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.
