Considering the attention that Is at
present directed to Mexico. the following
communication will bs perused with in.
tercst by our readers:
EprroE News: Having spent several
years in the various mines Of Mexico. at
lsast in the northern part Of Il. compri.
sing the States Of Nusvo Leon, Chi.
huahus. San Luis Potosi. Zscatecas. Du-
range and Sinaloa, I will endeavor to
give you some idea Of the formation OF
veins and the different classes OF ores
extracted from them. the mode OF opera
ting mines and the manner OF milling
employed in the haciendas or reduction
works.
The veins can generally be traced on
the surface. not by large rough crop
pings. but by a clearly visible formation
Of carbonate OF lime. oxide Of iron. aud
iron ochre. often intermixcd with green
carbonate OF copper. and distinguishes
bio all the more as they are generally
found In bedrock OF blue or dark brown
slate. Most Of these veins are, from the
surface down. possessed OF such n won
derfully true underlay. that a tunnel to
them can be calculated within q few feet
to n certainty.
Nature Of the Ores.
On the eastern slopo OF the Sierra
Maars' ana through u 'ne su"' al
vsr'bsaring veins carry down to a certain
depth q variety Of ores. some OF which
are found in no other part Of tho world.
Tho most prominent are lodite and
Bromargyrits. or lode aud bronze silver.
Both species are called "p!ata VERDE"
or green silver. and are found In scales
or small crystals on carbonate OF lime OF
tho afore-mads description OF groupings.
This matter extends. in the District OF
Catoru, for example, down to u depth OF
