Anomaly M

Anomaly M (figs. 37 and 38), about 800 feet south of anomaly J, is the north
part of a broad, anomalous area. On an east-west axis Z-Z', the anomalous area is
about 700 feet wide between the margins of resistivity contour 10,000 ohm-cm,
Within this contour are 2 minimum-resistivity areas outlined by 5,000-ohm-cm, con-
tours, Three test holes, GB-46, GB-50, and GB-42, along section Z-Z', showed shale
averaging 57 feet in thickness extending horizontally at least 600 feet; its full
extent was not determined, The shale is highly shattered and weathered, intermixed
with chert boulders, and evidently has slumped into the underlying formations, which
show extensive solution action and structural deformation, Strong currents of water
prevented complete recovery of drill cuttings, The log of hole GB-42 shows traces
of sphalerite just above the Grand Falls horizon, The profile of the shale-limestone
contact generally corresponds to the resistivity profile,

SUMMARY OF RESULTS OF DRILLING

Where enough drill holes were bored to provide a full cross section of an anom-
aly, it was found that resistivity contours closely defined the margins of the shale
area and that resistivity profiles indicated, to a reasonable degree of similarity,
the configuration of the shale-limestone contact,

Nine of the 21 low-resistivity anomalies tested by churn drilling contained ore
averaging 1.50 percent or more combined zinc and lead. Generally, the ore was de-
posited in the flanks of limestone sinks and in the limestone below the shale, al-
though in a few places small quantities of zinc and lead minerals were found in
limestone and chert breccia within the shale,

Pertinent data on the 22 anomalies tested by drilling are provided in table 4
and disclose that, of 13 anomalies with a minimum resistivity of 2,500 to 7,500
ohm-cm, and a maximum resistivity of 10,000 to 15,000 ohm-cm., 8 are mineralized and
represent shale slumpages (anomalies B, C, D, J, N, Peacock, Badger, and Colorado) ;
1 anomaly (A), representing undisturbed shale in a limestone depression, is miner-
alized; and in 4 anomalies (E, M. H, and P) no mineralization was found, Of the
remaining 9 anomalies tested, 4 with resistivity ranging between 10,000 to 20,000
ohm-cm, showed small shale slumps and minor mineralization; 4 anomalies with re-
sistivity ranging between 10,000 and 12,500 ohm-cm, were shale outliers generally
in normal position, with minor deformation and mineralization; and 1 anomaly (1)
with a resistivity range of 20,000 to 60,000 ohm-cm, represented limestone at or
near the surface,

CONCLUSIONS

Electrical-resistivity techniques were successful in locating and defining
shallow shale deposits in limestone structures under concealing overburden,

Seismic measurements located and partly defined some of the larger sinks con-
taining slumped shale masses but did not adequately depict the configuration of the
underlying limestone surface,,

Close relationship exists between the geology and structure of underlying for-
mations and resistivity anomalies disclosed by surface measurements, Anomalies with
minimum resistivity from 2,500 to 7,500 ohm-cm, indicate shale deposits in sink holes
in zones of structural deformation, Those anomalies with minimum resistivity above
7,500 ohm-cm, generally indicate relatively firm shale in areas of minor structural
deformation,

Eight test holes within the anomalous area disclosed Cherokee shale lying in a
sink in the Boone limestone beneath 5 to 25 feet of residual deposits, The shale is
intensely altered and shattered, shows slickensides and is mixed with clay, selvage,
and numerous limestone and chert boulders, The margins of the shale area are defined
by the 10,000-ohm-cm, contour; hole GB-71 near the center of the anomaly, where mini-
mum resistivity is 5,000 ohm-cm., penetrated a maximum thickness of 112 feet of
shale, The underlying Boone limestone shows intense structural deformation into the
Grand Falls member, and the overlying shale has collapsed into solution caverns in
the Limestone,

The profile of the shale-limestone contact conforms to the resistivity profile;
outside the shale area, resistivity increases rapidly as the limestone nears the
surface, Test holes GB-20 and GB-21 on the east flank of the sink show zinc and
lead minerals in the Warsaw and Keokuk limestone; hole GB-21 intersected a 7-1/2-
foot section of ore from 150 to 157-1/2 feet averaging 1.55 percent zinc and hole
GB-20 shows traces of zinc and lead minerals from 70 to 120 feet,

Anomaly D

Anomaly D (figs, 15 and 16) is an oval area with a narrow elongation extending
northwest into anomaly C, to which it is evidently connected, The resistivity range
is the same in both anomalies. Five test holes were drilled over a distance of 500
feet on an east-west section F-F', and 5 additional holes were drilled over a dis-
tance of about 500 feet on a north-south section G-G', The drill holes disclosed
shale lying in a sink hole in the Boone limestone, The shale is highly shattered
and altered, shows slickensides, and is mixed with considerable black clay, selvage,
chert, and limestone boulders, The underlying Boone limestone shows intense solu-
tion action and structural deformation into the Reeds Spring member, It is evident
that dissolution of the limestone formed caverns into which the Cherokee shale
collapsed,

The margin of the top of the shale under 5 to 30 feet of residual deposits is
well defined by the 10,000-ohm-cm, contour; and a maximum shale thickness of 120
feet, penetrated in hole GB-12, corresponds to minimum resistivity of 2,500 ohm-cm,
The profile of the shale-limestone contact conforms to the resistivity profile
within the depth limit of resistivity measurements, Hole GB-24, on the south flank
of the limestone sink, intersected a 7-1/2-foot ore section from 110 to 117-1/2
feet that averaged 0,39 percent zinc and 1,29 percent lead, Traces of zinc and
lead minerals showed in four other test holes,

