The Black Jack Prospect is a copper, silver, and gold mine located in Skamania county, Washington at an elevation of 1,759 feet.

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 (Location): NORTH BANK OF COPPER CREEK. NEAR CENTER OF SECTION, UNSURVEYED. PROPERTY CONSISTS OF 16 UNPATENTED CLAIMS. RECENT ACTIVITY ALSO WITHIN SECS. 3, 5, 8, 9

Comment (Deposit): SEE ALSO MRDS RECORD M700180

Comment (Development): PLACER GOLD ON COPPER CREEK LED TO DISCOVERY OF PROPERTY IN THE LATE 1890'S. IN 1974 AMOCO ACQUIRED PROPERTY AND DRILLED FOR PORPHYRY COPPER. THE EXPLORATION WORK WAS ENDED BY 1979. PLEXUS WAS DRILLING AND UNDERTAKING GEOLOGICAL AND GEOCHEMICAL EXPLORATION IN 1991

Comment (Deposit): DEPOSIT HAS BEEN GIVEN THE INFORMAL NAME OF A BRECCIA PIPE CU DEPOSIT, FOR WHICH THERE IS NO PUBLISHED MODEL. IN ADIT 1, PYRITE AND MINOR CHALCOPYRITE OCCUR AS SMALL PODS ALONG FRACTURE ZONES; PYRITE IS ALSO DISSEMINATED IN THE WALL ROCK. IN ADITS 2 AND 3, PYRITE IS DISSEMINATED IN THE WALL ROCK AND THE FRACTURE ZONES ARE BARREN.

Comment (Workings): 3 ADITS, 20 FT SHAFT, ADIT 1 IS 115 FT LONG, WITH A 25-FT WINZE, 80 FT FROM THE PORTAL. ADIT 2 IS 40 FT LONG, AND ADIT 3 IS 130 FT LONG, WITH A 15-FT CROSSCUT 80 FT FROM THE PORTAL. ALL END JUST SHORT OF BRECCIA BODY

Comment (Geology): BRECCIA IS NOT A PIPE, BUT RATHER AN AREA OF ABUNDANT FRACTURES GRADING INTO BLOCK BRECCIA (STOCKWORK)

Comment (Deposit): Discovery Year: LATE 1890'S
