ing. it becomes a great consumer of
nently, occasionally forming cliffs of
quartz from 20 to so feet high.
THE Albemarle mine, belonging to
the Cochiti Gold Mining Company, is
the best developed mine in the camp.
1t has reached depth of little less than
| 700 feet, and Is opened by seven levels
extending and opening the vein for 200
feet. The width of the vein above the
sixth level varies from 40 to IS feet. AL
| most the entire dixie material for about
800 feet longitudinally, and from the
third to the sixth level, is replaced with
quartz, averaging about 40 feet wide.
l am told by the manager at the mine
| that it will average $3.50 per ton. On
| the seventh level the vein has narrowed
| to from 10 to 20 feet between walls, and
it is said the ore has increased in rich
ness. The company has cyanide mill
erected at the mine with daily ca
pacity of 300 tons. 1t is constructed en-
! tirely of steel and iron, and was erected
by the Gillett-Herzog Manufacturing
Company of Minneapolis, MINI. The
sizes of the buildings are: Crushing
building, 16x1O0 feet; engine and boiler
room 4Ox62 feet; one teaching room, 68x
112 feet one 60x174 feet, and one 42x70
feet. The ore, when dumped into the
mill, passes over grizzlies, the fine stuff
being crushed in Huntingtons to fifty
mesh, and treated in Pelatin- Clerici
pans. There are three 6-foot Hunting
tons and eight Pelatin-C Clerici pans in
use. The crushing machinery consists
of two Blake 9x15-inch rock breakers,
four sets of rolls 16x36 inches, four
sets 12x20, furnished by the E. p. Allis
company, of Milwaukee, and two sets
16x36 inches, furnished by the F. M. Da-
Wis iron works, of Denver. The ore is
screened to "a mesh. In the teaching
rooms there are 12 round iron tanks, 25
feet diameter. with capacity Of 120 tons
each; eight rectangular tanks 25x30
feet, with capacity Of 200 tons each;
six round wooden tanks, 18 feet in di-
ameter, with capacity of seventy tons
EACH The depth Of each of the tanks is
61a feet. The saving Is reported to be
about 80 per cent of the total values.
'The mine is equipped with an cleo
trio plant, both mill and hosting works
being operated by electric motors. The
| dynamos are located at the Madrid coal
banks, thirty-one miles distant. The
plant does not work well, giving almost
| daily trouble; this Is the common re-
| port. Water power in ABUNDANCE is
found on the Rio Grande river, eleven
miles distant in a direct line, but after
investigating 1t Mr.. F. w. Hart the en-
gineer who erected the plant, decided to
use steam instead of water to furnish
the initial power.
1.-The Lone Star, at Bland, is the next
best developed mine in the district. 1t
is opened by adit levels for about 1000
feet, and to depth Of 800 feet below the
highest Outcrop. A crOsscut tunnel 1000
feet long has just been completed to the
vein. The mine has blocked out ap-
proximately 100000 tons of ore, having
an average value Of about So per ton.
This property has shipped about 100000
worth of ore carrying $40 per ton. The
vein varies in width from so to 100 feet.
"The Washington adjoins the Lone
Star on the south. 1t has been opened
by a shaft to a depth of 300 feet, and
has some hundreds of feet of levels. 1t
has shipped several car loads of ore
containing over $100 per ton, and has
considerable ore in sight, though not
blocked out, which samples from $40 to
$40 per ton. The mine belongs to an AL
buquerque company, and Is not worked.
1.-The Crown Point is situate about
one-half mile to the north of the Lone
Star, and is generally believed to be a
spur from the great vein. 1t Is opened
. by a shaft .approximating 300 feet. with
| several hundred feet of levels The vein
varies in width from 3 or 4 to 10 feet.
| The ore is found in pockets rather than
lenses. The values are mostly gold. 1t
has shipped probably $4,000 worth of
ore, and has considerable in sight
which samples from So to $40 per ton.
1.-The Iron King, adjoining the Lone
Star on the north. Is the first discovery
in the district. From a great cliff,
forming quarry where the discovery
was made, 1O2 tons of ore were shipped
which sampled $14.40 per ton. The mine
is developed by some hundreds of feet
of adit levels and shaft 100 feet deep,
| from which levels are now running.
"These are the only developed proper
ties in the district, though there are
many prospects having 100 feet or less
| development. Some of these show ore
samples from $S to 500 per ton In two
| of them the values are almost entirely
| gold, which amalgamates well.
"At Bland, the principal town of the
district, there is small mill with ten
stamps, two Pelatan-Clerici pans and
a couple of teaching tanks. 1t was
erected and run as a stamp mill some
years ago, with poor results, and has
passed through various process changes.
1t has lately been purchased by the
Navajo Mining Company, the owner of
the Lone Star, and has been used by it
as test mill to determine. the best
method of treating the ore. This COM
pany announces that it will this year
erect cyanide teaching MILL with a
daily capacity Of 300 tons, crushing wet
with stamps, using the Buffers Mein
distributors. following the South Afri-
can practice. 1t Is claimed that their
tests show a saving of 80 per cent.
1.-THE Cochiti Reduction and Improve
ment Company, operating the Iron
King, had mill at Woodbury., six
miles below Bland, until a few days
ago, when it was destroyed by fire. 1t
was pan amalgamation mill, devel-
oped from process plant erected on
the ground in 1894. which proved fail
ure. 1t fell to my lot to work out a
plan for utilizing it, which I did by
plant that, so far as l know, has not
been used elsewhere. Treating the ore
by raw amalgamation 1 was able to
save upward of 20 per cent, treating it
| after roasting the saving was consid-
| erably better. The plan developed was
to crush to thirty mesh in rolls, pulver-
ize in Alsing continuous feed and dis
| charge cylinders to 100 mesh, when 1t
was charged into ordinary 5-foot COM
bination pans. The charge was two
tons to the pan. Twelve pounds of So
dium chloride were added to the charge,
steam turned in and the charge run
thick. Caustic soda was added until the
reaction was alkaline, when $50 pounds
of quicksilver were added. In a few
minutes pounds Of potassium cyanide
were added and an electric current
turned on. A low amperage dynamo
was used, iron forming the anode and
the quicksilver the cathode. All ores
were sampled when crushed through
the ordinary pipe sampler and samples
were taken from the settler discharge
every fifteen minutes. The water was
decanted from the sample and evapo-
rated to dryness, the residues assayed,
twelve half-ton samples being taken for
assay. The samples, after decantation,
were also assayed; and from other
samples the entire water was evaporat-
ed without decantation. This was for
the purpose Of locating the losses, and
they were found to be almost entirely
in the pulp instead of in solution. The
