Subject category Comment text
Deposit THE VEIN SYSTEM CAN BE TRACED DIAGONALLY THROUGH SECTIONS 30 AND 19 AND ARE NW BUT PARALLEL TO THE MOHAWK VEIN. THIS PARTICULAR SET OF VEINS WERE MAPPED BY STEWART (1974) AS BEING INSIDE THE SILVER PEAK CALDERA. TONOPAH TUNNEL'S VEIN STRIKES N35E AND DIPS NEAR VERTICAL. IT MAY BE A NORTHERN EXTENSION OF THE SAME VEIN THAT THE SILVER QUEEN SHAFT WAS SUNK ON. AT THE SURFACE, THE VEIN IS REDDISH-BROWN, GOSSAN-LIKE, HIGHLY SILICIFIED AND BRECCIATED WITH PRISMATIC CRYSTALS OF BARITE UP TO 0.5 INCH LONG WITHIN THE MATRIX. BRECCIATION EXTENDS 5-6 FT INTO PORPHYRITIC LATITE AND ALONG BOTH SIDES OF THE VEIN.
