sioe OF secret canyon lies tue famous
Page and Corwin mine. now the prop
erty Of Phil Paroni aud James Murray.
from which a large quantity Of valuable
ore has been taken. This property has
been worked by leasers since the fret Of
last January. and is now being worked
by John and Ben Repetto and three
associates. A shipment Of ore was made
from this mine early in the Summer
which averaged s5s in gold per ton.
according to the smelter returns. and
there Is now on the dump another ship
ment Of about 80 tons which will prob
ably yield q larger sum. This mine now
has what appears to be q very good ore
body in sight. and is in excellent shape for
further production. The shaft is down
about 200 feet. All Of the work has
been well done, so the mine is ready at
any time for extensive operations.
On the opposit, side Of Secret Canyon
from these mines lie several Of the IA
nous producers Of the early days. The
Geddes- Bertrand, Irish Ambassador,
Baysee. Wolverine, Burning Moscow
and other well-known properties on
that side of the Canyon are either al
ready bonded or are being considered by
mining men. The old workings are ex-
tensive. and it Is presumed that q com-
paratively small amount of develop.
ment work will be required to again
bring this once productive region into
prominence as an immessSly profitable
producer of high grade ores.
New Mines An Gold Pr0dseers
The new mines are all gold producers
and. from the standpoint of geology.
and the experience Of the past 40 years
in Eureka district, they are located in q
section of country which merits un-
bounded confidence.
In Eureka district, allthe mineralized
formations lie on the west side Of the
Eureka quartzite, which can be traced
in a north south direction for a distance
Of 400 miles. To the west of the quartz
lite. and lying somewhat upon 1t about
1000 feet is the Pogonip lime. In the
Adams Hill region. which has been ex.
plored to some extent, this lime carries
rich deposits of silver and lead. The
dip Of all the formations on the lime OF
this section is from 20 TO 30 degrees to
the east. Under the Pogonip lime lies
a belt of Hamburg shale about 300 feet
in thickness. Following this shale is
the Hamburg lime. which is the gold
bearing formation in the whole district.

lie in this belt. On the line of this sec.
ton Of the district the Hamburg lime
is about 5000 feet in thickness. The
Hamburg lime extends from Adams
Hill on the north. southwark for q dis
lance Of about Is miles, aud disappears
in Fish Greek valley. = This formation
has not been explored to any great
depth. there being but one shaft. that
of the Hamburg mine sunk lower than
500 feet.
The Hamburg lime on the surface
usually has a blush color. which
weathers 10 a blush gray dust. 1t ap-
pears as c~alcite. coarse marble, hard
white and blue limestone. and in the
neighborhood of ore bodies it is usually
stained from = light yellow to a deep
reddish brown by oxides of iron. NJ
merous caves and vuggs occur in it. and
everywhere the effect of the action of
water may be seen. Breccia Of differ
emit kinds of limestone and quartz are
frequently encountered, and the brecci.
ated quartz invariably carries goli val.
ues. The oxide ore from the Windfall
mine Is Of a peculiar nature. 1t is very
soft, and is so fine that over 90 per cent
of it will pass through a 6O-mesh sieve
as it comes from the mine. The ship
ments made from this mine were ex-
tracted with pick and shovel. No pow
der is used in mining this ore. Only
Al sticks of powder have been used in
the Windfall.
Prospsctors Busy In This District

trict. We regret that time and space will
not now permit US to 20 further in the
description of a dozen or q score more of
the new mining properties that have
been undergoing development during
the past year or two. While the outside
world seems to have been resting, the
prospectors have been exceedingly busy
in this region. AS Q result there are
now a large number of claims and
groups of claims which have had
sufficient work done on them to show
up true values. and the, mining men
who are daily coming into this district
are frequently expressing their at ,nish.
ment at the unusually large number Of
good properties on which the develop
