The President and Directors, The Sill
yer Plume Consolidated Mining Com
pany, Denver, Colorado.
Gentlemen:
| beg to hand you herewith an ad
| interim report on the conditions and
developments on your properties for
| the past six months.
| The main development tunnel on
your Brown Mountain property was
started on the 1st of August last and
is being driven as rapidly as possible
under present conditions. All work is
being done by hand until such time as
the power plant is installed and pro-
gress is necessary, not as rapid as it
will be when air drills are Installed.
The breast of the tunnel is now in
165 feet and all Indications show that
we shall intersect the first or Ruby
Silver Lode at about 1876 feet, the ap-
proximate position shown by the sur
face survey.
At so feet from the mouth of the
tunnel blind vein was intersected
This vein showed values in gold sill
yer and lead and the fluorine spart
showing is a certain indication that
high values will be obtained with
depth The development of this vein
will be undertaken in the near future.
The main tunnel is being driven in
position ideally situated for the de-
velopment of rich ore in the various
veins as they are intersected. 1t is
situated centrally between two of the
porphyry intrusions which are as
much in evidence on this property.
The strike of the porphyry is parallel
with the strike of the tunnel and
across the strike of the known veins.
The influence of these porphyry intru-
sions on the naturalization of the
veins in this district is undoubted, and
in this particular case, l am of the
opinion that mineralizing influence Of
these two dikes will extend over the
whole of the territory between them
and that we can reasonably expect to
find rich ore extending approximately
100 feet east and west of the main
tunnel, in each vein we shall inter-
sect.
Development work on your Collins
property has been confined to the
proving of the ore body above the
present tunnel level. A vein three
feet wide, carrying high grade silver
lead ore carrying values over 100000
per ton, on each wall and the interven-
ing milling ore, is shown by mill tests
to carry values averaging $500 per
ton. The pumping plant to de-water
the lower level will soon be IN opera
tion as soon as the water is out. lndi-
cations point to the development, on
the lower levels of larger body of
higher grade ore than we have above
the tunnel level.
The Collins ore is a perfect cOncen-
trating ore and there will be no diff
Guilty in recovering the values eco
nomically by the process decided on.
Work on the Lone Wolf property II
discontinued for the present. In
view of the ore now in sight in this
mine and in the Snowdrift dump. q
tonnage sufficient to run the proposed
10O-ton mill for at least five years
considered It better policy to concen-
trate all the work on the development
of your other properties, and this has
been done.
During the past six months numer-
GUS mill tests on the Collins and
Snowdrift dump ores have been made.
These tests have served a dual pur-
pose. They have established beyond
doubt the fact that the high values In
the Snowdrift dump are consistent
and the value H4,50O.OOO) placed on
the dump is conservative, also that
with the mill as designed we can ex-
tract from your ores higher per-
centage of their values at more rea-
sonable cost than any yet obtained In
this district. Z.
Just as soon as the mill is running
you will have dividends in sight, and
| strongly recommend you to take the
erection of the mill under considera-
tion Immediately.
Respectfully submitted,
