conrad's Crossing.
In the vicinity of Conrad's Crossing
on ST. Joe river few short adits an6
trenches have been made on small
veins that are numerous in the dia-
base. The country rock is severely
sheared and more or less miperalizeG
in many places. The naturalization
consists in the introduction Of minute
crystals of chalcopyrite and pyrite
along shear planes and the Develop
ment Of seams and irregular punches
up to 3 feet or more wide Of calcite,
quartz and siderite carrying chalco-
pyrite and pyrite. The green stain cG
copper carbonate may be seen at many
places on weathcred surfaces Of the
diabase.
Alice.
Some locations about quarter of
a mile east of the mouth of Bird
creek are known as the Alice group
Here an extensive replacement de-
posit occurs along a shear zone in tho
middle part of the quantities regarded
as belonging to the Newland oval
lace) formation. 1t Is developed by a
70-foot adit which shows the follow
ing section.
The strike of the several layers here
is N. SO degrees W. and the dip So
degrees SW.
Blue Bird.
On Blue Bird creek near the south
east corner of T. as N, r. E., a
recent discovery known as the Blue
Bird claim was being developed at the
time of visit The shallow discovery
pit was about 8 feet square and locat-
ed in the bottom of the canyon at the
stream level. The top of lode or
pocket of quartz and calcite carrying
considerable chalcopyrite and pyrite
was exposed, occupying the whole pit.
However, development had not pro-
ceeded far enough to show it's thick
ness. The country rock consists of
blush and grayish sandy shales near
the upper part of the strata repre-
senting the Newland (wallace) form
alton.
Along the state line from Wards
peak northwestward on the Montana
slope are a number of mines and
prospects reported as valuable and
promising, such as the Bald Mountain
ST. Lawrence, Buffalo and Wishard
They were not visited for lack of time.

Newland (Wallace) formation is the
Copper Prince, near the mouth of

1t can be followed for nearly third

trends about N. 70 degrees w. and is
nearly vertical. 1t is series of par
allel slopes in highly metamorphosed
shales, representing either Newland
(Wallace) formation or the st. Regis
and is in close proximity to
ntruded masses of granite and mon
zonitic rocks, aplite, and diabase bikes
The chief minerals are pyrite and
