The San Francisco Bulletin Of : re-
cont date contains the following:
CALMALLI, Lower California, Mexico,l
June 20, 1893.
While 20 much IL being said OF the va
rious gold camps in the different parts
Of the world, but little or nothing to
said OF some of those close at home. In
fact, but little has ever been said
through the columns of the press con-
cerning the mines of Calmalli.
The mines Of Calmalli are situated in
the north central portion OF Lower CAL
ifornia, and are midway between the
Gulf Of California and the Pacific ocean.
They lie ll3 deg. 80 min w. and % deg.
16 min. N. being due east Of Cedros
island. in the Pacific, and due west of
Guavmas. Sonora and Menico. and
about 400 miles south Of the Alamo
mines, near Ensenada.
Tie nearest way Of access from or
eQress 70 the mines is at Santa Domingo,
. seaport ON the Pacific, about 40 miles
from Calmalli, BY . good, practical and
and almost level wagon road, beside
many trAils leading to the gulf.
Calmalli's mines were first discovered
In 1882, and in less than year after
ward the section became pretty we'll
known among placer miners. Regard
less of the great scarcity Of water at that
time, many pushed their way to the new
fields only to meet with disappointment.
The reader can imagine the great suffer-
ings and privations those pioneer gold
seekers must have endured. ~ the near
est water was some 20 miles away.
Some years after the discovery Sefior
E. Ybarra prospected here and located
water enough for milling purposes at .
depth Of about 120 feet. The elevation
OF the auriferous slate belt is that of the
low foothill range, which is from 800 to
1880 feet above the sea level. The foot
hill region is all highly metamorphic;
the altered slate strata is far in excess of
the eruptive rock.
The principal quartz veins occupy the
central portion OF the slate belt, and are
not only one, but a series of free gold
bearing quartz veins OF defined charac.
; teristics, which are always distinguished
by the ribbon rock character of quartz.
The slate forms contact with the granite
on the northeast side; near there are
many granite dikes, which follow the
strike and dip of the states, which shows
the age and alienation Of the rock with
some accuracy. With my present knowl-
edge of this region, do not attempt to
classify the rocks into different geologi-
cal periods; however, the relative age Of
some Of the strata is easily determined.
To my knowledge under the owner
ship Of Signor E. Ybarra, the original
locator and owner, 5000 or $500 tons OF
ore were milled, which yielded in the
neighborhood of $100. 900, or ct the rate
of from Sl6 to $40 per ton free gold bull
lion. This includes the ore taken from
the various mines just as 1t was taken
out.
