Mr.. j n. Wright, general manager of
the Extreme Gold Mining & Milling
Company, at the annual stockholders
meeting recently held in this city:
Since the commencement of opera
tions on the property of the company in
January, 1908, there has been expended
for labor and improvements, machinery
and equipments up to July lst, 1904, the
sum of S29, $50 "a paid for, and for which
the company is still owing the sum of
S4,92527 making total of S34, 1851
expended upon the property.
For said expenditure there has been
accomplished, the following:
Erection of all the bunk houses.
The erection of nine-room boarding
house.
Erection of large barn. Both the
barn and boarding house are supplied
with water, gravity system, from a
spring 400 feet distance.
Erection of a dwelling house.
Erection of a hoist building, and in
stallation of steam hosting plant, com
plete. Blacksmith shop at the mine.
Sinking and timbering shaft 80 feet in
depth, also excavating, drifting and
stopping of ores therefrCm. Said work
showing up immense bodies of ore.
Open cuts and assessment work upon
the Ruby and other claims.
Grading of wagon road to mill.
Cutting of about 100000 feet of lumber
and manufacturing cord wood for fuel.
Sinking and timbering Of well and
erection of pump house with pipe line
connection with tanks and mill.
Erection of ten stamp mill complete
and warehouse and the purchasing Of
all tools, machinery and supplies and
the payment of all labor incurred in the
accomplishing of the above.
Mining and milling Of 100 tons of ore
with the following results.
Started mill April 27, 1904, run to May
13. 9s days, treated l75 tons, free milled
| YOJls-Os dN cIdSC lSi tbh S-'-t'
Second run to May 2lst, 81 days, treat
ed l25 tons. Free milled $53S6O, aver
age per ton S43l.
Third run to June Goth, 254 days,
treated 600 tons, retorted IA ounces, 10
pvt.
June l4th, treated 5! tons of Ruby
ore, free mlled OF. 10 pvt. 20 gr.
June Both, treated IA tons from recent
lv discovered chute on the London lode,
retorted OF. 10 pvt. II gr
Fourth run to July lst, 81 days,
treated $50 tons, retorted 32 OF. pvt.
Combining above result by way of
summary.
800 tons yielded S929s9 averaging
SO. 10 per ton free milling; 794 tons re-
torted l79 OF. IL pvt. - gr. of a prob
able value OF $3.50 to$l6 per ounce.
81 tons Ruby ore nodded brick off OF,
10 pvt. 20 gr. averaging about 5000 per
ton free gold.
The concentrates resulting from this
run assay about $4,000 per ton.
1t must be remembered that this is
only the free gold that has been obtain
ed, and also this being surface ore mix
ed more or less with states and waste
that can be avoided when the property
is opened, it being impossible to separ-
ate them at this time, it had to all be
miled together. In addition TO the
above values all of which l have on
hand we still have the concentrates
which according to the assays runs from
SIS to 1912 per ton and as near as can
be estimated shows an ore value saving
of Sl00. Also fine cyanide gangue of
about 81 20 por ton value in the tailings
that is at present being lost and will
continue to be lost until cyanide or
some other suitable method of treat
ment is installed. The mill is now rum
ming steadily and satisfactorily. AS to
the future policy l would advise the
further development of the property by
the following additions:
A horse tramway from mine to mill to
transport the ore.
The installation of power drills for
sinking, drifting and stopping of ore.
Installation of small electric plant
sufficient to light mine and mill
The continuous operation of the pre-
sent plant to be enlarged from time to
| time as the development of the mine
will justify.
Upon the enlargement of the mill
would advise installation of cyanide
plant, or some other suitable method of
treatment for the gangues.
When the development has proceed
ed far enough to determine the best
point, would advise the sinking Of a
new and larger working shaft to tap the
ore bodies at q greater depth, and at
that time the erection of gravity tram
way to deliver the ore from the collar of
the shaft to the mill.
The said improvements should cost
not to exceed from SIS 900 to 100000.
From the time OF starting the mill up
to July lst, there has been almost a
steady downpour of rain, making it al
most impossible to get sufficient ore to
the mill TO keep it in steady operation.
Respectfully submitted,
j. n. WRIGHT,
General Manager.