Anomalies E and Badger

Anomalies E and Badger (figs. 17 and 18) on the west bank of Spring River occur
on opposite sides of the junction of the alluvial plain and rolling prairie land,
the surface elevation of anomaly E being about 64 feet higher than the Badger anomaly.
The anomalies are roughly oval, with northwest-southeast elongations, and have simi-
lar ranges in resistivity, Six test holes were drilled along section H-H' through
the long axes of the anomalies, Holes GB-91, GB-89, and GB-23 on anomaly E showed a
length of about 1,050 feet of shale within the 10,000-ohm-cm, contour and an average
shale thickness of 33 feet, beneath 5 to 20 feet of surface residual deposits; no
structural deformation is evident, Drill holes GB-93, GB-95, and GB-30 on the Badger
anomaly within the 10,000-ohm-cm, contour showed a shale length of 700 feet or more
and a maximum shale thickness of 20 feet, below 20 feet of residual deposits, The
test drilling did not suffice to delimit fully the horizontal extent of the shale.

a 37-1/2-foot ore section from 42-1/2 to 80 feet, averaging 1.71 percent zinc and
0.05 percent lead. Hole GB-43 intersected a 7-1/2-foot ore section between 112-1/2
and 120 feet that averaged 1,71 percent zinc and 0,02 percent lead, The profiles of
the shale-limestone contact correspond to the resistivity profile,

Arena Anomaly

Arena anomaly (figs, 25 and 26) includes the Arena mine and covers two areas of
low resistivity - a small, oval, southern area and a larger, irregular, northern
area separated by a high-resistivity strip, The logs of several holes drilled by
mining companies were incomplete, and the outline of the shale in the larger area
was not fully disclosed, Three Bureau test holes - GB-67, GB-68, and GB-69 - on
east-west section Q-Q' and holes 90, M-31, M-26, 10, and 13 near northeast-southwest
section P-P' define a small shale deposit in the southern anomaly about 290 feet
long within the 17,500-ohm-cm, contour, Test hole GB-67, in the center of the anom-
aly, corresponding to minimum resistivity of 10,000 ohm-cm., disclosed a maximum
shale thickness of 49 feet below 3 feet of residual deposits, The shale is fractured
and altered and evidently has slumped into a solution cavern in the underlying de-
formed limestone, The profile of the shale-limestone contact conforms with the re-
sistivity profile, Traces of zinc and lead minerals are evident in and near the
Grand Falls horizon, where a little mining was done in the early days of the camp,

The resistivity of this shale mass, ranging from 10,000 to 17,500 ohm-cm,, is
much higher than that of the shale-induced anomalies in the central part of the
project area, Logs of the drill holes provide no data to account for the higher
resistivity, The northern anomaly probably indicates an area of fractured ground
and water-filled crevices referred to in the logs of holes 40, 41, M-21, and 14,

Anomaly K

Anomaly K (figs. 27 and 28), about 700 feet west of the Arena mine, is an oval
area with resistivity ranging from 17,500 to 10,000 ohm-cm, Four test holes on
east-west section R-R' through the short axis of the anomaly disclosed a shale mass
at least 260 feet wide within the 17,500-ohm-cm, contour, Hole GB-37 in the center
of the anomaly, within minimum resistivity contour 10,000 ohm-cm,, penetrated a
maximum shale thickness of 43 feet below 15 feet of residual deposits, Data obtained
from test drilling indicate that the shale has slumped into a troughlike depression
in the underlying limestone, The profile of the shale-limestone contact corresponds
with the resistivity profile, Traces of zinc and lead minerals are evident through
the Grand Falls formation,

Big Cave Anomaly

Big Cave anomaly (figs, 29 and 30) includes one large and several small anom-
alous areas in the vicinity of the Big Cave mine, Four of these anomalies, with
minimum resistivity ranging from 10,000 to 12,500 ohm-cm,, tested by 1 drill hole
each, contained small shale deposits in depressions in the underlying limestone as
indicated by the resistivity contours, Hole GB-86 on north-south section T-T' pene-
trated 40 feet of well-bedded shale below 10 feet of residual deposits in one of the
smaller anomalies, Hole GB-61, near the west end of the large anomaly, penetrated a
shale thickness of 25 feet within the 10,000-ohm-cm, contour; and hole GB-81, within
a 12,500-ohm-cm, anomaly on the northwest end of section S-S', penetrated 20 feet of
firm shale below 10 feet of residual deposits, On the southeast end of section S-S'
drill hole GB-90, within a minimum resistivity contour of 10,000 ohm-cm,, disclosed
25 feet of compact shale below 15 feet of residual deposits, As in the other

INTRODUCTION

Geophysical surveys have been utilized to some extent by private industry in
the Tri-State zinc-lead district to indicate areas and zones of structural deforma-
tion as guides to directing exploratory drilling for ore deposits, Data obtained
from these surveys, however, and their correlation with geological conditions dis-
closed by appropriate drilling, in instances where such correlation has been at-
tempted, have not been published, hence are not available to other persons or mining
firms concerned with planning explorations in the district,

In 1941-42, the State Geological Survey of Kansas and the University of Kansas
Engineering Experiment Station jointly studied the use of various geophysical tech-
niques in the Kansas part of the district, where a thick mantle of shale overlies
the ore-bearing limestone and chert formations, The results of the investigations
are described by J, J. Jakosky and others in State Geological Survey of Kansas
Bulletin 44, which refers to previous geophysical investigations in the district by
the Missouri Bureau of Mines and Geology, the Missouri School of Mines, and others,

