of claims near Sunshine, owned by the
Golden Bar Mining company. The
claims are being actively developed by
the ineorporators, many of whom are
Camp Floyd men, whose confidence in
their property, already great, is increas-
ed by Professor Jones report, a copy
of which is given below. The company
is doing its own work and is offering no
treasury stock. The following is the
report:
This group of claims lies on the west
ern side of the Camp Floyd mining dis
! trfct, and on the eastern side of Tooele
Valley, about a mile and a half north
west of the Sunshine mine. 1t lies in
the very edge of the hills, and can be
approached by a wagon road without
/ difficulty. The formation is of blue I@ne-
(! stone belonging to the carboniferous
period, and the strata dip gently to the
southwest at an angle running from ten
to twenty degrees. In the gulch where
the shaft is found there is a porphyry
dyke about fifteen feet thick so far as
it is exposed, which seems to dip across
the formation to the north, but is more
likely to follow along the bedding to
the southwest. Underneath this por-
phyry dyke the country rock is broken
up to the depth of ten to twenty feet,
the upper part being composed of
rather small pieces, and the lower part
of large boulders. Between these bro
ken pieces where the shaft goes down is
a vein of mineraIized material about
two feet thick, which carries a very
little gold. 1t is my opinion after the
direction of this porphyry dyke Is dis
covered that underneath the porphyry
will be found a body of broken lime
stone rock of varying thickness which
is liable to carry mineral. The explo-
ration so far consists only of an open
cut ten or fifteen feet long, and a shaft
at the end of the cut about twenty-five
feet deep, which cuts the porphyry
dyke, and goes down into the lime
stone some twenty feet
The proper way to develop this prop
erty is to run a tunnel into the hill
where the open cut now is until the
porphyry vein is cut through, and the
underlying mineralized zone is fully ex-
posed After this tunnel is run it may
be necessary to sink an incline under
meath the porphyry following its dip
in whatever direction it may be proved
TO go. This will open up the ore bodies,
if they exist, and can be done at
reasonable expense of time and money.
Of all the properties which I have
examined west of the Mercur divide,
this has the best showing, eX-
cept the Sunshine mine. and if any
ore bodies are ever likely to be dis
covered in this region 1 think they
will be found in this mine, and there
fore [ do not hesitate to recommend
a thorough exploration of this proper
ty. Since the shaft is located on the
edge Of the mountain, the distance to
the water level is less than on any
other claim that [ have examined, and
it is therefore more likely that you
will strike the ore bodies which exist
on or near the water level if they are
to be found in any part oft his camp.
The occurrence of porphyry in
mines of the Mercur district is
matter of the greatest Importance
since no paying mines have been
found outside of these porphyry dykes
which follow along the bedding. This
is the first outcrop of porphyry which
[ have been able to identify outside
many claims on this side of the range
which go from so cents to 81 in gold
that show no porphyry anywhere, and
therefore it is very difficult to follow
the veins or to know where the ore
bodies are to be found; but in this
particular case the porphyry is known
to exist and can always be followed
| easily, and the ore bodies developed
at the least cost. This is why 1 con-
| slider the Golden Bar mine to be the
most important of any of the claims
! on the west side of the range, with
the single exception of those on the
! Sunshine vein.
