contain good ore: on the west the
same condition seems to exist, Out
here only the north wing Is minaoie,

abruptly in this direction. The cause
of this narrowing. locally referred 10
AS n break, is not very obvious. The
h, eak does not coincide with any clean
cut fault, separating good ores from
barren country rock but Is merely
rather abrupt change from CONNER
cial ore to poor ore. Close examina-
ton shows, however. that such breaks
coincide approximately with assures
striking about North 30 degrees-'
degrees west. The broad Part OF the
ore body was therefore probably FORM
ed by replacement of the prism OF
shattered rock produced by the IN
| tersection of two zones OF hssurihs.
The outlines of the slopes Suggest
that there was some slight dispiace-
ment of the veins on the cross MS
sures. but its effect is blurred by SUD
seauent naturalization and by the lack
of definition In the ore body. The vein
! is not seriously displaced by cross
faults in any part of the mine me
northeast ore body opened by the
north Slope, shows similar pranch-
ing into wings. The north and Ryan
crosscut stope are connected on the
higher levels.
The most southeasterly ore pody
was worked in the iron stope probably
SO called because Of the large proper
ton of pyrite it contained. This pody
vas not over 10 feet wide In the ac-
cessible workings and tapered out
short distance below the No tunnel
level. The principal ore body OF the
south vein is in the south central part
of the workings. It Is developed IN
the bench Slope, which extends upward
from the adit level into the old aban-
doned levels, and the so-called south
stone that extends 200 feet below the
j adit level is evidently In a downward
continuation of the same shoot Inc

in what appears to be the same rela-
lively small ore body.
Although ore has been found on the
lowest levels yet attained, little ex-
ploration has been done on these and
the quantity of ore available below the
adit tunnel is unknown.
Character Of Ore.-The chief valua-
bic constituent of the Hunter ore Is
galena and the gangue is chiefly sid
erite Quartz and barite are other
abundant gangue minerals, barite be-
/, ing more abundant than In any other
producing mine Of the region. Metal
lie sulphides of minor economic i'm
. portance, though occurring in consid-
cradle quantity, are sphalerite ana
pyrite. Pyrite is rather more abund-
ant than in most other mines of the
district and seems to be particularly
so in the margins and ends of ore bod
les. Sphalerite is certainly less abund-
ant than in the Morning mine and has
shown no very notable increases with
depth Stibnite Is widely though ur1-
evenly and sparsely distributed and is
invariably inclosed in quartz. Tetra-
hedrite, which has been an important
constituent of the ore in the mine as a
whole, is said to occur in, the lower
levels.
, Conspicuous banding roughly paral-
lei to the walls Is rather more charac-
terstic of this lode than of others In
the Occur d'Alenes. The bands, few
of which individually are more than A
foot thick are distinguished by pre-
, vaence of siderite. quartz, country
rock or barlte as the matrix Of the ore
minerals, and also by the varying
abundance of the ores. The best ore
now being mined is a streak of, barte
and galena along the north side of tho
vein. For the width of foot or two
in many places these two minerals al

admixture.