The purpose of most of these investigations was to develop geophysical tech-
niques, the use of which would reduce overall exploration costs by differentiating
between favorable and unfavorable geologic structures, thus confining exploratory
drilling to predetermined zones of possible ore deposition,

To further this objective, from October 1950 to June 1953 the Federal Geological
Survey and the Federal Bureau of Mines cooperated in an investigation designed to
evaluate the practicability of electrical-resistivity and seismic methods for indi-
cating zones of structural deformation in rock formations concealed by a relatively
thin overburden of alluvium and residuum, The site selected comprised 2,206 acres
in eastern Cherokee County, Kans., bordering Missouri, The area, three-fifths of
which is covered by the flood plain of Spring River, surrounds the Badger-Peacock
camp and adjacent zinc mines and prospects,

Geologic conditions on the site, which borders the east edge of the thick mantle
of shale overlying the ore-bearing formations in the Kansas-Oklahoma part of the Tri-
State district, are similar to those in the Missouri part of the district, wherein
erosion has removed the shale cover, except for scattered remnants or masses that
have subsided into limestone sinks,

ACKNOWLEDGMENTS

The cooperation of the various landowners and lessees is gratefully acknowledged,
Thanks are due especially to L, W. Goings, who provided many drill-hole logs and maps
of mine workings; and to Gill Montgomery, manager, Minerva Mines, Inc., who provided
logs of recent drilling in the area, Otto Ruhl, former Bureau of Mines engineer,
supplied valuable information and assistance,

Field work by the Bureau of Mines was under the general supervision of L, T.
McElvenny, chief of the Mining Branch, Minerals Technology Division, Region VI,
Rolla, Mo, L. C, Brichta was project engineer, K. L, Cook supervised the electri-
cal-resistivity survey, and W, E, Davis was in charge of the seismic tests for the
Geophysics Branch, Geological Survey.


PREFACE

The Bureau of Mines and Geological Survey in 1950-53 jointly
investigated and correlated certain geophysical anomalies with
geologic structures revealed by churn drilling at and in the vicin-
ity of the Badger-Peacock camp, Cherokee County, Kans,, to evaluate
geophysical methods as an auxiliary to churn drilling for lead and
zinc deposits, The Federal Geological Survey did the geophysical
research, and technical papers concerning that phase have been
published or are in preparation by that agency.

The Bureau of Mines tested all geophysical anomalies against
the results of churn drilling, This report of investigations pre-
sents the geophysical anomalies and the Bureau evaluation thereof,

based on churn-drilling results,

anomalies, the underlying limestone is generally hard and well bedded. The profiles
of the shale-limestone contacts conform in part to the resistivity profiles, The
logs of all the drill holes show traces of zinc and lead minerals in the Grand Falls
formation; some mining has been done at this horizon,

Anomaly P

Anomaly P (figs. 31 and 32) is a small, irregular area about 1,000 feet north-
east of the Big Cave mine, It lies near the northwest end of a large, elongated,
northwest~southeast-trending, anomalous area, Minimum resistivity at the center
of the anomaly is 7,500 ohm-cm, Two test holes were drilled - hole GB-62 on section
U-U', within the 7,500-ohm-cm, contour, penetrated 8 feet of shale below 10 feet of
residual deposits; and hole GB-88, on section V-V', on the 10,000-ohm-cm, contour,
penetrated 5 feet of shale below 10 feet of residual deposits, The drilling did not
suffice to define fully the horizontal extent of the shale area but does indicate a
relatively thin shale deposit lying in normal sequence in a shallow erosional de-
pression in the underlying limestone, No zinc or lead mineralization was evident in
either hole,

Anomaly Q

Anomaly Q (figs. 33 and 34) is about 700 feet southeast of anomaly P in the cen-
tral part of the same general anomalous area trending northwest-southeast, The logs
of test holes GB-74 and GB-73 on east-west section W-W' disclose a width of 200 feet
of shale within the margins of the 12,500-ohm-cm, contour; hole GB-63 penetrated a
maximum shale thickness of 48 feet, corresponding to minimum resistivity of 10,000
ohm-cm, The shale is shattered, altered, and intermixed with limestone and chert
boulders and evidently has slumped into a solution channel in the limestone, The
profile of the shale-limestone contact conforms in part with the resistivity profile,
The log of hole GB-63 showed traces of zinc and lead minerals in the Grand Falls
chert,

Anomalies L_ and Colorado

Anomalies L and Colorado (figs, 35 and 36) are in the Colorado mine area, where
alluvial deposits east of Spring River feather out onto Warsaw limestone, Within
this area are 3 small anomalies with resistivity ranging between 7,500 and 15,000
ohm-cm, The Colorado anomaly, near the northwest end of section Y-Y', was tested by
hole GB-94 in the center of the 7,500-ohm-cm, contour, The log of the hole shows 10
feet of shale, intermixed with limestone and chert boulders, beneath 35 feet of al-
luvium; the shale has evidently slumped into a solution channel in the open and al-
tered limestone and chert, The log of the hole also shows a 62-1/2 foot ore section
from 105 to 167-1/2 feet in limestone and chert that averaged 1.95 percent zinc and
0.02 percent lead, Anomaly L is a high-resistivity (20,000- to 60,000-ohm-cm.) area
where the Warsaw limestone crops out, Test hole GB-38 on section Y-Y' 800 feet east
of hole GB-94 was drilled near maximum resistivity contour 60,000 ohm-cm, to ascer-
tain the cause of the high resistivity. The log of the hole showed firm, well-bedded
limestone and chert strata from the surface to the Grand Falls horizon. Traces of
sphalerite and galena were evident in the Grand Falls formation, The profile of the
bottom of the shale and the top of the limestone conform, in part, to the resistivity
profiles, but too few drill-hole data are available for close correlation,

From 1905 to 1910 Peacock Valley Mining Co, drilled 41 holes aggregating about
8,100 feet of bore on the Big Cave and Arena mine areas in secs. 13 and 14, exploring
the sheet-ground horizon, Logs of 40 of the holes are available, and the pertinent
data on the holes are summarized in table 7.

