Comments on the production information

  • FLUORSPAR

Comments on the workings information

  • 2 ADITS, 230 FT OF DRIFTING FROM THE NORTHERN ADIT, AND A FEW SHALLOW PITS AND CUTS. IN 1984, SEVERAL ADITS, CAVED SHAFT, OPEN STOPES.

Comments on development

  • LOCATED IN 1938, ACCORDING TO PAPKE, HOWEVER, SOME DEVELOPMENT MUST HAVE BEEN EARLIER AS EVIDENCED BY PRESENCE OF -PURPLE GLASS AND OLD ROCK FOUNDATIONS. NO ACTIVITY AT TIME OF -EXAMINATION IN 1984, BUT SURVEY CREW WAS IN THE AREA WITHIN TH-E LAST YEAR.
