Comments on the workings information

  • THIS PROPERTY IS DEVELOPED BY A VERTICAL SHAFT IN A RHYOLITE PLUG THAT INTRUDES METAVOLCANIC ROCKS. THE SHAFT AND UNDERGROUND WORKINGS PROBABLY EXCEED 200 FEET IN TOTAL EXTENT. THE RHYOLITE IS ALTERED, WITH THE FELDSPARS AND MUCH OF THE GROUND MOSS CONVERTED TO CLAY MINERAL AND SERICITE IRREGULAR FRACTURES EXTEND THROUGH THE ROCK WITH COMMON IF ON STAINING AND SOME SILICIFICATION OF THE RHYOLITE ADJACENT TO THE FRACTURES AND WITH QUARTZ SEAMS IN SOME OF THE FRACTURES.