In 1923 Barnsdall Zinc Co, drilled 15 holes aggregating 3,080 feet of bore on
the Kansas and Missouri Land & Mining Co, holdings in secs, 23 and 24, in which the
Badger, Rosebud, and part of the Haystack mines are situated, Pertinent data on the
holes are summarized in table 8. Most of the logs indicate that the upper Keokuk
beds were highly altered and difficult to identify; submarginal zinc-lead ore is
evident in and above the Grand Falls horizon.

During 1925 and 1926 Hubbard Mining Co, drilled 51 holes aggregating approxi-
mately 6,290 feet of bore on the Williams land in sec, 23, The logs of only 47
holes are available, Pertinent data on the holes are summarized in table 9, The
drilling disclosed two small sinkhole structures, where a little mining has been
done. The logs of the holes and statements of individuals who did some of the mining
indicate that the ore occurred in small, sporadic concentrations in open ground be-
tween the shale and the top of the Grand Falls chert, Nine holes drilled through
the Grand Falls chert showed small quantities of ore minerals; one hole (No. 46),
drilled to 328 feet in depth, shows traces of zinc and lead in the Fern Glen
formation,

During 1946 Carson Mining & Milling Co, drilled 11 shallow holes, aggregating
652 feet of bore, to determine the thickness of overburden and to test the upper
formations for shallow ore to the south and west of the open pit at the Peacock mine
in sec, 24, Below the residual overburden the logs showed shale, fractured and
brecciated limestone, flint, and "selvage" containing minor zinc-lead mineralization,
Pertinent data on the holes are summarized in table 10.

In 1951 Minerva Mines, Inc, drilled 32 holes aggregating 4,721 feet of bore on
several mine tracts to check previous drilling and to explore for shallow deposits
suitable for open-pit mining, Eighteen holes were drilled on the Peacock 40 to test
the areas around formerly productive mines, Most of the holes showed only minor
zinc-lead mineralization in the fractured and altered rock, Seven holes were drilled
in the Cicinnati-mine area, three of which intersected ore southeast of the mine
workings in the sheet-ground horizon, Two holes in the Arena mine area intersected
submarginal ore in the sheet ground, In the SE1/4SE1/4 sec, 14, 1 of 3 test holes
intersected a 10-foot ore section in the sheet ground averaging 2.42 percent zinc.
The 32 holes are shown on figure 3 by numbers prefixed with the letter M. Pertinent
nent data on the holes are summarized in table ll.

Copies of the original logs of the holes drilled by the above companies are in
the files of the Bureau of Mines at Joplin, Mo.

EXPLORATION RESEARCH BY FEDERAL AGENCIES

The Badger-Peacock camp and vicinity was selected as a suitable site for the
investigations, because it is similar, topographically and geologically, to much of
the western part of the Tri-State district, Moreover, from records of past mining
and exploration drilling, .considerable information was available on the ore occur-
rences and geological conditions that would facilitate correlation of geophysical
data obtained from surface measurements with structural and lithologic data
disclosed by drilling.

Anomaly A

Anomaly A (figs. 11 and 12) covers part of a broad, elongated, low-resistivity
area with the short east-west axis extending along section A-A' for 930 feet within
the 12,500-ohm-cm, contour. Minimum resistivity contours of 5,000 ohm-cm. enclose
the wide central area, Five test holes (GB-13 to GB-17) disclosed compact, bedded
compact, bedded Cherokee shale lying in normal position in an erosional channel in
the limestone, The east-west limits of the shale were well defined by drill holes
GB-14 and GB-17 and correspond closely with resistivity contour 12,500 ohm-cm,
where the limestone nears the surface, A maximum shale thickness of 40 feet was
penetrated in hole GB-13 near the center of the anomaly, Remnants of Chester lime-
stone cover the flanks of the channel between the shale and the Boone limestone,
The profile of the shale-limestone contact generally corresponds with the resisti-
vity profile,

Test hole GB-17, in the east flank of the limestone channel, penetrated a 10-
foot section of ore from 25 to 35 feet that averaged 3,58 percent zinc and 0.03 per-
cent lead, Traces of zinc and lead minerals were encountered over considerable in-
tervals in the limestone in all the drill holes,

Anomaly B

Anomaly B (figs, 11 and 12), an oval area west of anomaly A that includes the
productive workings of the Hubbard Mining Co., also has its short axis on section
A-A' and a range in resistivity similar to anomaly A, Within the 10,000-ohm-cm,
contour and between test holes GB-4 and GB-7 the short axis is about 440 feet long;
the long north-south axis within the 10,000-ohm-cm, contour is indicated to be about
630 feet, Ten holes were drilled to test the anomaly, 7 of which disclosed a de-
posit of broken, bouldery shale beneath 5 to 20 feet of residual material, Drill
holes GB-4 and GB-7 defined the east-west margins of the shale, corresponding with
resistivity contour 10,000 ohm-cm,, and hole GB-5 penetrated a maximum shale thick-
ness of 85 feet near the center of the anomaly, corresponding to a minimum resistiv-
ity of 5,000 ohm-cm, The shale contains fragments of coal, clay, and selvage and
evidently has slumped into a solution cavern in limestone,

