The Quapaw or Lincolncille camp is
situated near the Kansas line and a
flew miles east of Quapaw. The pro
ductive area is approximately two
square miles in extent. The ores are
principally in blanket ground of ebert
breccia, near the horizon of the Short
Creek oolite member of the Boone
chart. Tlere are several solution
patches" which have been partially
mined out The greater portion of the
workings have been at depth of from
70 to 80 feet. The ores are sphalterite
and galena in varying proportions.
About one-third of the uptput of the
Kansas City-Quapaw told Nilsson
mine) in galena, while the output OF
the Petersburg Land & Mining Co.
(old NJ, X. & T. mine) Immediately to
the north, is all sphalerite.
Deposits Irregular.
The sphalerite and galena occur ir-
regularly distributed in crevices and
in cracks in the ebert breccia. Oxidized
ores. principally zinc silicate, chiefly
in those in the east and southeast por-
tions of the camp.
The blanket-ground formation is OF
low grade, sledom averaging over
per cent of concentrates, but the con
centrates are high grade, averaging 81
per cent of metallic zinc. The dirt

part of the camp, which are in open
ground at a depth of about 100 feet
averaging to 10 per cent of concen
trates of hign grade. While there is
fair head of water, it is controlled witt
comparative ease. The water huetu
ates with the wet and dry seasons, ant
is not charged with hydrogen sulphids
gas. as is the case with the water il
the deeper workings in the Miam
camp.
Four Steam Plants.
The Quapaw camp opened In 1905
and development was rapid until th'
financial depression of 1907. At th'
close of the latter year there were q
steam concentrating plants and hand
liz outfits in operation. The law prices
of ore generally prevailing since 1870
have prevented the profitable working
of the low-grade blanket-ground ores
except where the mines had larg'
openings in the ore-body and large ca
pacity mills. Consequently there ha
been practically no new development
since 1907. Several of the mills hav'
been removed and many have stoo'
idle the greater portion of the time
There are now twelve steam concen
trating plants and few hand jigs
Only four of the steam plants are il
operation.
The Kansas City-Quapaw compan.
has a 2O0-ton mill on the old Mission
lease, at the extreme west end OF tn
camp, and the Petersburg Land 4
Mining Co., 400-ton mill on the oil
M, X. & t. and Ward leases, imme
diately to the north. These mines ar
in the typical hard-blanket ground, tn
ore occurring in the chart with praC
tically no calcite or dolomite. A fac
of about 20 feet is worked in bot
mines.
Two Levels at Big Jack.
The Big Jack Mining company opel
ates a 10O-ton mill to the east of tn
old Mission mine. They have tw
levels, the upper one at 80 feet, in har
ground. and lower level at 107 fee
which is softer and more open, so tha
timbering is required to support tn
roof. Calcite and dolomite occur wit
the sphalerite and galena, which ar
in the proportion of 81 in the lowe
body. The lower ore seems to be
run IA feet in thickness and "a ZEE
wide, dipping slightly to the west. Th
ore from the upper run gives pc
