to h original cost of the plant, and
the amount of oil and b~y.products
that can DO extracted from a known
deposit of shale. the contents OF which
have been carefully sampled and
tested. It Is also a simple matter 10
calculate the available tonnage Of
workable shale in a given area, espe-
cially il n diamond core drill is used
to sample the underlying beds. While
the shale oil production may not com.
pletely take the place of our dwind.
ling petroleum supplies, 1t is reason.
able to expect that the very near
future win see shale oil extraction
plants with millions of dollars in
vested and employing thousands OF
workmen. The scientific end of this
business is one that should interest
some of our ambitious young men.
This will become a great industry and
will have ample room at the top for
good men.
Copper, Iron and Iron Associates.
The greater portion OF the iron de.
posits of Wyoming are hematite. In
many places q considerable mou

Donates. usually in pockets. while the
iron occurs in the shape of a lens.
In 1919. the latest available sta.
~tistics, the iron production was little
short of a half million tons and the
copper production for the same year
was somewhat above eight hundred
tons.
There are vast deposits Of iron in
practically every mountain range Of
Importance In the state and 1t has a
large association OF other minerals.
Eight miles west Of Iron Mountain
station, there is an immense deposit
OF titaniferous iron, running about
so per cen iron and considerable
titanium. At the present time this
ore is improbable, because of being
too refractory on account Of the
titanium content.
The large iron mines OF the Hart.
ville.Sunrise district produce a vast
amount OF ore, but nothing as COM
pared to what a be produced there
II smelted close to the mines. so as to
eliminate the freight charges on the
ore. A great deal of the iron ore Is
shipped because of its principal value
being in some other mineral associate.
During the late val vast tonnage
was shipped from the Deer Creek dis,
trict, along the Converse-Natrona
Fcounty line. because of the high con.
tent of chromium. Ono of the large
iron deposits of central Wyoming Is
on the top of Casper Mountain, just
south from Casper. This r body
ranges through sections 16, IT, 20 and
81. In township SO north, range 70
west. It is about 600 feet wide and

,osure. This bed of iron is sufficient
to supply the world for a great many
years at the present rate Of con
sumption.
Prospecting for copper and asso.
ciated minerals is still going on in the
North Laramie Mountains n Albany
county and in Converse county. Also
In the Copper Mountain district near
Thermopolis, in the Kirwin district
and in the Hartville. Sunrise district.
1.-THE recent discovery of an important
deposit OF native copper near Tie
Siding, Albany county. has brought
renewed interest to the possibilities of
copper mining. There are vast de-
poslts of tungsten here in Wyoming
awaiting development and the open.
ing of this mineral is the matter of
months rather than years.
It is impossible to make an estimate
OF the tonnage Of our iron deposits.
For instance M deposit, in the
Seminole Mountains, at the foot of
Bradley's Peak, about 20 miles north.
east of Rawlins, having available
some 1900, o0o, 900 tons OF high grade
iron. containing very little impurities.
such as phosphorus and sulphur.
This deposit lacks only transportation.
! One subject not to DO overlooked IS
, the immense deposits of ferric oxide,
used in the manufacture OF paints,
One of these deposits has been worked
TO some extent and the ore shipped "a
Salt Lake City. This vein is about
two miles north Of Rawlins.