In a shallow shaft 150 feet south of hole GB-18, broken shale beds with a steep
north dip are exposed, and the limestone and chert underlying the shale show exten-
sive alteration, solution action, and structural deformation that has caused slumpage
of the shale,

The profile of the shale-limestone contact generally conforms with the resistiv-
ity profile, within the limits of penetration of resistivity measurements, Several
ore holes have been drilled by mining companies in the eastern part of this anomalous
area (fig, 3), most of which were in the east flank of the limestone sink, The logs
of two of these holes near section A-A' - 9 and 13 (fig. 11) - show a 26-foot ore
section averaging 3,35 percent zinc and a 25-foot ore section averaging 2.36 percent
combined zinc and lead, respectively, in the Boone limestone, Test hole GB-18, be-
tween holes 9 and 13, showed two 5-foot intervals containing 0.99 and 0.39 percent
of lead, respectively.

Anomaly C

Anomaly C (figs. 13 and 14) is a circular, low-resistivity area with a north-
south axis about 415 feet long on section D-D' between test holes GB-72 and GB-76
and an east-west axis extending about 350 feet along section E-E' between test holes
GB-11 and GB-21, near the 10,000-ohm-cm, contour,

Shale slumpages in sinks are indicative of structural deformation and zones of

open and fractured limestone through which mineralizing solutions find free passage
and favorable conditions for deposition of zinc and lead minerals,

The proved practicability of using electrical-resistivity techniques to locate

slumped shale masses and accompanying structural conditions favorable for minerali-
zation eliminates unnecessary exploratory drilling in undisturbed areas and local-
izes drilling to areas or zones of low resistivity where the possibilities for
discovering zinc and lead ore bodies are most favorable.

HISTORY, PRODUCTION, AND MINING

The history of production of the Badger-Peacock camp has been traced back to
1900, although it is known that some zinc-lead ore was produced before that year,
By 1908 the records show production from the Spring River, Peacock Valley, and
Northcutt mines east of Spring River and from the Badger mine on the west bank of
the river, Production was considered heavy by Haworth in 1893 (2), By 1908 the
United Zinc Co, became the leading producer in the district,

Approximately 80 percent of the recorded zinc-lead production of the camp was
obtained from one 40-acre tract (NW1/4NW1/4 sec, 24) known as the "Peacock 40" (fig.
3). The production data for the mines in this tract for 1900-08 were obtained from
records of United Zinc Co, and for 1909-20 from statistics published by the Federal
Geological Survey and the Federal Bureau of Mines, Production from the tract during
the period 1944-46 was procured from records of Carson Mining & Milling Co.

Production statistics for the Connor land, now the Marie Myers land, which in-
cludes the Cincinnati and Colorado mines, are incomplete, Statistics on early pro-
duction by Badger Mining Co, from the mines in the Badger 40 area are also incom-
plete, Erasmis Haworth states in Special Report on Lead and Zinc (University of
Kansas Geological Survey, volume 8) that the company was a substantial producer as
early as 1898, Recorded production for 1907-19 is taken from statistics compiled by
the Federal Geological Survey and the Federal Bureau of Mines,

No record of output or of mining activities in the camp was found for 1921-43,
and there was no production since 1946,

Recorded production of zinc and lead from the Badger-Peacock camp is summarized
in table 2,

The major mine workings cover an area of about 17-1/2 acres, and nearly all are
connected, The main mining level is about 145 feet below the surface, near the top
of the Grand Falls chert (sheet-ground) horizon, Ore extending above the level was
mined close to the surface in some areas, now caved, as in the Thomas D, Spring
River, and Northcutt mines, The mine workings of the Federated, Arena, and Big Cave
mines, north of the St, Louis-San Francisco Railroad, as well as the Colorado mine
in the east part of the area, are in the sheet ground; no appreciable zinc-lead
mineralization was found above this horizon.

The 33-foot bed of Cherokee shale and sandstone in anomaly E is hard, well-
bedded, and dry and contains virtually no clay or selvage, The underlying Warsaw
and Keokuk limestones are tight, hard, and show no structural deformation, These
characteristics signify that the shale was deposited in normal sequence on the lime-
stone surface, where it remains as an uneroded remnant. In the Badger anomaly, the
Cherokee shale is extensively shattered and altered, and is intermixed with clay,
selvage, limestone, and chert boulders, indicating that the shale has slumped into
solution caverns in the limestone,

Structural deformation in the Badger anomaly extends into the Grand Falls chert,
and zinc-lead mineralization is evident in the limestone and chert below the shale,
Hole GB-93 showed traces of zinc and lead from 60 to 70 feet in Warsaw limestone and
from 135 to 145 feet in the Keokuk limestone, a 10-foot ore section averaging 1.66
percent zinc and 0,03 percent lead. Hole GB-95 showed traces of zinc and lead min-
erals from 35 to 55 feet in depth; from 95 to 110 feet, in Keokuk limestone, a 15-
foot ore section averaged 1,60 percent zinc and 0.01 percent lead,

