Deposit SMALL AMOUNTS OF GOLD AND TRACES OF CASSITERITE WERE REPORTED FROM PROSPECT HOLES DUG IN 1938; NONE COULD BE FOUND IN SAMPLES OF THE DUMPS TAKEN IN 1942. POSSIBLY THE MINING WAS ON BENCHES OF LONG CREEK THAT WERE CUT BY FLAT CREEK. MUCK AND GRAVEL WERE 14 FT. THICK AT PROSPECT PITS.
Deposit STREAM GRADIENT APPROXIMATELY 100-200 FEET PER MILE EAST OF WINTER TRAIL MARKED ON RUBY (B-6). SOME OF REFERENCES REPORTING MINING MAY REFLECT CONFUSION BETWEEN THIS FLAT CR. AND ANOTHER FLAT CR. TRIBUTARY OF TIMBER CR. NEAR POORMAN. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
