has recently attained a depth of 145 feet, a
crosscut north has been extended TO ascer-
tain the width Of the ledge. At a distance
OF Is feet from the shaft the hanging wall was
struck, showing ore all the way, and in
places exceptionally rich in silver and carry
ing 40 per cent. copper. The south or loot
wall has not yet been reached by a c~rosscut,
so that the full width OF the vein is not
Known. 1t. appears, however, from the result
OF the first crosscut that even though the foot
wall is close behind the shaft, the width of
the vein at a depth OF 145 feet as compared
with that near The surface shows a very great
increase. Sinking will probably be resumed
shortly till the snfat is deep enough to connect ,
with the Yves: drift of the main workings. In
the whim shaft the first level is yielding con-
siderable high grade free ore from a ~six-foot
vein, clean and compact. From the bottom
of the shaft, at a depth Of 100 feet, the face
of the west drift has been advanced to a total
length of 100 feet, with no material change
in the aspect Of the ledge, which has been
highly encouraging ever since the ore body
was first encountered. This drift will be
continued to a connection with the whip
shaft, and will open up all immense amount
of high grade silver-copper ore for stopping
purposes. The east drift, 100 feet deep, is
not at present being worked, nor has the east
drift in contemplation from the bottom been
started, as the hosting capacity OF the whlm
is not deemed sufficient for more extended
explorations.
On the south vein operations continue act
i've, and as the Clipper mill, which is now
undergoing repairs, is not yet ready to begin
the reduction Of ore, the dump is steadily in
creasing in size, containing already $50 tons,
which amount is being enlarged at the rate
of IS tons daily. The ore is free, has an av-
verage assay value of $35 per ton, and is of a
character best adapted for cheap and profta-
Bile milling. AS to the amount of this kind
of ore in sight, it may be stated to be practi-
cally unlimited. The vein is exceedingly
} wide, and has been shown by a series OF
shafts to extend almost from one end of the
claim to the other. Such, indeed, are the
promising dimensions of the ledge and the
improved quality of the ore, that the doub-
ling of the stamp capacity Of the Dexter mill
is now in contemplation.

This sterling mine continues to be worked
with energy and success, which has charac-
terized its management ever since Mr.. Lacaf1
took command. The lower west level from
the within shaft has reached a length Of 60

ton, retains all its indications of perma-
, nence, being well defined and showing nc
r proportion of worthless ledge matter so often
seen in other mining properties. The slopes
in the TO- foot level are in ore and are produc'
west of the shaft on this level q shaft is now
being raised, being already halfway tc
the surface, and leaving about IS feet yet to be
stopped. \ yesterday a contract was let for the
construction Of a new whim, which will be
y ready to begin the work of sinking what viii
' constitute the main shaft as soon as the pres
ent upraise is carried to the surface. Tit
new shaft, which will be much larger than the
one which now serves the purpose of a mail
shaft, will be sunk as far and as fast as the
hosting capacity OF the within will admit. ant
