General comments

Subject category Comment text
Deposit 1000 FT. LONG BY SEVERAL HUNDRED FT. WIDE; MODEL NAME COULD ALSO BE: COMSTOCK EPITHERMAL VEIN.
Deposit CLAIMS WERE LOCATED BY J. F. SPRINGER IN 1937 IN A PREVIOUSLY STAKED AREA (STAKED PRIOR TO 1911). LINDGREN REPORTS A PRODUCTION OF $8000 FROM RICH ORE IN 1911. COUCH AND CARPENTER REPORT A PRODUCTION OF 31 TONS ORE YIELDING $5711 FOR 1911-1912. THE MATERIAL FROM THE OLD DUMPS HAS BEEN SHIPPED SINCE THEN, WITH NO RECORD OF THEIR RETURNS. ; INFO.SRC : 1 PUB LIT
