A GOOD REPORT
ON CORONA MINES

Capitalists
By Oliver E. Common, a Prominent
Mining acknowledgements
Property Highly.

A few days ago Oliver E. Conner,
prominent mining engineer and ex-
pert, arrived in this city for the pur-
pose of mixing an examination of the
properties of the Corona Consolidated
Gold and Copper Comply, and after
spending several days at the property
and giving it most thorough and
critical examination submitted a re-
port to the company and to the people
for whom he had made the examina-
ton. The following paragraphs are
taken from the report which certainly
should interest capital which is look
ing for a good mining investment.
The report only con firms what has
been said on several occasions by the
Journal Miner after a representative
of this paper had personally visited
the property.
The group of mining claims owned
and controlled by this company are
situated in the foot hills of the
Bradshaw range of mountains, being
y miles Southeast of Prescott, Arizona
and miles from Mayer, a shipping
point on the Prescott and Eastern
railroad.
1.-THE adjacent mountains furnish
sufficient timber and the property
water for carrying on all mining
operations.
"Many of the veins found on this
property are highly mineralized and
ali contain certain values and quanti-
ty of ore.
/ | confined my examinations more
particularly to two massive veins
which showed persistency as to hori-
zontal projection, quantity and
/ quality of ore.
"On the Deer's Rest claim find a
we'll defined assure vein of ore ID
| feet wide. There is a very prominent
out cropping near the crest of the hill
which has all the appearance of being
the apex Of an ore shoot. From
actual exposure this ore shoot is 80
feet long and dips into the hill at
approximately 10 degrees. The ores
occurring ara in a deeomposed state,
being chiefly copper and iron carbon
ates carrying free gold and some
silver, with a cementing gaugue ma
terial of quartz and calcite. This
vein is very strong and persistent and
in my opinion is the mother lode in
| this camp. An average sample taken
across this vein IL feet wide yields
, 50 ounces of gold go ounces of
silver, giving total value of s62. 80.
The continuation of this vein on the
Christmas Gift claim, COO feet from
the above ssmDling, yielded ESQ
ounces of gold, $40 ounces silver,
total values, $50. %. The character
and value of this ore Is almost identi-
cal with that found in the Deer's Rest
vein. proving conclusively this veins
Continuity.
"Hhe other vein of particular merit
is located on the Silver Bell claim.
This is also a assure vein, having a
width varying from one to two feet.
The ore occurring is chiefly sulphuret
of iron, containing both gold in free
state in the quartz matrix and also
accociated in the sulphuret of iron.
This is particularly gold yielding
vein, there being only a small per
ceniage of silver and copper present.
/ From the amount of work done by
old prUsPectors on this vein, it is
| evident they realized good values,
| judging from the gold contents of the
ore as sampled by myself. Gold 4. SO
/ ounces. silver 1.40 ounces, giving a
total of 500 81 per ton. This represents
an average value of this vein feet
wide at the bottom of the shaft in
old tunnel 20 feet deep.
"Sampling from the Copper Hill
vein and claim yielded LA ounces
gold, L.9O ounces silver, As per cent.
copper, total value s46.51.
Sample taken from the Peacock
vein struck in the tunnel on the
Deer's Rest claim; vein feet wide,
yielded gold 50 ounces, silver 40
ounces, copper 1913 per cent, total
value $50 90.
1.-THE present plan of driving the
tunnel in the Deer's Rest claim in
order to develop Deer's Rest vein is
recommended; for this tunnel should
cut this vein at about $50 feet in
depth, and 1t is my opinion that this
massive vein viii carry gold contents
down, however the Characteristic quail
tiles Of the ores at as present expos
ed will change with depth to sulph-
uret of iron with the copper contents
very much improved. The gold will
be partly free and associated with the
copper and iron. This will give you a
free milling and concentrating ore,
with exceptionally high grade coneen-
trates. This body of ore when cut by
this tuncel at $50 feet in depth will
give you an enormous tonnage and
cost of mining will be below the aver
age cost per ton in other mining
camps.
"Alter the Deer's Rest vein has been
cut and values and quantities Of ore
determined a shaft should be sunk
above the Presnet tunnel on the
Silver Bell claim. This vein has all
the markings of making big and
profitable producing mine and all
work done on same should be done
with a view to perrnaD' ncy-
Taking everything into CONSIDERS
tion As 70 relative position, to rail-
road. water and timber abundant Tor
all mining purposes, the persisteney,
'onautity and values in the ores tound
in the silver Bell and Deer's Rest
veins make this very attractive
mining proposition for the investment
of capital.
