I AuOlneT Dig PROJECT again DfluSs
| Grand Junction to the front.
] FOR some months past several cit
liens of this city have had a plan
| quietly under way that promises to
be the best business undertaking ev-
er started here. Ten days ago these
I citizens Incorporated under the laws
/ of Colorado, taking the name of the
| Pyramid Milling & Mining Company,
with a capital stock of S150,O00,
with shares of 81 each.
The incorporators are W. i. DuG-
! ley, James F. Walker, LEROY c. Hedg-
/ es, LDrehzo Hatch, Sr., Ida NJ. lIeds-
es, n. II. Connolly and ". A. CON
nelly.
The field of operation is in the
/ SinDad valley in the southw estern
part OF Mesa county. 75 miles south
west of this city.
The property consists of a group
of fifteen claims. and mill site con-
tanning 100 acres, all carrying a
great deal of high grade copper ore
and a vast amount of low grade ore.
II has been known for years that
the ore deposits of this valley are
of great magnitude and value, yet
the long distance it has been neces-
sary to pack the ore on burros be
fore il could be loaded in wagons for
G0-mile haul to the smelter. has
made mining in this valley, beyond
development work, 10 be practically
prohibitive. To obviate this very
long and expensive haul of crude ma
terial. the Pyramid Milling & Mining
Company will erect on their property
a plant with a capacity of 100 tons
Of ore per day and treat it by what
is known as the teaching process,
which is handled as follows:
BY gravity the ore is brought on
an aerial tram to the mill. passes
into the crusher thence to the rolls.
when it is ground to a fineness which
allows it to pass through a 1O-mesh
screen Ga screen having 100 meshes
to the square inch). From there
the pulp goes into tanks containing
water, when it is treated with a weak
solution of sulphuric acid. which.
when steam is applied. soon washes
or teaches all the copper out of the
pulp. The water and acid carrying
the copper insolution passes into
settling tank where any particles of
sand that have been drawn OFF with
the solution are allowed to settle.
From here the solution goes into
precipitating tank where the copper
in solution is precipitated by the use
of iron. steel or scrap iron.
While this method is a simple one
and has been in operation for sever
al hundred years in Europe and Old
Mexico, and is used today in Aus
tralia, as well as in many parts of
the United States. yet only certain
ores are suitable for teaching. Ores
known as refractory ores cannot be
leached successfully without FIRST
roasting. and this additional cost
makes the smelling of such ores
cheaper. What is known as sand
stone carbonate, practically free from
lime is an ideal ore for teaching
This is theskind of ore the Pyramid
Milling & Mining Company have in
immense quantities.
II is one thing to sink a shaft or
drift through granite. following
narrow fissure vein or cross cutting
through dead rock in the hopes of
striking the vein. or beginning on
the surface and quarrying ore as one
would in a quarry of building stone.
and sending II by a gravity train di-
rect to the mill
Considerable ore from this proper
ty was hauled to Grand Junction and
sold TO the smelter. their ASSAYS run
ming from 6 to 33 per cent copper,
1t is a recognized fact that the best
dividend paying properties in the
world are those having a large de
post of low grade ore. allowing an
immense tonnage to be milled on the
ground ut a low cost. Right here
is where the company is especially
strong, having a vast deposit of ore
IN SIGHT, with plenty of fuel and
lots of good water.
While the difficulty of access to
Sinbad valley has held it back for
many years, no one property owner
feeling able to eXpend the necessary I
amount to build a road, yet the cost
will not be great, and fine road can /.
easily be built having a water grade |
all the way.
The policy of the Pyramid Milling (
& Mining Company is to get the best /
men possible. and to pay good wages .
not how little can they pay for
poor services and to make every
employe stockholder in the proper
~, thus insuring the best results so
far as service is concerned and elm
mating all danger of strikes and la
Dor troubles
The route the company will adopt
for the transportation of its finished
product TO market is not vet decided.
there being two ways feasible One
would be via West creek and the Tn
aweep canon to Grand Junction: the
other following the Dolores river /
down to it's mouth. crossing the
Grand river at that point and con .
Meeting with the Rio Grande rail /
road at Cisco, Utah. The latter route
has the advantage OF cheaper
freight rate and little easier grade.
Many citizens of this town are tax

iasm and the amount of stock al
ready spoken for is surprising. con
