table. was mounted on the back of the drill frame. to drive an auger bucket
through an extension shaft and counter shafts. Buckets used were 20 inches in
diameter and 18 to 24 inches long (fig. 6). A trapdoor auger bucket was first
used, but it would not cut through the hard quartz clusters found in the ore.
An open-bottom sawtooth bucket with the cutting edges of its teeth reinforced
with hard metal was substituted, and better results were obtained. The bucket
samples of the unconsolidated material were satisfactory, but the bucket bits
would not cut through the ledges-of hard rock.’ When one of these ledges was
encountered, a 20-inch Mother’ Hibbard bit (fig. 7) was used, together with the
churn‘ mechanism rather than the rotary. Once through the ledge, which might
"be several inchesor several feet in thickness, rotary drilling was resumed
with the bucket bit. ‘Thirtoen holes ranging in depth from 15 to 61 feet were
drilled with this rig... The average depth of bucket-drill holes was- 41 feet,
and tho total depth was 531.5 feet. The drill cut a core 20 inches in
diameter, which averaged about’270-pounds in weight for each foot of depth of
material, and the ore was ‘preserved in its original character, except when it
was necessary to use the Mother Hubbard bit. Cores were combined for. inter-
vals, usually 5 feet, and coned and quartered to obtain a sample that would
weigh 50 to 60 pounds. Composites were made up from these samples for
netollurgical testing. ,

Although samplbs obtained by the diamond drill were not suitable for
metallurgical tests,’ the holes drtiled by bucket drilling provided an’ excellent
metallurgical sample. Seven holes were diamond-drilled for the purpose of
determining the grade and extent of the ore body below: the depth to which it
was possible to drill with the bucket drill. In addition, two ‘of the bucket-
@rill holes were deeperied by the diamond drill. As work progréssed on the
project, more efficient techniques were developed for the diamond: drill, and
core recovery was improved. It was found that the best recovery was obtained
by cutting the water pressure on the drill to the minirmm required to keep
the bit clear of cuttings while mintaining a cmstant bit pressure and a low
speed of rotation. A low rotating speed was essential for the reason that
when the rotating speed was increased, it was necessary to increase the
pressure and volune of the woter to avoid burning the bits, causing o higher
loss of core by washing. A high rotating speed also caused a high loss of
diamonds from the bits when a quartz cluster was encountered.

Near the end of the job, a Baker cable tool core barrel (fig. 8) was
adapted to the bucket rig by utilizing the churn-drill mechanism with which
it was equipped. One hole 82 fect deep was drilled with the Boker tool with
very sotisfactory results. It was found possible to drill to greater depth
‘than with the bucket drill and to obtain’ 85 to 100 percent core recovery.

The core obtained was 2-11/16 inches in ‘diameter’ and large enough to be suit-
able for netallurgical testing.

The Baker cable-tool core barrel (fig. 8) consists of two main parts -
an outer. drilling barrel and.on inner. corerretaining.tube., The: drill. barrel
is composed.of three parts - the. drill barrel head, ‘the min drill barrel,
and a drill shoe or bit. Tho driil barrel head, which is. screwod .to the sten,
contains a valve that opens’ on’ the upstroke ;. water rushes in. through holes on
the side; and on the downstroke the valve closes,’ forcing the water to the
bottom of the hole, where the cutting is going on. The outer drill barrel is
a seamless steel cylinder 8-1/2 feet long. The bits or drill shoes are 12

WORK DONE BY THE BUREAU OF MINES

The first-problan that confronted the Bureau was the choice of a drill
that would be capable of (1) recovoring representative samples of the ore that
could be used in metallurgical research. This problem has been ably discussed
by Dupuy. 2/ It was essential that the samples be so taken that the natural
characteristics of the ore ranain wmaltored as these characteristics are deter-
mining factors. in devising beneficiation processes. (2) The drills also should
be capable of penetrating layers of sandy clay, clay, and hard rock and (3)
penetrating to depths of at lesst 150 feet. Work previously done by the Bureau
in the Magnet Cove a: O/ showed that a chum drill, although capable of
meeting requirements (2) and (3), could not fulfill the first requirement. In

the churn-drill sludges, the physical character of the ore minerals had been
altered,

