ALBUQUERQUE, N M.-An the
geological signs, in the opinion of min
ing men who know, point to the pres
| ence of great bodies of rich copper ore
| at considerable depth in the mining
! fields of the Sandia and Manzano
mountains east of this city. The nu-
merous mining outfits now pushing
development of various properties IN
the field tributary to Albuquerque have
all demonstrated the fact that the
hills are richly mineralized, and the
deeper they go the better the ore and
the more promising the indications.
The formation in the Soda Springs
district consists of a lime rock cap
ping, lying horizontally, varying from
O few feet to over 500 feet in thick
ness This lime rock overlies stratum
of granite which runs from few feet
to 300 feet in thickness and stands
tilted at various angles. Under all
this lies the lower schist formation.
This is tilted bearing in an easterly
and westerly to northeasterly and
southwesterly direction and pitching
some so to rs feet a hundred from the
perpendicular as it cut down into the
earth.
Development in this district shows
the vein matter in the lime rock and
granite to consist principally of a spar
galena ore bearing silver and lead.
There are several of these veins now
being developed which show high val
ues. Among these are the SWastlka,
Bear Group, Octoroon and Ruppe prop
critics. The schist formation carries
several quartz veins and schist dikes
which bear in an easterly and westerly
direction. These veins do not extend
UP into the granite and lime forma'
ton.
ALYARADO ACTIVE
The principal work being done in this
formation is by the Alvarado Mining
company and William Chaplin. the
AlVarado company has very valuable
holdings of gold and silver and the
Chaplin properties show rich bodies of
gold and silver and copper, as far as
developed.
There are numerous other workings
in this district which show very fine
prospects in consideration of the work
DONE The Octoroon company recently
shipped from Albuquerque another car
load of ore and has a good sized force
of men taking out the stuff all the
time.
The northerly ead of the He'll Can
Won district extends into the lime and
granite formations, joining the Soda
Springs district at the top of the DIVIDE.
The veins and mineral here are the
same as III the upper formation of the
Soda Springs district The chief part
of this district includes North Canyon
and the mouth of He'll canyon proper
and the adjacent district extending
south. The formation in North cam
yon and the mouth of Hell canyon Is
of schrist, an extension of the lower
formation of the Soda Springs field,
and the pitch and course of the schist
atipo 11Ny thp consist
ing of quartz, spar, schist and por-
phyry. The quartz and porphyry veins
bear with the country rock, While the
spar and schist dil1es crosscut the
country, cutting through the quartz
and porphyry veins as we'll as the
country rock. These cross-country
veins are true assures of great length
and they extend far down into the
earth. From He'll canyon south the
lowest visible formation is of dlorlte
with a lime rock Gaping. The diorite
lies tilted and carries several quartz
veins.
The properties of the Providence
Copper Mining company, f. H. Kent,
and the Mckinney group are located
in this portion of the district. All of
these properties have proved valuable
deposits of gold and silver in their
upper workings, while at greater depth
in all cases the mineral has turned to
copper.
GREY EAGLE NINE
The Grey Eagle mine in the mouth
of He'll canyon and the Pittsburg mine
in North canyon, which We're each SUNK
to a depth of about so feet some years
ago, together with numerous shallow
prospects sunk at that time, eacn
showed fine values in gold, silver and
copper for their depth.
Some 400 acres of the mouth of Hell
canyon and practically all of the basin
of North canyon are now owned by
the Sunset Mining and Smelling COM
pany, which has been doing extensive
prospect and development work on the
quartz and porphyry, as we'll as the
cross country veins, for the past two
years.
They have proved that q great num-
ber of the veins bearing with the schist
carry good values of gold, silver, cop
per and lead. The highest values in
these veins are found at the intersec-
ton with the quartz-porphyry veins.
The Nonesuch mine of the company,
on a schist vein, will not only develop
the cross country vein, but will cut
and enable the company to work all
rich quartz and porphyry veins out
cropping nearby, If development is car
ried far enough.
The Venus mine of this company is
Oll d Spdl NG4Il5 lilC ocbAiAS hOAAA S'0 49,
Swastika and Bear groups, except that
this mine has reached the schrist or
lower formation. From the grass roots
down it bears a good percentage of lead
and from the fact that it bears cross
country, the future development of this
mine will work the quartz veins.
The old Pittsburg mine is now owned
by this company, but is not being
worked, as the workings from both
the Venus and the Nonesuch mines will
cut the same vein at great depth. At
so feet deep this mine shows an aver
age of SIS a ton, with pockets running
as high as $25 ton.
The existence of veins running cross
country for great distances is a con-
dition peculiar to but few of the known
mineraliZed districts 1t affords the
possibility of prospecting and working
a great number of veins with one shaft.
Moreover, such a condition is a strong
indication of much high grade ore.
Geologically, when two veins inter-
sect one or both veins are richer in
the vicinity of the intersection than in
the rest of the vein. 1t is believed
that reasonable development will show
this district to be one of the best in
the southwest 1t is the general be-
lief that the entire field is underlaid
with great body Of copper, and there
is every reason to expect the develop
ment of very valuable mines in the
Sandals and Manzanos.
