What is destined to be one of the
prosperous quartz properties In jose
phine county Is. the Michigan mine, To-
Gated on the Applegate river. one
aud one-half miles from Murphy and
eight miles south of Grants Pass.
The property is now owned by the
Oregon Strong Ledge Mining COM
pany, with headquarters at Char
lotte. Michigan. In charge Of the
property Is Adolph Maier, mining
engineer Of rare ability and one Of
the most progressive mining men In
western America. Mr.. Maier is a
Heidelberg man, which is saying that
lie has passed through the greatest
institution of Its kind on two conti-
nents. He also took post graduate
course at the Golden School Of
Mines at Golden, near Denver. Mr..
Maier makes his home In Grants
Pass, and Is a much appreciated men,
ber of the mining colony here. He
has delved in the hills Of the west
ern states and particularly In Col
orado.
Mr.. Mailer is now erecting at the
Michigan mine 25-ton mill and ex-
poets to have II In operation with
in go days from this date. II Is OF
the very latest pattern hydro-electric
chlorination process, with complete
Shining and concentrating appara.
tus. When ton of ore goes through
this mill from first to last there IL
no hope of any man making his salt
from the residue, as extraction OF
geld is practically 100 per cent.
All work, fitting and all equip
ment in general is being put in In
flrst-class manner. and the Michl-
gan mine and mill will prove one
Of the big assets OF the county.
Eleven samples taken by Mr.
Maier from various portions Of the
i1ine run as follows: $11,20
s1i.40, $12.1O, $3.50, s1s, $3.50
$500, s22.4O, 1920, $3.50 and
s21.60, all OF which shows what Q
handsome profit will result from the
successful milling process which II
being Installed.
The ore also responds well to con
centratlon. The following fact
were developed as to ratio OF concen
tration and ore value; Clayton ant
Hampton put 20 tons into one, orr
value $12.05, concentrating value
s241.17; Tacoma Smelling company
90 tons into one, ore value s13.16
concentrating value s263; Claytol
and Hampton, 20 tons into one, or
value $60.29, concentrating valu
s252.67; w. q. Wright, 30 tons int
one, ore value $4O.73, concentratin
value $1,GS9.40; Clayton and Hamp
ton, 40 tons into one, ore valu
$l902, concentrating value 1851
Is. The several tests show tina
tho ore averages t29.04 In gold, wit
ratio OF concentration OF 32 int
one. Maier's tests did not reac
quite the high ratio OF concentrs
tlon as the foregoing, because h
first extracted all free gold contain

The mine Is equipped with machir
