CholInr-Poto.i Rcuort.

We have received II copy vi the An
nual report of the Chollar-Potosi Mining
Company for the fiscal year ending June
|, 1869. II is arranged in pamphlet
form, and is very neatly printed and
carefully prepared in every respect.
1t contains the reports of \. X. p. Har-
mon, President; l. II. Requa, Superin-
tendent and W. +. Dean, Secretary.
The report of Superintendent Rcqua'
contains so much matter az interest
relative to this leading mime, that from
it we condense the following tens
Daring the year specified there WIS
extracted by the company Il, 200 tons
of ore, obtained from the following see
tons Of the mine: Blue Wing, 35,3as
tons; New Tunnel, 6,7sl toas; crop
pings, 3,05T tons Average yield per
ton, 500 10; cost of milling. per ton,
Sl3 10; actual coat of extracting, per
ton, 81 30. As in previous years, the
ore supplies have all been obtained
from the old mine, the Blue Wing see
ton affotding the larger portion That
particular section has already yielded
about 81, 900, 900, and 'iS still very far
from being exhausted.
Nsw FUNNEL.
Work on this adj, was commenced in
the month of December 1868. The
starting point is at the surface immc
diately over the southern "ud of Blue
Wing stope. At 2lO feet west from The
mouth fine ore was met with open
inps we're made to the north aad south ;
both portions afforded ore of excellent
quality. The deposit has 0eeu stopped
out from the tunnel level upward 30
feet, giving an average width OF Is
feet aud a length of li0 feet, with good
ore, carving north and widening To the
west. This section, situated as 1t is
100 feet west Of any part Of the niue
yet worked, aud producing ore superior
in quality to she average extracted from
Blue Wing, with the extent OF country
and strength of the Vein, gives good
cause to presume it will continue 10
yield largely for twelve months to come.
of the deposits now nffording ore, an
estimate has been made on the quality
remaining measurements and hSureS
give the result as IL, 900 tons.
OF the amount of low grade ore in
the niue no accurate estimate can b.
made. This much j. knoyu, the quaint
ity is immense aud will be II source ct
large revenue TO the comp,nN after tue
completion OF the railroad 10 the Car
son River, owing TO the facilities for
cheap transportation oi ores, materials.
aud supplies hat this road will afford,
aud the very low rates that ore eau be
milled for BY water power, place the
matter beyond II questions that there are
hundreds of thousands of tons OF ore
in the mine that will ne extracted aud
milled, each ton of which will Civ" 10
the company II profit.
About two months ago work com
mencod on the Grass Valley tunnel for
the purpose of putting IL ia condition
for future use. At u point 800 feet
from the mouth of the tunnel = cave
had occurred which developed II large
body of quartz. Thirty feet OF the
above samples were taken and asSaycd,
giving good results. Since this quartz
was found farther prospecting shows
the deposit TO be large, and it promises
to Weld tens of thousands of tons OF
good ore. The air being foul, work has
been suspended there until a connection
Gun be made with the Potosi tunnel.
After ventilation is complete work will
be resumed aud this section thoroughly
prospected.
During the year there have been
I,5I3 feet oil drifts aud wines made,
and 223 feet of main incline sunk.
NEW SHAFT.
All the machinery, ropes and pumps
connected with this work are in good
condition. Main incline has been sunk
o23 feet. From that II d:itt was run oil,
making Il station l,2I0 feet deep, verti-
cal measure from mouth OF shaft. At
the l,2lO-foot station, also from the
1000 and 100 foot stations, long drifts
have been run in various directions
prospecting for ore. UP to this tine
these efrorts have not been successful.
The barren belt passing through the
lode a, this point is much greater than
was anticipated. II upon n more thor
ough examination OF the i,2IO-i"ot
level no ore should be found, sinking
will be resumed and other stations made
to prospect from.
In addition to the ore extracted by
the company, there were large amounts
extracted under contract with various
parties from the old Chollar workings.
The groupings, waste dump piles aud
other sources, making the total yield OF
the mine for the year 1926 tons.
