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): EARLY WORKS FOR GOLD (1908 AND LATER); 1936 A PORTION OF THE PROPERTY WAS LEASED TO W.B. WORLOCK WHO MADE TWO SMALL SHIPMENTS.

Comment (Deposit): MAIN QUARTZ VEIN VARIES FROM 3 TO 10 FT. THICK, BUT THE ALUNITE IS FOUND IN SHEETS SEPARATING THE VEIN FROM THE WALL ROCK. THESE SHEETS ARE 3 INCHES TO 1 FT. WIDE. SIZE/DIRECTIONAL DATA GIVEN IS FOR ALUNITE DEPOSIT ONLY. VEIN EMPLACED ALONG NW-TRENDING FAULT.

Comment (Workings): PROPERTY DEVELOPED BY A 250 FT. SHAFT, A TUNNEL, AND SEVERAL THOUSAND FT. OF WORKINGS. SHAFT HAS LEVELS AT 50 (TUNNEL), 130, 200, AND 250 FT.

Comment (Geology): THIN ALUNITE VEIN REPLACES GOUGE (?) IN SERICITIZED RHYOLITIC TUFF. QUARTZ VEINS 3-8 FT. WIDE, MILKY AND VUGGY AS WELL AS BRECCIATED. SEPARATED FROM WALLS OF POST ESMERALDA(?) VOLCANIC ROCKS BY ALUNITE SHEETS 3-12 INCHES THICK.

Comment (Deposit): SEE RECORD M233181, GOLDEN PEN GOLD MINE, FOR INFORMATION ON GOLD DEPOSIT AT THIS SITE. ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV

Comment (Production): NO PROD OF ALUNITE BUT SOME GOLD AND SILVER PROD. SCHRADER ( 1914 ) REPORTS CONSIDERABLE PRODUCTION OF RICH GOLD ORE.

Comment (Reserve-Resource): INSUFFICIENT DATA FOR RESERVE EST

Comment (Reserve-Resource): MAIN RESOURCE IN THIN VEINS ONLY; POTENTIAL IS POOR

Comment (Location): OLD BOVARD DIST. IN GABBS VALLEY RANGE. SECTION LINES UNSURVEYED. SECTION INFERRED BY LINE EXTENSION.
