STRIKE IN THE RIALTO VEIN.

STRIKE IN THE RIALTO VEIN.
The strike made in the Rialto vein,
property of the Ridgewood Gold Mining
company, last Tuesday, as developments
are extended in the 600 foot level, where
it was discovered, is improving, both the
breast and floor of that level being in
fine pay. The ore is also continuous in
the 600 foot backstope. A small piece
of ore panned gave s15O in gold. A A.
inch vein OF mineral gave S40O per ton,
while the gouge material alongside of
the crevice gave S3S.7S in gold and silver
per ton, no test being made only for the
two metals mentioned. The OBSERVER
mining reporter Thursday afternoon
witnessed the panning of piece of ore
from the stope which did not weigh to
exceed ounces, that after being pound
ed up in mortar gave showing of free
gold good enough for ounces gold per
cord. He was also shown another pan
prospect from mineral that had been
roasted in the blacksmith forge that
contained coarse gold. This came from
the 4-inch streak of mineral.
Mill ore from the mine is being hauled
to the Bates hill tunnel and loaded into
ore cars of the Boston & Denver Mining
and Milling company, at which mill the
ore will be treated.
STRIKE IN THE PHUENIX-BUR-
ROUGRs
Manager Mccain Of the Kansas Bur
roughs Consolidated Mining company,
has struck fine large well defined body
of ore in sinking the main shaft at that
property, which is down 1910 feet. The
shaft for the last 40 feet has been in this
chute OF ore which continues as sinking
goes forward.
The output OF ore from this property
during July was 375 tramway cars of
stamp mill ore, equal to 3lS7 tons. AS
sinking was going on at the Phoenix
Burroughs shaft, and it being a short
month owing to a number Of men being
off during Fourth of July week, the out
put OF ore was quite large.
STILL ANOTHER srRIHE.
Stephen Hoskin, manager Of the Free.
dom mine, easterly portion Of the Rialto
vein, reports a strike in the 800 foot
east level of that property. The char
acter Of the crevice matter has been
changing ever since the level was start.
ed. A few days ago mineral was found
which has the same appearance as that
which was struck in the 800 foot east
level Of the Rialto. AS there is 266 feet
difference in the elevation between the
collar of the Rialto shaft and the collar
OF the shaft on the Freedom would indi-
cate that this chute OF ore is long one
and continuous. Mr.. Hoskin will have
run made at the stamp mill as also a
test Of the mineral at the smelters.
THE ELECTRIC MOTOR A SUCCESS.
The electric motor received Tuesday
OF last week in Black Hawk, made its
first trial run Monday afternoon. Messrs
Clarence X. Colvin, manager Of the Cook
Gold Mining company, and Melvin p
Dalton OF Denver, both stockholders Of
tuc III bchNtI Allulub anu AullilDs
company, owners of the motor, were
present and seemed well pleased with its
work. 1t developed large capacity,
some claiming for it so horse power. 1t
il now conceded that the motor has suf-
ficient power to do its work.
The company started up its 80 rapid
drop heavy weight stamp mill the morn
ing Of the same day, the motor making
several trips to the mill with ladened ore
cars. In addition to treating the output
OF the Cook Gold Mining company the
Ridgewood Gold Mining company will
treat the output from its Riato mine, as
well as ore from the workings of the
Gregory incline shaft. These sources
will be amply able to furnish $50 tons OF
ore per day, the amount requisite to
keep the stamps dropping when speeded
up to 90 drops :per minute. AS soon as
Manager Colvin gets the blockade OF ore
in the Cook in the mill he will work that
property in full force.
TEST LOT OF ORE.
f. Stefan, manager OF the Geiger
group Of veins on Michigan hill, Pine
district, has quantity OF ore at the mill
OF the Avondale Mining and Milling
company, from the Geiger mine, being
treated Should the results prove salts
factory other shipments will follow from
the same property. This company has
the water rights along North Clear
Creek from their mill for distance OF
six miles above. 1t will be blessing to
the owners OF low grade mines in Gilpin