These two shale deposits are dissimilar types, even though the anomalies show
the same range in resistivity, Anomaly E represents a shale outlier lying in normal
stratigraphic sequence and not entirely eroded, whereas the Badger anomaly represents
shale that has slumped into solution cavities in the underlying limestone, Without
the test drill holes, the anomalies might be interpreted as representing similar
structures,

Peacock Anomaly

The Peacock anomaly (figs. 19 and 20) lying east of Spring River covers an ex-
tensively-mined area from which most of the ore from the Badger-Peacock camp was
produced, Within or adjacent to this anomalous area are the Peacock, Northcutt,

S. H, & S,, Spring River, and Thomas D mines, A large part of the area is now caved
or covered with mine and mill dumps, which prevented more detailed investigation of
the anomaly,

The anomaly extends along a northwest-southeast section, J-J', about 1,600 feet
within the 10,000-ohm-cm, contour; a minimum resistivity contour of 2,500 ohm-cm,
lies in the central part of the anomaly, No test holes were drilled by the Bureau
of Mines; however, the majority of the holes drilled in this area by mining companies
showed isolated lenses of shale intermixed with fractured and altered limestone con-
taining crevices filled with highly mineralized water, The log of hole 81 showed a
shale thickness of 22 feet below 24 feet of residual deposits, The profile of the
top of the limestone on which the residual deposits and shale rest conforms generally
to the resistivity profile, The log of hole 9 near low-resistivity contour 2,500
ohm-cm, shows several ore sections, from the top of the limestone to the Grand Falls
horizon, aggregating 77 feet in thickness and averaging 2.01 percent zinc and 0,38
percent lead, The lower part of this ore body has been mined, Hole 81, near the
center of low-resistivity contour 5,000 ohm-cm,, shows a 10-foot ore section from 80
to 90 feet of depth averaging 2.01 percent zinc; and a 7-foot ore section from 135
to 142 feet, just above the Grand Falls horizon, averaging 2.01 percent zinc, Logs
of holes 47 and 51 near the northwest end of the anomaly show 2 ore sections near
the Grand Falls horizon 11 and 20 feet thick, respectively, both averaging 1.67
percent zinc,

The contours on the top of the Mississippian limestone (fig. 9) show that the
Peacock anomaly embraces three limestone depressions into which shale has slumped,
Evidently the shale slumpages are connected and may have formed one large, circular

The Federal Geological Survey, Geophysics Branch, with the assistance of Federal
Bureau of Mines personnel, made the geophysical surveys, consisting principally of
electrical-resistivity profiling and limited seismic refraction tests in selected
parts of the project area, The Bureau of Mines prepared the project site for the
investigations and did the test drilling,

Resistivity measurements, under the field supervision of Kenneth L, Cook, geo-

physicist, were taken at 50-foot intervals along east-west grid lines spaced 100 to
300 feet apart, the electrodes being spaced for an effective penetration depth of
100 feet, Approximately 13,236 resistivity observations were so taken along a com-
bined traverse length of 97.8 miles, within an area of about 3-1/2 square miles,
In addition, vertical depth profiles at 200- to 500-foot penetration were made on
89 traverses, The Geophysics Branch interpreted the resistivity data and prepared
resistivity contour maps and profiles for use in locating test drill holes and for
geologic correlation,

The Geophysics Branch, under the field supervision of W. E, Davis, geophysicist,
also made seismic refraction tests over four known sink structures, previously lo-
cated and defined by resistivity measurements and churn drilling, to determine if
shale slumpages into limestone sinks could be detected by refraction measurements,
The seismic profiles were run on 8 traverse lines for an aggregate length of about
16,600 feet.

The field crews for the geophysical surveys consisted of 10 men, 3 provided by
the Geophysics Branch and 7 by the Bureau of Mines,

The Bureau of Mines procured mineral agreements from the landowners; obtained
and assembled available drill-hole logs, mine maps, and other pertinent data on the
project site; made base land surveys and project maps; brushed and staked 97,8 miles
of grid lines; and churn-drilled under contract 96 test holes aggregating 17,628
feet of bore, The locations of holes drilled by the Bureau of Mines and by private
companies are shown in figures 3 and 4, Pertinent data on Bureau drill holes are
given in table 12; abridged logs of the holes are also presented in the Appendix,

GEOLOGICAL AND GEOPHYSICAL CORRELATION

Correlation of the resistivity data with the geology and structure disclosed
by Bureau of Mines drill holes reveals definite relationship between resistivity
anomalies and the character and structure of subsurface formations, Apparent resis-
tivity at 100-foot depth penetration ranges from a low of 2,500 ohm-cm, in anomalies
where drill holes penetrated thick deformed and altered masses of shale to a high of
67,500 ohm-cm, in an anomaly where hard, undisturbed limestone crops out, In all
anomalies tested by drilling, low-resistivity measurements indicate shale occupying
erosional depressions or filled sinks in the underlying limestone, and high-resis-
tivity measurements represent the absence of shale or highly fractured limestone at
or near the surface, The profiles of the shale-limestone contacts disclosed by
cross-sectional drilling generally conform in configuration with the resistivity
profiles,within the limit of depth penetration of the resistivity measurements,

The results of cross-sectional drilling of 22 anomalies to determine their
relationship to geological and structural conditions are shown on the accompanying
maps (figs, 8 to 38) and are described in detail as follows:

PRACTICAL EVALUATION OF ELECTRICAL-RESISTIVITY SURVEYS
AS A GUIDE TO ZINC-LEAD EXPLORATORY DRILLING,
BADGER-PEACOCK CAMP AND VICINITY,

CHEROKEE COUNTY, KANS.~”

L. G Brichte2/ and J. P. Ryon2/

SUMMARY

During a study of the Badger-Peacock area from October 1950 to June 1953, the
Federal Geological Survey and the Federal Bureau of Mines completed nearly 98 miles
of resistivity profiling and drilled 96 test holes aggregating 17,628 feet of bore.
In addition, seismic profile measurements were made along 8 traverse lines for an
aggregate length of about 16,600 feet.

