eroy did he the honor to adept my coz.
nofnan as the name Of the shatt.
BY reason of Los PlanchaS hdviug
according 10 both history and tradition,
figured over century ago as one of the
| richest and most productive mining dis
| tricts ID Mexico, the public must feel
some interest in the first earnest effort
ever made to restore its long lost bril-
liant record, hence | submit for public
alton the folio wing notes dictated by
! Col. PoMeroy, which will SLOW what
has been accomplished since my July re-
port on this property. Late work on
| the Mexia mine was done TO connect the
tunnel level with the surface by an up
raise on an incline for ventilation, AMI
| also TO sink a shaft 40 IT. below the
level. thereby attaining depth OF 2UO
! Il. from the surface. The work shows
u we'll defined vein (about 30 degreesl
| betaeen porphyry and conglomerate,
/ winch by some would be called con-
tact ledge. Ore is found from the sur
face 10 the bottom Of the shaft. Rock
containing mineral along the tunnel
level for distance of 100 it., and also
| from places in cross cuts 40 ft. apart
surveyed without asserting IL OF. in
silver. The crevice for distance of 40
fit. wide assays from 10 10 ID o., which
is an excellent cohcen tTating proposition,
as the gang is light and easily separated
from the metal.
Finding mineral on what appeared to
be the hanging wall Of the Hilo mire q
cross. cut was run 30 fl. into the noun
tain, showing what appeared to be an
other vein with its hanging, and foot
walls and crevice matter, tive It. wide,
sssayiug we'll. The ore is now coming
in solid. This discovery was equivalent
to that OF finding 4 new mine Of good
shipping and milling ore. Another
cross cut is now beng run below on the
third level.
The work for years past on the Ledero
mine was done on the surface, making
huge open cut, the ground plan OF
which is IN the shape OF horse
shoe and $50 feet in diameter, with
greatest depth 30 feet. After much
prospecting OF these cd workings Col.
Pomeroy found a foot wall running
through the work. clearly defined on
tho bottom ard on both sides. The
y ork showed that there was a blow
OUT OF ore running down the hill from
the horseshoe" The principal exca-
waiting was done above the wall, from
which large quantities of fine ore had
been taken. A tunnel was started last
December 10 get under the old work
in g. and il has now reached reddish
brown rock, similar to that of the hang,
ing wall shown in the old works The
colonel estimates that within 30 feet
more the tunnel will penetrate the reef,
and reach the foot wall at depth of
about 40 feet. The large cut shows
ore IN various places, as do other small
shafts and openings to the summit OF
the mountains, distance OF 30 feet.
The finding of the foot wall demon
strates that the LedeTo is an immense
fissure vein, ana that the tunnel now
being rapidly pushed ahead will en-
counter large bodies OF ore.
During my stay at Nogales formed
the acquaintance OF Arthur l.. Turney
young Eenglishman, who is engaged
ia the development of the Winnie mine,
formerly called the San Eufracio, To-
Gated on the headwaters Of the Sonora
river, Arispe district, 125 miles south
east Of Nogales. He came into possess
oiOu VI NHlS
ago, since which he has been assidu
ously engaged in opening up the same,
employing about % men constantly. The
present developments, he says, are 2UO
foot shaft and two tunnels, one 100 feet
and the otter 40 feet. He has en-
countered a ledge of from ~ to B feet
wide, from to inches OF which gives
an average assay Of $50 ounces Of silver.
His purpose is to ascertain the extent or
the lead, and erect a suitable plant to
treat the ores or the ground.
Traditions of fabulous wealth are
related concerning this mine, which
may be regarded as an ample excuse
for reference to it, even were there no
assurances of its eventually proving one
Of the most valuable properties In the
district. Maps Of the district design
ing this mine may be seen dating back
to the year 1892 at which time, as the
legend goes, IL Was noted for the guam
titles OF rich ore extracted from it by
the Mexicans. and for a tragic event
which terminated the lives Of a number
&c the miners employed IN the mine.
Little attention was at first paid to these
stories by Mr.. Turney until sometime af
ter work began, when in prospecting the
old shaft, bones Of human beings were
discovered at the bottom, depth of
nearly 200 feet, and also numerous
pieces of native silver, more credit has
since been placed upon what the natives
iterate and reiterate as facts. It's claim
ed that the miners were murdered by
Indians and .some burned up, and the
owners were compelled to conceal the
inc and abandon it, expecting to re
turn when the Indian troubles should
end. Every sign goes to confirm the
belief that there is much truth in the
tradition above cited. Even old dumps
and Stag piles, by the large mesquite
trees growing upon them prove the an
cientness OF this end other mining oper
ations in the district.
