The Hi-Yu Mine is a gold 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): HELEN S. VEIN HAS AN AVERAGE STRIKE OF N 65 W AND IS VERTICAL OR DIPS 80-85 S; AVERAGE WIDTH 10-12 IN. HI-YU VEIN IS SIMILAR; STRIKES N 75 W. MANY FAULTS, BUT NONE WITH MORE THAN 20 FT. OF OFFSET; ALL MOVEMENT APPEARS TO HAVE BEEN NORMAL.
Comment (Location): USGS MF-413, LOC. 51. MILL MARKED ON LIVENGOOD (A-1) ALONG MOOSE CREEK, A TRIBUTARY OF FAIRBANKS CR. DEPOSITS TREND NW OF MILL, ALONG DIRT ROAD. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).; PREVIOUS QUAD DESIGNATION = FAIRBANKS 1:250000
Comment (Development): MINE OPERATED FROM 1913 TO 1940 (EXCEPT FOR 1 OR 2 YEARS) AND IN A FEW YEARS BETWEEN 1941 AND 1951. MILL ON PROPERTY
Comment (Deposit): MANY QUARTZ VEINS, SOME ALONG FAULTS AND MOST OFFSET BY FAULTS, CONTAIN FREE GOLD AND SULFIDES INCLUDING STIBNITE, ARGENTIFEROUS GALENA, ARSENOPYRITE, PYRITE, AND SPHALERITE. SOME OXIDATION PRODUCTS. SOME SILICIFIED SCHIST BETWEEN VEINS MIGHT CONSTITUTE LOW GRADE GOLD ORE. CONSIDERABLE SURFACE ENRICHMENT IN PLACES. STIBNITE IN KIDNEYS AND IRREGULAR VEINS. GOLD CONTENT VARIABLE; HIGHEST WHERE SULFIDES ARE MOST ABUNDANT. HANGING WALL OF MAIN VEIN MARKED BY A FAULT; SOME OF SULFIDE MINERALIZATION WAS EARLIER THAN THE FAULTING.
Comment (Workings): WELL OVER A MILE OF WORKINGS, PLUS STOPES; OTHER OPEN CUTS, PROSPECT PITS, ETC.
