| Nine miles north Of DpLamar a gran
its belt, two to four miles wide, begins
and extends to Reynolds creek, abont
the mouth OF Dobson creek, near the
old toll gate on the stage road. Several
years ago Sam BeigIe, who died last
winter in Silver City. discovered in this
granite ledge of gold bearing quartz
which afterwards became the property
of T. w. Jones of De eLamar. Some pros
| pecting was done on this from time to
time and assays proved the rock to be
quite rich; but as it carried arsenical
| iron and eulphurets, and could not be
work ed by the ordinary amalgamatlon
process, it attracted but little attention,
and but very little more prospecting was
done there, although three or four other
claims were located. Last fall DoLerfy
and Morgan went over there to do as
sessmsnt work for Jones. and while
there located some other claims and
brought samples of the rock to Della
mdT. uSoc W0iO buOWh W 'fi+ AeCth
enburg, superintendent of the DeLamar
Co.'S. mill, and to other parties, and Mr..
Reikenberg began experimenting with
them, and attained such satisfactory re-
suits in saving the gold in them, by
leechipg process, that be and SOME other
DeLamar men became interested, in
vestigated the Dohsrty & Morgan prop
erty and took bond for It's purchase.
They continued development work all
winter, running tunnel one hundred
feet on The ledge and then, going down
the hill further, run second tunn
two hundred feet and one hundred feet
below the first. They have put in
Huntington mill, roasting furnacs.ag
itators, leeching tanks, etc., and started
to work the rock last week. The pro-
sess consists of first reducing the rock
to pulp in the mill, then roasting it;
then, 10 cylinder agitators, thoroughly
mixing it with the chemicals used to
dissolve the gold then drawing 1t into
tanks and leeehing out the solution and
saving the values in it by iltering
through charcoal then burning the
charcoal to save the bullion. The chem
icals used and the full details of the pro-
cess, while not kept as a secret, they do
not care to have published, as the whole
business has not yet passed through an
experimental stage. Mr.. Reikenberg
is, however, very confident of success
in making close saving of values, and
probably by this time would have been
able to give results of run had he not,
unfortunately, inhaled a week age,
fumes from the agitator while charging
il, which temporarily incapacitated him
and delayed work.
The ledge open ed on this claim is Pc
euliar in character. The highest values
in the ore appear to be carried in red
dish brown, partially dscomposed
quartz, of which the greater part of the
ledge is composed, but in the same weir
are seams of very heavy iron sulphurets
in masses rather than in crystalized form,
and in this considerable gold, from
which assays running from fifty to sew
sral hundred dollars a ton are made.
The reddish brown quartz mentioned
above runs fifty dollars and upward per
ton. An examination of the ledge at
various places and in both tunnels will
hof tho nj u
of high grade ore is there, and that ifI
the solution of the problem of saving
the values economically has been solved,
the mine will prove very valuable
producer. This same ledge can be
traced by the groupings distance of
fully three miles, and the whole of this
granite formation, for at least one mile
wide and not less than four miles in
length, or clear from the "rooster
comb" an enormous porphyry upheav-
al, which takes its name from the fact
that it's shape is similar to cocks
comb, which forms the southern bound
ary of the granite, clear through to
Reynolds creek, appears to contain
veins of the same character. The King
mine, Sam Bicycles original discovery,
is fully three miles north of the mine
upon which the mill is located. Pros
pectors are busy all over this granite
district and great many claims have
been located. All of the veins carry ore
Of a character similar TO that upon
which the mill is now working, except
one or two locations on the northeast
side of the granite belt, where honey
comb quartz has been found, very SINH
