zBut a few miles east from Grange
}. along the South Fork of the
arwater river, exists a mineral belt
the way from the Dewey camp to
rpster that may in time resemble
mining activities about Butte. in

tie and gain in strength with depth

ferent sections OF the river.
Erhe country In question has been
<ited by eminent geologists. chief
hong whom waldemar Lindgren. un-
~ lately at the head of the u. s.
Illogical survey and author of many
nding articles ON geology and min
Rls. his latest work Mineral De-
sits being considered the very high

In his survey he reports in part on
lis section:
.Finally, along the western foot of
Ia Clearwater mountains, near Harp
Len and Mount Idaho occur states,
<nestones and greenstones, which clear
N form the northeastern extension of

5even Devils and the lower Salmon

&.sThis series is believed to be of early
|<esozoic age and the granite of the
zHearwater mountains Is intrusive in
#Dr. Lindgren has traced the sedi-
&entary deposits in which are the erup-
I've porphyry. which contain these
deposits, for a distance of
DO miles in northeasterly and south
1esterly course, having found them
&here intruding granite had not dis
r'aced them or where they were not
.bvered with the Columbia river lava
|iheet which in some places is 1000
Bet thick. These deposits are particu-
Arly in evidence whene they cross
Be canyons of the Snake. Salmon and
clearwater rivers and the Lolo fork.
u The characteristic feature of the
tortion of the belt where these min
lralized bodies occur is the large area
d greensboro and other schists, which
y bounded on the southeast by a per-
tIstent belt Of crystalline limestone
4hich appears in all the places where
he belt has been followed.
q Mr.. T. J. Bernard, an English mining
4eogolist of authority visited the
clearwater section three years age
md was then highly impressed with the
Xhture possibility of developing gread
bodies of valuable ores. Mr.. Wakely
accompanied Mr. Bernard on his triI
Ind on Mr.. Bernard's advise, he and
1is brothers, located a number Of
4uartz claims near the Joe Baker ranch
bn which they are now doing success
$ul development work, having already
<rosscut the mineral zone over 10(
teet and are still pushing ahead. They
have found some good looking, chalco'
byrite ore with good values in gobC
md copper.
Joe Baker has some promising claims
focated. Further south e. W. oliver
Jim Bishop and Pete Solem have {
humber of claims under development
with most gratifying results and will
fepth are bound to develop rich prop
$rties.
About the Dewey camp, where th'
Rirst mineral discovery was made, thu
most extensive development has beei
ione. which In all represents over 7OO'
#eet in tunnels, crosscuts, shafts ans
ppen surface cuts, so that the exten

IN which occur the large veins
pre-. The Dewey vein averages
feet in width and the st. Patrick ven
Is from S6 to AZ feet between walls.
The Evergreen mine adjoins tn
Dewey and st. Patrick claims on tn
west and Is perhaps the most attrac
tive ore body exposed 30 far.
The ore has been followed into Tn
