The Great Eastern vein and its related structures,
particularly the Siou~ City vein, have been a subject ~f
great interest for many years. Such interest is natural in
light of the strength of the vein and the tenor of the ore
it has intermi tten tly produced • . ' This production has been
w~ested under excruciating conditions of weather, altitude,
and precipitous rock faces.
Also of great and long ... standi!l·g interest is the poss'i
bility of crosscutti!lg .the Great Eastern vein at a substantial
d~pth below its outcrop • . The,p6ssibility of executing such
a pr~~ram is excellent through joint use of the Silver Wi~g
Tunnel wherein more than half 9f .the necessary work has
already been done. This crosscut, portaled at an. elevation
of 10, 400. f~et, would, ,if proj ected, intersect the Great' Easte:n
vein almost 2,000 ~ertical feet below its h~ghest outcrop and
about , 1~500 feet below th~ current upper worki!lgs.
The purpose of this report is to evaluate whether the
interveni!lg 1,500 feet constitute a , geol~gic target worthy of
invest~gation and, if so, what the details of an exploration
pr~gram would be. It does indeed appear that the downward
projection of the Great Eastern vein and its related structures
comprise a ta!get worthy of exploration, and that such explora:io~
can be £easibly conducted thro~gh the Silver Wing. Tunnel. The
reasons therefor and the details incident thereto are herein-
after -set forth.

CONCLUSIONS:
I. The geologic structure, the perpetuation of this
structure, and the tenor of mineralization within the Great
Eastern vein are such that it is considered an outstandi?g
, . geologic target for furth~r exploration and developmerit at
depth;
II,. The for~goi~g premise is enhanced by th~ fact that
there is a projected intersection at depth with the strong,
tho~gh lesser, ,Sioux City vein which is also well mineraliz~d;
III. This premise is still further enhanced by a projecteE
intersection of the steeplyMdtppi~g , and cros's-striking Carol
vein;
IV. The intersection of these structures would comprise , '
a locus of great shattering which, in knQ;.o.rn mineralized v'eins,
would normally localize mineral deposition to f6rm a h~gh.
, gr~de ore . body;
V • The direct explbi'ation of this area '· can be conducted
. with reas~nable expenditures of time and money ~hrough joint
use pf the Silver Wing Tunnel:
(1) This would permit an all-weather pr~gram;
,(2) Any subsequent operation of the Great Eastern or associated veins at this depth could be conducted through the Silver Wing Tunnel as extend~d; ' .
(3) .The projected exploration and possible operatio!:. can be extended to include the Monitor and Klondike veins. It is pointed out that these veins are not a part of ' the Great Eastern Mines, Inc. and their acquisition would be a matter of future negotiation.

'4) Inasmuch as the Silver Wing Tunnel is -a "gunbarrel" crosscut and the proposed pro .. jection would be a straightline continuation thereof, any future heavy haulage could be effected with an underground conveyor belt for waste and ore. Thus only a single track would be required for a mart tram and supply •
.. (5) - From adequate drill stations underground it
would be feasible to conduct down~dip drilling on the Great Eastern vein and related stru~- tures and to probe the underlying sediments (limestones) to basement. -
FINAL CONCLUSION: Notwithstandi~g the attractiveness
- of the projected geol~gic targets, the proposed exploration
should be undertaken only by an organization that is adequately
financed and properly staffed ,for matters mini~g~ This would
include operati~g'mini~g companies -desirous of expanding the
scope of their operations or an eminently able individual or
group of private investors who are desirous of conducting
such .an exploration within . the writeoff provisions of existi~g
tax laws. It is, emphatically not an undertaking for out-of ..
pocket, savings accounts, of parsimonious promotion.

