IN the San Manuel mine, am sat
lshed that | leaned toward con-
servatism, preferring to get samples
/ below the average rather than
above. The result Of Mr.. Prices
essay showed $3.50 gold,and $50. %
silver per ton of ore, altogether$39. :
So per ton.
The mining law of Mexico pro-
vldes that when the dip of the vein
is forty-five degrees and over, the
width OF IA pertinencia or mining
claim shall be increased to two hum
dred metres, which is done in this
case. may here say that all mines
having less. dip than forty-five de-
grees are one hundred metres wide.
The uniform length of all mines are
eight hundred metres, metre be-
ing about thisty-nine and one-third
inches.
GUADALUPENA MINE.
In going up the gorge down
which Copalquin creek flows on the
regular road to Guadalupe Y Calvo,
at the distance of probably three
miles, the gorge bears off eastward
nearly at right angles with its
course below. On the right of this
stream and nearly due north from
Copalquin, and five miles from it, is
the Guadalupena mine. The vein
crops out on the eastern slope of the
mountain, and dips at an angle of
very nearly forty-tive degrees to-
ward the northeast. 1t has been
opened at several places, at an ele-
| walton of / 800 feet above the viii
lage of Copalquin. The ore is very
variable and not SO uniform in quail
ity as that taken from either of the
mines heretofore mentioned. Much
of it is of very low grade, but there
are streaks that are very rich, run
ming several hundreds OF dollars in
! gold and silver to the ton. Some
tree gold is found; generally, how
ever, it is very fine, but / picked up
| some specimens with large eyes Of
| gold. The depth to which the first
! opening has been worked is about
twenty yards. The width of this
vein is six feet; the gangue is
| quartz, and very hard, and the
hanging wall is also quartz, and
shows metal throughout, which
leads me to believe that the full
| thickness of the Wien has not been
| developed.
Several other small openings have
! been made, on the OutcrOp and
good ore taken out, but at no place
has the depth been extended Suili
GENTLY far 10 give any value to re-
port. The vein is broad enough,
and it will doubtless develop into
large paying mine. Ore taken at
several places across the face of the
vein run $2O.29 of gold and sill
yer TO the ton, 1927 of which was
gold. One selected specimen show
ed ST.. 52 in gold and $lS1.91 III sill
yer to the ton or 1929 SO to the ton
in gold and silver.
Constantine MINE.
This lies on the slope of the noun
tain about five hundred feet below
the latter, and cannot with any pro-
priety be called a mine. 1t is sim
ply small opening in vein, spec
linens from which showed only
$l.29 in silver to the ton. The open
ing was filled with water, but the
thickness of the vein is about five
feet. Ii was impossible by reason
of water TO take the specimens from
the full face of the vein.
IIBREs PENsADOREs.
Going up Copalquin creek half Il
mile, and climbing the mountain
on its eastern side TO the crest, and
going to the opposite side, one
stands facing another deep gorge,
down which a small branch, called |
the Reyes, flows. At this point are |
opened the mines called as above. |
The vein is a very fiat one, being |
only twenty-five degrees beyond |
hOriZOntality; the pertinencia there |
fore has a width of 200 metres. The |
mine is 600 feet above the village
1t is opened in several places, but
running down sometimes to mere
threads, and then to seven or eight
feet. The hOrsebacks are formed of
A greasy looking black quartz, while
the vein matter is Il yellowish,
highly decOmpOsed quartz, easy to
take out with the pick only. 1t is
said that the richest ores are al
ways found when the black quartz

Quantities and squeezing it down.
The whole mountain is composed of
;hivered quartz, which makes the
OPP very treacherous. The usual
yield in the Patio process is four
ounces of SILVER and one eighth
ounce of gold to the carga of three
hundred pounds. Rich pockets OF

thousands of dollars are
