dive, The property has been opened
by two shafts one am nclIne sunk to

10 improve the incline by sinking II
an additional 100 feet and making IL
double compartment. Water has been
encountered I'm the wines sunk below
the 400, indicating that the water level
has been reached and that the desired
change in the character Of the ore Is
about TO take place. A new steam
hoist viii probably Doe installed during
the next year.
O. r. GEOLOGICAL CONDITIONS,
The geological conditions Of the O.
Is are sized up By Mr., Gates IN the
following.
"On the furfaCe q strong, well defined
east and west cropping stands out, be-
ing 60 feet wide at the point where the
uClinc shaft was sunk, widening TO
900 feet opposite the main shaft. This
cropping shows heavy copper carbon
ate stains and even sulphldes scattered
throughout The vein Is prominent In
It's groupings for 500 feet along It's
course showing the same mlnerli1a-
tlon. and dips 90 degrees to the north.
The walls are both of a compact gran
ltc and I'm the vicinity Of the vein are
minewlizad with finely disseminated
sulphIdcs, not being Of commercial
value but simply showing evidences OF
strong naturalization. lntersecting this
main vein are four cross assures rum
ming north and south. At the lntersec-
lions Of two Of these cross assures
with the main vein, large shoots or
ore have been encountered and, as
these were the smallest ! have ever
reason 20 believe that when the two
westerly and stronger veins are en-
countered, larger Shoots" will be
opened up. The ore is slliceous carry
ing the values In carbonates and oxides

ulphides Of chalcopyrites and bornite

OLD HICKORY MINE.
What the old Hickory mine will de-
yelop into can only be conjectured, but
that II win grow into great propor-
lions there Is not the slightest room
tor doubt, unless an the rules ofgeolOgy
are completely upset. The Old Hickory
contains some immense copper crop
pings; the ore Is heavily impregnated
with iron and Is ideal for fuxing pur-
poses; the veins are large and, with
depth, no doubt some very rich ore

The main shaft Is down TO what Is
known as the fourth level, this shaft Is
now being sunk 100 feet deeper and Nu-
merous winzeaare being sunk IN ore
one Is being sunk from the fourth level
and win reach the 500 simultaneous
with the shaft, when connections be-
tween the two viii be made.

There are two large north and south
veins exposed TO the east and west con-
facts of a large lime belt which has
broken through the porphyry dipping

the groupings are 80 feet across. Wild