Preparatory work started in December 1947, but drilling was delayed by
pad weather and did not start until January 12, 1948. A diamond drill (fig. 4)
and a series M-type, double-tube core barrel were used. In this core barrel,
which was designed to improve core recovery in soft or broken ground, the core
lifter or retaining spring operates inside.o core shell attached to the inner
barrel. The inner barrel is suspended on ball bearings and is free from the
rotation of the outer barrel, which carries the cutting bit. It. extends down
close to the face of the bit. Thus, the core passes into the nonrotating
inner barrel immediately above the cutting face of the bit and the tendency of
the core to grind upon itself or block the barrel is greatly reduced. Also,
the area in which the circulating drill water comes in contact with the core
is mech smoller than that ofa standard core barrel, and washing away of core
minimized,

The first attempts to procure a core were not altogether successful. Core
recoveries ranged as high as 60 percent. Sludge samples were recovered by
advancing the casing to the bottom of the hole after cach run, but, as in the
case of the churn-drill sludges, they were not suitable for metallurgical
testing.

In the latter part of January a combined foundation exploration rig or
bucket drill mounted on a four-wheel drive ‘truck wos procured (fig. 5). The.
rig provided for both rotary and churn drilling. It was equipped with a
spudding beam, 32-foot collapsible steél derrick with shock-absorbing crown
pulley, a 7-ton double-drum hoist, smo1l single-drum hoist, and string of
regular churn-drilling tools as well as a rotary table, kelly, and drilling
, buckets. Power was supplied by an auxiliary gasoline motor. The 30-inch rotary

DESCRIPTION OF THE DEPOSIT

Most of the Christy deposit ig in the $1/2, SW1/4, SWI/4, sec. 16, T. 3
8., R. 17 W., Hot Spring County, Ark. A portion of the deposit extends south-
word into the Nwi/4 of the NW1/4, sec. 21, T. 3°S., Rs 17 W., which, property
is a portion of the J. H. Rutherford Estate 9 Ce a. Rutherford, administrator,
Malvern, Ark.

The only mine workings on the property are the adit driven in 1913 by
the Titanium Alloy Manufacturing Co. and 34 test pits dug by Christy in 19he.

The adit. runs in 2 southeasterly direction from Chamberlain Creek gorge,
which is on the western end of the deposit. Tho adit has long since caved
and become inacessible. Its length is not mown, but old residents who “worked
in it have reported thot it progressively penetrated 75 to 100 feet of “barren,
ground, 40 fect of titanium-bearing moterial, another 4O feet of barren ground,
then ore to the face. Christy cleaned out and opened the adit for a length of
90 feet in 1942. He states that the end of the adit was in ore when he stopped
work, but the ground was badly caved and the ore was not in place. No sample
records are available.

Folbrook 7. gives the following generalized geologic section of the Paleozoic
formations in the Magnet Cove area, where the Christy deposit occurs:

According to Holbrook; "The regional structure is a group of tightly folded
Paleozoic sediments intruded by the Cretaceous igneous rocks of Magnet Cove. A
series of parallel anticlines and synclines trend roughly northeast- “southwest
and plunge to the southwest (fig. 2)3 locally, the Magnet Cove antrugives_
truncated one of these plunging anticlings. This truncated anticline is ove
turned to the north, and ore deposition.has taken place in the north limb.

INTRODUCTION AND SUMMARY

During the first 6 months of 1948 the Bureau of Mines investigated the titania
deposit on the Wynn 0. Christy property in northern Hot Spring County, Ark.
The property is situated in Magnet Cove, about half a mile north of the Magnet
Store and U. S. Highway 270 (fig. 1). The purpose of the investigation was to
determine the extent and grade of the ore body and to obtain a representative
sample of the ore in as nearly natural condition as possible for use in metal-
lurgical testing.

All of the titania that has been marketed from Arkansas mines has been. in
the form of rutile from a deposit about 2 miles west of the Christy property.
The titania in the Christy property occurs principally as brookite, which,
with fragments of novaculite, quartz, and limonite, is imbedded in red clay.
It is difficult to recover a core of the material. Three types of drills - a
diamond drill, a bucket drill, and a Baker cable-coring tool operated on a
churn rig - where employed in an effort to procure proper samples in their
natural state. The Baker tool was found to be the most efficient and to be
capable of drilling to a depth of 150 feet, making 80 to 100 pertent core
recovery (fig. 8).

