Uncle Sam Adit Driven Farther
At the mines about $40 feet will
be adedd to the length Of the Uncle
Sam adit before It will reach the Fri
day" shaft In the Hamburg ground.
About 100 feet has been driven since
the adit passed the dividing line be-
tween the Uncle Sam and the Ham
burg ground. While the adit will
open ground to a depth OF only 500
feet below the surface, the Hamburg
mine has been partly exploited to q
depth of $50 feet, without much stop
ing of the ore encountered. About
10000 linear feet of workings show
the extent of exploitation In Ham
bur ground. Less than one-nfth of
that has been performed on the bot
tom lode. while between the $50 and
$50 foot levels are extensive work.
ings from which no ore has ever been
removed to the knowledge of the
present operators. From above the
450-foot level all the richer ore
known to the Hamburg Company was
removed. but there are large reserves
Of low grade material remaining. and
1t is expected that all OF its assaying
over 81 ton will net a profit in the
milling. While tho resources of ore
available in the bosh mines may sur
pass $4,000 tons, vhat part of the
bulk may be Of higher low grade can
be ascertained only BY mining and
sampling it.
Many Mines ON This Lode
The Uncle Sam and Hamburg mines
are situated on the one lode. on
which are also several other produc-
ing mines. including the California
and Silver King, Connolly, Home
Ticket and Dunderberg, owned by
the Eureka-Croesus Company, the
Sentinel, Clipper, Blue Bird and Col
den Rule, owned by the Golden Rule
Consolidated Mining Company Of Ne
vada, the Helena Mortimer and 9TH
ers. The same break, ON which all
these mines are situated extends from
the south end of Ruby Hill, on the
north, ten or twelve miles southerly,
to and beyond the "sfindfell, the old
and rich," Page & Corwin and other
mines. the Fish Creek Valley. On
this same break of ground the Eu-
reka Croesus Company recently
struck a valuable body of ore in a
winze sunk on a plane of about thir-
ty degrees from the bottom of the
"Catlin" shaft, at vertical depth of
400 feet, and said to be terminating
at distance northerly of 500 feet
(equal to a horizontal distance of
about ATS feet), at or very near to
the south end line of the Sentinel
mine and at an approximate depth of
SIS feet lower than the collar of the
"Catlin" shaft.
Five Separate Ore Shoots
The Uncle Sam Consolidated Min
ing Company has encountered In the
Uncle Sam ground five separate
shoots of ore, In which there is prob
ably more or less high grade mater
ial, aud three Of them are under de-
velopment for expected profit. Sew
eral small shoots or stringers OF ore
were cut In the Uncle Sam adit, in
which high grade was present in
small proportion. The high grade
will be separated from the bulk and
shipped to Salt Lake, and the low
grade will be held for milling at
home. The last $50 feet of the adit
is now In Hamburg ground and again
entering an ore zone.
1t Is expected that access to the old
Hamburg mine workings will be made
through the Uncle Sam adit by about
May 30, In the east drift, OF from
the adit. Ave separate shoots of ore
have been encountered, which may
yield considerable tonnage. The Un-
Gle Sam high grade is being sacked
for shipment as soon as wagon haul
age down New York canyon becomes
available,
The adit has cut into fault which
is believed to have thrown the ore
bearing strata northward from the
Hamburg to the Uncle Sam ground.
Within the next 100 feet the adit will
come under point where the Ham
burg main ore body was developed
down to the 500 foot level and the
ore was of good value, From that
point a survey will be made to con-
meet the adit with drift from the
Friday" shaft on the 400 foot level
In the Hamburg ground. This sec
ton is all virgin ground below the
500 foot level.
