Pyramid Mining district is situate
about seven miles south OF Lordsburg
and embraces that portion OF Pyramid
range south Of Virginia Mining dis
trict. II takes its name from the
most prominent mountain i'm the
range. The principal mines in the
district are situate on the west foot.
hills OF Pyramid mountain. which has
an altitude Of nearly six thousand

The principal mines in the district
are the VENUS GROUP formerly
Niola). the LAST CHANCE, the MEL
LIE Bile GROUP and the ROBERT
T.. LEE mine. Around these mines
are a number OF prospects held by in
%iividuals. The veins Of the district
have a northeast southwest strike and
cut through tho comparatively level
uplands forming the western slope
from Pyramid mountain. Accompany
ing these main veins is a svstcm OF
cross veins which have a more east

The Venus Group Of Mines.
Situate in Pyramid district is one
of The oldest mines OF the district.
II was developed in the early eighties
and worked as a silver mine. the high
grade ore being shipped to the sme't-
crs and the low grade being millrd
in a fifty-ton chlorination mill on the
property. The minn was worked in.
tCrnittently until 1893 when the low
price OF silver together with the high
trNatWcnt cost caused the property to
b. closed. Up to this time the main

which cover about seven thousand
feet of vein.
The Last Chance Group Of Mines.
This group of mines join tho Venus
group on the south and west. and
cover the same system Of veins TO
Tho southwest. The main shaft OF
his group is $50 feet deep and has
several hundred feet Of cross-cuts
and drifts. This property has
hiprei over 100000 worth of silver
orc. There are two patented and two
rnpatented claims in the group. The
ores carry some copper values.
The Nellie Bile Group.
This group is located ON a system of
veins ono-half mile to the west OF tho
rain veins OF the groups Just de-
scrihed, and parallel TO them. Tho
ores Of this group have their prcdom-
mating values in copper and silver.

siderable drifting has been done and
about 100000 worth OF ore shipped.
