Marshall Lake District.

7. Tuttle. one of the owners of
mining property in the Marshall lake
district, has just given out the follow
inc interesting statement of conditions
IN that richly mineralized zone:
marshall lake lies in the breaks of
tho main Salmon river, % miles north
If Mccall and II miles from Burgdorf.
The formation Is one of the most high
" altered and metamorphosed districts
TO be found anywhere. The country
rock gradates from micaceous schist
to almost solid silica as depth is at
tanned.
Claims were located in the camp a
good many years ago but little was
done in the camp until Mr.. Holt be-
gan development in a small way lit
tie more than one year ago. Mr.. Holt
has driven two levels the depth of
which is approximately 200 feet. From
the lower level he has sunk a winZ.
He has drifted on his ledge in the low
er level about 2S0 feet and the upper
level, not quite so far. The ore lies in
lenses, swelling and narrowing as
drifting ON the vein proceeds. In some
places the vein is only a few inches.
In others 1t has swelled to 10 feet, the
general average being somewhat like
three and one-half feet.
Construction of Mill.
"Mr. Holt began the construction OF
mill the first day of September, last
About Oct 20 he started his Lane mill
and since that time has produced Oh
the plates a large amount of bullion
The exact amount am unable to state
but several shipments have been sent
out, one of which / recall, of 1852 lbs
Of amalgam, the first shipment of one
weeks run, amounted to $24,
"The ore is largely free in character
which makes the district what yoJ
might term a poor mans proposition
Small equipment and large returns viii
be the record of Marshall lake.
There is little development in the
camp aside from the Mt Marshall
which company has driven a crosscu
tunnel 100 feet driving for their veiI
which will be reached, according t.
the survey, at a depth of several hun
dred feet The tunnel cut one vein a
depth of 900 feet, which panned, bu
the large vein is on ahead.
Fine Showing of Ore.
The other development so far thi
winter has been carried on by j. Il
Eldridge of Boise, ON the Summit-Tri
angle group, adjoining Hollis property
The Summit Triangle property has a
nne ore showing as there is in TIL
camp and 1t Is the opinion Of thos
familiar with it that 1t will develo
lnto as good a property as the Hol
property
Marshall lake is high grade cam
ana | predict that it will make on
OF the best mining districts in tn
west. The results at the Holt proI
erty has demonstrated the fact tina
tne Lodges tend to widen with dept
and every indication points toward th
proposition that the values are goin
% go down and the veins maintai
their richness to good depth
IL has been suggested by compt
tent authority that the fissurings c
une district are probably the resu
u a syncline fracture, due to the III
MI OF the Secesh range lying immed
ateiy to the south, thus breaking til
VEINS from underneath, which, if tru
MOULD tend to give them great dept
Inc development at Hollis propert
supports this theory and the formatic
anu development on the Summit-Tr
al,sie bears out this theory to a mari
