Letter from Poorman's District.
PooRMAN's MINING DISTRICT,
October 4th, 1881.


Mine in this camp has been owned by
citizens Of Yuma for five years or more,
yet 1 presume that very few persons
could tell where it is situated, and much
less do they know of the char acter of the
mine itself, except that, as they suppose,
1t is a lead mine. I will take much
pleasure in posting the public generally
as to the merits of this much sighted yet
really valuable property, which, coming
as it does from an entirely disinterested
party. will surely have some weight.
In the first place, it is situated about IS
miles directly Forth OF Yuma, about Is
miles northeast from Mesquite station,
on the s. 2. r. R. and eight miles south
OF the San Bernardino and Ehrenberg
wagon road. The Colorado River is in
full view from the mine, fifteen miles dis
tant, to which there is a ost excellent
wagon DAD over the mesa, with q grade
OF one hundred feet to the mile down to
the landing. The mine Is located about
five miles east OF the base of the Mesquite
mountains, in some low foothills, none Of
which are over one hundred feet high.
One half OF the claim lies in the wash or
arroyo, and the other half on the mesa.
and is all perfectly level except where the
ledge matter itself rises boldly out of the
ground, some places as high as fifteen
feet. The ledge appears to be here all Of
twenty five feet wide, although there
have been no cross-cuts to determine the
width exactly. There is one incline sunk
in the wash to the depth Of fifty feet, and
appears to be in about the center OF the
ledge. It was started on a seam Of gale
ma some eight inches thick, and carries
this streak from top to bottom. Further
west, at about the center of the claim, is
a vertical shaft some sixteen feet deep.
This was started on another seam OF
metal and is entirely IN ledge matter with
no walls. Two me are now engaged In
sinking on this shaft. Still further west
are two shafts side by side, down ten feet
Oh seams of carbonate and galena. This
is all the work done on the mine. For
the time and money expended upon 1t, it
is very poor showing. The ledge mat
ter comprises calc spar, flour spar, white
carbonate. galena, silver glance and
quartz. Strange to say the only thing
which was considered valuable was the
galena, while a much better quality of
silver quartz can be gathered from the
surface groupings.
This mine has the advantage OF being
in low solid formation, particularly
well defined contact vein, being between
GRANTEES and porphyry, and having bold
quartz Groupings from one end monument
to the other. So far as 1t has been pros
pected it has improved as ledge of mill
ing ore, and few hundred dollars judi
eiously expended would no doubt make it
paying concern. There is 4 most ex
cellent chance for vertical shaft to tap
ledge anywhere from two to five hundred
feet, and until some such step is inaug-
urated tbs mine will continue to occupy
q back seat.
This being che first location on the
ledge, the lodge is naturally known as the
Luz ledge. There have recently been
several extensions each way from the Lug
by other parties. The same bold out
crop continues for one and a half miles,
and three thoesand feet west of the Luz
a shaft hrs been sunk on the granite foot
wall to the depth of ninety feet, the entire
shaft from top to bottom being in quartz
aud galsna, several tons OF which are now
on the dump. 1t is intended to push this
shaft to the 200 feet level at once
This camp has recently been re-organ.

than for some time past. Hoping TO
keep your readers posted with regard TO
the work on the different mines, l remain
