have returned. A few. however, have
pushed in farther east toward Elk
mountains. Last week there was an.
other rush to the Bruneau, near the old
mine in Taylor's Pocket country. just
a few miles from Rowland, and there ia
talk Of organizing another mining dis
trict there, the meeting having been
called for the 2Sth Of this thrush.
Mining Companies At Work
Quite a number of companies have
been organized on Jarbidge properties,
some of them with large holdings. But
little development work is under way
as yet, although several have very good
surface showings. The North Star
Mining Company owns the original
Bourne strike on the North Star claim,
and has II claims altogether. The rhy-
olite dyke outcrops on the North Star
about 60 feet wide, 200 feet long and so
feet high. Some rich spots are found
in this cropping. A tunnel is being run
in under the bluff and Is now In over 90
feet. The rhyolite is filed with quartz
and white tale, and IL is an easy matter
to pick mp ore showing fine ,colors OF
free gold to the eye, but most of 1t pans
much better than it looks. Some spots
are quite rich and show q very long
string Of gold in the pan from only q
small sample. and assays are obtained
mp to IS. 900 and $1,000 ton. The av.
erage can not be determined, as they
have not crosscut except in one place
for about 10 feet.
The Arizona Claim
The next best showing property at
present development is the Arizona
claim of Pavlock and Thourot, best
known as the .Pavlock" claim. Here a
shaft has been sunk 25 feet in soft,
granular dyke, and some very good PAN
nings can be obtained from the dump.
This claim has been bonded. Pavlock
and Thourot have another group of
claims above the Arizona upon which
they are working now, aud from which
they obtain some good ore. The Paw.
lock is south OF the Bourne. In the
next gulch and southeast of the Pavlock
is the Pan claim, with short tunnel, also
under bond. This shows some gold.
Still further southeast and higher up
on the hillside are the Pick and Shovel
claims. known as the Escalon property,
but now owned by the Twin Falls Jar.
bidge Mining Company. Here another
rhyolite dyke outcrops similar to the
Bourne dyke. and it also pans in places.
Jarbidge- Bunker Hill
The Bunker Hill and Sullivan claims
of the Jarbidge Bunker Hill Mining
Company extend down the hill south.
west from the Pick, and cross the river
near Pine Creek. The best showing on
this group is at point between the two
streams. where there is some very good
ore.
Southeast of the Bourne. and consider
ably above it, are the Vulcan claims OF
the Jarbidge Vulcan Mining Company.
and here gold can be obtained from sur.
face rock.
Northeast of the Bourne is the prop.
erty of the Jarbidge Consolidated Gold
Mining and Milling Company, consist
ing of the Alice and several other
claims. On the Alice they have found
gold in the surface dirt. and are indus
triously trenching to find the source OF
this gold.
West from the Bourne, on the ridge
between the Jarbidge river and Bear
Greek, is the property of the Belmont
Jarbidge Mining Company. Here they
also have rhyolite dyke and can get
some gold. They are running tunnel
from the Bear Greek side to cut the ore
chute.
The Jarbidge Chief, next to the Bel.
mont, is also working on the Bear Greek
side. The Hilltop Mining. Leasing and
Development Company is pushing work
on its several claims in order to obtain
patents to them, as these claims cover
most OF the townsite Of Jarbidge.
Mineral Area Extending
AS the snow settles so that prospect
ing can be carried on up the river to the
south, gold values are being found for
several miles. Some values are also be.
ing found on the upper part of Deer
Greek. This shows quite an extent of
territory that gives promise of future
development.
The mineral belt seems to be confined
to the porphyry and rhyolite. and the
ore occurs in those rhyolite dykes
which have considerable quartz. The
gold occurs mostly free near the surface.
There is also some silver, and the richer
ore has a small amount Of telluride.
This rich ore, when blistered, shows
more silver than gold. The probabili-
ties are that with depth the ores will
become sulphides. which is a promising
as it would be guarantee of
greater permanency of values.
