cross cut on the 900. The west end Of
the ore body on the 1000 is % feet a t
OF the west end Of the ore body $50 e t
west Of he cross cut) galena comes il ,
inches TO 3 inches vide, and widens 20.
ing east tn feet 6 inches, and finally 10
hct inches at the widest patt OF
clean galeno, and then narrowing u 3
feet and holding for width of 2 feet %
to the end of practically soil ore
body. The length of this ore body n
the back Of the drift is 81 feet, and the
average width may be taken at feet 6
inches. As already stated, the me- ou
the 900, which is located 10 feet we It Of
the cross cut, passes down through this
large ore body to the 1000, coming out
in the latter drift "A feet east of the
winze, which is in ore for the entire dis
tance, with the exception of about 20
feet where the ores make over into the
hanging wall. The footwall of porphy.
ry is regular and smooth and has an
angle of about so to S5 degrees. The
vein fer an average width of 2 feet 6
inches was sampled above the level US
far as it was accessible, which was with
IN about fourteen feet of the large open
ing into which the winze out Of the 900
enters; it was not possible to pass into
the opening from the lower level be-
cause blocked by caved ground.
The sampling of above level up to the
cave gave:
No. l3.-Lead, 1910 per cent silver,
1888 ounces; gold, 0, l50 ounces.
Beyond the solid ore the galena b..
gins to feather out into veins inches to
inches wide, and finally to not more
than an inch for distance of 80 feet.
1t would be an absolutely conservative
estimate to place the average width #
galena at 6 inches for this entire dis
tauce. A sample was taken for the en-
tire length and for the full width Of
feet to 5 feet between walls, not discard
ing any of the gargne matter; the result
was;
No. r., Lead, 3 s per cent. sily,r,
20, g ounces; gold, 0 l75 ounces.

SOUTH CONTACT DRIFT.
Length, SO feet 6 inches.-l6 feet 6
inches from the cross cut there is a
winze % feet deep showing II inches Of
solid galena at both ends. The ground
was sampled for depth of 10 feet, the
last 10 feet being under water,
No. l5.--Lead 67 per cent; silver,

This vein was discovered by driving
on very thin contact which was cut in
the main cross.cut. After driving about
l3 feet narrow seam of galena was en-.
, countered which soon widened to foot
in thickness and continues for 81 feet in
the back and bottom of the drift. The
next 80 feet inches are barren: but a.
the breast there are indications Of orc
coming in again.
|, 100 MIDDLE VEIN, WEST,
at the end OF the cross-cut. Just west
of the cross-cut the west end of The
chimney which makes in from the @ ts
comes to an end. The middle vein ba,
been drifte % feet inches to cross
cut which intersect the north contact
This was driven on flor .short distance
when q crosscut was run south which
again cut the middle vein Thin scales
of galena are found on the hanging
wall from time to time, but nothing ver,
encouraging; in fact this is the leas
promising part of the mine between til,
500 and this level.
MIDDLE VEIN, EAST.
Length, 2S7 feet. The ore changes
entirely in character at this point, wher,
1T has become oxidized, brown an,
crumbly, and shows crystalline carbo
nate Of lead (cerrusite) and copper stains
The vein ranges from 10 inches to /
inches in thickness, finally running
down to inches; the average for tn
entire length, 81 feet, Icing 8 inches.
No. l6.-Lead. 1875 per cent; silver
225 ounces; gold, O. 300 ounces.

winze has been sunk to the 1000 Level
