The Deep Creek and Tributaries Placer is a gold and tin mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Geology): AT INNESVALE GULCH MOST BOULDERS ARE ROUNDED SANDSTONE. ROUNDED AND ANGULAR QUARTZITE BOULDERS AT HOKELEY GULCH. COARSE GRAINED BIOTITE GRANITE COBBLES IN GRAVELS. ; MAJOR.UNITS: BEDROCK IS MAINLY PHYLLITE AND SLATE. BEDROCK SURFACE SLOPES SOUTHEASTWARD.

Comment (Deposit): STREAM GRADIENT 50-100 FT. PER MILE. DESCRIPTION REPRESENTS DEEP CREEK HOKELEY GULCH, INNESVALE GULCH, AND BENCHES SOUTH OF DEEP CR.. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.

Comment (Location): USGS MF-371, LOC. 26. COORDINATES GIVEN ARE FOR BENCH 1/4 MI. SOUTH OF CREEK, WHERE DRIFT MINING IS BELIEVED TO HAVE BEEN CENTERED. SEE TANANA (A-2) LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Development): GOLD FOUND ON HOKELEY GULCH AS A RESULT OF AN EXTENSIVE DRILLING PROGRAM, 1913. SHAFTS SUNK 130 FT. TO BEDROCK, MAINLY THROUGH FROZEN SILT; 6-8 FT OF GRAVEL BENEATH SILT. MINING BY LARGE-SCALE DRIFT OPERATIONS. USBM DUG PROSPECT HOLES AT HEAD OF CREEK, 1954-56.

Comment (Deposit): GOLD IN BASAL FEW FEET OF GRAVEL AND IN TOP FOOT OF WEATHERED BEDROCK. BENCH NORTH OF CREEK IS CROSSED BY SMALL TRIBUTARIES IN POORLY DEFINED VALLEYS. IN MOST PLACES BEDROCK IS OVER 100 FT. DEEP. MINING IN 1931 WAS ON INNESVALE GULCH; 5-6 FT. OF GRAVEL BENEATH 90 FT. OF MUCK; GOLD IN LOWER 2 FT. OF GRAVEL AND UPPER FOOT OF BEDROCK. MOST OF DRIFT MINES APPEAR TO BE ON BENCH 1/4 MILE SOUTH OF CREEK.

Comment (Workings): ALLUVIUM FROZEN
