Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Production): VALUES CHIEFLY IN AU

Comment (Geology): 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.

Comment (Development): MOST ACTIVE FROM 1918 TO 1931; SMALL RESURGENCE FROM 1937 TO 1939

Comment (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.

Comment (Workings): SHAFT 225 FEET DEEP, INCLINED 43 DEGREES, WITH 3 LEVELS