Total footage drilled was 1,536.9 in 21 holes, of which 7 were diamond-
drill holes, 13 were bucket drill holes, and one was drilled with the Baker
tool. The ore body was found to be 900 feet long, 500 feet wide, and more
than 141 feet deep and contained 5.8 percent Tid, and 0,52 percent V50 « Most
of the deeper drill holes bottomed in ore, and there is a possibility that the
ore may persist to a depth of several hundred feet.

The Metallurgical Division of the Bureau of Mines is conducting experi-
mental work at the Mississippi Valley Experiment Station at Rolla, Mo., for
the purpose of developing methods of concentrating and utilizing the ore.

ACKNOWLEDGMENTS

Field work was under the general supervision of Leon W. Dupuy, chief of
the Rolla Branch, Mining Division, and under the immediate supervision, first
of A. B. Needham and later of the author. Sample analyses were made, and
beneficiation tests are now being mde by the Rolla Branch, Metallurgical
Division, R. G. Knickerbocker, chief. Samples were analyzed first at the
Bureau pilot plant at Bauxite, Ark., W. A. Calhoun, metallurgist in charge,
and tho analyses were verified.at the Rolla Laboratory. The metallurgical
research was conducted by M. M. Fine at Rolla.

Through the cooperation of Harold B. Foxhall, Director, Division of Geology,
Arkansas Resources and Development Commission, geologic maps of the area pre-
pared by Verne C. Fryklund, Jr., were made available to the Bureau, and all drill
cores were logged by Drew F. Holbrook.

LOCATION AND ACCESSIBILITY
The Christy deposit is in the $1/2, Swi/+, Swi/4, sec. 16, T. 3 S., Re
17 W., in northern Hot Spring County, Ark. It is situated about half a mile
north of the village of Magnet, which is 8 miles north of Malvern and 14 miles

east of Hot Springs on the.Malvern-Hot Springs highway U. 5.270. A graded
gravel-surfaced road crosses the property. It is found at 340 27! 20" NL
lat., 92° 50! 45" W, long.

Two railroads, the Missouri Pacific and the Chicago, Rock Island & Pacific,
pass through both Malvern and Hot Springs, the line of the latter about 4 miles
south of the property.

An electric power line crosses the property, and a natural gas pipe line
passes nearby.

PHYSICAL FEATURES AND CLIMATE

Magnet Cove, in which the Christy deposit is situated, is a small valley
or basin enclosed by rather sharp ridges. The highest and sharpest ridges are
on the north and west sides of the cove. The longer axis of the-valley is from
northwest to southeast. The altitude of the floor of the valley is 400 to 500
feet. The surrounding ridges rise to altitudes of 900 feet on the north and
west and 600 on the south and east. Cove Creek and Chamberlain. Creek flow from
the northesst. They join in the northeast part of the valley and cut through
the enveloping ridge on the south to flow into the Ouachita River, which flows
east to a point, south of the cove where it turns to the south. The Christy
property is situcted on the brow of a small hill on the east side of the cove
at on altitude of 600 feet, Chamberlain Creck runs southwesterly along the
western end of it through a smll but deep gorge. Except where the land has
been cleared for farming or mining, the area is thickly timbered with second-
growth pine, oak, hickory, and gum trees.

Average onnual rainfall in the area is 47 inches. The mean average
temperature is 61 degrees,

HISTORY

The first report of the occurrence of rutile and brookite ‘in the Magnet
Cove area was mde by J. F. Williams 2/ in 1890. Additional geolggdcal studies
were made by Henry S. Washington3/ in 1900 and Kenneth K. Londes +/ in 1931.

The first-lnowm attempt to explore the Christy deposit was made in 1913
by H. E. Perkins, acting for the Titanium Alloy Manufacturing Cos, which held
a@ lease on the property. The work consisted principally of driving an adit
from Chamberlain Creek gorge on the west end of the property.

After the work supervised by Perkins stopped, the property passed through
the hands of several parties and eventually was ‘owned by Jolm Inglis, who
willed the property to his son, Foster Inglis.

inches long and have 10 teeth faced with stellite. Watercourses are provided
on the inside of the bit, permitting water to circulate between the drill
barrel and the inner core tube.

