ours as seams, bands and lenses In
the sheared slate. The ore contains
sphalerite with a subordinate amount
of argentiferous galena, with which is
associated much pyrite, and some-
times little gold. The typical ore
Is an intimate mixture of the sulphides
recurring extremely fine grinding. The
principal mines are the Jefferson,
Idora, Tuscumbia and Red Monarch.
Osburn.
The Evolution district includes the
Big creek watershed and some terri
tory on the north side of the south
fork of the Occur d'Alene river. The
district lies half way between Osburn
and Kellogg on the O.-W. r. & N.
The principal prospects are the Polar
is, Yankee Girl, Yankee Boy Big
Creek, Western Star, Trojan, Silver
ado and Rhode Island. Considerable
exploration and development work is
under way, but as yet no important
producing mines have been developed.
Shoshone.
Z The Shoshone district, which lies 10
miles southwest of Paragon and five
miles east of Murray, is reached by
the Murray branch of the O.-W. r. &
N. through Enaville. The principal
mines and prospects are the Terrible
Edith, Monarch. Paragon, Black
Horse, Bear Top and Orofino. Devel-
opment work has been under way at
most of these properties during 1916
1917, and considerable ore has been
shipped from the district in the past.
Slate Creek.
The Slate creek district, which lies
Is miles south Of Wallace, is one of
the most inaccessible in the Occur
d'Alene. 1t is reached by trail from
Wallace. The geology is similar to
that prevailing throughout the Occur
d'Alene. The sediments are intensely
folded, and faulting is in great evil
dence. Intrusiyes are numerous. AT
the present time there are no produc-
ing properties in this district, but
there are many prospects and consid-
cradle development work is being
done.
East Occur d'Alene.
The East Occur d'Alene district lies
on the outskirts of the Occur d'Alene
region. 1t is reached from ST. Joe on
the Chicago, Milwaukee & st. Paul
railroad. The ore deposits consist of
veins in brecciated zones along fis-
sures in Algonkian sediments chiefly
quartzite. Copper ores predominant
the chief minerals being bornite ana
chalcopyrite The deposits generally
have heavy gossans. The Black Prince
is probably the best known of the pro-
perties in this district.
Bald Mountain.
The Bald Mountain Monitor, st.
Regis) district is outside the area US
ually included within the Occur
dAlene region. 1t lies in the Bitter
Root mountains and extends into
Montana. The district is reached
from Saltese, Mont, or from Lookout
both stations on the Northern Pacific
railroad The Chicago, Milwaukee &
st. Paul railroad also touches this dis
trict. The ore deposits, which are
veins along fault assures are valu-
able for copper. The ores carry about
O.02 ounces gold to l per cent of cop
per. The principal mineral is chal-
copyrite. The most important mines
are the Richmond Monitor and Bald
Mountain. Other properties are the
Buffalo, Park, Springfield, Champion,
Eagle, Bullion, North Star, Alpine and
Ledoy The mineral deposits lie in a
belt along both the eastern and west
ern slopes of the Bitter Root divide,
which forms the Montana Idaho boun-
Diary. The Richmond is now being
worked and has recently attracted
considerable attention. Several of the
other properties in the district were
