Comments on the geologic information

  • DIKES (CONSIDERED TO BE DERIVATIVES OF THE HERCYNIAN GRANITE MASSIF OUTCROPPING SOUTHWEST OF THE DEPOSIT) ARE INTERSECTED BY MORE THAN 70,000 THIN ORE-BEARING QUARTZ VEINS, STRIKING PREDOMINANTLY EAST-WEST. MOST DIKES STRIKE NORTH-SOUTH AND RANGE FROM 2-40M. THICK. DIKES CAN BE FOLLOWED ALONG STRIKE FOR A FEW HUNDRED METERS TO 8 KM. THE TOTAL LENGTH OF DIKES WITHIN THE ORE FIELD, COVERING AN AREA OF 64 SQUARE KM, IS 150 KM. ABOUT 40% OF THE TOTAL LENGTH OF DIKES IS PRODUCTIVE. ON THE AVERAGE EACH 3 M OF DIKE CONTAINS ONE ORE BEARING VEIN. AURIFEROUS QUARTZ-SULFIDE VEINS DEVELOPED IN THE FOLLOWING STAGES OF MINERALIZATION: 1. MILKY QUARTZ AND ANKERITE, 2. BULK SULFIDES.

Subject category Comment text
Deposit THE ORE-BEARING QUARTZ VEINS FORM A SYSTEM OF LADDER VEINS FILLING JOINTS IN DIKES. THESE VEINS RARELY CROSS THE BOUNDARIES OF DIKES. TWO GROUPS OF VEINS OF HAVE BEEN DESCRIBED: 1. VEINS OF QUARTZ-PYRITE REPRESENTING MOST OF THE AURIFEROUS VEINS, 2. VEINS OF QUARTZ-TOURMALINE. THE FIRST VEINS ARE YOUNGER THAN THE SECOND. THE AURIFEROUS VEINS OF THE FIRST TYPE ARE PRESENT AS LODES IN DIKES AND AS VEINS NOT CONNECTED WITH THE DIKES. MOST OF THE AURIFEROUS VEINS DIP AT HIGH ANGLES AND STRIKE EAST-WEST, AND ARE ASSOCIATED WITH TEAR FAULTS IN STEEPLY DIPPING DIKES OF GRANITE PORPHYRIES AND PLAGIOCLASE PORPHYRIES. THE TRANSVERSE OR LADDER VEINS STRIKE 110 SE AND DIP AT 75 TO 85 DEGREES TO THE SOUTH. THE REST OF THE VEIN SYSTEM IS ASSOCIATED WITH SHEAR FRACTURES, WHEREBY THE DIAGONAL FRACTURES PENETRATING TO GREAT DEPTH ARE CONSIDERED TO BE CONDUITS FOR MINERALIZING SOLUTIONS.
