| worked even since 1871. 1t is stu
ated on the main lode of the district
200 feet northerly of the famous Old
Telegraph mine. The property con-
sists of two claims. Yosemite and
Yosemite West Extension. These
claims cover 2,40O feet of the vein.
The main incline is down nearly
900 feet, with a good track all the
way. The pay streak in the vein
averages two and a half feet,
though in places it is from eight to
ten feet wide. In quality the ore
runs from 80 to IS per cent. lead and
IA to 20 ounces silver per ton. The
vein covers the whole bottom of the
incline and at this point carries
some pyriteS. a good man-Way
follows the incline all the way down
from the surface. The first level
was opened at fifty feet below the
surface. The east drift was adj
vanced on the vein 600 feet and the
pay streak of the latter averages
three feet in width and Of very high
grade lead ore. The west drift is in
100 feet and the pay ore in the vein
runs from four to five feet in width
and carries a little higher in silver
than that found in the east drift.
At 100 feet the second level is
opened and the west drift run GOO
feet following well defined four
foot vein; in places being from seven
to ten feet wide Of vein and vein
matter. The east drift is also in
nearly 600 feet, the pay ore in the
vein averaging four feet in width
and carrying 80 to 70 per cent. lead
and 20 ounces in silver. The stopeS
from this drift connect with the
ffty-fOot level and for long time
from 200 to 400 tons of ore per
month was extracted from them,
averaging 70 per cent. lead and from
10 to 20 ounces silver per ton. The
Slopes from the west drift also con-
meet with the ffty-fOot level and the
grade Of ore extracted is the same
as that taken from the slopes of the
east drift. From the face of the
west drift Wine has been sunk on
the vein fifty feet, the latter averag-
ing four feet in width and the assay
value OF the ore being 6S per cent. |
lead and 20 ounces silver. A drift |
was run $50 feet on the vein and |
over 800 tons Of excellent ore stoped |
out.
The third level was opened at 10
feet and the west drift run 700 feet
On a well defned'Yein showing from
three to four feet of fine pay ore:
though in places almost double this
width. A large amount of very rich
1re was extracted from the slopes.
The east drift is in 800 feet. follow
ng vein which shows three feet of
pay ore, which carries 20 per cent.
cad and ID ounces in silver per ton.
The Slopes are opened to the 100
DOT level and thousands of
,ons Of rich ore extracted.
About 100 feet further down an
)theT level was opened and the east
lrlft is in 500 feet, and the vein
averages four and half feet of fair
IRE. The slopes connect with the
evel above and very large amount

lrift on the vein is in 500 feet, and !
he pay ore averages a little over
hree and half f7et in width, and S
n grade is considerably higher in {
liver than that found in the east
rift, though the same in lead. About !
100 feet IN the west drift from the &
ncline Wine was sunk fifty feet {
n the vein. From the bottom of
his Wine drift was run twenty
eet east and twenty feet west on

Three hundred feet westerly from V
