that the $500 tons still standing il
the slopes will show an average value
of SO per ton when mined If the
crosscut from the 3e0-foo level en-
counters the ore, it will open up a
block 100 feet long by 100 feet deep,
and taking width of two feet, this
block would contain 2,400 tons. Re-
cent shipments from the bottom of the
mine indicate 4 value of not less than
$50 per ton, so that this 2,400 tons
would have gross value of $4,000.
Therefore on this basis there would be
$500 tons of ore having a gross value
of $4,000, equivalent to an average
value of $17.75 per ton. We believe
that the conditions existing in the mine
warrant us in assuming this tonnage
and value in the probable ore reserves.
With proper milling methods the
Phoenix ore should be mined and
milled, including treatment losses, at
a cost not to exceed $40 per ton, leav-
ing net value of $775. or total net
profit of $47,050 We are further of
the opinion that more systematic de-
velopment of this lease will show a
largely increased tonnage.
The Victor Ground.
On the Victor lease the drift on the
900 foot level has been in the values
from the mine indicate that since the
date of our visit the further develop
ment of this drift shows that the values
and widths are increasing so that there
is every likelihood THAT the ore body
stoned out on the 200-foot level will
be continuous to the 300-foot level. We
therefore feel justified in estimating
not less than. 10000 tons of probable
ore in sight on this lease, having an
average value of about $40 per son, or
total gross value of 100000.
This ore can be mined and milled, IN
cluding metallurgical losses, not to ex-
ceed $40 per ton, so that this block OF
ground would probably leave net
profit of 100000.
Another Good ore Body.
In the Grutt Balloon lease the same
vein which has been opened up on the
$50 foot level for length of 50 feet
has been cut at one point on the $50
foot level. An assay from three feet
gave a return of $14l per ton. The 81
feet opened up on the 35O-foot level
gives an average value of $34.30 for
width of three feet. This vein has mol
been cut at any one of the intermediate
points, nor has it been explored on the
1sO foot level. If it continues through
from one level to the other 100 feet
long. it will contain about 1000 tons
of ore. Considering the character o.
the fracture, it is safe to assume tha
- will extend considerably further
both in length and depth, and with thu
values shown will yield very hand
some profit Taking as basis OF cal
cnlation the average value of the 81
feet exposed on the 35O-foot level, OF
$34 so per ton, this ore would nave
oross value of sl30,s51. Allowing 81
/ for working costs and metailurgica
losses under existing conditions, W.
have a net value $s3,0S0. Every 100
foot extension along its strike VIII IN
crease the value by an equivalent
amount. and Judging by the character
of the ore exposure, continuance o.
values may be expected for some aus
tanee. If this ore body continues q
open up as shown in the Wine, 'hes'
fgures will increase rapidly. Inc @i4
working costs estimated above are nigh
and with proper milling facilities
m,ch lower figure can be attaineu anu
these profits proportionately ncfe"'eu
crown Vein Is Large.
The Coalition Crown vein, owing ''
10 size. will likely develop tonnage
very rapidly, and in its thoroughly
oxidized condition it will be ioun'
. without doubt that these values car
he easily extracted. As shown else
