Nevada along with a large body of $50
ore. The Gold Anchor has shown a
uniform valuation from $50 to $40, the
ore body increasing in width rapidly as
greater depth is reached.
The rich ores of the district is not a
tellurium but a marcasite in character
and any scientific man will tell you
that this character of ore, when found in
true hssure veins in the arch9an granite,
can be positively figured on going to a
greater depth than man can ever reach,
and still retain its high metal value. Ores
of this special character have been proven
to lay in large bodies with great depth,
and ore has been found to come nearer
the surface in this district than ever be-
fore noted by scientists. This undoubtedly
indicates that large bodies of this bonanza
ore lay at a greater depth than has vet
been reached in the district However,
there has not been a shaft or tunnel drift
yet sunk or reached vertical depth of
100 feet but what has shown strong indi-
cation of marcasite ore, or the ore itself
in small lunches Wherever this ore has
been found it has invariable assayed
better than $500 per ton. 1t is believed
that as the mines reach to a greater depth
that marcasite will become the charactistic
ore of the district.
In the Alice mine there is found small
pockets of grey copper ore that will aver
age over S. 900 per ton in gold and silver
values. 1t is thought that greater ex-
ploration of this immense mass of mineral
will bring to light either a shoot or Chin
ney of high valued ore The Alice ore
is pyritiferous porphyry that will aver
age nearly $5 per ton in gold values,
while the mountain traversed by veins or
he Of frrV,1 f,D fa,,
feet of copper pyrite ore that will aver
age better than SI2 per ton. This mine
has not been worked for several years on
account of too much 'expertism," " but
it is about assured that a new manage
ment is to take hold of the property, that
has had long practical experience with
low grade ores, and some common sense
as we'll. 1t is believed that the electro
chlorination process, now in successful
operation in Boulder county will treat
this ore successfully. 1t is probably a
thorough test will be made on this ore
at the Boulder mill during next month,
and if proven successful, their large mill
will be remodeled TO use that process.
The same character of ore is found on
Fall River in large veins as the Alice. The
Alice Extension has opened large body
of this pyritiferous porphyry in their
QT1NSH III lIOu1 Fdll H(lNGI at a
greater depth than has been reached in
the Alice workings, with the result that
the ore is of a higher grade-averaging
So per ton. Across the gulch Freeman &
Moore have opened a large vein in the
Gold King and have built mill on Fall
River to handle their product with the
result that the ore has averaged nearly
S. per ton on the plates besides their con-
centrates, which they estimate will give
the ore a value of $I2 per ton. Their mill
and mine has recently been started with
full force, ana they are treating twenty
five tons daily. The big success made by
them will encourage others to build
The Gold Anchor shaft is the only one
SO far that has reached below the water
or ground level of the district and has
undeniable proven the opinion advanced
by some of our miners that our big values
and ore bodies would be found after that
point had been passed. The vein is now
all of ten feet in width and the entire vein
