martin.] GOLD DEPOSITS OF SHTJMAGIN ISLANDS. 101 
iofe correlation across 11 miles of rushed country which is ofeoloedc- 
illy unknown. Such correlation is especially hazardous in view of 
the fact that on the adjacent mainland of the Alaska Peninsula there 
ire large areas of both Mesozoic and Tertiary andesites which resem- 
ble the andesites of both these Unga localities as much as the latter 
resemble each other. He therefore would conclude that the Apollo 
ieposits may be either of late Mesozoic or of Tertiary ago. 
NEIGHBORING DEPOSITS. 
The King mine, about half a mile north of the Apollo mine, has pro- 
luced a small amount of gold. The occurrence is said to be similar to 
:hat of the Apollo and is believed to be on the same lead, for it is in 
;he line of strike of the latter. 
The Shumagin group of claims, on Baralof or Squaw Harbor, about 
I miles north of the Apollo mine, is said to be a similar occurrence, 
rhe development here has been principally assessment work. 
Becker reports intensely decomposed andesites, heavily charged 
vith pyrite, at Red Cove on Popof Island, about 9 miles northeast of 
\pollo. 
The larger part of Unga Island is made up of similar andesites and 
iacites, and evidences of mineralization have been seen by the writer 
it various and widely scattered places. So far as they have been 
examined by the writer none of these rocks contain workable amounts 
)f gold. 
SAND POINT BEACH PLACERS. 
The beach sands near Sand Point, on Popof Island, were washed for 
rold during the summer of 1901. The exact locality is about 1| miles 
outh of Sand Point post-office and just south of the low sand spit 
u'ojecting into Popof Strait. The productive beach is about three- 
burths of a mile long. The amount of gold taken out during the 
months of July and August is estimated at about $5,000. From 20 to 
:0 men have been at work with rockers washing the coarse sand and 
gravel. All of the gold is found below mid tide and most of it around 
rig stones at the level of low tide. It is said that most of the men 
tiake about $4 a day, but a few have clone much better than this. The 
ocal price for gold in September, 1901, was $18.75 per ounce, which 
s said to be considerably below the actual value. The gold hitherto 
obtained is fairly coarse, the finer dust probably having been lost 
hrough the inexperience of the men, who are largely fishermen. 
The gold is undoubtedly derived from neighboring mineralized 
ones in the andesites, which make up the greater part of this and 
Jnga Island. The deposits known at present to be gold bearing are 
estricted to the low-tide level of about three-fourths of a mile of 
>each. Other similar deposits will doubtless be found on the adjacent 
hores.
