MEXICAN MINE IS
MAKING BIG PROFIT
FL Monte San Nicolas Has but
Small Operating Ex-
penSeS.

There are many mines in Mexico that
| are producing large amounts of the
precious metal, resulting in good prof.
| its TO their owners, OF which tho gen
eral public have very little knowledge
One of these mines is the FL Monte
San Nicolas mine in the GuanaJnato
district, says tho Wall Street Summary.
This property is situated about four
miles northeast OF Guanajuato on the
FL Monte Pcregrino vein system, and
has been extracting rich ore from the
particular part of the mine known as
the San Juan vein, which is a hanging
wall vein to the main lode of the prop
erty, dipping Mt an angle of 40 degrees
to the west. Since a crosscut from the
main vein workings on the 2OO-meter
level encountered the San Juan VEN
some two and half years ago, which
vein the miners have been trying 10
find for years and which had been
worked by the lessees of the El Monte
property, was known to be IN the hang
ing wall TO the main vein, and to have
been in bonanza and so left by them.
The working Of it from the main VEN
workings was covered and filed with
caving and waste so that it was impos-
slble for the owners TO locate the San
Juan adits, therefore it was necessary
to drive new workings 10 encounter this
old vein. IL is claimed by old miners
who worked on the property that the
workings spoken of were filled and OBJ
liberated at the time the lessees gave
the mine up to its owners because they
were unable to renew IL, which produc-
tion of the same vein would now lndi-
cate.
Cuts Old Shaft.
Some two and n half years ago, as
before stated, n crosscut was driven
nearly seventy meters to the west from
the 200-meter level and an old shaft was
cut INTO, when the crosscut encountered
the San Juan vein, and for some time,
in fact till about a year ago, the prop
erty was worked very slowly. The
property was finally offered for sale,
this vein, and no one knew what 1t
was, or whether it was but bunch of
rich ore that had been encountered,
there was no buyer at the price asked.
However, the San Juan vein alone dur
ing the last year has produced more
money than the price that had been
asked for the property. 1T is claimed
that where the present production is
coming from, the San Juan vein is over
seven feet wide. Five feet of the width
of the vein ships Approximately 500
per ton, and the remaining two feet
of the Vein averages $4,000 per ton,
the greater portion Of the values being
in gold
1t is claimed that old records of the
ore shipped by the lessees show ship
ments Of ore going as high as $4,000
per ton, from the San Juan vein and
show that there is a deep shaft on that
vein connected with other workings of
the mine, and extend some distance be.
low the present known workings. This
shaft had masonry steps going down
into it which have been enc ountered on
the San Juan vein and in all probabil-
lty another shaft on the same vein for
1t has none of the masonry steps or
other indications.
In sinking on the vein in present
workings the ore has been getting
steadily richer as depth has been at,
tanned, and the production of the mine
has steadily crept up, until now they
are producing approximately $4,000
monthly. with total expense of only
$24o0. This large production with so
small an expense shows clearly that the
grade OF ore mnst be very high.
