RICH COPPER FIELD.
Las Vegas Has Bright Prospects as
a Mining Town.
ON ALL SIDES.

Las Vegas now thinks of little else
but copper and the development of the
copper field which il is believed is
around the town. The field has been
developed in recent years. The dis
coveries in the Salitre district by A.
l.. Quinley'and Mr.. Baker caused II. f.
Blake to go the San Pedro district,
eight miles northwest. in January,
1901. Up to lnat time that district was
unknown. II has since been developed
n worked by many and one of the
most active is w. b. T~witchell who
is at the head of a large company.
The development of the copper fields
much to Las Vegas and the bus
mess men there are putting forth
every effort to secure reduction plants
and to induce capital to go in there.
Many of the business men of the city
own claims in the different mining
districts and Mr.. Twitchell went to
Denver to order the machinery for the
new extraction works which will be
placed on his company's property. It
will be the first mill put up in the Tee
olote district.
SAN PABLO DISTRICT.
The San Pablo district lies in the
foothills to the east of the main divide
DttNtGh inc ICCOo. III hdlllndS llNtlS.
1t lies some fifteen miles in an almost
due westerly course from Las Vegas,
within ten miles of the line of the At
Gibson, Topeka G. Santa Fe railroad,
and is more thoroughly defined by TAX
ing the course of the Tecolote river as
the eastern boundary commencing
above the village of San Geronimo:
thence running southerly along that
stream about four miles to the Tee
olote district; thence west six miles,
to the top of the divide of the main
range; thence n%ortherly to a point
west of San Geronimo: thence east to
the town.
OVERFLOW GROUP.
The Overflow group comprises forty
acres and 1t was here the first dis
covery IA made. In August of 1901,
systematic development commenced
and now there has been completed
a shaft fifty feet deep. with a drift
from the twenty foot level of forty
feet.
The rock is composed of a conglom-
crate of the Archaean sandstones car
rying values in carbonates of copper
together with gold and silver. It lies
in the form of a blanket or overflow
and has an exposed surface showing
mineral for a distance of 500 feet in
length, being uncovered on top a dis
lance of 200 feet toward the hill, be-
fore dipping.
The shaft was commenced at the
lodges intersection with the hill, and
cut through it at a depth of thirty
seven feet. The whole body shows
values of copper the entire distance,
with scarcely a barren streak, al
though not entirely uniform.
The drift, at the twenty foot level
runs under the hill a distance of forty
feet n shows the body to run under
cover with slightly increased values,
thus putting In sight a body of ore
5C0x240x37 feet. or 166. 292 cubic yards.
Counting two ton to the. yard. This
gives in round numbers 1872, 1892 tons of
ore actually in sight on the property.
Assays on this body vary from 3h to
10 per cent copper, and run as high as
1884 gold, and five ounces in silver.
Careful estimates give the average of
copper at u per cent, which under the
present cheap facilities for teaching
this class of ores, gives perfect assur-
ance OF an unlimited body of pay dirt,
with milling facilities on the ground.
THE SANTA RITA.
From the same plant can be worked
the Santa Rita group, which was open
ed up in November, 1901, by Donicio
Martinez. and lies about 1900 feet
south of the Overflow.
The mine has been opened in two
places, some twenty feet apart, the
ledge showing to be about ten feet
In thickness, with a pay streak of five
feet. Sample runs from the pay streak
give an average of ten per cent copper
with good values of gold and ASSAYS
unnlng as high as IA per cent copper
and silver. There are approximately
four carloads of ore on the dump. with
probably 1000 more tons in sight. AL.
though the development is scarcely
begun here, the tunnel just commenc-
Ing under cover, the vein shows evid-
ence Of being a very strong one, there
not being a thin streak in the lower
five feet of ledge matter. The upper
stratum of ledge matter has not been
tested, but values are distinctly visible
to the naked eye and it is not improba-
Bile that this also can eventually be
worked at a profit.
Both of these properties are at pres.
ent under bond and lease to w. b.
Twitchell.
THE GONZALES GROUP.
Three claims two miles southwest
from San Pablo and at the base of the
main range. form the Gonzales group.
BY quarry method a great deal of low
grade ore can be extracted, but it will
eventually be a deep mining PROPOSE
ton. Sulphurettes of copper are seer
IN an opening on this ledge about $500
feet north.
The group is being developed by
Messrs. Blake, Blauyelt and Ham.
mond, the pioneers of the amp The
ore body is in the form of a dyke trav-
ersing the country in a northwesterly
to southeasterly course, and lies be-
tween the lower or Dolmite lines and
the sandstones. The principle opening
consists of a siXty-foot cut and a tun-
ne which cuts the main vein at a
depth of fifteen feet. This opening
shows an ore body ten feet wide stand
ing almost perpendicular, and carrying
an average value of 8 per cent copper
with traces of gold and silver. There
