ANTIMONY. 
A quartz vein carrying the sulphides of iron and antimony was 
lately found on Manila Creek. The vein is located on the hill slope 
west of the upper end of the creek and as traced by surface float has a 
length of about 3,000 feet. It has an elevation above sea level of 
approximately 800 feet at its southwest end and 1,200 feet at its 
northeast end. Apparently it dips at a moderate angle toward the 
northwest. The thickness is not known, since at the time it was 
visited by the Survey party no exposure of the vein in place had been 
made and all information concerning it was derived from loose mate- 
rial on the surface, part of which may of course be considerably 
removed from its source. Pieces of the float, however, indicate that 
locally the vein reaches a width -of 2h feet, but that its average width 
is much less, probably about 8 or 9 inches. The best ore occurs as 
bunches or irregular streaks through the quartz and usually shows the 
reddish color resulting from partial oxidation or a s ain of iron oxide. 
A prospect hole, supposedly on the dip of the vein, has been driven for 
a distance of 60 feet into the hill, but the vein was not visible at its 
lower end. The hole was located in loose surface material and schist 
bed rock considerably broken and so much displaced that it was not 
possible to make any reliable observation on the ore body. Besides 
antimony the vein carries some gold. 
GOLD. 
*As yet no gold-bearing veins of proved value are known in the Nome 
region. The occurrence and character of quartz veins have been pre- 
viousty described, together with some general statements regarding 
them, and it was pointed out that the more highly mineralized veins 
are the small ones such as are numerous in the schists of the Anvil- 
Glacier Creek divide or the region north of Rock Creek. There was 
some prospecting on gold-bearing quartz veins in this vicinity during 
the summer of 1906, principally on the west side of Anvil Creek, above 
Specimen Gulch. 
GRAPHITE. 
Graphite occurs abundantly in portions of the schists included in 
both the Nome and Kigluaik series, but is not known in commercial 
amounts within the area covered by the Nome and Grand Central 
sheets. Just north of the Grand Central area, however, in the upper 
valleys of Grand Central River and Windy Creek, and especially in the 
vicinity of the divide between these two streams, there are graphite 
deposits of considerable size. Their occurrence, as well as that of the 
graphite to the west of Cobblestone River on the north side of the 
Kigluaik Range, has been known for a number of years, but so far no 
effort has been made to develop them.
