MINING DISTRICT
The Important Development Work
That Has Been Done During the
Year 1907.

he developments In tue mag
dalena mining district in Socor-
no county during the year 1907
were of more importance than in
any five years of its previous his
tory, Notwithstanding the fact
that the tonnage shipped was
smaller than in 1906.
The Graphic, Tri-Bullion.
Mine Development, Misletoe,
Capital and Germany companies
confined their principal opera
tious to development work.
The Graphic Company has
pushed an extensive system of
development during the year,
exposing ore on the seventh,
eighth and ninth levels the lat
ter being the lowest workings in
the mine.
The levels are connected By
several raises with the sixth lev
ell, which was the deepest work
ings before the Waldo tunnel
(ninth level) was run.
The ore shoot is about 400
feet long, which has been cross
cut several times on each level;
one croSS-cut on the ninth level
shows los feet of ore, horizon
tally across the ore body, the
dip of the strata being about As
degrees. The ore is principally
zinc sulphide, occasionally merg-
ing into zinc-lead sulphide,
which requires some mechanical
separation. A portion of the
zinc sulphide contains as high as
40 per cent metallic zinc; the
greater portion, however, is low-
er in grade and will require con-
centration.
The company has been expert
menting on several milling pro-
cesses, and it is generally under
stood that they will soon install
a concentrating plant. There is
abundant water in the mine for
milling purposes.
The Tri-Bullion company is
con6ning its development to the
Nit shift. They have large
tonnage of both sulphide and
carbonate ore (zinc) in the Kelly
mine. They have just installed
250-ton concentrating plant.
The Mine Development COM
pany commenced shipping oxi-
died lead ore in September, af-
ter connecting the Tip Top and
Key mines with the tunnel that
starts on the west side of the
mountains, known as the Tip
Top Tunnel" The output was
about Is cars per month until
the decline in the price of lead
on the first of December, making
it necessary to suspend shipments
from the Key and Tip Top mines
until the price of metal advances
to a normal basis.
In the meantime, the company
is pushing development for the
economic operation of the several
mines along the line of the Tip
Top Tunnel, which work was
necessarily DELAYED on account
of ventilation until the mines
were connected.
The workings are all being
driven in oxidized lead ore
which contains about 81 gold
per ton. The amount of gold
has been increasing during the
past month.
The Stonewall, a property oi
the Mine Development company
operated under lease by William
Martin, has been. shipping car
Donate of lead ore similar to the
ore shipped by the company
from the Key and Tip Top mines
but running higher in gold, tn,
average of the last five cars ship
ped being eight-tenths of al
ounce of gold per ton.
Considerable work has beel
done on the South Juanita dur
ing the year.
A large force of men under tn
management of William f. Cor
don was employed on the Misle
toe Group the most of the year
A large body of zinc lead sui
phide was developed.
Hill Brothers, owners of tn
Capital Group, are driving tun
mel (day and night shifts) to GU
a shoot of ore developed by
shaft above.
The Germany company
working the largest force in tn
camp, developing the Alhambr
and Germany mines, both by tur
nels, which will be extended I
develop and operate propertie
lying east and above the Alhan
bra and Germany mines.
Both tunnels are cross-cuttin
