DIVIDE FORMATION
ANDESITE-RHYOLITE

J. L. Workman returned yesterday
from Winnemucca and went out last
evening in his ear for the new camp of
Divide, says the Elko Independent. He
was accompanied from Winnemucca by
his wife who will remain in Tuscarora.
Mr. Workman brought with him
surveying outfit and viii survey his
claims in the new camp.
He also brought along his ASSAY out
fit. He already has an assay office un-
der construction.
And what is more to the point for
the present, he took with him bundle
of new lease forms. The ground is be-
/ ing divided up into blocks of 300 feet.
i As there are seven claims in the San
Juan group owned by Workman and
Davis, this would make room for fifty
leasers. But the owners are reserving
certain ground for development by
themselves
The leases run for one wear, with Il
second year to work the dumps. The
royalty is ID per cent on all ore up TO
$3.50 a ton. Over $3.50 a ton the royalty
is 25 per cent
| Mr.. Workman in an interview with
the representative OF. the Independent
said the Divide district was undoubt
edly an extension of the Tuscarora
mineral belt
This belt nuns from Tnscarora north
west four miles beyond Divide, making
total length of twelve miles. IT is
! four miles in width Mr. Workman be-
leves that this whole district is min
eral bearing and that more than one
mining camp will be established with
in its borders.
The formation Mr.. Workman describ-
ed as andesite and rhyolite, with a da-
cite in between. The ore is ebert
quartz and is a replacement of the rhy-
elite.
| That country, of course, is all vol
eanie and on one time there has been a
great upheaval. Tt was this that made
the range of mountains. On the map
this range is shown with a trend north
west and southeast.
| But the vein system runs in just the
opposite direction. that is, northeast
and southwest. Thus the veins have
crosseut the range at right angles TO
it,. That district at one time was COW
eIed by a great inland sea or lake.
There are along the southern rim the
remains of ten distinct sea beaches

northern border has not been recon-
nOitered for these sea beaches.
Then came the great upheaval that
made that range of mountains and fis-
sured the formation These assures
were filed with the hot water solutions
carrying their metal burden, which
eventually became the present ore
bodies
| Most of these fssures are now hid
den with an overburden of wash two
to fifty feet in thickness Thus it will
take much prospecting to find the
veins, tnd there is no wav of estimat-
| ing their number.
| Mr. Workman when he came cut last
week had with him his aneroid and
took the elevations Divide itself has
an altitude of 100. Tuscarora $3.50,
and the mountain in between is S,100
feet high. On a direct line over this
riountain it is eight miles from Divide
to Tuscarora.
| IT is about twelves miles by the way
| Of the wagon road and this runs over
the mountain. To avoid this mountain
one can go six miles north of Tusca-
rora and ascend Cottonwood Creek TO
the summit. The distance this way is
about Is miles.
| Mr.. Workman SAYS the first neces-
sitv of the camp at this time is a good
read. He saws with very little work
| through five miles of canyon into
Squaw Valley good road can be con
sirueted down to Rock Creek, leading
to fe,iheuse ten miles east of Golconda
in Humboldt county.
But Mr.. Davis declares Divide would
prefer to do its trading with Elko.
Divide as vet is medley of tents.
| No ATTEMPT has been made to form q
town and lay out streets. The tents
ere pitched on mining claims.
There is a good site for a town and
there is good water and plenty of wood
/ for fuel. This is cottonwood and aspen.
But twenty miles north there is fir for
mining timbers.
| Most of the Divide country is under
lease from the government by the Col
eGnda Cattle company at % cents an
acre. But the government has reserved
the mineral and ii is all open to pros
pectors.
The lodges at Divide have great
width, ten to twenty feet. The best
ere is very high grade. running thors
ara ounces in silver and $3.50 in goli
The surface showing is most encour-
aging The greatest depth is about 20
feet in the Trimbath lease. When Mr.
Workman came ont the tunnel on this
lease was in seven feet of high grade
ore.
The only question now to be deter
mined at Divide is the depth of the
veins. This of course takes time. But
no mining camp in Nevada ever start
ed out with better prospects.
