Comments on the geologic information

  • THE OLYMPIC VEIN OCCURS IN RHYOLITE AND TRACHYTE COVERED IN PLACES WITH TUFF. VEIN FILLING CONSISTS OF QUARTZ AND MORE OR LESS SILICIFIED RHYOLITE. THE QUARTZ SHOWS EVIDENCE OF HAVING BEEN DERIVED FROM THE REPLACEMENT OF CALCITE. RHYOLITE AND TRACHYTE FLOWS UNDERLIE THE LAKE BEDS OF THE ESMERALDA FM.

Subject category Comment text
Deposit VEIN 1 TO 7 FEET THICK, AVERAGING 4 FEET AND CONSISTS OF QUARTZ AND SILICIFIED RHYOLITE. VEIN DIPS 40W AND FLATTENS AT DEPTH AND REVERSES TO 25E. THE BEST ORE IS CHALKY IN APPEARANCE WITH NO SIGN OF MINERALIZATION. TO THE WEST THE VEIN HAS BEEN CUT BY A FAULT, AND THE DISPLACED SEGMENT HAS BEEN LOST OF ERODED. THE GOLD IS FINELY DIVIDED AND DISSEMINATED.
