Comments

Comment (Commodity): ANALYSIS SHOWS STRONG ENRICHMENT IN SB, TL, AND HG, TYPICAL OF A POTENTIALLY AU- AND AG-BEARING EPITHERMAL SYSTEM

Comment (Location): LOCATION GIVEN IS THE DISCOVERY OUTCROP, WHICH CONSISTS OF MINERALIZED JASPEROID

Comment (Development): JASPEROID OUTCROPS SEEN FROM TRUCK WHILE ON RECONNAISSANCE, ONE OUTCROP FOUND TO CONTAIN VISIBLE SULFIDE, OTHER OUTCROPS CONTAINED ANOMALOUS SB, TL, AND AU GEOCHEMICAL VALUES

Comment (Deposit): DEPOSIT CONSISTS OF SULFIDE-BEARING JASPEROID. JASPEROID FORMED BY REPLACEMENT OF LIMESTONE ADJACENT TO NORTH-STRIKING FAULTS AND FRACTURE ZONES. POD-LIKE DISTRIBUTION OF JASPEROID OVER A 1 MILE STRIKE LENGTH

Comment (Workings): WORKINGS CONSIST OF ONE TINY DIGGING

Comment (Deposit): THE RARE MINERAL PARAPIERROTIE OCCURS AT THIS LOCALITY. IT WAS DISCOVERED BY X-RAY DIFFRACTION ANALYSIS BY STEVE AXON OF THE U.S. BUREAU OF MINES, SALT LAKE CITY, UTAH. PARAPIERROTITE IS A THALLIUM-ANTIMONY SULFOSALT (TLSB5S8) ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV
