liably stated that the nicotite ore
streak was from two and half to
three feet in width, says he and
the whole vein carrys from &c to Is
ounces silver per ton, but the native
silver unusually occurs in a shoot
whose pay streak IS from eight to
twenty four inches wide and ASSAYS
from 400 to e.010 ounces silver per
ton.
Argentite (native silxerN sulphide)
occurs as Filing in fracture. and as
crystals on the ricotite and spar
gangue. Some hand specimens show
nicOtite. snialtite cobalt diarsenide)
millerite e. native nickel sulnhide,)
and crystals of native silver sulphide
with crusty masses of erythrite, (hy-
irous arsenate of cobalt.) and anna
bersite, (hydrous nickel arsenate)
Geology Alhambra- Black Hawk
! The sseology of the camp is simple.
The country rock is pre- -cambran
gneiss cut by. monozonite porphyry
bikes which radiate from the main
porphyry bikes on the northwest side
of Twin Peaks, according TO Leach.
The veins usually parallel the bikes or
are otherwise associated with them,
and are of the true fissure type, rang
ing from two to five feet in width.
They are all of the same general type,
having spar gangUe usually calcite
or barite, and invariably present in in
tensely breceiated appearance
During the period occupied by my
examination and survey in $780, says
| w. G. WarinS, of the Alhambra Mine
Il saw quantity OF ore stripped from
1 the apex of a single lenticular mass in
the floor of the third level, for about
40 feet southwardly from the North
/ Fault the stripping cutting only from
two to three feet into the ore, which
! estimated to be worth from $4,000 to
| $4,000 per ton. There can, therefore,
be no doubt that the Alhambra lode is
| of extreme permanence. Its, richness
cannot be doubted by anyone who ex-
amines the mine, it is really unique
and comparable with only one or two
mines ever known in the history os
silver mining. In fact the limited area
already explored can reasonably be
counted upon to yield ON the average
81. 600 per each foot in development
and probably very much more.
That it is capable, with judicicLs
and scientific development, OF produce
ing an amount of silver which can
only be measured by millions, | cal-
not doubt"
The development work on the Al
hambra consists of one two-com BART
ment shaft, 125 feet deep. one whim
shaft, so feet deep, one two-compart-
ment shaft 1865 feet deep. with levels
at intervals of so feet with wines at
intervals of IS feet from level to level

Width increases to feet between walls.

! Other Mines in Same District
In the same camp are other mines
which have been highly productive,
such ass the Rose mine. having two
veins developed by a 200 foot shaft,
with production $150,00G: The Hob
son mine with a 200-foot shaft, that
| produced argentite and native silver:
! Ine Good Hope mine, with 120-foot
! shaft from which native silver was
taken, etc. There is considerable ac-
tiNity in the camp at the present time
and some fthe newer prospects are
showing up so well they may be ex-
1 peeted to enter the producing class any
day. Some large chunks of very rich
native silver picked up few months
ago on east side of the camp nave slim
ulated prospecting somewhat and the
1 camp seems to be demonstrating its
ability to come back.
