp battery at the mouth
of the tunnel. There is "A large amount
of low-grade ere with rich pockets here
and there. The average yield is from
IS to $l2 per ton, though selected lots
have reached as high as 81 800 per ton.
The Mayfower is recent discovery,
and a mine of considerable promise.
The vein is from six inches to two feet
in width, and the ore pays from SIT to
$40 per ton. Both the ore and country
rock are soft and easily worked, and the
ledge lies favorably for development
The ore is worked in its own mill.
The Rescue mine is near Warrens and
has been the most extensively develop
ed mine of any in the district. A tunnel
taps the vein at depth of 1873 feet. at
which point shaft extends to the sur
face. The hosting works are of suf-
fcient capacity to sink to depth of 500
or 900 feet below the tunnel leve'; the
shaft is already $50 feet lower, and two
levels are opened. A fve-stamp mill il
erected at the mouth of the tunnel The
ore chimney is from 250 to 800 feet in
length, and the ore is all taken out
above the tunnel. The first 60 feet be-
low the tunnel is also exhausted, and
the next level has the main shaft sunk
and the level run about 20 feet, at which
point it is in ore. The total yield of the
mine has been from $50. 600 to 500 900.
The yield per ton from the different
jedges of the Warren district has varied
greatly. Large quantities of rock from
the Rescue paid from $50 to $50 per ton.
Selected ore from the Charity paid from
$40 TO $50. and from the Scott rs high as
$50 per ton. The Keystone ore paid
quite uniformly from $50 to sos, and on
the other hand, some lots from other
lodges scarcely paid for working.
The average yield of ore from this
district is not readily estimated. The
processes of extraction of the precious
metals have been ofthe simplest charac-
ter; at first arrastras were used, then
stamps with copper plates of limited
extent, and at present the arrastra fol-
lows the battery with blanket washings
saved for future treatment. Assays OF
tailiugs have rarely been made, and it
is not easy to estimate the percentage OF
gold and silver extracted.
The ore is generally calcined prior to
crushing. and the returns show thar
more silver is saved by this preparatory
treatment. Bullion from calcined ore is
usually from 300 to 500 fine, while that
from the raw material is 900 to $50 fine
The gold from placer mines varies very
much in tineness. That from the small
gulches and heads of the streams is from
1925 to .615 fine; in the main creek from
ZOO to .760 fine, and is the common cur
rency at Sl4 per ounce. A great extent
OF ground has been worked along Sal
mon River, principally by rockers and
other primitive appliances; the gold is
usually in small particles, known as
hour gold, though sometimes found in
scales; it is current at Sl6 per ounce, be-
ing from 800 to S25 fine.
Near John Days Creek few bars of
limited extent have yielded coarse gold,
and nuggets of from So to Sl5 each. of
high grade, over $50 fine, and current
at $3.50 per ounce.
The yield from Idaho County can only
be approximately stated. Five Chinese
companies in Warrens take out more
than half the gold of the camp. From
diligent Inquiry made of the principal
members. the following estimate may be
stated as nearly correct:
