ALASKA MINERAL DISTRICT.

series of lodges on Barandoff Island,
about FIVE to fifteen miles from Sitka,
The formation OF the district is pyrite
and the casing of the lodges Is OF
manganese slate. The ores are au-
riferous quartz, carrying but little
free gold, but auriferous pyrites
and arsenical sulphurets of iron, with
now and then few pyrites o. copper
and galena. The ores are low grade
from $s to SIS per ton, as tried and
proven by the workings of little
ten-stamp mill erected by the Alaska
Gold and Silver Mining Company of
Portland, Or, which Company owns
the Stuart mine, the most developed
claim in the district, showing up .
ledge from four to thirty feet solid
ore, the whole length of 5000 feet
THE length of the Company's prop
erty). A number of other just as
good lodges are in the district, and
SO far as prospected. show up to be
good veins OF pay ores, if sufficient
copital could be raised to further
develop the mines. l have myself
expended considerable capital in
prospecting these lodges, and am
satisfied that with the proper working
of these mines good profits could be
i arrived at. The cost of extraction
would not exceed 81 SO per ton. az
all the mines can easily be worked
by tunnels for number of years to
/ come. The cost of milling in a
mill of twenty to forty stamps
would not exceed 81 SO per ton
The expense of milling in the little
ten-stamp mill now there costs 50 2;
per ton.
| The. mines are easily accessible
some coming clear to deep-wate'
edge, and none are over three miles
from shore. There is plenty ofwooc
and water around all Of them. Th'

On the north end of Baranot

Straits, party of mining prospec

; geological formation of the quart
lodges are four tissure veins of auri
erous quartz, carrying galena ant
selenite of lead and arsenical sulphu
rets of iron. The mineral belt

width, bearing north eighty degree
west by south eighty degrees cas-
the ssme course as the ledges,
which there are apparently eigt
main lodges and a number of smalle
parraIell veins, from ten to thre
hundred feet apart. On most of th
main lodges there have been mad
from ten to twelve locations, each
800 linear feet in length. The torn
alton OF the mineral belt is q met
morphic slate, the lodges being mos
ly incased in manganese slate, whic
forms the gauches of the ore bodie
and carries considerable amount I
the precious metal. The north wa
n of this mineral belt is primiti'
a granite, forming the summit of Il
vast mountain range, with an altitut
of 4 900 to 5000 feet. This part
unexplored. The south wall OF Il
mineral belt is synitic gneiss, inte
mixed with basal.ic states, AT q
contact of the south wall and miner
belt runs large lode offelsite Of To-
, grade ore, which is apparently t
mother belt. The quarts locatio
