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 (Reserve-Resource): POTENTIAL RESOURCE ESTIM. BY R. B. HALL BASED ON 1974 RECON PLUS PUB AND UNPUB DATA, THIS DEPOSIT NOT CONSIDERED VIABLE ALUNITE RESOURCE
Comment (Geology): ALUNITIZATION IRREGULAR IN DISCRETE LOCALIZED AREAS OF SMALL DIMENSIONS
Comment (Commodity): PROJECT 9350 - 01393 ALUNITE RESOURCES
Comment (Production): NO ALUNITE PROD; EARLY WORKS PROSPECTING FOR GOLD ORE . GARDNER'S ( 1943 ) UNPUB. REPORT MENTIONS THERE WERE SOME SHIPMENTS OF GOLD BUT THE AMOUNT IS UNKNOWN.
Comment (Development): SEVERAL PROSPECT SHAFTS PITS SUNK IN SEARCH FOR GOLD ORE NOT ALUNITE. NO ALUNITE PRODUCED
Comment (Deposit): SOME ALUNITE DISSEMINATED THROUGH ALTERED ROCK, BUT MOST CONSPICUOUS PART OCCURS AS SMALL IRREGULAR VEINLETS. DEPOSIT IS READILY ACCESSIBLE AND THERE IS VERY LITTLE OVERBURDEN. SIZE/DIRECTIONAL DATA IS FOR ALUNITE DEPOSIT ONLY.
Comment (Location): NEAR JUNCTION OF US HIGHWAYS 93 AND 95 BETWEEN LAS VEGAS AND BOULDER CITY.
Comment (Workings): ONE 200 FT. SHAFT, A 40 FT. ADIT, A SHALLOW SHAFT, AND MANY OPEN CUTS AND PITS.
