THE LEXINGTON MINE.
In reporting this mine 1 will start with
shaft No. / which lies $50 feet west of the
Josephine mine. Shaft No. 1 has been sunk
to a depth of 100 feet 20 feet of which is
used as a stump.
The east drift, S0.foot level, has been run
nearly to the line of the Josephine. Thirty
feet east of the shaft the body of ore, known
as the " middle spur,' was struck; this vein
wasfollowed POI #. in asoutheastly direction,
the body OF pay ore varying in width from 4
to ID feet i'll the face the ledge has punched
to a mark.
just east of where the "middle spur " was
struck, a cross-cut has been rum, through
granite and vein-matter, 100 feet in a north
erly direction.
Further along on the SO-foot level the north
spur was encountered. This ore body runs
parallel with the middle spur and has been
followed for about 200 feet, where it pinches
out, the face of the drift now being in gran
lite, with some vein matter intermixed.
At or near the end of the drift on the mid
Gle spur, a cross-cut has been run north, 800
feet, through decomposed granite this cross
cut has developed no ore.
Above this level the ore has mostly been
stopped out.
The S0-foot level, west, is in $40 feet; 200
feet in, il connects with shaft No. 2 at this
point a cross-cut has been run north so feet,
through granite and vein matter, developing
no pay ore. The vein in this drift is from 4
to 20 feet in width Of good ore. Between
shafts No. l and 2, the ore on this level has
been stopped nearly to the surface.
Ninety feet west of shaft No. 1, on the So
foot level, the south spur was struck and fol-
lowed for $50 feet to the southeast; 1852 feet
of this drift was run through ore the vein
here avelaging about p feet in width the
balance was run in granite. A cross-cut was
rum south from the end of this drift, 100 feet e;
nothing new was struck.
The east drift, 110-foot level, 200 feet, about
116 feet in ore this ore body carried a streak
about 2 feet wide of remarkably rich ore the
assays going from POO to 1000 OF. in silver.
Thirty feet from the shaft the middle spur
was again struck and followed 10 feet; the
face is now in low-grade ore and vein matter.
In the bottom of shaft, 20 feet below the
11O-foot level, a cross-cut 20 feet long devel-
oped a body of base ore IA feet wide, which
has not been prospected.
The west drift, 110-foot level, connects
with shaft No. 2 at a distance of 200 feet,
The ledge here is about 5 feet wide, carrying
considerable low-grade ore.
Ninety feet west of shaft No. the south
spun was cut SO feet further on a cross-cu'
was run south so feet developing nothing.
Shaft No. 2 lies 200 feet west of No. l, aut
, is now down 10 feet. The west drift, Is
level, is in 40 feet. Eighty feet west of the
! shaft the ledge swung off to the south carry
ing a streak of ore about 10 inches wide which
, was followed for 60 feet when it pinched to
mark.
; The west drift, second level, shows an Or,
. body from to 7 feet in width, for 200 feet
3 where it connects with the bottom Of shat
No. 3. Here a cross-cut has been run soutl
so feet opening no new body of ore.
Fifteen feet west of shaft No. 2, on thi
! level, another cross-cut is in about 80 feet in
southerly direction. It has not struck any
, thing. The bottom OF the shaft Is Ill pas
ore.
!. Shaft No. 3 is down SO feet, where it con
meets with the I'd level has a cross-cut to tn
= north which is in about 20 feet, showing l
a feet of a ledge of ore which carries quite
heavy percentage of manganese.
The west drift, I'd level, is in 23O feet
" showing a body of ore varying in width
II about % feet being its narrowest and 20 fee
its widest point.
If About 100 feet west of shaft No. 3 a eros;
cut was run north so feet through granite an
~ vein matter the face is in granite.
y Shaft No. 4 is down 26 feet and shows som
1T GOOD ore in the bottom. 1t is estimated tn;
q about 10000 tons of ore have been eXtracte
from the Slopes east of shaft No. 2 and abo'
= the 1st (S0-foot) level.
It will be seen from this report that til
Lexington has been pretty thoroughly pro
pccted above the water level: there has bee
about 800 feet Of prosecuting done, whit
may be called dead work the shafts and lie
IN els have probably more than paid their e
~ penses, being driven mostly in ore. AT Il

t. They are busily engaged retimbering the Il
10 De. levels, removing stulls and replacing the
with square timbers. Contracts have be-
er let for running the 400 and 800 foot leve
lg east and west. There is no change III t

S. 1t is said that a 60-stamp mill will be ere

however, unable to gather any authentic
formation on the subject. AT the

N been no change since my last report.
ISIS The west drift, $50 foot level, is in TIA te
