62 ALASKAN MINERAL RESOURCES IN 1906. 
PRINCE OF WALES ISLAND. 
Near Hollis, on the north side of Twelvemile Arm, are the Cracker- 
jack, Puyallup, Flora and Nellie, Dew Drop, and Julia claims. The 
most work done in this section was on the Julia claim, situated on 
Harris Creek, 2 J miles southwest of Hollis and from 800 to 1,200 
feet from tide water. At this point a shaft 100 feet deep has been 
sunk on an incline of 25°. At the 50-foot level a drift has been run 
35 feet long, and another started at the 100-foot level. The ore body 
is a quartz vein, striking north-northwest and dipping 25° SW., in a 
black-slate country rock. At the surface it has a width of 1 foot of 
solid quartz. This, however, becomes a stringer lead, consisting of 
numerous quartz veinlets across a width of 4 J feet, at a depth of 100 
feet. The ore contains auriferous pyrite, with some galena and 
sphalerite. An arrastre was installed and mining on a small scale is 
to be advanced during the winter. 
Investigations at the Cracker jack mine were made by the Brown- 
Alaska Company early in 1906, but no development work has since 
been done. The Puyallup mine was leased and prospected by two 
miners, who discontinued work in February, 1906. The other prop- 
erties in this section were idle. 
At the Treasure group, on Granite Mountain, which promised well 
to become a producer, only small improvements were made within 
the year, and on the near-by claims the assessment work alone was 
done. 
At Dolomi a small crew of six men was employed and developments 
were furthered on the Valparaiso vein. The shaft has been extended 
to 180 feet in depth, and at the lower level the pay streak is reported 
to have widened from 16 inches to nearly 30 inches. On the Amazon 
claim limited explorations were also made underground. On the 
Paul and Lakeside claims inclined shafts 60 feet deep have been sunk 
and drifts started on the veins. The properties of the Golden Fleece 
Mining Company were sold by the action of the court early in the 
year and no attempt was made to operate them. 
The prospects at Dakoo Harbor, on Dall Island, southwest of Prince 
of Wales Island, have been developed in a small way during the year, 
though no important improvements in the ore bodies are to be noted. 
The deposits at this point are quartz veins and lodes of low-grade ore.

GRAVINA ISLAND. 
At the Gold Stream mine, on the east side of Gravina Island, opera- 
tions were renewed July 15 and a dozen or more men were employed 
until the 1st of October. An exploratory drift was extended in a 
northwesterly direction from the shaft, and a body of good ore was
