three or four miles norfheasterly: farther
than that 1t has not been observed. but il
undoubtedly continues under the lava
overfiows TO the west and the lacustcne
deposits and ayas to the east. 1t is one
of the series of porphyrys that forms the
contact with dolomite in north Custer
county where rich gold and silver veins
combined have been formed also having
the same trend and dip. and commonly
classed among the family OF metmorphia
and sedimentary eruptive rocks that con-
stitute The Saw Tooth Mountain range.
There is a quartzite dykein the Atlanta
1900 feet from the east end line of Atlanta
No. west;and directly north OF the vein of
mother lode from this dyke in nearly
every direction numerous segregated free
gold veins have been found and the dyke
itself carries gold aud trace of silver.
VEIN FEATURES lt
The Atlanta Gold and Silver Consoli-
dated mines are situated on the north
east and south west slope of Atlanta
mountain, 1000 feet above sea level, PIG
feet vertically below the apex Of the
mountain and the highest point on the
vein on the surface is 1900 feet vertically
above the confluence OF Grouse creek and
Yuba river. The point appears on map al
place commonly called the BLOW Out, I"
The property consists Of three full claims
l5OOx6OO feet, two fractional one contain
ing ID 81 acres the other containing 16. 68
acres and three mill sites on the east bank
OF the Yuba river and north bank of
Grouse creek. The strike or trend of vein
is north 70 degrees east and south 10
degrees 10 west, following the bedding of
the country rock, and practically follow
ing the dip which is 90 degrees to the
south from the horizontal. The dip
changes with depth as in the lower levels

it joins the Buffalo west end dine, the

the company owns over 10000 lineal feet

over 1880 lineal feet of measurements on
mother lode and small veins or lodges, and
all carry free gold. in assay values from
