finally reaches 10 inches to IL inches 60.
ing west to an upraise. Length of ore
sampled, "a feet.
No. dead, 3 per cent. silver, As &C
ounces; Gold, 0,666 ounces.
The upraise has been carried 20 feet
above the back Of the drift. The length
OF the upraise is feet 6 inches and the
width of ore inches, all of the dark
brown, decomposed variety, with silver
sulphurets scattered through it.
No. 6.-Lead. "a per cent; silver,
357. 80 ounces; Gold, 0,300 ounces.
The ground is solid above the upraise
to the S00.foot level, and the 800 is not
driven beyond this point.
The measurements of the level west
are: From cross.cut to upraise, 32 feet;
length of upraise, feet inches; up.
raise to end, 33 feet; total, 70 feet s
inches.
In the end the quartzyte is much
softened and crumbly, but still main.
tains its characteristic bedded structure.
| North Contact, East, was driven 81
feet by the old company. The ground
is much caved and strongly mineralized,
with streaks Of decomposed ore and
little galena running through it.
| 900 MIDDLE VEIN, EAST.
The driving east and west from the
crosscut aggregates 81 feet inches, the
west end being carried up to the Gro S.
cut, which run. from the west side Of
the shaft.
In the back and bottom the vein meas.
ures feet 6 inches to 5 feet in width,
impregnated with the yellow oxide of
lead, carbonates of copper, and silver
sulphurets. The length of the exposure
carrying this class of ore is % feet
inches. The hardness of the ground
made it impossible to take large samples
with pick and CAD. The sampling, how
ever, from side to side, and as much OF
the length as could be reached, gave.
No. Lead, % per cent; silver.
65 ounces; gold, trace.
In the east,.end of the drift beyond the
, caved ground the face is impregnated
with seams of ore aggregating at the
! widest part 4 feet and narrowing to
, feet in the back. The sampling of the
J 4 feet, not discarding any of the gangue
, gave:
No. S.-Lead. 1875 per cent. silver
1886 ounces. gold, 1866 ounces.