The geophysical surveys were conducted by the Geophysics Branch of the Geologi-
cal Survey; the drilling was done by the Bureau of Mines,

Electrical-resistivity measurements disclosed 21 low-resistivity anomalies and
1 high-resistivity anomaly, Correlation of the resistivity data with the geological
information revealed by the drilling disclosed that the low-resistivity anomalies
indicated either slumped shale deposits in limestone sinks or undisturbed deposits
of shale lying in erosional depressions in the limestone, The high-resistivity anom-
aly indicated hard, undisturbed limestone at or near the surface,

The seismic surveys, which were confined to tests over previously defined shale
masses, proved adaptable for locating broad sink structures but were only moderately
successful in depicting the configuration and altitude of the underlying limestone
surface,

Although test drill holes were located to provide cross sections of the anom-
alies and not to explore for ore, several Bureau of Mines test holes, as well as
several holes drilled in previous years by private exploration, intersected zinc-
lead ore in some of the anomalous areas where structural disturbance and shale
slumpage have occurred,

The investigations revealed that electrical-resistivity techniques serve to
identify shale slumpages into solution cavities and channels along zones of struc-
tural deformation in limestone formation, By thus indicating subsurface structures
favorable to ore deposition, electrical-resistivity techniques can be utilized ad-
vantageously as guides for prospecting those parts of the district where geological
conditions are similar to those that prevail in the Badger-Peacock area,

reservoir favorable for ore deposition, The structural deformation is evident at
the Grand Falls horizon.

Drilling by United Zinc Co, (1906) in this area showed 28 holes in ore, on
which subsequent mining operations were based. Of 18 holes drilled in 1952 by
Minerva Mines, Inc,, in the same general area (fig. 3), 17 intersected traces of
zinc and lead and old mine workings; 1 hole penetrated a 42-1/2-foot ore section
from 27-1/2 feet to 70 feet, averaging 1.47 percent zinc and 0,20 percent lead;
evidently the hole was drilled in a pillar.

Anomaly N

Anomaly N (figs. 21 and 22) in the Cincinnati-mine area embraces two small
anomalous areas separated by a narrow strip of high resistivity, The smaller anom-
aly at the intersection of sections K-K' and L-L' has a northwest-southeast elonga-
tion, with a minimum resistivity contour of 12,500 ohm-cm. Holes GB-64, GB-65, 26,
and GB-58 define the east-west margins of the shale, and test hole GB-54 penetrated
a maximum shale thickness of 30 feet, below 20 feet of residual deposits.

The larger anomaly, northeast of the smaller one, is circular and shows a cen-
tral minimum resistivity area of 7,500 ohm-cm, Holes 34, M-12 and M-4 on section
L-L' define a shale deposit at least 450 feet wide; and hole 37 near the center of
the anomaly disclosed a maximum shale thickness of 95 feet in a low-resistivity area
of 7,500 ohm-cm,, below 15 feet of residual deposits, The shale is highly fractured,
altered, and intermixed with limestone and chert boulders and evidently has slumped
into a solution cavern in the limestone, The profiles of the shale-~limestone con-
tact conform with the resistivity profiles.

The log of hole 37 shows an 18-foot section of ore from 120 to 138 feet, with
an average grade of 1.34 percent zinc and 0.34 percent lead. The log of hole 70 on
the south flank of the smaller anomaly shows an 8-foot ore section in the Grand
Falls formation averaging 1.67 percent zinc, The log of hole 69 on the northeast
flank of the larger anomaly shows a 14-foot ore section in the Grand Falls forma-
tion averaging 1.67 percent zinc,

Anomalies H and J

Anomalies H and J (figs. 23 and 24), small circular areas about 600 feet apart
in the SW1/4 sec, 23, show a resistivity range of 12,500 to 7,500 ohm-cm, Anomaly
H, tested by drill holes GB-52, GB-35, and GB-51 on east-west section B-B', revealed
a shale deposit with a width of 250 feet within the 12,500-ohm-cm, contour and a
maximum thickness of 40 feet beneath 5 feet of residual deposits, The shale, as
well as the underlying limestone and chert, is intensely broken, altered, and cavern-
ous, Traces of sphalerite and galena are evident in the limestone, Anomaly J to
the west is the same type and character as anomaly H, Test holes GB-40 and GB-41
define the east-west margins of the shale on section B-B' corresponding to resistiv-
ity contour 12,500 ohm-cm,, a distance of 250 feet; and test hole GB-36, on minimum
resistivity contour 7,500 ohm-cm,, penetrated a maximum shale thickness of 40 feet
beneath 10 feet of residual deposits, Test holes GB-48, GB-43, and GB-49 on section
C-C' show that the thickness of shale diminishes as it approaches the south margin
of the sink, The shale, as well as the underlying formations, is highly deformed,
altered, and cavernous, Intense solution action evidently has caused collapse of
the formations in both anomalies, Hole GB-36 intersected a 21-foot ore section, 12
feet below the shale at a depth of 62-1/2 to 82-1/2 feet, averaging 2.02 percent
zinc and 0.07 percent lead, Hole GB-39, in the east flank of the sink, penetrated

origin, the ore deposits of the district are found only where structural deformation
created favorable pre-mineral reservoirs; the strate are barren elsewhere, The
sizes and shapes of the ore bodies are definitely related to the areas, relief, and
shattering of the structures that facilitated their deposition (4).

