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): THE AREA INCLUDES THE ARIZONA, MAUD, ROUGH RIDER NO. 2 , NEVADA, AND UTAH CLAIMS.

Comment (Location): THE LABEL "ALVARADO MINE" IS MISLOCATED ON THE USGS 7.5 MIN. GOLD HILL MAP.

Comment (Workings): WORKINGS CONSIST OF OPEN CUTS, INCLINED STOPES, AND TWO ADITS.

Comment (Production): ONLY PRODUCTION WAS FROM THE MAUD CLAIM, WHICH PRODUCED $33,986 OF SILVER. NO URANIUM OR VANADIUM PRODUCTION.

Comment (Deposit): FOR ORE SHOOTS IN CONTACT WITH QTZ. MONZONITE, THE ORE WASTE BOUNDARY IS THE LS.-QTZ. MONZONITE CONTACT. THE BOUNDARIES OF ORE SHOOTS IN LS. ARE DETERMINED BY ASSAY RATHER THAN BY ABVIOUS MINERALOGIC CHANGE. ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV; 2 UNPUB REPT; 4 OTHER SRC

Comment (Workings): PRINCIPAL, INCLINED (AT 60-65 DEGREES), 252 FT. DEEP SHAFT CONNECTING THE 40, 60, 100, 150, AND 200 FT. LEVELS. THE FIVE LEVELS, WITH ASSOC. DRIFTS AND CROSSCUTS, TOTAL APPROX. 1750 FT. OF WORKINGS. NUMEROUS SHALLOW TO MODERATELY DEEP SHAFTS, PITS AND TRENCHES ARE ON MANY SMALL ORE SHOOTS, MOSTLY IN BEDDING REPL. SKARN ZONES, ELSEWHERE ON THE PROPERTY.

Comment (Commodity): THE URANIUM MINERALS WERE FOUND AS WEATHERED COATINGS. MALACHITE REPLACES PLANT FOSSILS.

Comment (Commodity): BULLION ASSAYS FROM THE ALVARADO, CANE SPRINGS, AND GOLD HILL MINES INDICATED A FINENESS OF 0.750 TO 0.850. SOME OF THE GOLD WAS REPORTED TO BE 0.950 FINE.

Comment (Production): NO FIGURES, IN 1933 AND 1934.

Comment (Deposit): DIMENSIONS GIVEN ARE FOR THE MAIN ORE BODY; A SMALLER ORE BODY HAS BEEN STOPED FROM THE 100 FT. LEVEL TO THE SURFACE JOINING THE MAIN ORE BODY AT THE 60 FT. LEVEL. AN ORE BODY ON ORE BODY ON THE 60 FT LEVEL WAS STOPED TO APT. ABOVE THE 40 FT. LEVEL. SEVERAL SMALL ORE PIPES ARE ON THE 200 FT. LEVEL.
