t'on, which resulted in finding great
houlders of quartz which had rolIsd
gown the mountain side, containing
iustrous metal. After careful invaso
tlgatlon it was found to contain horn
silver and sulphide of silver. With
TINS clue to success he began tracing
the fioat up the mountain, and to hi,
surprise discovered what is now
termed the South Vein, croppinp
above the surface and showing the
same metal. After further prospect.
ing the discovery was made that there
were three parallel, well. l.defined
hssures running through the country
IN an easterly and westerly course.
containing quartz and metal BEARING
similarity to that of the rich camps Of
Colorado and Mexico. Being ia.
mliiar with the ores Of those countries.
The discoverer began to ascertain the
value OF the new find. After careful
testing the ore was found to be
equally as rich, or richer for surface
than that of Colorado and Mexico
After locating what claims he deemed
sufficient, ne invited his neighhors to
come and partake of the remainder of
the El Dorado, which they readily
did, and staked five more claims,
covering all the groupings that
showed mineral, reaching nearly to
the summit, where the veins become
covered with heavy surface. All
parties, being satisfied with their ex-
tent of territory, began prospecting
the surface of their ground, sinking
test shafts, open cuts or adits, uncov.
ering chutes of ore along the differ
ent veins and claims for distance of
over 5000 feet, showing an immense
chain of ore chutes. Being thorough
ly satisfied with the way in which the
veins broke through the heavy gran
lts bars and porphvry dykes, showing
evidence OF peImanency, about the
middle of August more permanent
work was commenced in the way of
development. The owner of the
Horn Silver began sinking a shaft OH
the North Vein, (going down about
thirty feet) from which he took out
several tons of good ore, which is now
on the dump. Finding a more ac-
cessiole place and richer ore on the
South Vein, changes his operations
and commences tunneling, striking a
body of rich chloride and sulphide
ore. This tunnel was driven sixty
five feet, from which was extracted
the ore that WAS milled at Banner.
The ore now on the dump, between
twenty and twenty-five tons, is of the
same character, and this would also
have been milled had it not been for
the early storms shutting up the road.
We did not get the exact figures OF
the mill run, as they are know only
by the owner and mill officials. How
ever, it has been admitted to be the
highest grade surface ore ever milled
in this county. The owner is now
sinking shaft at the heading of the
main tunnel, to attain depth. This
shaft will be continued down 100
feet from tunnel level The ore still
continues down. The vein is getting
much larger, showing some change IN
the character of ore, it being now
more of a combination of chloride,
suIphde, ant;monal and ruby silver,
occasionally the quartz being covered
with hative, with a small per centage
of gold. This vein bids fair to break
the records, as producer, from pres
ent showing. 1t is also beautifully
located for working-much more so
than the Henrietta as her work will
he principally shafts, being 5000
feet east, much lower and not so alb
rupt. The intention is to extend her
shaft down this winter. The present
working shows very fine ore. This
is the only property on the hill that
cannot be opened to a great depth by
a system of tunneing. The camp
undergoes rather slow process OF
development, the properties being
owned by men of moderate means,
depending partially on the output
The camp being struck in mdsum-
mer, winter quarters had to be erect
ed, wagon road built, water rights
secured and bitches taken out, all
costing money and hard work'
Scarcely ample time was allowed tor
completion before winter, yet the
owner of the Horn Silver group butt
wagon road to his mines, and con-
structed very good winter quarters.
His mode of operations shows that
he-Mr. Dunn came to stay. tie is
the sole owner of this famous group
of FIVE properties, and thorough mi
ner and worker. West of the Horn
Silver group, and on the same VEINS,
