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 (Development): MINED SINCE 1900; ABOUT 1/3 OF PRODUCTION TOOK PLACE BETWEEN 1898 AND 1907; MAJOR MINING ENDED 1962; SMALL-SCALE MINING SINCE THEN

Comment (Location): COORDINATES GIVEN ARE FOR ARBITRARILY CHOSEN POINT ON SLATE CREEK; FOR LOCATION OF INDIVIDUAL PLACER WORKINGS, SEE ADGGS GR 28, FIGURE 1 LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Deposit): THREE AGES OF GRAVELS CONTAIN AU: 1. PRESENT STREAM GRAVELS, 2. BENCH GRAVELS OF GLACIAL ORIGIN ON W SIDE OF LOWER SLATE CREEK, 3. TERTIARY CONGLOMERATE; STREAM GRAVELS ARE THE SOURCE OF NEARLY ALL PRODUCTION, BUT BENCH DEPOSITS CONTAIN ECONOMICALLY SIGNIFICANT VALVES LOCALLY; RICHEST PLACERS WERE AT AND BELOW JUNCTION WITH MILLER GULCH; CLAIMS ABOVE MILLER GULCH MUCH LEANER THAN THOSE BELOW

Comment (Geology): CREEK FOLLOWS FAULT ZONE SEPARATING UPPER PALEOZOIC SLATES OF MANKOMEN FORMATION FROM CONGLOMERATE, QUARTZITE AND TUFF OF OLDER CHISANA FORMATION; VALLEY MAY BE UNDERLAIN BY GRABEN CONTAINING CURIFEROUS CONGLOMERATE, SANDSTONE AND SHALE OF TETIARY GAKONA FORMATION ; MAJOR.UNITS: SEE GEOLOGY COMMENTS ; REG.COM: PROXIMAL SOURCE TERTIARY CONGLOMERATE AND BENCHES OF GLACIAL ORIGIN; ULTIMATE SOURCE PROBABLY IN ROCKS N OF DENALI FAULT; AU PROBABLY RECONCENTRATED SEVERAL TIMES