The core tube’ also consists of three parts - the core tube head, the
main core tube, and the trimmer shoe. The 13~-1/2-inch tube head is expanded
on the upper end to forms shoulder, which prevents it from falling through
the bit. The core tube head is equipped with a ball check vaive, which allows
the water to escape while the coré tube is filling with core; 1t also prevents
direct water pressure on the core in the tubé. The core tube ,is 7-1/2 feet
long and is screwed to the head. The trimmer shoe screws on to the bottom of
the core tube, is 3-1/2 inches long, slightly beveled on the bottom, and faced
with stellite. On the inside of the shoe is a tapered trap ring, which retains
the core,

Tn operation, the inner core tube does not lift off. of ‘the bottom of the
hole. The outer drill barrel slides up and dow over the, inner tube, cutting
a core 3-1/2 inches-in diameter (fig. 9). -This, in turn, is cut by the
trimmer shoe to 2-11/16 inches in diameter. The core is pushed up into the
inner core tube and held thre by the tapered trap ring. Best results were
obtained by running with a slower motion than is used in regular churn drilling.
A speed of 25 to 32 strokes a minute was found to be about right. It was ‘
essential to run with a fairly "tight" line and keep the tools hitting evenly
at all times to avoid a crooked hole»

The core was split, and half of it was retained for reference. The other
half was split again, and one quarter was made up into samples for chemical
analysis, and the other quarter also was made up into samples and placed in
airtight cans for later use in making up the composite for ‘metallurgical
testing. Samples were analyzed for TiO) and Vj05, and weighted averages were
calculated for each hole. Samples were prepared’for analysis at the Bureau
pilot-plant laboratory at Bauxite, Ark., under the direction of W. A. Calhoun,
Analyses and check runs were mde at both Bauxite and the Mississippi Valley
Experiment Station at Rolla, Mo., under the supervision of R.’G. Knickerbocker.

A composite sample from 11 of the bucket-drill holes gave the following

A total of 1,536.9 feet was drilled in 21 holes. This includes footage
in holes C-2, C-3, C-l, and BD-12, which were lost and had to be re=drilled.
Altogether, 1,488.9 feet of hole was sampled. The area covered by the drilling
was 900 feet long and 500 feet wide, The greatest depth attained by any of the
drills was 141 feet in hole BD-4-D.

a loosely consolidated, red, clayey material, with fragments of porous clusters
of quartz crystals and coarse-grained’ métamorphosed novaculite. Dark-red clays
compose the major portion of the deposit from the surface to a depth of about
10 feet. Below that depth, lenses of. a very fine white to blue-white clay are
encountered. ‘These lenses vary in thickness from several inches up to 3 feet,
and their orientation does not seem to correspond to the surrounding structural
trends.

CHARACTER OF ORE

Holbrook */ states that the titania is found principally as subhedral
brookite crystals in the porous, metamorphosed novaculite, in quartz veins,
and disseminated with the crystal fragments in clay, with individual .brookite
crystals ronging from several millimeters to over a céntimeter in length. The
presence of pseudobrookite, minute needles of rutile, and leucoxene in the
quartz grains has been noted. Limonite and hematite are found as a cementing
agent in the porous novaculite and clay. .

In April 1945, 20 check samples were taken from nine of the test pits by
T. M. Romslo, an engineer of the Bureau of Mines. At the time this sampling
was done, it was impossible, because of water and caving of the walls, to
sample to the original bottom of the pits. Results are given in table l.

The test pits were again sampled in January 1947 by engineers®/ of ‘the
Bureau of Mines. Channel samples totaling 2,900 pounds were taken from 21 pits.

The average weight of the unconsolidated mterial in place was estimated
to be 111 pounds per cubic foot, or 18 cubic feet per ton, .The ore in the
lower portions of the ore body my be somewhat, heavier, ‘as it contains more
rock and clay.

METALLURGICAL ‘TESTS

Numerous samples from the Christy deposit have been subjected to metal-
lurgical tests by various organizations, including the “Bureau of Mines. Samples
tested in the past were from shallow surface diggings » principally test pits.
The best concentration of brookite was reported for samples that probably were
from the surface of the openings, where rain, had-washed away some of the clay.
The samples taken by the Buroau. tad not “been subjected to washing by rain and
therefore contained material’ amounts of clay. Bureou laboratories found it
difficult to duplicate tests previously reported. Beneficiation research is
currently under way at the Rolla, Moe, laboratory of the Bureau of Mines. The
research has not progressed sufficicntly for a report at this time and therefore
