Comments on the geologic information

  • THE YTTRIUM AND ZIRCONIUM ARE FOUND IN THE SILICATE MINERAL EUDIALYTE. EUDIALYTE IS DISSEMINATED AS A ROCK-FORMING MINERAL IN SYENITES, QUARTZ SYENITES, AND ALKALI GRANITES. HEAVY LANTHANIDE ELEMENTS ALSO ARE FOUND IN RECOVERABLE AMOUNTS IN THE DEPOSIT. ORE-GRADE MATERIAL OCCURS AT THE SURFACE AND IT EXTENDS BEYOND THE AREAS DRILLED.
