| Deposit | IRREGULAR MASSES OF CALCITE HAVE REPLACED THE COUNTRY ROCK AND IN TURN HAVE BEEN REPLACED BY FLUORITE. LOCALLY THE REPLACEMENT EXTENDS INTO THE LIMY OR DOLOMITIC ROCKS. |
| Deposit | BECAUSE OF THE SMALL SIZE OF THE ORE BODY AND THE COST OF MINING, HAND SORTING AND SHIPPING, A MINING OPERATION WOULD BE MARGINAL AT BEST. ALL OF THE FLUORSPAR PROSPECTS IN THE AREA ARE CONFINED TO A ZONE NEAR THE SOUTHERN END OF THE BELT OF BRECCIATION. ; INFO.SRC : 1 PUB LIT |
