Subject category Comment text
Deposit DEPOSITS CONSISTS OF JASPEROID AND SINTER-LIKE MATERIAL REPLACING LIMESTONE AND FAULT GOUGE LOCALIZED ALONG EAST-NORTHEAST TRENDING FAULTS LYING BENEATH THE SHEEPROCK THRUST. DEPOSITE IS SIMILAR TO SEDIMENT-HOSTED DISSEMINATED GOLD DEPOSITS LIKE MERCUR AND MAY HAVE POTENTIAL FOR GOLD MINERALIZATION. GEOCHEMICAL ENRICHMENT IN AS, SB, AND HG WITH TRACE AMOUNT OF AU AND AG IS SUGGESTIVE OF TOP A POTENTIALLY MINERALIZED EPITHERMAL SYSTEM.