GEOLOGY':
The Great Eastern vein occupies a large fissure (25 or
more feet w~de) within the Eureka Rhyolite (upper) and Picayune
andesite (lower) on the eastern edge of the Silverton caldera.
These two formations are lower members of the Silverton volcanic
series. The large and well-defined fissures such as the one
co.ntaining the Great Eastern vein are members of a "ring fault"
system associated with the collapse of the Silverton caldera •.
In the vicinity of the Great Eastern they trend northeast
southwest an~ the dip is steeply westward. The smaller faults
trending across these major s~ructures ·(such as the Sioux City
and ' Carol fissures) are relief or readjustment features. The
dip of these smaller fissures is generally near-vertical. It
appears th~t all of the northerly-trendi?g fissures within
the Great Eastern Group will terminate to the north against
the Fredrica shear, while to the south and southwest they
proj ect ·into the Animas gorge. ' . I····
The mast attractive aspects of the Great Eastern exploration
lie in (1) a projected intersection of the Great Eastern,
Sioux City, and Carol veins at an elevation approximati?g
that of .the Silver Wing Tunnel, and .(2) the feasibility of
exploring this target by drivi!lg that Tunnel straight ahead.
Plate IV shows thi~ ; Telationship in cross section while Plate III
shows that the veins converge along strike also. The locus
of their intersection will rake steeply to the north and the
. projected crosscut will approximately intersect their juncture.
What influence the smaller and vertical Ii-dipping Carol structure
will exert is a matter of conjecture, but the overall evaluation .~~ o -)~
of this situation indicates an area of great shattering with
a high percent~ge of ~rimary ?penings which could serve as
a locus for the deposition of ore minerals. As such it
constitutes an outstanding geologic target worthy of the
exploration and development work outlined herein.
While it is impossible to make specific projections
regarding tenor, it is noteworthy that the Great Eastern vein
has produced some excellent ore from near-surface workings •
. The character of this ore is shown ~n the shipping returns
attached hereto. Similar ore remains in place, and a summer
operation thereon is contempl~ted for the near future.
Associated with this higher. grade material is a much larger
quantity of low grade which has been bypassed and left in
place, or dumped.
The charac·ter of this mineralization is observed to ·
project downward from the. highest workings, and between
surface and underground e~posures at lease 500 vertical feet
of mineralized vein is shown. How muchfu·rther downward it
projects :is strictly a matter of conjecture, for exploration
al.one w~ll reveal this ul timate d~pth. -It is this author's
carefully considered op~nion that th~ favorable aspects of
the structure increase with depth and, therefore, it may
be .reasonably expected that the 'quality of the vein will
increase also, whether in tonnage, tenor, or both.
An · unknown factor will be the possible change in para
genesis when the vein passes from the overlying Eureka
rhyolite into the Picayune andesite. This relationship is
shown in Plate IV. The raising which has been prescribed ( .,
herein is for the purpose of exploring the contact between
the two lavas.

LOCATION AND ACCESS:
The properties of the Great Eastern Mines, Inc. are
situate as shown on Plates I, ,-.II, and IlIon the northwest
spur of Jones Mountain. Plate II shows an apparent dis
crepancy wherein the names of Jones Mountain and Niagra
Peak have been reversed. Also there is a di~crepancy in the
designation of "Picayne Gulch" which should read "Picay~ne
Gulch". It is here that the Picayune andesite is well shown
t~gether with its relationship to the overlying Euieka
rhyolite.
The properties are accessible via the roads shown on
Plates I and II. The distance from the 'portal of the Silver
Wing Tunnel to Silve.rton is just over 11 miles. The approxi
mate distance to the upper workings is about 14 miles, and
these are accessible only during the summer months. The
two means of access which must be considered are (1) via the
aforementioned roads duri!lg the summer months only and . . . ;:
(2) Vla an extenslonof the Silver Wi!lg Tunnel to crosscUt
the projected structures at depth.
Inasmuch as the portal of the Silver Wing Tunnel is
: gener...ally accessible thro~ghout the year, the exploration
pr~gram herein outlirtes proposes to take advantage of the
convenience and relati~e c~mfort of a direct approach from
underground. Nothing herein would impede or impair the
conduct of near-surface workings on the high grade showirigs
within the Great Eastern vein during the summer months.
