Mining Items.

operation at the Kildonan c~hlorinatlon
mill at Puma, near Deadwood, is said
to have nearly doubled the crushing
capacity of the plant.
The reports received from Z. c. Ed
die, the m~etallurgist and superintendent
of the smelter at Galena, who is now in
the west purchasing ore for the Edge
mont smelter, are very favorable, says
the Express. lie is meeting with the
finest kind Of success, and the ore sup
ply will be constant and profitable to
the smelling company.
Work is still progressing at the Island
gold mine at Four Mile. The ore now
being mined is said to be Of a payable
character, a fact determined by careful
and thorough tests. A car is 10Y being
loaded at this place for shipment to
Aurora, Illinois. for reduction, which, it
is believed will return a handsome
margin of profit to the owners.
The Cripple Creek Mail, in a recent
mention of the Orphan Bell mine at
that place, now being operated by that
luckiest of miners, Maloney of Dead
wood, rays: Twenty sacks of the very
high grade sylvanite has been saved, or
about 200 pounds, that assays all the
way from $40 to $40 per pound. When
a ton of it is taken out it will be ex
pressed to Denver, and Mr.. Maloney is
confident that it will easily bring $780,
600, or S25 per pound"
J. d. McNickle is the owner of six
claims situated one mile west of Camp
Wesley, near tie Reynolds ranch in
Pennington county, which exposes large
vertical veins of quartz ore, containing
q high per cent of sulphides that yields
in gold from $50 to $50 por ton of con-
centrates, so We are told by a mine
owner from that neighborhood. Al
though there is considerable rock from
which native gold can be discovered,
the main body of the matrix is a con-
centrating proposition. If reports that
are given out recently from these differ
ent camps, west Of Rockford, are sus-
tanned by men looking for that class OF
property, there is no reason to dis
believe that mining enterprises will be
%inaugurated whenever investigations
are made by those hoping to find a safe
investment in Understanding Review.
DEMEREAU MOUNTAIN MINES.
Parties coming in from Pringle report
a marked change in the tunnel being
driven into Demereau Mountain near
that place. The tunnel has now been
driven into the mountain, from the
east side about l73 feet, and III its pro.
gress has cut four ore veins, averaging
in width as follows: First vein, 4 feet,
second vein Is feet, third vein 90 feet,
fourth vein Z feet. Each of these veins
are enclosed in walls of granite on the
one side, and %hornblende and horn
blendic slate Oh the other. The ore in
the different veins thus far encountered
are very similar in character, and give
returns by fire assay of values varying
frora Sl4.i6 to $1,000 per ton in gold.
The ore is 4 sulphide, AMI in addition to
the gold contents carries considerable
copper III form of copper pyrites, but
the per cent of copper has not rs yet
been as~certained. No lead, or silver to
mention has thus far been obtained.
The change referred to is the striking OF
another granite dyke at the depth OF
about 10 feet, when Immediately there
gushed out n stream Of water which is
still running in sufficient volume to run
a 40 stamp mill. The water (as revealed
by tasting is strongly impregnated
with iron, and deposits o yellow sedi-
ment as it flows out Of the tunnel. This
dyke of granite, as indicated by works
on the surface, forms the east wall Of
what is known as the Paymaster vein,
which, though not so large as some OF
the others, is presumed to be Of a much
higher grade, as the ore yielded by
assay at the surface S72 per ton in gold.
This granite dyke is not a large one, and
probably six feet further will carry the
workmen through into the vein. The
floor of the tunnel is at an elevation OF
about $50 feet aboye the level of Beaver
creek, and it was not supposed that a
water vein of so much power would be
found at that heiCht However, If will
he welcomed by the owners Of the prop
erty as it is advantageous in affording
plenty Of water for hosting works and
other useful purposes on the ground.
AS the driving Of the tunnel is still in
progress, we may expect a further re-
port of interest in a few days.
