In the Geddes & Bertrand the ore is
tracesble from wide groupings that will
work $40 a ton, on an average, down to the
5O-foot level, where there are large bodies
of ore that will work $50. From that level
down to the 150-foot level the ore is con-
tinuous and Of the same grade. In the
chamber known as No. s, on the $50 level,
they are putting in 10-foot holes and
blasting down the ore in large blocks,
which is being broken up and run out to
the mill for reduction. The chamber ap-
pears to be 100 feet long by so wide, and
now looks like a large cave with ora on al!
sides. The mass OF the ore ia low grade,
$50 ore, with "vuggs" Of rich ore all
through it, streaks of black metal that
will assay as high as $4,000 appearing in
some places.
On the Madeira Consolidated, of which
H. X. Mitchell is President, they are sink
ing a double compartment shaft, now
down 200 feet. They are running a drift
from the bottom of this shaft to strike the
ledge, which crops out boldly on the
surface. This is the first systematic effort
ever made to prospect the claim. The
outlook is encouraging. Five men are at
work.
Samples of ore from the Water Jacket
mine, Secret Canyon, that assay S175 in
silver have been brought in. This mine
adjoins the old Page & Corwin, from
which over S100, 900 were extracted several
years ago. The ore giving out, prospect
ing was discontinued, as limestone forma-
tions were not understood at that time.
Appearances are that the Page q Corwin
is valuable, and the Water Jacket, of
course, also. From the Water jacket,
several years ago, II tons of ore were
shipped to Austin that realized 81 800.
This ore was from an incline, now down
rs feet. There are still small stringers of
ore going off from the main body. from
which the samples mentioned were taken.
The Rescue mine in Silverado District
is closed Town at present. An examina-
ton shows there is still ore going down
from the surface. The failure of the mine
must be attributed to extravaganza and
Encouragement. There are still spots OF
rich looking ore throughout the entire
property from the surface down to the 400
level. The main incline has been carried
down at an angle of 60 degrees, cutting
through a very promising ore formation at
a depth of $50 feet. A double compart-
ment shaft is down 200 feet, and the facili-
ties for thoroughly exploring the mine
through this shaft are very good.
The Queen mine, adjoining the Rescue,
is developing into a valuable property.
The present workings show two veins. one
east and west and the other north and
south. At the point Of intersection on the
l50-foot level there is a body of ore 5 feet
| thick that will work on an average 1926.
tho richest assaying az high as 81. 800.
The Western Globe and Tiptop mines
are being opened up with fine prospects.
An irregular vein of quartz going o 90
feet, the present depth of workings, is o
feet wide and contains ore that can be
worked by smelling or mill process. There
are 100 tons of this ore on the dump that
will work $160. There are deposits of
\ black metal in the mine that will go $4,000.
A tunnel is being run to tap the vein at
the bottom of the shaft.
The Empire series OF mines have a quartz
vein going down with a barely pereeptiole
showing Of ore on the surface. which Wild
ems out rapidly as depth is attained. AT
less than 90 feet a 4-foot vein is disclosed.
This property has been sold to an Eastern
company, who. it ia understood, will
shortly proceed with developments.
The Diagonal ia a claim in this series
having a a. foot vein of quartz carrying
a high per cent of gold.
The Maryland mine on Silverado Noun
tain, being worked on lease by Bergman
& Co., is shipping $50 sacks OF ore to the
Richmond works which will probably so
$3.50 to the ton.
