OBSERVATION-DISCLOSURES

The Eagle Mountain mining region
lies in Riverside county about forty to
fifty miles northeast of Walters station
on the Southern Pacific railroad. 1t a
mountain all by itself except on the
southwest, where a spur joins the Cot
tonwood range, but it does not belong
| to that range geographically, mineral
| logically or in any other respect.
For the geologist, mineralogist and the
mining man there is no part Of the desert
| more interesting as study The area
embraced in the district may be roughly
estimated at about fifteen by twenty
| miles, the mineral belt being several
miles in width and extending in length
from Virginia Dale and Pinto mountain
on the north to the Chuckawallas on the
south. In what is known as Eagle
mountain proper can be seen many evil
dences of volcanic action and the gen.
eral opinion of those who have given this
region study is that at some remote
period the entire mountain was burn
ing volcano. On all sides the mountains
rise up to a height of probably 1900 to
1000 feet above the surrounding valleys,
while in the center there is a very notice
able depression. Within this depression
or crater-like amphitheater, and extend
ing on all sides beyond it, are many evil
| dences of ore bodies and a general min
eralization of the entire country. The
different contacts are distinctly marked
and traceable for miles and the lodges
can be traced on the surface in most in
stances a great distance. Here almost
every known combination of contac cts
can be found and these contacts are so
| distinctly marked that they indicate
both theoretically and practically the
very best condolences for the forma-
| ton of vens and ore bodies and general
| naturalization as is recognized by all
| students of ore and ledge phenomena.
| On the northwest for several miles lies
a low range of diorite, commonly known
as malipy, which represents the closing
scene of a great volcanic disturbance.
| With the exception of this diorite or
volcanic lava, throughout the entire
mountain from a theoretical geological
| point of view no region of the state could
| be considered more favorable for the
production of veins of mineral bearing
ore. There are a great many large mag
| netic and hematite iron Lodges that ex-
| tend for miles through the mountain.
| Paralleling these iron veins runs the
| blue and yellow limestone with large in
| truded masses of quartzite and por-
phyry dykes. In the southern part of
the mountain the contact is granite and
mica schist with an occasional contact
| of quartzite and tracite. Such forma
| lions the world over are notorious for
its collaborating tendencies and Eagle
mountain is no exception. Wherever
any of these contacts are encountered
there are evidences of an unusual num-
Der of viens within a comparatively small
area, not a few of which have been pros
pected and so far as developed proved to
be true tissues. Most of the develop
ment work yet done has for the most
part been on shipping ore though re-
ports are encouraging on every ledge
so far sunk on s,s--.--
At present the Iron Chief is the most
promising claim in the district. Not
| that it shows up any better on the sur
face than many of the others, but be-
cause more work has been done here
than on any other claim. There are two
shafts on the property about eighty feet
deep connected by level 100 feet in
length. The mine has been an inces-
| SAINT producer since its discovery in the
spring of 1896 Several carloads of ore
have been shipped, sampling on an av-
erage of $50 per ton, though 1t is under
stood the last carload went $115 per ton.
Besides the shipping ore they have on
the dump over 200 tons of cyaniding ore
that will run $25 per ton. The character
| of the ore is hematite iron containing
| lime and porphyry. The contact is lime
and granite. 1t is authoritatively stat
! ed that crusher of ten tons capacity
with cyanide plant attached will be at
work on the mine in less than sixty days,
though a letter just from that district
| says the plant will be al work by Aug
ust 10.
The mine is owned by San Bernardino
and Los Angeles parties. ]. S. Beach of
Los Angeles is superintendent,
Another promising mine is the Cactus,
only a mile or so from Iron Chief, and
owned by the Eagle Mountain Gold
| Mining company, composed of Los Ange-
les and Riverside men. Henry Coon of
Riverside is superintendent
The ore is rose quartz in porphyry
and quartzite contact. The shaft is
100 feet deep, besides some drifting, al!
of which is in good milling ore. AT pres
ent, they have shut down for the hot
weather, but intend to put in new
hoist, and be at work by September lst
In this immediate vicinity are number
of promising prospects. e Among those
who own promising locations may be
noted Frank Baxter, William Blair,
Burt and Carlson, Fred L. Luce and
William McGuiness. ]. H. Bergman, c.
