Comments on the geologic information

  • THE SIMILKAMEEN BATHOLITH IS COMPOSED OF HORNBLENDE GRANODIORITE, BIOTITE GRANODIORITE, PORPHYRITIC GRANODIORITE , QTZ DIORITE, AND QTZ MONZ NITE. THE SCHISTS & GNEISSES WERE DERIVED FROM PALEOZOIC SEDIMENTS & VOLCANICS THAT WERE REGIO NALLY METAMORPHOSED DURING A JURASSIC OROGENY. ELSEWHERE IN T HE DISTRICT THE PREDOMINANT ROCKS ARE TRIASSIC LIMESTONE, MAR BLE, & DOLOMITE, & PRE-TERTIARY QTZITE, METAGRAYWACKE, AMPHIB OLITE, GREENSTONE, AND METAVOLCANICS. ; GEOL.DESC: QUARTZ FISSURE VEIN

Comments on the workings information

  • THE WORKINGS EXPOSE THE VEIN ON 4 LEVELS. THE MAIN HAULAGE ADIT IS 1290 FT LONG AND INTERSECTS THE VEIN 972 FT F ROM THE ADIT PORTAL AND 440 FT BENEATH THE OUTCROP OF THE VEI N. FROM THE POINT WHERE THE ADIT INTERSECTS THE VEIN, OVERHEA D STOPES EXTEND 400 FT NO. AND 200 FT SO. WHERE THE ADIT INTE RSECTS THE VEIN, A WINZE HAS BEEN SUNK 100 FT. AT 50 & 100 F T BELOW THE WINZE COLLAR TWO WORKING LEVELS HAVE BEEN DEVELOP ED. THE UPPER ADIT, WHICH IS 200 FT ABOVE THE MAIN ADIT, INTE RSECTS THE VEIN 420 FT FROM THE ADIT PORTAL, & 200 FT BENEATH THE OUTCROP OF THE VEIN. THE ADIT CONTAINS OVER 700 FT OF DRI FTS AND A SHAFT THAT EXTENDS TO THE SURFACE. THE SHAFT CONTAI NS SEVERAL WORKING LEVELS FROM WHICH THE ORE HAS BEEN MINED.
