The Wietchy Prospect is a gold and silver 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 (Deposit): VEIN AND STOCKWORK MINERALIZATION ON THE WEITCHY PROSPECT REPRESENTS A HIGH GRADE, MODERATE TONNAGE EXPLORATION AND DEVELOPMENT TARGET (FREEMAN AND ADAMS, 1989).

Comment (Location): THIS PROSPECT IS LOCATED ALONG THE LEFT FORK, RIGHT LIMIT OF AN UNNAMED CREEK DIRECTLY NORTH OF PORCUPINE DOME IN THE SE1/4 NE1/4 SEC. 8, T. 8 N., R. 11 E. THIS CREEK IS UNNAMED ON THE U.S.GEOLOGICAL SURVEY MAP, BUT IT IS COMMONLY KNOWN AS DOME CREEK. THE CREEK LABELED AS DOME CREEK ON THE U.S. GEOLOGICAL SURVEY CIRCLE C-4 QUADRANGLE MAP IS INCORRECTLY LABELED; IT HAS BEEN REFERRED TO AS WEST DOME CREEK IN SOME REPORTS (FREEMAN AND ADAMS, 1989, P. 12).

Comment (Workings): HAND TRENCHING COMPLETED IN 1989 AND SUBSEQUENT YEARS RELEASED FLOAT BOULDERS BEARING FREE GOLD. THE GOLD IN ROCKS IS ASSOCIATED WITH SILVER, ARSENIC, LEAD, ANTIMONY AND ZINC. FIRE ASSAY RESULTS FROM VEIN AND STOCKWORK MINERALIZATION AVERAGE GOLD 2.96 OUNCE OF GOLD PER TON WITH A HIGH VALUE OF 23.4 OUNCES OF GOLD PER TON. EXPLORATION ALONG STRIKE OF MINERALIZATION REVEALED A HONEY-COMB STOCKWORK AND WHITE QUARTZ BRECCIA SIMILAR TO THOSE ON PORCUPINE DOME (FREEMAN AND ADAMS, 1989).

Comment (Deposit): MINERALIZATION IN THE AREA OCCURS IN QUARTZ VEINS, STOCKWORKS, AND BRECCIA HOSTED BY INTERMEDIATE INTRUSIVES, METAQUARTZITE, PELITIC CALC-SCHIST AND METAVOLCANIC SCHIST OF THE BONANZA CREEK SEQUENCE. STOCKWORK SILICIFICATION AND QUARTZ-SERICITE-SULFIDE ALTERATION ARE DEVELOPED ON THE NORTH FLANK OF PORCUPINE DOME (FREEMAN AND ADAMS, 1989). HAND TRENCHING COMPLETED IN 1989 AND SUBSEQUENT YEARS RELEASED FLOAT BOULDERS BEARING FREE GOLD. THE GOLD IN ROCKS IS ASSOCIATED WITH SILVER, ARSENIC, LEAD, ANTIMONY AND ZINC. FIRE ASSAY RESULTS FROM VEIN AND STOCKWORK MINERALIZATION AVERAGE 2.96 OUNCES OF GOLD PER TON WITH A HIGH VALUE OF 23.4 OUNCES OF GOLD PER TON. EXPLORATION ALONG STRIKE OF MINERALIZATION REVEALED A HONEY-COMB STOCKWORK AND WHITE QUARTZ BRECCIA SIMILAR TO THOSE ON PORCUPINE DOME (FREEMAN AND ADAMS, 1989).

Comment (Exploration): Status = Active
