Comments on the geologic information

  • SCOSSA VEIN IS 6 FT. WIDE. A SE TRENDING DIKE INTERSECTS THE NE STRIKING 3 PARALLEL VEINS. THE DIKES AND SILICIFIED MATERIAL IN FRACTURE ZONES, APPARENTLY FORMED DURING THE PERIOD OF INTRUSION OF HIGH TEMPERATURE BARREN QUARTZ VEINLETS. THIS LOCALIZED THE DEPOSITION OF GOLD IN THE LATER LOW-TEMPERATURE GOLD-BEARING QUARTZ VEIN SYSTEM AT AND NEAR INTERSECTIONS WITH THE DIKES AND SILICIFIED ROCKS BY FORMING AN IMPERVIOUS ZONE. THE SCOSSA VEIN WAS FORMED BY SUCCESSIVE SHEARING MOVEMENTS THAT CRUSHED AND RECEMENTED THE QUARTZ. GOLD ON THE SURFACE OF THE QUARTZ WAS YELLOW BUT WAS GRAY ELECTRUM INTERGROWN WITH QUARTZ UNDER THE SURFACE.

Deposit VEINS; MODEL NAME COULD ALSO BE: POLYMETALLIC VEINS.
Deposit GOLD WAS DISCOVERED IN 1930 ON THE SCOSSA VEIN, THE MIDDLE OF 3 PARALLEL QUARTZ VEINS 1 TO 6 FT. WIDE AND TRENDING NORTHEAST. IT IS DEVELOPED BY A 400-FT. SHAFT AND 1,000 FT OF LATERAL WORKINGS. THE NORTH STAR MINE (ALONG WITH THE HAWKEYE MINE) WERE THE MOST CONTINUALLY ACTIVE MINES IN THE DISTRICT DURING THE PERIOD 1930-1939. AT THE GAYER LEASE ON THE VEIN WEST OF THE SCOSSA VEIN AND TRAVERSING THE NORTH STAR NO. 2 CLAIM, A SHAFT WAS SUNK. THE KIMBER LEASE IS ON A BLOCK OF GROUND ON THE NORTH STAR CLAIM ABOUT 500 FT. NW OF THE SCOSSA DISCOVERY WHERE AN INCLINED SHAFT 45 FT. DEEP FOLLOWS A VEINLET A FEW INCHES WIDE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
