Economic information

Comments on the geologic information

  • GEOL.DESC: 10 CLAIMS. THE ANDALUSITE OCCURS IN A STEEP EAST FACING CLIFF COMPOSED LARGELY OF QUARTZITE, WITH THE ORE ZONE CONSISTING OF A STEEPLY DIPPING VEIN ABOUT 30' WIDE AND 2 MILES LONG. MOST OF THE ORE AVERAGES ABOUT 40% ANDALUSITE WITH LENSES OF 60% ANDALUSITE OCCURRING AT IRREGULAR INTERVALS. ONLY THE HIGHER GRADE ORE WAS MINED.

Economic information about the deposit and operations

Development status Producer
Commodity type Non-metallic
Significant No

Comments on the production information

  • 15,000 TONS FROM 1922-1945. RESERVES OF 250,000 TONS 40% ANDALUSITE REMAIN.

Comments on the workings information

  • TUNNELS AND STOPES. NO PRODUCTION SINCE 1945 BECAUSE OF HIGH COST OF MINING AND DEVELOPMENT OF SUBSTITUTES FOR ANDALUSITE.