A stratigraphic section of the sedimentary formations in the Badger-Peacock
area, down to the Fern Glen limestone, is presented as table 1, The exposed surface
rocks are the Warsaw and Keokuk beds of the Boone formation and outliers of Cherokee
shale and sandstone that occupy depressions in the underlying limestone at elevation

below the present erosion surface, A large part of the area is covered with river
alluvium,

Most of the ore in the Badger-Peacock area was mined from irregular "circle"
deposits formed in and around sinkholes caused by solution action and subsequent
slumpage in the limestone beds, and from “sheet-ground" deposits in the Grand Falls
chert, The most productive horizon was the M bed, In some areas of extensive brec-
ciation zinc and lead mineralization has extended into beds above the M, almost
to the surface, Deposits in the Grand Falls chert (sheet ground) are nearly hori-
zontal, tabular ore bodies of greater lateral extent, developed parallel to the
bedding planes; they are limited to areas of brecciation and solution and generally
are of relatively low grade,

Frequent floods that inundated the mine workings on the Spring River flood
plain have seriously handicapped operation of the mines and discouraged new
development work,

During 1944-46 Carson Mining & Milling Co, erected a mill, reopened some of the
mine workings, and treated about 209,000 tons of zinc-bearing material from shafts,
open pit, and tailing piles on the Peacock 40. From these operations, 666 tons of
60-percent zinc concentrate was produced, Stripping near the Peacock mine disclosed
some shallow ore, but flood waters again inundated the mines and stopped all work,
No mining has been attempted since 1946,

EXPLORATORY CHURN DRILLING

The north part of the project area has been explored extensively by various
mining companies since 1901 (table 3), During the period 1901-10, United Zinc Co,
drilled 216 holes aggregating approximately 34,860 feet of bore, Of these, 72 holes
aggregating approximately 12,500 feet were drilled on the Colorado, Northcutt, and
Cincinnati mine areas in secs, 3 and 24, and 144 holes were drilled on the Peacock,
Riverside, S, H, & S, lease, Thomas D, Spring River, Columbus, and Federated mine
areas in secs, 13 and 14 (fig. 3). The complete logs of only 200 of these holes are
available, Pertinent data on these holes are summarized in tables 5 and 6 of this
report, The most profitable ore deposits discovered by the drilling were sinkhole
structures,

Cultivated lands cover approximately two-thirds of the area; the remainder is
heavily wooded and pasture land,

Many inactive mine shafts, mine dumps, and mill-tailing piles dot the flood-
plain area, where most of the mining has been done,

The annual precipitation is about 38 inches. Much of the flood plain is subject
to inundation during the periods of heavy rainfall, and mine workings have been
flooded on several occasions, The climate is moderate and permits year-round mining.
Temperatures normally range from 100° F, in the hottest part of the summer to near
0° in the coldest part of the winter, the extremes being of short duration,

Powerlines of the Empire District Electric Co, and a natural-gas line of the
City Service Co, cross the project area,

GEOLOGY AND ORE DEPOSITS

The geology of the Tri-State district, in which the Badger-Peacock area is
situated, has been described in publications of the Missouri Geological Survey Mal,
University of Kansas Geological Survey (2), Federal Geological Survey (3), and
others (4), (6), The general surface geology of the project area, adapted in part
from Geological Survey Joplin Folio 148 is shown in figure 7,

The Tri-State district lies on the western flank of the Ozard uplift and com-
prises an area of about 2,000 square miles in southwestern Missouri, southeastern
Kansas, and northeastern Oklahoma, Sedimentary strate of shale, sandstone, lime-
stone, chert, and dolomite of several geological systems overlie the granitic base-
ment rocks, Sedimentary thicknesses ranging from 1,045 to 1,815 feet have been
recorded in the few deep wells that have reached igneous rocks, For the most part
the sedimentary formations occupy relatively horizontal positions,

The Mississippian Boone formation and occasionally the overlying Chester forma-
tion are the host rocks of the ore deposits, The Pennsylvanian Cherokee formation
lies unconformably on the Chester and covers the greater part of the Oklahoma-Kansas
part of the district. In the Missouri part of the district the surface formation is
largely Boone, ranging in thickness from 100 to 300 feet;.the Chester and Cherokee
formations having been removed by erosion, For closer structural correlation Fowler
(4) has subdivided the Boone formation below the Chester to the top of the Fern Glen
into 16 distinct beds, lettered B to R (except I) in descending vertical order, In
many parts of the district, one to several lettered beds are missing at erosional
unconformities between formations, Beds M, K, and 0 have been the most productive,
although, in zones of intense fissuring, all beds from E to O are ore bearing.
Alteration by solution action has more or less silicified and dolomitized the strata
in the vicinity of the deposits.

Sphalerite and galena are the principal ore minerals; chert, limestone, jasper-
oid, and dolomite with minor quantities of calcite, and marcasite are the principal
gangue materials, A sticky calcareous md, locally termed selvage, is commonly
found filling crevices in the deposits.

The source of the mineralization has been ascribed variously to ascending hot
solutions, descending ground water, and artesian circulation, Regardless of the

4/7 Underlined numbers in parentheses refer to citations in the bibliography at the
end of this report.
