the Ssukey-is worthy of mention. It is
owned by ,Noyes and others, and though the
shaft " only 25 feet deep, the vein is large
and is rapidly showing up a good body of
fair ore, heavily ~impregnated with mangan-
esq.
The Moose,
Located q short distance southeast of the
sankey, is oneSof the most promising prop
critics on the hill. 1t is at present leased by
Wright, Mahony & Co, and is developed by
two shafts. The main or perpendicular
shaft has been recently started about
thirty feet east of the discovery shaft
(Which follows the vein on an incline)
and is calculated to tap the ledge at a depth
Of so feet. In the old shaft the vein is be-
tween three and four feet wide, and has
yielded a considerable amount of ore, assays
of which show from 90 to 100 ounces per ton.
Thirty-tive tons Of high grade ore were re-
Gently shipped to the smelter, and other and
heavier shipments may be expected to follow
as soon as the ledge is reached through the
new shaft which will probab..v be some
time during the next week.
The Chief Joseph.
Thus far the above named mine is a mere
prospect, and can not be rightly classed as a
mine. Enough work has been done however
to give the boys strong hope of a bonanza.
During the past week a new shaft has been
started 800 feet east of the discovery shaft. 1t
is down only a short distance and shows a
four foot ledge filed principally with ore of a
somewhat low grade, which the owners are
confident will improve. Considerable fair
grade ore is on the dump. The development
of the
Gray Rock
Is progressing favorably. The ore in the
lower workings of the mine continues to be
of a base character, but is sufficiently rich to
pay well for extraction.
The Mountain.
This mine, which is a copper one, owned by
the New York Copper Company, of which
Mr.. Meader is superintendent, is at present
the scene Of much activity, both on the sur
face and underground. Yesterday from the
bottom Of the main shaft a drift was started
to run in on the ledge eastward where some
rich copper ore will be extracted. That in
which the percentage of copper exceeds thirty,
is being sacked and shipped East for reduc-
ton, while the lower grade ore, of which
there is great abundance, is piled on the
dump where it will remain until the compile
ton of the smelter renders it available for
reduction. Fifteen men are at present EN-
ployed and from ten to twelve tons of high
grade copper ore is the average daily output.
AT the Colusa, belonging to the same compa-
ny, there are no new developments to report.
A heavy volume of water was encountered a
few days ago which to some extent retarded
operations, but the delay will be only tempo
rary.
The Burnett.
Heretofore this mine has been remark
able for extent rather than richness, but the
indications now are that it will soon be re-.
markable more for richness than extent. The
property is at present leased to Messrs. Clark
IL Rainstord, who are working only a small
tolc1. 1t is developed principally by a tunnel
connected with the surface by an air shaft.
At a point about $50 feet distant from the
mouth OF the tunnel a level has been run,
through which a great deal of Stopping has
been done. AT a point about so feet east of
where the tunnel tapped the ledge, the latter
opers up to a width of fully , hteen feet,
and neither foot nor hanging W. has yet
been discovered. The ore is low grade, but
pays we'll Tor working. Near the west end of
the level, q 15-foot cross-cut has been run to
the south and shaft recently sunk to a depth
Of 40 feet. This shaft passes through the
ledge at present being developed, and within
the last few days has begun to uncover a new
ledge in the bottom, which so far has developed
to a width of six feet, of free milling ore. No
assays have yet been made, as until the width
of the ore body has been ascertained no fair
sample could be got. Superintendent jam
ison, however, is confident of its richness, and
through the MINER will soon make known
the extent of his find.
