| Deposit | BOTH CREEK AND BENCH GRAVELS NEAR CONFLUENCE OF GRUBSTAKE GULCH AND WILLOW CREEK HAVE BEEN MINED FOR PLACER GOLD INTERMITTENTLY SINCE 1897. GOLD PROBABLY IS FROM SMALL QUARTZ VEINS FOUND IN MICA-SCHIST BEDROCK (COBB, 1973). THE BEDROCK IN THE GRUBSTAKE GULCH DRAINAGE IS JURASSIC (?) QUARTZ-ALBITE-CHLORITE (+/- GARNET-BIOTITE) PELITIC SCHIST; MINOR EOCENE HYPABYSSAL MAFIC INTRUSIONS AND SERPENTINIZED CRETACEOUS ULTRAMAFIC ROCKS. GOLD HAS BEEN FOUND IN GRAVELS UP TO 70 FT DEEP IN THE AREA (GREEN AND OTHERS, 1989). |
